product (0.16 lb a.i./acre) per acre per season. Applications should be made 

no less than seven days apart. 

(iv). Total Acreage to be Treated: 

A maximum of 2,200 acres will be treated in Wisconsin 

(v). Total Amount of Movento to be used: 
A total of 2,200 acres x 5.0 fl oz of formulated product x 2 applications = 22,000 

fl oz or 172 gallons of Movento. 

(vi). All Applicable Restrictions and Requirements for Use: 

Period Movento would be used: June 1 through September 15. 

Harvest Dates: August 1 through October 15. 

(vii). Other Restriction, User Precautions and Requirements: 

Worker Protection Requirements: Worker protection requirements on the 

federal label, including the restricted entry internal (REI) of 24 hours shall apply 

to this use. 

Environmental Hazards: This product is toxic to aquatic invertebrates and 

oysters. Do not apply directly to water, to areas where surface water is 

present, or to intertidal areas below the mean high water mark. This product 

may contaminate water through drift of spray in wind. Do not apply when 

weather conditions favor drift from treated areas. Drift and runoff from treated 

areas may be hazardous to aquatic organisms in neighboring areas. Do not 

contaminate water when disposing of equipment washwaters or rinsate. 

This chemical has properties and characteristics associated with chemicals 

detected in ground water. The use of this chemical in areas where soils are 

permeable, particularly where the water table is shallow, may result in ground 

water contamination. 

This product is potentially toxic to honey bee larvae through residues in pollen 

and nectar, but not to adult honey bees. Exposure of adult bees to direct 

treatment or residues on blooming crops can lead to effects on honey bee 

larvae. See “Directions for Use” section of this label for specific crop 

application instructions that minimize risk to honey bee larvae. 

In case of emergency endangering health or the environment involving this 

product, call 1-800-334-7577. If you wish to obtain additional product 

information, visit the web site at www.bayercropscienceus.com

Application Method Restrictions: Do not apply more than a total of 10 fl oz of 

Movento (0.16 lb a.i. of spirotetramat) per acre per crop or make more than 2 

applications per calendar year. 

Movento must be tank-mixed with a spray adjuvant/ additive having spreading 

and penetrating properties to maximize leaf uptake and systemicity of the active 

ingredient within treated plants; please contact your local Bayer CropScience 

representative or PCA for specific recommendations by crop. 
Pre-harvest Interval: a 7-day pre-harvest interval will be observed. 

4. Alternative Methods of Control: 

(i). Insecticide Use for Onion Thrips Control on Onion: 

Onion thrips Biology and Ecology. Adult and larval onion thrips feed on 

susceptible crop plants (e.g. dry bulb onion) using rasping-sucking mouthparts which 

drain cellular contents resulting in a total loss of photosynthetic area. When this occurs, 

cells become necrotic and enlarge into large patches of dead tissues which result 

insignificant yield loss and loss of quality due to a lack of bulbing. It is common for 

onion thrips infestations to reduce yields by as much as 25 to 50%, especially with 

increased levels of insecticide resistance. In severe cases, plants can be killed by 

onion thrips. Multiple factors influence the severity of onion thrips infestations, but 

environmental conditions are the most important. When conditions are hot and dry, 

onion thrips infestations are much more difficult to control than when conditions are cool 

and wet. When it is hot (e.g., 86o F), the period in which an onion thrips population 

completes a generation is shorter (<2 weeks) than when it is cooler. Thus, when it is 

hot, several generations can be completed within a short period of time leading to 

exponential population growth. In contrast, when conditions are cooler, generation time 

is decreased. In the past decade, Wisconsin onion growers have experienced several 

years with these hot and dry conditions resulting in onion thrips populations that have 

very challenging to control. 

During these hot and dry years, Wisconsin onion growers will apply as many as 4 

to 5 different insecticides to manage onion thrips resulting in 8 to 10 foliar applications in 

each field). In hot and dry years, more applications are generally needed, whereas 

fewer applications are needed in cool and wet seasons. Another major problem faced 

by onion growers is onion thrips resistance to insecticides. Onion producers in 

Wisconsin have experienced field control failures similar to that which has recently been 

documented In New York populations. Over the past several years, many onion thrips 

populations in New York have been documented to be resistant to pyrethroids, such as 

Warrior (Shelton et al. 2003). Nearly 85% of onion fields are treated with Warrior and 

control failures are occurring frequently. Unfortunately, no labeled insecticide works 

well enough to control these resistant onion thrips populations. We suspect that 

resistance has developed to many of these same products in Wisconsin and are listed 

in the table below. 

Shelton, A. M., B. A. Nault, J. Plate and J. –Z. Zhao. 2003. Regional and temporal 

variation in susceptibility to lambda-cyhalothrin in onion thrips, Thrips tabaci

(Thysanoptera: Thripidae), in onion fields in New York. J. Econ. Entomol. 96(6): 

1843-1848.

controlling onion thrips infestations in onion fields. A list of products that are labeled for 

use in New York onion fields is shown below:

Spinosyns: 

SpinTor 2SC, Entrust (spinosad) – for suppression only 

Radiant SC (spinetoram) –registered in WI for use in 2008 

Spinetoram (Radiant SC) is a new federally labeled product that is highly 

effective against onion thrips on onion and a label was issued in Wisconsin in the 

September of 2007 and was available for use in 2008. Because of its effectiveness as 

a thrips control product, Dow AgroSciences wants this product to remain viable in the 

marketplace for as long as possible. Thus, it is extremely important to secure 

registrations for different mode-of-action classes of chemistry to conserve the integrity 

of existing registrations. As indicated above, Wisconsin onion growers average 4 to 5 

different insecticide applications per season. By labeling law, onion growers will apply 

Radiant twice (maximum number suggested) during the season requiring an additional 

3 to 4 insecticide applications to control thrips for the remainder of the season. The 

problem is that there are no effective labeled products available for these four 

applications. 

Movento and formetanate hydrochloride (Carzol SP) are highly effective against 

onion thrips on onion. These products belong to different classes of chemistry. The 

proposed use for both Movento and Carzol SP are identical to Radiant - no more than 

two applications per field per season. If three highly effective products are available to 

control onion thrips on onion (i.e., Radiant, Movento and Carzol), with each applied a 

maximum of two times, Wisconsin onion growers will have the 6 sprays needed to 

control onion thrips for the entire season. The remainder of this document supports the 

need for Movento.

(ii). Alternative Practices for Onion Thrips Control: There are no non-insecticide 

practices that can be used successfully and economically to manage onion thrips. 

Natural enemies do not regulate populations to sub-economically damaging levels and 

most cultural practices (i.e., crop rotation, planting date adjustment, etc.) do not have a 

significant affect on populations. 

5. Effectiveness of Proposed Use: 

Field experiments were conducted in a commercial onion field in Wisconsin in 

2008 in which the efficacy of several registered products were compared with Movento for 

controlling a high infestation of onion thrips (See Appendix B for details). All products 

were applied 2 times at a weekly interval beginning on 25 July, 2008. Currently labeled 

products, Lannate and Vydate, failed to control the infestation after the successive 

applications. In contrast, both rates of Movento (5 fl oz and 8 fl oz per acre) provided an 

extremely high and consistent level of protection making it a good control option for 

Wisconsin growers. 

6. Discussion of Residues for Food Uses: 

This information was provided by Bayer CropScience and is found in Appendix 

C. Below is a summary of the pertinent information. 

Bayer CropScience conducted GLP Magnitude of the Residue trials in Europe in 

2004 and 2005 to support registration of spirotetramat on onions in Europe as well as 

an import tolerance for import of onions from Europe into the USA. IR-4 is currently 

conducting residue trials to support a Section 3 registration of spirotetramat on onions in 

the USA. The Good Agricultural Practices followed for the European residue trials 

included four application of the spirotetramat formulation at a rate of 72 g a.i./ha with a 7 

day interval and a 7 day phi. Residues of spirotetramat in the onion, which consisted 

primarily of spirotetramat-enol, ranged from <0.055 ppm (LOQ) to 0.16 ppm. 

An unrefined acute dietary exposure analysis was conducted by the USEPA for 

all uses of spirotetramat including the import tolerance for bulb onions. The detailed 

EPA HED risk assessment document is available at http://www.regulations.gov. 

The acute analysis assumed 100% CT and tolerance-level residues for all foods. 

Empirical and DEEMTM (ver. 7.81) default processing factors were used for processed 

commodities. Drinking water was incorporated directly in the dietary assessment using 

the acute concentration for surface water generated by the FIRST model. The results of 

this assessment indicate that the acute dietary exposure estimates (95th percentile) are 

not of concern to HED (<100% of the aPAD) for the general U.S. population (4.2% of 

the aPAD) and all other populations subgroups. The most highly exposed population 

subgroup is children 1-2 years old at 10% of the aPAD. 

A conservative chronic dietary assessment assuming average field-trial residues, 

empirical and DEEMTM (ver. 7.81) default processing factors, and 100% CT was also 

conducted. Again, drinking water was incorporated directly into the dietary assessment 
using the chronic concentration for surface water generated by the FIRST model. The 

results of the assessment conclude that the chronic dietary exposure estimates are 

below HED’s level of concern (<100% of the cPAD) for the general U.S. population 

(28% of the cPAD) and all population subgroups. The most highly exposed population 

subgroup is children 1-2 years old at 77% of the cPAD. 

Based on the proposed use pattern, the current onion tolerance of 0.3 ppm 

established for import of European onions should be sufficient to cover the proposed 

domestic registration of spirotetramat on onions. 

7. Discussion of Risk Information: 

Movento is currently registered by the US EPA for use on citrus fruits (crops of 

crop group 10), small fruit vine climbing subgroup (except fuzzy kiwifruit), pome fruits 

(crops of crop group 11), stone fruits (crops of crop group 12), tree nuts (crops of crop 

group 14), hops, Christmas tree plantations, fruiting vegetables (crops of crop group 8), 

leafy vegetables (crops of crop group 4), brassica leafy vegetables (crops of crop group 

5), and tuberous and corm vegetables (crops of crop group 1C). All risk and 

environmental safety considerations listed on the federal label will apply to this use. 

The Movento MSDS sheet is attached at Appendix D. 

8. Coordination with other affected State or Federal Agencies: 

This request is being formally submitted to the U.S. Environmental Protection 

Agency (EPA) by state lead agency responsible for pesticide enforcement. This copy is 

also consistent with a submission submitted by the New York State Agriculture and 

Markets. 

9. Notification of Registrant: 

A copy of this Section 18 emergency exemption request is being sent to the 

registrant, Bayer CropScience. See Appendix E for a letter from Bayer CropScience 

supporting our request. 

10. Description of Proposed Enforcement Program: 

The Division of Agriculture and Resource Management (DARM) within the 

Wisconsin Department of Agriculture, Trade, and Consumer Protection (WI DATCP) is 

responsible for pesticide enforcement. The Pesticide Management Education Program 

at the University of Wisconsin and the Wisconsin Cooperative Extension will provide 

use information to onion growers to ensure that all applicable directions and restrictions 

are followed if our request is approved. 

11. Repeated Uses: 

This is a new request. 
(b) INFORMATION REQUIRED FOR A SPECIFIC EXEMPTION: 

The use of spirotetramat on onion to manage onion thrips received an A Priority 

for the 2007/2008 IR-4 program. Subsequently, IR-4 is in the process of generating the 

appropriate information to add to the existing Section 3 registration. 

1. Pests to be Controlled

Onion thrips, Thrips tabaci Lindeman 

2. Discussion of the Emergency Situation 

Onion thrips pose a serious threat to onion production in Wisconsin because it 

can significantly reduce yields by feeding on leaves and insecticide use is currently the 

only effective tactic that can be used to control onion thrips. Thrips infestations continue 

to be difficult to control with insecticides for two primary reasons. First, no labeled 

product or combinations of products (i.e., tank mixes) are effective enough to control 

high onion thrips infestations for the entire season. High infestations occur when the 

weather is hot and dry. Second, there is suspected resistance to other labeled 

insecticides. Resistance to Warrior insecticide has been documented in New York state 

(see Shelton et al. references listed above), but we suspect that resistance has 

occurred in Wisconsin as well. 

Spinetoram (Radiant SC) received a Section 3c label for use in Wisconsin in late 

2007. Radiant is restricted to two consecutive applications and thus will essentially only 

protect the onion crop for one third of the growing season. In turn, there is a need for 

more effective products especially considering the need to conserve existing 

registrations through adequate resistance management and rotation of active 

ingredients. 

Movento and formetanate hydrochloride (Carzol SP) are highly effective against 

onion thrips on onion. In addition to this Section 18 for Movento, a Section 18 recertification has been submitted for Carzol SP. The proposed use for both Movento and 

Carzol SP will be identical - no more than two applications per field per season. 

If three highly effective products are available to control onion thrips on onion 

(i.e., Radiant, Movento and Carzol), with each applied a maximum of two times, 

Wisconsin onion growers will have the necessary applications to control onion thrips for 

the entire season. Moreover, the limited use of each product should mitigate resistance 

development. The Wisconsin onion industry, like other onion growing states, is in vital 

need of highly effective products like Movento. 

3. Anticipated Risks to Endangered or Threatened Species: 

See Appendix F for a list of endangered and threatened wildlife species in New 

York State. See Appendix D for the most recent MSDS sheet relative to spirotetramat. 
To date, we are unaware of any endangered species bulletins specifically developed for 

spirotetramat; therefore, we will work with Wisconsin DATCP personnel to identify those 

counties where problems can occur. Applicators will be advised of additional use 

restrictions, especially in those counties where endangered species reside if our request 

is granted. A buffer strip of 50 feet should be used when applying next to water or 

where runoff is likely to occur to avoid exposure to aquatic organisms. Spirotetramat is 

toxic to aquatic invertebrates and oysters; therefore, all applicable use restrictions and 

limitations on the label must be followed. This product is potentially toxic to honey bee 

larvae and should not be sprayed when bees are actively foraging.

Yield losses due to inadequate onion thrips control has generally been around 

45% in New York State. Results from the above trial clearly illustrate that when the crop 

was either not sprayed or sprayed with Lannate, yield loss averaged of 25-33% relative 

to protecting it with a highly effective insecticide like Movento. In 2007, the average 

value of summer storage onions was $12.60 per cwt (WI NASS, 2007). Thus, the 

expected gross revenue for onion production in New York using Movento and a 

registered product like Lannate have been calculated below: 

With Movento 2,200 acres x 352 cwt/acre x $12.60 = $9,757,440 

Without Movento 2,200 acres x 238 cwt/acre x $12.60 = $6,597,360

(=using Lannate) 

Therefore, without Movento, the Wisconsin onion industry stands to lose 

$3,160,080, or approximately one-third of the value of the crop. On behalf of 

Wisconsin’s onion industry, it is vital that this exemption be granted for the 2009 

growing season.

Project History. Results presented here are from field research completed during the 2008 growing season. 

Objectives outlined in this research are directly related to the problematic re-occurrence of onion thrips populations 

in Wisconsin dry bulb onion production. 

Background and Rationale. Effective, economical, and efficient long term management of both onion thrips and 

continues to be a challenge in the production of dry bulb onion. This insect pest continues to be a high pest priority 

for Wisconsin onion growers. Many of the currently registered products for control of onion thrips are not equally 

effective against the insect. As a result, thrips management is a top priority and an improved understanding of the 

ecology and management of this pest is essential towards the development of long-term control methods. 

Experimental Site: Gumz Muck Farms, Endeavor, Wisconsin. 

Project Objective: To evaluate currently registered and new, potentially efficacious insecticide foliar treatments to 

target problematic populations of onion thrips. Develop efficacy data in support of future registration of novel 

insecticides with unique modes of action. 

Experimental Design: The experiment was conducted in a single commercial muck field in the southcentral 

portion of the state of Wisconsin near Endeavor in 2007. The experiment plot was established on 3 June and 

arranged as a randomized complete block design with 4 experimental replications of foliar treatment main effects 

(Table 1).

Lannate LV, and 3) SpinTor 2SC. 
Beginning on 10 June 2008, immature onion thrips counts were initiated and destructively obtained from a subsample of growing plants in each of the treatment main effects. Specifically, the number of immature onion thrips 

larvae was recorded weekly for over 11 consecutive weeks through the interval 10 June through 19 August, 2009. 

Once the mean immature thrips population counts exceeded the established threshold of 3 immature thrips / leaf, 

foliar insecticides were applied with a 12’ boom operating at 30 psi delivering 25 gpa through 8 flat-fan nozzles 

(8004VS-XR) spaced 18” apart. Thrips counts (efficacy ratings) were made on the day of application (immediately 

prior to application) and at daily intervals of approximately 3, 7, 14, and 21 days post-application. Each insecticide 

main effect was comprised of 2 successive applications, spaced 7 days apart. The first insecticide application was 

applied 25 July and the second application applied 7 days later on 1 August. Data were analyzed using ANOVA, 

with mean separation by Fisher’s protected LSD at P <0.05. Immature thrips count data were transformed using a 

log10 (x + 1) function before analysis, and untransformed means are presented in the attached table. 

Results and Discussion: The onion thrips infestation in 2008 was initially quite low resulting from moderate 

temperatures and excessive precipitation which occurred throughout much of June. Foliar damage in the untreated 

control was evident by early to mid August with approximately 40-60% damage, or reduction in photosynthetic area 

on the leaves (e.g. defoliation). In this trial, the materials that had the greatest overall impact in reducing larval 

densities included the novel anthrilic diamide HGW86SE, Radiant, Movento, Carzol, Assail, SpinTor, and Entrust 

(Table 1). Although Lannate, Vydate, and Orthene initially reduced larval densities on the first 2 dates postapplication compared with the untreated control, the level of reduction was less than that which was observed with 

most of the efficacious treatments listed above. Among the top performing treatments, Movento, Radiant, and the 

highest rates of Carzol and Spintor (1.0 lb and 8.0 fl oz/ac, respectively) significantly reduced larval densities over 

the term of the 21 day experiment. This is likely the result of a slightly longer residual among these treatments 

compared with the lower rates of the respective compounds. The experimental anthrilic diamide (cyazypyr) HGW 

86SE performed very well in the experiment with the 5.0 and 7.0 fl oz/ac rate maintaining very adequate control of 

thrips populations. The 2 (unnamed) experimental compounds in the trial performed well through much of the field 

trial. By the 21 day post-application reading, however, only the highest rate of experimental compound #2 had 

maintained populations below the prescribed threshold (3 immature thrips / leaf).

Test system: 

Altogether 16 supervised residue trials with BYI08330 in onions were performed in the field in northern 

and southern Europe in 2004 and 2005. Applications were conducted with the OD 100 and the OD150 

formulation of BYI08330. The field data of the individual residue trials are summarized in Tables 6.3.1.9-3 

to 6.3.1.9-4. The results from the residue trials are given in Tables 6.3.1.9-5 to 6.3.1.9-6 and in more 

detail in the respective Tier I summaries. 

Residues in onions were analyzed according to method 00857 (see Point 4.3.1). Mean concurrent 

recoveries for BYI08330 and its metabolites were for all fortification levels within the acceptable range of 

70-110 %, RSD <20%. Recovery results are summarized in Table 6.3.1.9-2 

Findings: 

The total residue of BYI08330 in onion bulb ranged between <0.055 (LOQ) and 0.16 mg/kg. There was 

no difference of residues in onion bulbs grown in northern or southern Europe. 

Major component of the total residue of BYI08330 in onion sampled at the PHI of 7 days after 4 

applications of 72 g as/ha was BYI08330-enol. 

Conclusion: 

The total residue of BYI08330 in onion bulb sampled at the PHI of 7 days after four spray applications of 

72 g as/ha ranged between <0.055 and 0.16 mg/kg (STMR 0.055 mg/kg). Major component of the total 

residue in onion bulb is BYI08330-enol.

Project History. Results presented here are from field research completed during the 2008 growing season. Objectives 

outlined in this research are directly related to the problematic re-occurrence of onion thrips populations in Wisconsin dry 

bulb onion production. 

Background and Rationale. Effective, economical, and efficient long term management of both onion thrips and 

continues to be a challenge in the production of dry bulb onion. This insect pest continues to be a high pest priority for 

Wisconsin onion growers. Many of the currently registered products for control of onion thrips are not equally effective 

against the insect. As a result, thrips management is a top priority and an improved understanding of the ecology and 

management of this pest is essential towards the development of long-term control methods. 

Experimental Site: Gumz Muck Farms, Endeavor, Wisconsin. 

Project Objective: To evaluate currently registered and new, potentially efficacious insecticide foliar treatments to target 

problematic populations of onion thrips. Develop efficacy data in support of future registration of novel insecticides with 

unique modes of action. 

Experimental Design: The experiment was conducted in a single commercial muck field in the southcentral portion of the 

state of Wisconsin near Endeavor in 2007. The experiment plot was established on 3 June and arranged as a randomized 

complete block design with 4 experimental replications of foliar treatment main effects (Table 1).

Experiment combinations were directly compared to registered, industry standards including 1) Warrior 1EC, 2) Lannate LV, 

and 3) SpinTor 2SC. 
Beginning on 10 June 2008, immature onion thrips counts were initiated and destructively obtained from a sub-sample of 

growing plants in each of the treatment main effects. Specifically, the number of immature onion thrips larvae was 

recorded weekly for over 11 consecutive weeks through the interval 10 June through 19 August, 2009. Once the mean 

immature thrips population counts exceeded the established threshold of 3 immature thrips / leaf, foliar insecticides were 

applied with a 12’ boom operating at 30 psi delivering 25 gpa through 8 flat-fan nozzles (8004VS-XR) spaced 18” apart. 

Thrips counts (efficacy ratings) were made on the day of application (immediately prior to application) and at daily 

intervals of approximately 3, 7, 14, and 21 days post-application. Each insecticide main effect was comprised of 2 

successive applications, spaced 7 days apart. The first insecticide application was applied 25 July and the second 

application applied 7 days later on 1 August. Data were analyzed using ANOVA, with mean separation by Fisher’s 

protected LSD at P <0.05. Immature thrips count data were transformed using a log10 (x + 1) function before analysis, and 

untransformed means are presented in the attached table. 

Results and Discussion: The onion thrips infestation in 2008 was initially quite low resulting from moderate temperatures 

and excessive precipitation which occurred throughout much of June. Foliar damage in the untreated control was evident 

by early to mid August with approximately 40-60% damage, or reduction in photosynthetic area on the leaves (e.g. 

defoliation). In this trial, the materials that had the greatest overall impact in reducing larval densities included the novel 

anthrilic diamide HGW86SE, Radiant, Movento, Carzol, Assail, SpinTor, and Entrust (Table 1). Although Lannate, 

Vydate, and Orthene initially reduced larval densities on the first 2 dates post-application compared with the untreated 

control, the level of reduction was less than that which was observed with most of the efficacious treatments listed above. 

Among the top performing treatments, Movento, Radiant, and the highest rates of Carzol and Spintor (1.0 lb and 8.0 fl 

oz/ac, respectively) significantly reduced larval densities over the term of the 21 day experiment. This is likely the result of 

a slightly longer residual among these treatments compared with the lower rates of the respective compounds. The 

experimental anthrilic diamide (cyazypyr) HGW 86SE performed very well in the experiment with the 5.0 and 7.0 fl oz/ac 

rate maintaining very adequate control of thrips populations. The 2 (unnamed) experimental compounds in the trial 

performed well through much of the field trial. By the 21 day post-application reading, however, only the highest rate of 

experimental compound #2 had maintained populations below the prescribed threshold (3 immature thrips / leaf).

Test system: 

Altogether 16 supervised residue trials with BYI08330 in onions were performed in the field in northern and 

southern Europe in 2004 and 2005. Applications were conducted with the OD 100 and the OD150 formulation of 

BYI08330. The field data of the individual residue trials are summarized in Tables 6.3.1.9-3 to 6.3.1.9-4. The 

results from the residue trials are given in Tables 6.3.1.9-5 to 6.3.1.9-6 and in more detail in the respective Tier I 

summaries. 

Residues in onions were analyzed according to method 00857 (see Point 4.3.1). Mean concurrent recoveries for 

BYI08330 and its metabolites were for all fortification levels within the acceptable range of 70-110 %, RSD 

<20%. Recovery results are summarized in Table 6.3.1.9-2 

Findings: 

The total residue of BYI08330 in onion bulb ranged between <0.055 (LOQ) and 0.16 mg/kg. There was no 

difference of residues in onion bulbs grown in northern or southern Europe. 

Major component of the total residue of BYI08330 in onion sampled at the PHI of 7 days after 4 applications of 

72 g as/ha was BYI08330-enol. 

Conclusion: 

The total residue of BYI08330 in onion bulb sampled at the PHI of 7 days after four spray applications of 72 g 

as/ha ranged between <0.055 and 0.16 mg/kg (STMR 0.055 mg/kg). Major component of the total residue in 

onion bulb is BYI08330-enol.

RE: MoventoTM 

 Section 18 Emergency Exemption Request 

For Use on Dry Bulb Onion to Control Onion Thrips (Thrips tabaci)

 

Dear Mr. Groves;

It is our understanding Wisconsin Department of Agriculture, on behalf of onion growers in your state, 

will petition EPA for a Section 18 Emergency Exemption for the use of MoventoTM (active ingredient 

spirotetramat) on dry bulb onions to manage onion thrips. This letter is to inform you of our support of 

this Section 18 request and to confirm that sufficient quantities of Movento are available to provide to the 

onion growers in your state. 

IR-4 is currently conducting trials on onion thrips, and is expected to complete residue trials at the end of 

2009. Upon completion of IR-4 data reports, Bayer will submit a petition to EPA to add this use to the 

Section 3 label. 

A draft Section 18 label is enclosed with use directions, restrictions and requirements. If you need 

additional information or have any questions, please contact me at (919) 549-2255 or 

linda.aschbrenner@bayercropscience.com.
