I. PRELIMINARY WORK PLAN 

A. Overview 

The docket for polyoxin D zinc salt (Case 6076) is now open, initiating the first public comment period 

for this registration review case (docket number EPA-HQ-OPP-2014-0108). Seven products containing 

polyoxin D zinc salt are currently registered for use on food crops, turf and ornamentals to control 

and/or suppress fungal diseases of plants. This preliminary work plan (PWP) explains what the U.S. 

Environmental Protection Agency's (referred to as EPA or Agency in this document) Office of Pesticide 

Programs (OPP) knows about polyoxin D zinc salt, highlights its anticipated data and assessment needs, 

identifies types of information that would be especially useful in conducting the review, and provides an 

anticipated timeline for completing the registration review process for polyoxin D zinc salt. 

The registration review process was designed to include a public participation component, and by 

sharing this information in the docket, EPA intends to inform the public of what it knows about polyoxin 

D zinc salt and what types of new data or other information would be helpful to receive as it moves 

toward a decision on this biochemical pesticide. The EPA encourages all interested stakeholders to 

review the PWP and to provide comments and additional information that will help the EPA's decisionmaking process for polyoxin D.zinc salt. In addition to general areas on which persons may wish to 

comment, there are some areas identifted in the PWP about which the EPA specifically seeks comments 

and information. Interested stakeholders could include the following: environmental noriprofit or 

interest groups; pesticide manufacturers; agricultural labor or commodity groups; commercial, 

institutional, residential, and other users of pesticides; or the public at large. 

The PWP begins by describing the statutory and regulatory authorities for registration review. Next, it 

provides background information on polyoxin D zinc salt, which includes a description of its mode of 

action, the currently registered pesticide products, application rates and methods, use sites, and its 

tolerance exemption. Then, it lists the anticipated data needs, risk assessments, and a projected 

registration review timeline for this case. Finally, the PWP provides guidance for commenters, explains 

the next steps EPA will be taking, summarizes background information, and lists supporting studies, risk 

assessments, and other documents available for the registration review of polyoxin D zinc salt. 

Further information about this case, including background and supporting documents, is available at 

http://www.regulations.Qov (under "SEARCH for: Rules, Comments, Adjudications or Supporting 

Documents," enter the docket identification number, which is indicated above). 

B. Statutory and Regulatory Authority 

The Food Quality Protection Act (FQPA) of 1996 mandated a Registration Review Program. All 

pesticides distributed or sold in the United States (US) must generally be registered by the EPA, based 

on scientific data showing that they will not cause unreasonable risks to human health or the 

environment when used as directed on the product labeling. The Registration Review program is 

4 
Polyoxin D Zinc Salt EPA-HQ-OPP-2014-0108 

www.regutations.gov 

intended to make sure that, as the ability to assess risk evolves and as policies and practices change, all 

registered pesticides continue to meet the statutory standard of no unreasonable adverse effects to human 

health or the environment. Changes in science, public policy, and pesticide use practices will occur over 

time. Through its Registration Review Program, the EPA periodically reevaluates pesticides to make 

sure that, as change occurs, products in the marketplace can continue to be used safely. Information on 

this program is provided on the EPA's website. 

The EPA is implementing the Registration Review Program pursuant to Federal Insecticide, Fungicide, 

and Rodenticide Act (FIFRA) section 3(g) and will review each registered pesticide every 15 years to 

determine whether it continues to meet the FIFRA standard for registration. The regulations governing 

registration review begin at 40 C.F.R. § 155.40. The EPA will consider benefits information and data as 

required by FIFRA. The public phase of registration review begins when the initial docket is opened for 

each case. The docket is the EPA's opportunity to state what it knows about the pesticide and what 

additional risk analyses and data or information it believes are needed to make a registration review 

decision. After reviewing and responding to comments and data received in the docket during this initial 

comment period, the EPA will develop a final work plan (FWP) and the anticipated schedule for the 

registration review of polyoxin D zinc salt. 

C. Background and Regulatory Information 

i. Summary of the Active Ingredient, Usage, and Associated Pesticide Products 

Polyoxin D Zinc Salt is derived from Streptomyces cacaoi var. asoensis, a soil-borne bacterium isolated 

in Japan, and was first registered for pesticidal use in the United States on August 20, 1997 to control fungal 

diseases of turf and ornamentals. The active ingredient is produced by a fermentation process with the 

naturally occurring microorganism. The active portion of polyoxin D zinc salt is polyoxin D, a highly 

water-soluble compound; the zinc salt increases the residual time of the pesticide on plant surfaces. 

The uses of polyoxin D zinc salt were expanded on November 19, 2008 to the following food crops: 

almonds, cucurbit vegetables, fruiting vegetables, ginseng, grapes, pistachios, pome fruits, potatoes, and 

strawberries. Polyoxin D does not kill the pathogenic fungi; its pesticidal mode of action is to inhibit the 

growth of chitin in the fungal cell wall by competitively inhibiting the enzyme, chitin synthetase. 

Without chitin, the growth of the targeted fungi is halted, as is the pathogen's ability to infect its host 

plant's cells. Polyoxin D no longer acts as a fungicide when it has degraded or washed off plant 

surfaces. Since polyoxin D is specific to fungal species, other organisms (bacteria, viruses, plants, 

insects, and animals) are not affected.

D. Tolerance Actions 

Polyoxin D zinc salt is exempt from the requirement of a tolerance as follows: 

40 C.F.R. $ 180.1285: Polyoxin D zinc salt; exemption from the requirement of a tolerance. An 

exemption from the requirement of a tolerance is established for the residues of polyoxin D zinc salt in 

or on all food commodities when applied as a fungicide and used in accordance with good agricultural 

practices. 

Federal Regi.ster Citation: Final Rule (77 FR 56133, September 12, 2012). 

E. Anticipated Data Needs and Risk Assessments 

Provided below are tables of the current data requirements for biochemical pesticides as set forth in 40 

CFR § 158, subpart U. They are arrayed by scientific discipline (i.e., product chemistry, human health 

assessment, and non-target organisms and environmental fate), and descriptions are included regarding 

how the data requirements have been fulfilled or where data have been waived. At this time, no data 

gaps (anticipated data needs) for polyoxin D zinc salt have been identified. The most recent 

comprehensive risk assessment for polyoxin D zinc salt was completed in September, 2012 in support of 

amending the tolerance exemption for polyoxin D zinc salt to include all food commodities. Because 

there are no data gaps for polyoxin D zinc salt, the Agency does not anticipate the need to conduct a new 

risk assessment during registration review.

E. Risk to Threatened and Endangered Species 

Nontarget organism studies indicated that there was no toxicity to mammals and birds when exposed to 

polyoxin D zinc salt at very high doses (mammalian acute oral toxicity LD50 > 10,000 mg/kg (laboratory 

rats); mammalian 90 day oral toxicity NOAEL (female rats) and LOAEL (male rats) = 20,000 ppm; 

avian acute oral toxicity LD50 > 2150 mg/kg (mallard duck); and avian dietary LC50 > 5000 ppm 

(mallard duck)). 3Nontarget terrestrial insects were unaffected by exposure to the active ingredient at > 

400 ppm, and this is approximately lOx the highest expected residue level when polyoxin D zinc salt is 

applied at the maximum labeled use rate. Nontarget plants are not expected to be affected since 

polyoxin D is a fungal chitin synthetase inhibitor and plants do not possess this enzyme. Polyoxin D zinc 

salt was moderately toxic to both freshwater fish (96 hour LC50 = 5.06 ppm) and freshwater 

invertebrates (LC50 = 1.35 ppm) in laboratory studies; 4however, based on the application rates and the 

use patterns of the registered products, the aquatic EEC is 1.6 ppb, 3well-below the LOCs for nontarget 

aquatic organisms. Consequently, adverse effects to terrestrial and aquatic species are expected to be 

negligible and the effects determination for endangered/threatened species and designated critical habitat 

is a"No Effect." EPA anticipates conducting no further analysis of potential risks to endangered or 

threatened species, unless data or information are obtained during the registration review process that 

would indicate such an assessment would be needed to inform the Agency's decision. 

3U.S.EPA 2008. 

° U.S.EPA 1997. The Estimated Environmental Concentration (EEC) for aquatic organisms is approximately 1.6 ppb based 

on the Generic Estimated Environmental Concentration (GENEEC) model, and the terrestrial EECs range from 

approximately 9 ppm to 62 ppm on foliage (depending on the plant type), based on the Terrestrial Residue Exposure (TREX) model.

F. Endocrine Effects 

As required by the Administrator under the Federal Food, Drug, and Cosmetic Act (FFDCA) section 

408(p), the EPA has developed the Endocrine Disruptor 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 pesticide active and other ingredients) may have an effect in humans or 

wildlife similar to an effect produced by a"naturally occurring estrogen, or other such endocrine effects 

as the Administrator may designate." 

FFDCA section 408(p)(4) authorizes the Administrator, by 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 by a naturally 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 contained 58 pesticide active ingredients and 9 inert ingredients. A second list of 

chemicals identified for EDSP screening was published on June 14, 2013, 5and includes some pesticides 

scheduled for registration review and chemicals found in water. Polyoxin D zinc salt is not among the 

group of pesticide active ingredients on the lists to be screened under the EDSP. 

The EPA, as part of this PWP, believes that polyoxin D zinc salt is a substance that would not likely 

produce any effect in humans similar to an effect produced by a naturally oceurring estrogenic 

substance. As such, pursuant to Section 408(p) (4), the EPA will determine in the future whether it can 

exempt polyoxin D zinc salt 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 lists of chemicals, 

future lists, the test guidelines and the Tier 1 screening battery, please visit our website at 

http: //ivumw. epa. gov/endoA 

G. Incidents 

From March 17, 1998 through January 29, 2014, OPP's Incident Data System (IDS) indicates two minor 

human incidents from the use of pesticide products containing polyoxin D zinc salt as their active 

ingredient. There were no reported incidents to domestic animals, drinking water, surface water, 

groundwater, plants, wildlife or other non-targets. A search of OPP's Environmental Incident 

Information System (EIIS) on June 26, 2014 revealed no incidents associated with polyoxin D zine salt. 

The database contains information dating back to the 1970s. The EPA will consider any incident data or 

comments submitted in response to this PWP.

i. 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, in the development, implementation, and 

enforcement of environmental laws, regulations, and policies. To help address potential environmental 

justice issues, the EPA seeks information on any groups or segments of the population who, as a result 

of their location, cultural practices, or other factors, may have unusually high exposure to polyoxin D 

zinc salt, compared to the general population. Please eomment if you are aware of any 

subpopulations that may have atypical, unusually high exposure compared to the general 

population. 

ii. Water Quality 

Polyoxin D zinc salt is not identified as a cause of impairment for any water bodies listed as impaired 

under section 303(d) of the Clean Water Act. In addition, no Total Maximum Daily Loads (TMDLs) 

have been developed for polyoxin D zinc salt. More information on impaired water bodies and TMDLs 

can be found at the EPA's website. 6 The EPA invites submission of water quality data for pesticides 

containing polyoxin D zine salt as an active ingredient. To the extent possible, data should conform to 

6http://www.epa.gov/owow/tmdl/. 

14 
Polyoxin D Zinc Salt EPA-HQ-OPP-2014-0108 

www.regulations.gov 

the quality standards in Appendix A of the Office of Pesticide Program's (OPP) Guidance for 

Submission of State and Tribal Water Quality Monitoring Data, March 2014: Inclusion of Impaired 

Water Body and Other Water Quality Data in OPP's Registration Review RiskAssessment and 

Management Process3 to ensure they can be used quantitatively or qualitatively in pesticide risk 

assessments. 

iii. Trade Irritants 

Through the registration review process, the EPA intends to solicit information on trade irritants and, to 

the extent feasible, take steps toward facilitating irritant resolution. The EPA will work to harmonize 

tolerance and international Maximum Residue Limits (MRLs), and, if necessary, may modify tolerance 

levels to do so. Growers and other stakeholders are asked to comment on any trade irritant issues 

resulting from lack of MRLs or disparities between U.S. tolerances and MRLs in key export markets, 

providing as much specificity as possible regarding the nature of the concern. 

Pesticidal food-use of polyoxin D zinc salt is covered under an existing exemption from the requirement 

of a tolerance. Moreover, there are no known MRLs for polyoxin D zinc salt. Therefore, the EPA does 

not anticipate that current uses of polyoxin D zinc salt will pose concerns as trade irritants. 

J. Next Steps 

After the 60-day comment period closes, the EPA will review and respond to any comments received in 

a timely manner, then issue a final work plan for case 6076: polyoxin D zinc salt.
