Biopesticides Registration Action Document DRAFT **I. EXECUTIVE SUMMARY**  Background O n March 25, 2012 , W.F. Stoneman Company , LLC, on behalf of AEF G lobal, Inc. , 201, Mgr
- Bourget Levis Quebec, G6V 6Z3, Canada, submitted applications for two pesticide product s to the U.S. Environmental Protection Agency (EPA or the Agency) under section 3 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). These pesticide products, FPSolano ® Technical ( EPA File Sy mbol : 89046
- E ) , and an end

- use product (EP) , FPSolano ® ( EPA File Symbol : 89046
- R) , contain a new active ingredient (a.i.) , Clonostachys rosea strain 321U previousl y known as Gliocladium roseum strain 321U

. The application was reviewed jointly with Canada’s Pesticide Management Regulatory Agency (PMRA). Both PMRA and the EPA scientists reviewed product analysis, acute mammalian toxicology , and nontarget organism data and information (40 C.F.R. §§ 158.2120, 158.2140, and 158.2150, respectivel y) submitted to support the registration of the two proposed Clonostachys rosea strain 31U pesticide products. Summaries of these reviews are available in Appendix A in this Biopesticides Registration Action Document (BRAD). Clonostachys rosea strain 321U is a Microbial Pest Control Agent (MPCA) that is intended as an antisapstain product for control of blue stain and mold on freshly cut lumber and logs in hardwoods and softwoods. FPSolano ® Technical , which is provided as a solution, i s proposed for formulation into the wettable powder EP FPSolano ® . When applied, the pesticide displaces wild molds and staining fungi from taking up their natural ecological niches on sawn wood products and logs, thus allowing the MPCA to become established before the pest species. The MPCA metabolizes simple, non

- structural nutrients present in woody plant materials, thereby minimizing nutrients for staining fungi. Clonostachys rosea strain 321U , a fungus in the family Bionectriaceae , was isolated in Ottawa. It colonizes living plants as an endophyt e, digests material in soil as a saprophy te and is also known as a parasite of other fungi and of nematodes. Its identity was confirmed b y Dr. K.A. Seifert at the Centre of Land and Biological Resources Research (Agriculture Canada)

. Clonostachy rosea has a cosmopolitan distribution. It is common in a wide range of habitats in tropical, temperate, sub

- arctic and desert regions of the world. Ithas been reported from cultivated grassland and woodland, forest, heathland, freshwater and coastal soils. This fungus has been frequentl y associated with cysts of Heterodera sp., Globodera sp. and other nematodes in soil and with sclerotia of Sclerotnia sclerotorium, Phymatotrichum omnivorum, Rhizoctonia solani, Botryis sp., Verticillium sp. an d other soil fungi and plant materials

. For product identity , the applicant submitted adequate product chemistry data except for metabolite characterization and sto rage stability

. Three studies were conducted to address the acute dermal, acute intraperito neal injection and primary dermal irritation data requirements for the technical. Requests to waive testing for other Tier 1 acute human health toxicology data requirements were base d on the results of these studies and published information . The EPA accep ted the rationales for acute oral, acute pulmonary

toxicity and infectivity

and pathogenicity

testing for the t echnical product as well as the acute oral, primary

eye irritation. Similar rationales were submitted to waive testing for the acute toxicology

data requirements for the EP and considered adequate to support its proposed registration. A cell culture test was not required for this fungal active ingredient. The applicant reported that no hy pe rsensitivity

incidents occurred during research, development, or testing of Clonostachys rosea strain 3 2 1U . In light of the results of the acute toxicity / pathogenicity

data and information and the absence of hypersensitivity incidents, the EPA is not requiring testing at Tiers II and III (Appendix A).Clonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 5 of 29

Biopesticides Registration Action Document DRAFT The proposed use pattern is expected to limit exposure to nontarget organisms. The a.i. will be confined to dip tanks used for treatment, and is not expected to result in exposure under labeled use. Birds, wild mammals, and terrestrial plants are not expected to be exposed to Clonostachys rosea strain 321U in dip tanks, and would be expected to have very limited exposure to the a.i. that is present on freshly treated wood stored at the treatment facility . Nontarget insects and honey bees may be incidentall y exposed to freshl y treated lumber, though this exposure is also expected to be very limited. Aquatic organisms may be exposed if the treatment solution is released into the environment, such as with splash during treatment or wash

- off of the treatment during rain events. Language is present on the label to limit exposure in aquatic environments (Appendix A)

. Occupational Exposure Despite the low toxicological profile of Clonostachys rosea strain 3 2 1U , the EPA is requiring baseline personal protective equipment (PPE) for handlers who, due to their occupation, may be exposed to the active ingredient for prolonged periods and/or numerous times. Handlers working with Clonostachys rosea strain 3 2 1U in pest icide applications are directed to wear a long

- sleeved shirt, long pants, socks, shoes, waterproof gloves, protective eyewear and/or a dust/mist filtering respirator meeting National Institute for Occupational Safety and Health (NIOSH) standards of at leas t N
- 95, R
- 95, or P
- 95. For future products, the EPA may require additional/different PPE (e.g., chemical

- resistant gloves), other than the standard described above, on a product

- specific basis. Public comment On October 1, 2009, EPA announced a new poli cy to provide a more meaningful opportunity for the public to participate in major registration decisions before they occur. According to this new policy, the Agency intends to provide a public comment period prior to making a registration decision for, at minimum, the following ty pes of applications: new active ingredients; first food uses; first outdoor uses; first residential uses; and any registration decisions for which the Agency believes there may

be substantial public interest. Consistent with the new policy of making registration actions more transparent, Clonostachys rosea strain 3 2 1U is subject to a 15
- day comment period as a “new active ingredient” whose registration would result in a “first outdoor use.” While a final decision on registration is contingent upon review and consideration of public comments, the Agency presentl y believes that, based upon the preliminary risk assessment and information submitted in support of registration of Clonostachys rosea strain 321U , it is in the best interes t of the public and the environment to issue the registration for Clonostachys rosea strain 321U

. The basis for this preliminary decision can be found in the risk assessment for Clonostachys rosea strain 3 2 1U , which is characterized throughout this BRAD an d the associated reference documents written by Agency scientists.

– Fungicide See Appendix B for specific information (e.g., use sites, application rates, methods of application, formulation ty pes, and target pests) regarding the proposed labeling for pesticide products containing this active ingredient. **III . REGULATORY**  **BACKGROUND A. Applications for Pesticide Product Registration**  On March 25, 2012, William Stoneman , on behalf of AEF global, Inc., submitted applications for a manufacturing

- use pesticide product, FPSolano® Technical 100 % ( EPA File Sy mbol: 89046

- E ), and an end

- use pesticide product, FPSolano® (EPA File Symbol: 89046

- R), to the U.S. Environmental Protection Agency

(EPA) under section 3 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). These pesticide products contain a new active ingredient, Clonostachys rosea strain 3 2 1U previously

known as Gliocladiu m roseum strain 321U

. Clonostachys rosea strain 3 2 1U was the subject of a North American Free Trade Agreement joint registration review conducted b y the Environmental Protection Agency Office of Pesticide Programs and the Health Canada Pest Management Regulatory Agency
. The PMRA documents for registration of Clonostachys rosea strain 3 2 1U are under review. For further information, s ee http://www.hc

. PMRA was the leader for the health effects reviews and EPA for the ecological reviews. PMRA informed the a

pplicant of deficiencies July 27, 2012 (letter from Marion Law to Andreja Preradov). The applicant responded to the deficiencies to both PMRA and EPA on October 11, 2012

. On August 14, 2012 (77 FR 48519, EPA
- HQ
- OPP
- 2012
- 0507 ), the EPA announced receipt of these applications to register pesticide products containing a new active ingredient and opened a 30

- day public comment period pursuant to the provisions of FIFRA section 3(c)(4). No comments were received following this publication when the 30 day comment period ended. On March 5, 2013 PMRA informed the applicant of a second set of deficiencies arising out of the October 11, 2012 resubmission. The applicant responded on May 10, 2013
. These data were subject to a second completness check and were found to be sufficient to proceed with full review. The Pesticide Registration Improvement Renewal Act (PRIA II) date, originally scheduled for April 23 , 2013, was renegotiated to April 30, 2014. One study , submitted to PMRA, was not part o f EPA’s data package. When it was submitted to EPA, the PRIA date was renegotiated to June 9, 2014 to allow time for its review and incorporation into the database for this MPCA. **B .**  **Food Tolerance Exemption** No tolerance or exemption from the requirement of a tolerance is associated with or required for this regulatory

action as only

non - food uses are currently proposed for Clonostachys rosea strain 3 2 1U

. **IV. RISK**  **ASSESSMENT** In the Federal Register s of October 26, 2007 ( 72 FR 60988 ) and August 30, 2012 ( 77 FR 52610 ) , the EPA issued Final Rule s on the data requirements to support registration of microbial pesticides and updated the definition for microbial pesticides. The data and information evaluated for this BRAD were considered in light of these requirements. The classifications that are found for each data submission are assigned b y Agency science reviewers and are an indication of the usefulness of the information contained in the documents for risk assessment. A rating of “ACCEPTABLE” indicates the study is scientifically

sound and is useful for risk assessment. A “SUPPLEMENTAL” rating indicates the data provide some information that can be useful for risk assessment. The studies may have certain aspects determined not to be scientifically acceptable (“SUPPLEMENTAL : UPGRADABLE”). If a study is rated as “SUPPLEMENTAL: UPGRADABLE,” the Agency always provides an indication of what is lacking or what can be provided to change the rating to “ACCEPTABLE.” If there is simply a “SUPPLEMENTAL” rating, the reviewer will often state that the study is not required by

the current 40 Code of Federal Regulations (CFR) p art 158. Both “ACCEPTABLE” and “SUPPLEMENTAL” studies may be used in the risk assessment process , as appropriate. An “UNACCEPTABLE” rating indicates that new data need to be submitted. For the acute toxicity

data requirements, Toxicity C ategories are assigned based on the hazard(s) identified from studies and/or other information submitted to the EPA in support of a pesticide registration. The active ingredient or particular product is classified into Toxicity Category I , II, III, or IV , where Toxicity

Category Iindicates the highest toxicity and Toxicity

Category IV indicates the lowest toxicity

. **A. Product Analysis Assessment (** **40 C .**  **F .**  **R .**  **§ 158.2120 )**  The applicant fulfilled most of the product anal ys is data requirements for Clonostachys rosea strain 321U except for the storage stability data requirement

. Acceptable studies include product chemistry and composition, analysis of samples, and phy sical and chemical characteristics. Storage stability of FPSolano® (manufactured at the AEF Global Inc. site) has been evaluated over a period of three months after storage at temperatures of

- 20°C, 4°C and 20°C using the method in accordance with both PMRA’s and the EPA’s microbial pesticides data requirement s . The applicant has indicate d that additional storage stability

testing will be conducted at 6, 9, 12 and 24 months. These data must be submitted within 1 year of registration based on the potential that testing has been ongoing while the application was being processed. The label for FPSolano® proposes storage conditions of 4°C for up to four months. Based on the data submitted, FPSolano® continues to meet the guarantee after three months of storage at 4°C. However, in the absence of data, the default storage period for wettable powder formulatio ns is 6 months at 4°C. Refer to Tables 1 and 2 in Appendix A for a brief summary of the data requirements, including both generic and product

- specific information.Clonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 8 of 29

**B. Human Health Assessment**  **( 40 C**  **. F**  **. R** **. § 158.2140**  **) 1. Toxicity**  All toxicology

data requirements for non - food use of Clonostachys rosea strain 321U have been **satisfied.** Tier II and Tier III studies were not required for Clonostachys rosea strain 321U based on the lack of acute toxicity

/pathogenicity

in the Tier I studies. Refer to Table s 3 (generic

- for Technical) and 4 (product specific

- for EP) in Appendix A for a brief summary of the studies and information reviewed for the acute toxicology data requirements.
**a .**  **Endocrine Disruptors** As required by

the Administrator under FFDCA section 408(p), the EPA has developed the Endocrine Disru ptor Screening Program (EDSP) and has begun to implement the screening program that is to be used to test all pesticides in order to determine whether certain substances (including pestic ide active and other ingredients) may have an effect in humans or wildlife similar to an effect produced by a “naturall y occurring estrogen, or other such endocrine effects as the Administrator may designate.” FFDCA section 408(p)(4) authorizes the Administrator, b y order, to exempt from the requirements of the Estrogenic Substances Screening Program a biologic substance or other substance if a determination is made that the substance is not anticipated to produce any effect in humans similar to an effect produced b y a naturall y occurring estrogenic substance. Between October 2009 and February 2010, the EPA issued test orders/data call

- ins for the first group of 67 chemicals, which contains 58 pesticide active ingredients and 9 inert ingredients. Clonostachys rosea strain 321U is not among the group of 58 pesticide active ingredients on the initial list to be screened under the EDSP. The EPA believes that Clonostachys rosea strain 321 U , the active ingredient described in this document, likely is a substance that would not produce any effect in humans similar to an effect produced b y a naturally occurring estrogenic substance. As such, pursuant to Section 408(p)(4), the EPA will determine in the future whether it can exempt Clonostachys rosea strain 321 U from the requirements of the Section 408(p) EDSP. In the event the EPA does determine to exempt this substance from the EDSP, an order will be issued. For further information on the status of the EDSP, the policies and procedures, the list of 67 chemicals, the test guidelines and the Tier 1 screening battery, please visit our website at http://www.epa.gov/endo/

. **2. Federal Food, Drug, and Cosmetic Act (FFDCA) Considerations** No tolerance or exemption from the requirement of a tolerance is associated with or required for this regulatory

action as only

non - food uses are currently proposed for Clonostachys rosea strain 3 2 1U
. Accordingl y, this action is outside the scope of the Food Quality Protection Act (FQPA). There are no CODEX maximum residue levels established for Clonostachys rosea strain 3 2 1U
.Clonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 9 of 29

Biopesticides Registration Action Document DRAFT **3 . Occupational Exposure and Risk Characterization**  Handler exposure to Clonostachys rosea strain 321U is not expected to pose any undue risk. Regardless, the EPA is requiring appropriate personal protective equipment and precautionary statements on pesticide product labels to mitigate any potential risks to pesticide handlers due to prolonged and/or repeated exposures. Handlers working with Clonostachys rosea strain 321U for uses as labeled are directed to wear a long

- sleeved shirt, long pants, socks, shoes, waterproof gloves, protective eyewear, and /or a dust/mist filtering respirator meeting NIOSH standards of at least N

- 95, R
- 95, or P
- 95. For future products, the EPA may require additional/different PPE (e.g., chemical

- resistant gloves ), other than the standard described above, on a product

- specific b asis.
**C. Environmental Assessment**  **( 40 C**  **. F**  **. R** **. §**  **158.2150 )**  **1 .**  **Nontarget Organism Toxicology** All nontarget toxicology

data requirements for Clonostachys rosea strain 321U have been satisfied. Adequate Tier I nontarget organism data /information are available to support registration of Clonostachys rosea strain 321U

. The EPA found that guideline studies and scientific rationale submitted by

the applicant are sufficient to fulfill the nontarget organism data requirements and for risk assessment purposes. Further testing of nontarget organisms at higher tier levels (i.e., Tiers II, III, and IV ) is not required. The EPA performed an environmental risk assessment, based on information provided b y the applicant, and determined that no effects are anticipated for nontarget species exposed to Clonostachys rosea strain 321U as a result of the proposed labeled applications. Refer to Table 5 in Appendix A for a brief summary of the review of the data/information submitted for these data requirements. For a summary

of the generic data requirements described in sections IV(C)(1), refer to Table 7 in Appendix A

. **2 .**  **Ecological Exposure and Risk Characterization** Clonostachys rosea is a cosmopolitan microorganism. It is purported to be very common in soil and on organic matter; however, since it has not been the subject of much field research, field collections of this fungus are limited. In Canada, isolates of this species that have been deposited in culture collections have been collected from British Columbia, Alberta, Ontario and Quebec. Moreover, Clonostachys rosea is common in a wide range of habitats in tropical, temperate, subarctic, and desert regions of the world. It was r eported in cultivated, grassland, woodland, forest, heathland, freshwater, and coastal soils, particularl y those of neutral to alkaline pH, and is not known to produce any adverse health or environmental effects (Pugh and Dickinson, 1965; Foley and Deacon, 1985; Sutton et al., 1997). **3 .**  **Environmental Fate Data** As the information provided is sufficient to both satisfy the Tier I nontarget organism data requirements and for nontarget organism risk asse ssment for Clonostachys rosea strain 321U , further te sting at higher tier levels (i.e., Tiers II, III, and IV) is not required

.Clonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 10 of 29

Biopesticides Registration Action Document DRAFT **4 .**  **Threatened and Endangered**  **Species Assessment** The EPA has determined that no effects are anticipated for nontarget species exposed to Clonostachys rosea strain 321U as a result of the proposed labeled applications. Therefore, a “No Effect” determination is made for direct and indirect effects to federall y listed endangered and threatened (“listed”) species and for their designated critical habitat.
**V. ENVIRONMENTAL JUSTICE**  The EPA seeks to achieve environmental justice

—the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income

— with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies. Fair treatment means that no group of people, including racial, ethnic, or socioeconomic groups, should bear a disproportionate share of the negative environmental consequences resulting from industrial, municipal , and commercial operations or the execution of federal, state, local, and tribal environmental programs and policies. Meaningful involvement means that (1) potentially affected community

residents have an appropriate opportunity

to participate in decision s about a proposed activity that will affect their environment and/or health; (2) the public’s contribution can influence the regulatory agency’s decision; (3) the concerns of all participants involved will be considered in the decision

- making process; and (4) the decision

- makers seek out and facilitate the involvement of those potentially affected. The EPA has this goal for all communities and persons across the United States. To help address potential environmental justice issues, during the 15

- day publ ic participation comment period, the EPA sought information on any groups or segments of the population who, as a result their location, cultural practices, or other factors, may have atypical, unusually high exposure to Clonostachys rosea strain 321U , compared to the general population. The EPA received no public comments on this particular matter

. For additional information regarding environmental justice issues, please visit the EPA’s web site at http://www.epa.gov/compliance/environmentaljustice/ind ex.html

. **V I**  **. RISK MANAGEMENT DECISION**  Section 3(c)(5) of FIFRA permits for the registration of a pesticide provided that all the following determinations are made: (1) Its composition is such as to warrant the proposed claims for it; (2) Its labeling and other material required to be submitted comply with the requirements of FIFRA; (3) It will perform its intended function without unreasonable adverse effects on the environment; AND (4) When used in accordance with widespread and commonly recognized practice, it will not generall y cause unreasonable adverse effects on the environment. To satisfy criterion 1, the EPA understands that Clonostachys rosea strain 321U is wel l

- known to haveClonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 11 of 29

Biopesticides Registration Action Document DRAFT fungicidal capabilities

. The EPA has no knowledge that would contradict the claims made on the FPSolano® biological fungicide labels, and the proposed pesticide products are not expected to cause unreasonable adverse effects on the environment when used according to the ir respective label instructions. Criterio n 2 is satisfied by the product labels, as well as the data and information presented in this document. It is believed that the Clonostachys rosea strain 321U pesticide products will not cause any unreasonable adverse effects on the environment, and FPSolano® biological fungicide ( end

- use pesticide product) , in particular, is likel y to control certain fungi as claimed, satisfying criterion 3. Criterion 4 is satisfied in that the Clonostachys rosea strain 321U pesticide products are not expected to cause unreasonable adverse effects when used according to label instructions. Therefore, the EPA believes FPSolano® Technical and FPSolano® biological fungicide , containing the Clonosta chys rosea strain 321U as a new active ingredient, are eligible for registration under FIFRA section 3(c)(5) for the labeled uses. **V I**  **I .**  **ACTIONS REQUIRED OF**  **THE REGISTRANT A.

**(40 .**  **F .**  **R .**  **PART 158** 

**– SUBPART**  **V )**  **A. Product Analysis**  The applicant fulfilled most of the product anal ys is data requirements (except for the storage stability data requirement) for Clonostachys rosea strain 321U , including product chemistry and composition, anal ys is of samples, and phy sical and chemical characteristics, by acceptable guideline studies (Tables 1 and 2, Appendix A). The original submission package referred to the MPCA as Gliocladium roseum strain 321U. Gliocladium roseum was reclassified as Clonostachys rosea , because G. roseum differed from the type species of Gliocladium, G. penicillioides , in morphology , ecology , teleomorph, and DNA sequence data. Therefore, the MPCA is to be referred to as Clonostachys rosea strain 321U

. Gliocladium catenulatum has also been transferred to the genus Clonostachys and is known as C. rosea f. catenulata . The relationship between Gliocladium and Clonostachys is therefore considered close. Furthermore, the Gliocladium genus is closely related to the Trichoderma genus. For example, G. virens has been rec lassified as T. virens . As a result, information on various Gliocladium and Trichoderma species are considered in this review. The MPCA is permanently stored in liquid nitrogen in the Forintek Culture Collection and has also been deposited at the Centrallbureau voor schimmelcultures (BS 226.48) and the American Ty pe Culture Collection (ATCC 10406). The taxonomic designation of the microbial pest control agent (MPCA) is as follows ( MRID 49172001 ): Kingdom Fungi Phylum Ascomycota Class Sordariomycetes Order Hypocreales Family Bionectriaceae Genera Clonostachys Species rosea Strain 321U Product identity Clonostachys rosea strain 321U can be distinguished from species belonging to the closel y related Gliocladium genus b y m orphology . Sequencing of the internal transcribed spacer (ITS) can be used to distinguish the active ingredient from other Clonostachys species and other strains of C. rosea
. Unintentional Ingredient anal ys is Results of microbial contaminant testing for five batches of TGAI and five batches of EP (manufactured at the AEF Global Inc. site) were provided ( MRID 49172001 ). Anal ys es of the total Mesophiles, total coliforms, fecal coliforms, fecal Enterococci and Sta phylococci were acceptable (<10 cfu/mLfor the Technical and <10 cfu/g for the EP). Although testing for Salmonella and Shigella species is not routinely conducted as part of the manufacturing process/quality assurance protocol, testing was carried out on five batches of EP using Health Canada protocols MFHPB

- 20 and MFLP
- 25 that include an enrichment step (MRID 49172001 ). Results provided for five batches of the TGAI and EP demonstrated that they were absent.Clonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 18 of 29

Biopesticides Registration Action Document DRAFT
These m icrobial contaminant anal ys is data submi tted for batches of FPSolano produced at the primary manufacturing and formulating site were acceptable for the registration of the pesticides . Additional microbial contaminant analysis data on batches produced at the secondary manufacturing and formulating sites will be required. **B. Biological Properties of the MPCA(s):**  1. Natural Occurrence of the Microorganism : Clonostachy rosea has a cosmopolitan distribution. It is common in a wide range of habitats in tropical, temperate, sub

- arctic and desert regions of the world. It has been reported from cultivated grassland and woodland, forest, heathland, freshwater and coastal soils. This fungus has been frequentl y associated with cysts of Heterodera sp., Globodera sp. and other nematodes in soil and with sclerotia of Sclerotnia sclerotorium, Phymatotrichum omnivorum, Rhizoctonia solani, Botryis sp., Verticillium sp. and other soil fungi and plant materials (MRID 49172001)

. 2. Target Organisms : The MPCA is intended as an antisapstain product for control of blue stain and mould on freshly cut lumber and logs in hardwoods and softwoods. Target organisms on which the MPCA has been tes ted include Ophiostoma piceae 387E, Aureobasidium pullulans 132S, Ceratocystis adiposa 251E, Alternaria alternata 2G, Cladosporium sphaerospermum 806B, Hormonema dematioides 742D, Rhinocladiella atrovierens 135E, O. minus 864A, Phialophora botulispora 707C and O. piliferum 55B (MRID 48978901). The end

- use product, FPSolano, is mixed with an alkaline solution prior to the wood being treated. The wood staining fungi are susceptible to alkaline conditions while the MPCA is unaffected b y high pH. The alkalin e solution displaces wild moulds and staining fungi from taking up their natural ecological niches on sawn wood products and logs allowing the MPCA to become established before the pest species. The MPCA metabolises simple, non

- structural nutrients present in woody plant materials, thereb y minimizing nutrients for staining fungi (MRID 48978901). The antagonistic behaviour of C. rosea/ G. roseum towards other fungi has also been attributed to mycoparasitism, substrate competition, enzy matic activity

(e.g., β1

- 3 glucanases,, chitinases) and induced resistance. Moreover, production of toxic secondary metabolites may

also exert an antibiotic effect ( MRID 49172001 ). 3. Host Range: The host range of C. rosea includes Acacia, Acer, Beta, Buxus , Cucumis, Daucus, Fragaria, Liquidambar, Lycopersicon, Metrosideros, Phaseolus, Phoenix, Pinus, Poncirus, Psilotum, Quercus, Rhizophora, Trifolium, citrus and gl ycine (MRID 48978901).Clonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 19 of 29

**C. Acute mammalian toxicology**  Tier I mammalian toxicology data/information are sufficient for the registration of Clonostachys rosea strain 321U (see Tables 3 and 4 below)

. Three studies were conducted for the acute dermal, acute intraperitoneal injection and primary dermal irritation data requirements for the technical. The infectivity

/pathogenicity

endpoints were not addressed by the studies conducted for the acute dermal and acute injection guidelines

. The test substances used in these studies were not representative of the technical or the end

- use product (i.e., low level of active ingredient and no formulation ingredients added). Furthermore, the test substances used in these studies were liquid formulations whereas the end

use product is a wettable powder which may pose a greater potential for eye irritation. In lieu of conducting acute oral and acute pulmonary infectivity

/toxicity studies, the applicant has provided waiver rationales based on the results of the three above

- mentioned studies, in addition to the mouse IP batch anal ys is studies, a literature search, the practices and design features employed in anti

sapstain facilities and the nature of the formulation ingredient. A similar rationale, the findings of a review paper and the use of PPE were found acceptable to waive testing for the primary eye irritation study . Appropriate PPE is required to mitigate potential skin sensitization that may be due to substances p roduced b y all microorganisms that can elicit allergic reactions after repeated exposure to high concentrations. Requests to waive toxicology testing for the EP were accepted based on the foregoing studies and rationales submitted. No hy persensitivity

in cidents, including immediate

- ty pe or delayed

- ty

pe reactions of humans and domestic animals, occurred during research, development, or testing of Clonostachys rosea strain 321U . Any future hypersensitivity incidents must be reported to the EPA (refer to tes t note #3 of 40 C.F.R. § 158.2140(d)). A cell culture study

is not required because Clonostachys rosea strain 321U is not a virus (refer to test note #4 of 40 C.F.R. § 158.2140(d)).Clonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 21 of 29

885.3050 (waiver request) Ac ute Oral Toxicity/Pathogenicity (waiver request based on IP, dermal, mouse IP batch analysis and nature of formulation ingredient) Waiver rationale based on the results of an acute IP injection, acute dermal toxicity, dermal irritation and mouse IP batch analysis s tudies, a literature search, the practices and design features employed in anti

- sapstain facilities and the nature of the formulation ingredient. In lieu of acute oral pathogenicity testing, the registrant submitted a scientific rationale to waive testing

. No signs of toxicity were noted in rats acutely exposed by IP injection to a 5.0×10 6 CFU/animal dose of C. rosea strain 321U. Infectivity was not assessed in this study although no signs of pathogenicity were observed. Results from a mouse IP batch analysis were also submitted in which no signs of adverse effects were observed amongst mice dosed with at least 10 6 CFU of C. rosea strain 321U via IP injection. Clonostachys rosea strain 321U was not toxic or irritating via the dermal route although the test material used was lower in toxicity than both the TGAI and the EP. As well, there were no incidents of pathogenicity/infectivity or other deleterious effects to mammalian species due to Clonostachys or Gliocladium reported in the public scientific literature. There were a number of cases of infections or adverse effects in immunocompromised individuals due to species of the related genus Trichoderma

. Toxicological studies on toxins and enzymes associated with Trichoderma species used purified forms of these substances whose levels are unlikely to be encountered under the proposed manufacturing process of use scenario. In addition to the toxicology database, the registrant also cited the design and practices em ployed at anti

- sapstain facilities that are designed to minimize exposure. The formulation ingredient does not pose a concern. The EP is not intended for use on food or feed crops. **WAIVER ACCEPTED TOXICITY CATEGORY II**  **I -**  **Classification: Acceptable**  48782605

Biopesticides Registration Action Document DRAFT **D. Ecological Effects**  Environmental Exposure The proposed use pattern is expected to limit exposure to nontarget organisms. The a.i. will be confined to dip tanks used for treatment, and is not expected to result in exposure under labeled use. Birds, wild mammals, and terrestrial plants are not expec ted to be exposed to C. rosea strain 321U in dip tanks, and would be expected to have very limited exposure to the a.i. that is present on freshl y treated wood stored at the treatment facility . Nontarget insects and honey bees may be incidentally

exposed to freshl y treated lumber, though this exposure is also expected to be very limited. Aquatic organisms may be exposed if the treatment solution is released into the environment, such as with splash during treatment or wash

- off of the treatment during rain events. Language is present on the label to limit exposure in aquatic environments. **Summary of Nontarget Effects**  **Data** Table 5 provides the status of the nontarget organism data requirements for the active ingredient, Clonostachys rosea strain 321U, required under 40 CFR§ 158.2150. AEF Global submitted guideline studies to address toxicity /pathogenicity

in birds, freshwater fish, and freshwater invertebrates, and submitted scientific rationale to address toxicity /pathogenicity

in wild mammals, nontarget insects and honey bees, and terrestrial and aquatic plants. Data Evaluation Records for these studies and rationale were completed through joint review with Canada’s Pesticide Regulatory Management Agency (PMRA). EPA determined that the in formation provided is sufficient to satisfy the nontarget organism data requirements for this new a.i. and its proposed uses. Additional testing at higher tiers is not required for the proposed uses

Biopesticides Registration Action Document DRAFT treatment of wood contained in dip tanks. The label also contains sufficient language to limit environmental release and exposure to birds and mammals. Studies that were submitted did not show toxicity or pathogenicity

in these animals; however, the studies were determined to have limited use for risk assessment. Since e xposure is expected to be minimal, adverse effects to birds and mammals are not expected as a result of the proposed use of C. rosea strain 321U, as labeled. Nontarget Insects and Honeybees Data in the public literature indicate that Clonostachys rosea is a potential entomopathogen (Toledo et al. 2006, Vega et al. 2008). Insects may be exposed if they

contact treated wood; however, while most of this exposure is likely

to be incidental, some insects may be attracted to freshly

treated wood as a potenti al water source while it is still wet. Since freshly treated wood will be limited to these treatment facilities and not widespread in the environment, such exposure is expected to be minimal and to have little impact on nontarget insect and honey bee popul ations. Therefore, adverse effects to nontarget insects and honey

bees are not expected. Rationale presented b y AEF Global to address nontarget data requirements included a proposal to include a label statement requiring users to cover freshly treated wo od. This statement was part of EPA’s and PMRA’s consideration in acceptance of this rationale. While exposure to nontarget insects and honey

bees may be limited, requiring users to cover freshl y treated wood would reduce exposure further and also any uncertainty about risk due to the potential for effects on insects. It is recommended to include this requirement on the label. Freshwater Fish and Invertebrates Studies submitted in support of this registration indicated adverse effects on survival in freshwater fish and survival, reproduction, and growth in freshwater invertebrates with exposure to C. rosea strain 321U. Exposure in aquatic environments could occur through splashing during treatment, spills, washing of treatment equipment, or wash

- off of tre ated materials during rain events. Such exposure is expected to be limited, since these events would only occur at the lumber yard where the wood is treated, and these sites are likely limited within any

landscape. Therefore, adverse effects to freshwater fish and invertebrates are not expected due to minimal exposure. The label contains language that is expected to sufficientl y limit exposure through these types of releases into the environment. Rationale submitted as a supplement to the freshwater fish and invertebrate studies provided information on clean

- up of spills, including application of a 5% bleach solution for one hour to the spill location. While the label does acknowledge that spills and splash are the responsibility

of the applicator, it is recommended that the label provide information to the user on proper clean

- up of spills so that environmental exposure is minimized. Label language requiring freshly treated lumber to be covered was also proposed in this rationale, and was considered in EPA ’s and PMRA’s acceptance of this rationale. This language is also recommended, since this would prevent wash

- off of the C. rosea strain 321U. Marine/Estuarine Fish and Invertebrates Exposure in marine/estuarine environments is not expected to be signif icant. Use of the EP is limited to facilities that cut or chip wood, and the product is applied by use of a dip tank. Exposure in nearby aquatic areas is expected to be limited, and any exposure in marine or estuarine sites would be furtherClonostachys rosea strain 321U previously known as Gliocladium roseum strain 321U Page 28 of 29

Biopesticides Registration Action Document DRAFT minimized by

additional dilution within these larger water bodies. Therefore, adverse effects are not expected in marine/estuarine fish or invertebrates as a result of the use of C. rosea strain 321U, as proposed. Terrestrial and Aquatic Plants Exposure to terrestrial and aquatic plants is also expected to be limited as a result of the use pattern and limited exposure. Some data were also submitted showing no observed adverse effects in cabbage, lettuce, and tomato plants. L abel statements that limit any potential run

- off from treated lumber would further reduce exposure in aquatic environments. Based on the use pattern limiting exposure and expected lack of effects, risk to terrestrial and aquatic plants is not anticipated as a result of the proposed uses of C. rosea s train 321U, as labeled. **Threatened and Endangered Species Assessment** Since EPA has determined that no effects are anticipated for nontarget species exposed to Clonostachys rosea strain 321U as a result of the proposed labeled uses, effects to federally listed threatened and endangered species and their designated critical habitats are also not expected. Therefore, a “No Effect” determination is made for direct and indirect effect s to federall y listed threatened and endangered species and their designated critical habitats for the proposed use of Clonostachys rosea strain 321U. **Conclusions** Adverse effects to nontarget organisms are not expected as a result of the proposed use o f C. rosea strain 321U. Rationale submitted to support the registrations of products containing this a.i. proposed label language requiring that users cover freshly treated wood to prevent exposure to nontarget organisms. This language is not on the latest proposed label for the EP, but is recommended for inclusion on the label reduce any potential exposure to nontarget aquatic organisms, insects, and honey bees and any uncertainty with these risk conclusions. The label should also include guidance on proper clean

- up of C. rosea strain 321U that may spill or splash during treatment. **References** Toledo, A.V., Virla, E., Humber, R.A., Paradell, S.L ., Lopez Lastra, C.C. 2006. Journal of Invertebrate Pathology
