4. Alternative Methods of Control:

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

Onion thrips Biology and Ecology. Ad ult and larval onion thrips feed on susceptible crop plants (e.g. dry bulb onion) using raspi ng-sucking mouthparts which drain cellular contents resulting in a total loss of photosynthetic area. When this occurs, cells become necrotic and enlarge into lar ge patches of dead ti ssues 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 insectici de resistance. In severe ca ses, plants can be killed by onion thrips. Multiple factors influence the severity of onion thrips infestations, but environmental conditions are the most important. When co nditions are hot and dry, onion thrips infestations are much more difficu lt to control than when conditions are cool and wet. When it is hot (e.g., 86 o 

### F), the period in which an onion thrips population completes a generation is shorte r (<2 weeks) than when it is cooler. Thus, when it is hot, several generations can be completed wi thin a short period of time leading to exponential population growth. In contrast, when conditions are cooler, generation time is decreased. In the past decade, Wisc onsin onion growers have experienced several years with these hot and dry c onditions 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 genera lly needed, whereas fewer applications are needed in cool and wet seasons. Another major problem faced by onion growers is onion thrips resistanc e 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). N early 85% of onion fields are treated with Warrior and control failures are occurring frequently. Un fortunately, no labeled insecticide works well enough to control these resistant oni on thrips populations. We suspect that resistance has developed to many of these sa me products in Wisconsin and are listed in the table below.

Shelton, A. M., B. A. Naul t, J. Plate and J. –Z. Zhao. 2003. Regional and temporal variation in susceptibility to la mbda-cyhalothrin in onion thrips, Thrips tabaci (Thysanoptera: Thripidae), in onion fields in New York. J. Econ. Entomol. 96(6): 1843-1848.

### Registered Products for Use in Wisconsin . Insecticide use is the principal tactic for controlling onion thrips infestations in onion fi elds. A list of products that are labeled for use in New York onion fields is shown below:

Pyrethroids: Ambush, Pounce 3.2 EC (permethrin) Ammo 2.5 EC (cypermethrin) Decis 1.5 EC (deltamethrin) Mustang MAX (zeta-cypermethrin) Warrior (lambda-cyhalothrin)

Carbamates : Lannate LV (methomyl) Vydate L (oxamyl) [Section 24(c) in WI]

Organophosphates : D-Z-N diazinon (diazinon) Penncap-M (methyl parathion)

Neonicotinoids: Assail 30SG (acetamiprid)

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 labele d product that is highly effective against onion thrips on onion and a label was issued in Wisconsin in the September of 2007 and was ava ilable for use in 2008. Because of its effectiveness as a thrips control product, Dow AgroSciences wants this produc t to remain viable in the marketplace for as long as possible. Thus, it is extremely important to secure registrations for different mode-of-action cla sses of chemistry to conserve the integrity of existing registrations. As indicated abov e, Wisconsin onion growers average 4 to 5 different insecticide applicati ons per season. By labeling law, onion grow ers will apply Radiant twice (maximum number suggested) dur ing the season requiring an additional 3 to 4 insecticide applications to control th rips for the remainder of the season. The problem is that there are no effective l abeled products available for these four applications.
Movento and formetanate hydrochloride (Car zol 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 thr ee highly effective products are available to control onion thrips on onion (i.e., Radi ant, 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. T he remainder of this document supports the need for Movento.Table 1.Mean (± SE) number of immature onion thrips / leaf counted on 10 plants and marketable U.S. No. 1 standard-sized bulbyield in plots treated weekly with insecticides in an onion field near Endeavor, WI (2008).Mean (± SE) Numberof Immature thrips / leafTreatmentTrtNoApplicationRateNumber ofApplications(days)1Yield(cwt / acre)2(3daa)29 July(7daa)1 August(7daa)5 August(14 daa)12 August(21 daa)19 AugustUTC1----1275.2 ± 1.56.1 ± 1.2 a6.6 ± 0.8 a5.3± 0.5 a7.1 ± 0.6 aLannate LV648.0 fl oz/ac22381.3 ± 0.31.6 ± 0.3 cd3.3 ± 0.8 c2.9 ± 0.8 d4.1 ± 0.7 bcRadiant SC76.0 fl oz/ac23120.7 ± 0.20.3 ± 0.1 d0.6 ± 0.2 de1.3 ± 0.3 d2.2 ± 0.5 bc88.0floz/ac22941.0 ± 0.20.8 ± 0.2 d0.8 ± 0.2 de0.8 ± 0.2 d-f1.3 ± 0.4 c-eVydate L932.0 fl oz/ac22311.8 ± 0.31.1 ± 0.2 d1.9 ± 0.5 de2.2 ± 0.6 ef3.8 ± 1.7 cdMovento145.0 fl oz/ac23523.2 ± 0.52.1 ± 0.5 d0.7 ± 0.3 e1.1 ± 0.3 ef0.9 ± 0.2 e158.0floz/ac23163.5± 0.51.1 ± 0.2 d0.6 ± 0.2 e1.1 ± 0.2 f0.6 ± 0.3 deCarzol SP160.5 lb/ac22871.2 ± 0.20.8 ± 0.2 cd1.3 ± 0.2 de1.5 ± 0.3 d1.8 ± 0.5 bc170.75lb/ac23161.4 ± 0.30.7 ± 0.2 cd0.9 ± 0.3 e0.9 ± 0.2 ef1.9 ± 0.4 de181.0lb/ac23401.4 ± 0.30.8 ± 0.2 d0.9 ± 0.2 de1.2 ± 0.3ef1.5 ± 0.5 cd(P<0.0001)LSD (P=0.05)-----(<0.0001)75.5(<0.0001)0.3(<0.0001)0.3(0.0295)0.7(0.0208)0.5(<0.0001)1.31Spray application dates occurred 25 July and 1 August for all treatments and date values are recorded asdays after application(daa).2Yield of standard-grade onions.

### (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 register ed 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, fa iled to control the infestation after the successive applications. In contrast, both rates of Movent o (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 registrati on of spirotetramat on oni ons 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 Agricultur al 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 sp irotetramat in the onion, which consisted primarily of spirotetramat-enol, ranged fr om <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 to lerance-level residues for all foods. Empirical and DEEMTM (ver. 7.81) default pr ocessing 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 di etary 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 subgro ups. 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 pr ocessing factors, and 100% CT was also conducted. Again, drinking water was incorporated directly into the dietary assessment

### using the chronic concentration for surfac e water generated by the FIRST model. The results of the assessment conclude that th e chronic dietary exposure estimates are below HED’s level of concern (<100% of the cPAD) for the gener al U.S. population (28% of the cPAD) and all population subgroups. The most highly exposed population subgroup is children 1-2 years ol d 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 shoul d 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 s ubgroup (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 pl antations, fruiting vegetables (crops of crop group 8), leafy vegetables (crops of crop group 4), bra ssica leafy vegetables (crops of crop group 5), and tuberous and corm vegetables (crops of crop group 1C). All risk and environmental safety considerat ions listed on the federal label will apply to this use. The Movento MSDS sheet is attached at Appendix D

.

8. Coordination with other aff ected State or Federal Agencies:
This request is being formally submitted to the U.S. Envir onmental Protection Agency (EPA) by state lead agency responsible for pesticide enforcement. This copy is also consistent with a submi ssion submitted by the New York State Agriculture and Markets.

9. Notification of Registrant : A copy of this Section 18 emergency ex emption 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 Re source Management (DARM) within the Wisconsin Department of Agri culture, Trade, and Consumer Protection (WI DATCP) is responsible for pesticide enforcement. Th e Pesticide Management Education Program at the University of Wisc onsin and the Wisconsin Cooper ative 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 ex isting 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. Se cond, there is suspected resistance to other labeled insecticides. Resistance to Warrior insect icide has been document ed in New York state (see Shelton et al. references listed abov e), 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 consecut ive applications and thus will essentially only protect the onion crop for one third of the gro wing season. In turn, there is a need for more effective products especially co nsidering the need to conserve existing registrations through adequate resistance management and rotation of active ingredients. Movento and formetanate hydrochloride (Car zol SP) are highly effective against onion thrips on onion. In addition to this Se ction 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 tw o applications per field per season. If three highly effective products are ava ilable 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 produc t 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 wild life 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. App licators 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 shoul d be used when applying next to water or where runoff is likely to occur to avoid exposu re to aquatic organisms. Spirotetramat is toxic to aquatic invertebrates and oysters; therefor e, 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.

### 4. Anticipated Economic Loss

Table 3. US No. 1 onion yield from a field trial lo cated near Endeavor, WI in 2008. Yield was adjusted to a cwt per acre basis. Bulbs were ca tegorized as jumbo, standard or boiler. Onions were harvested 16 September 2008 graded and weighed immediately in the field.

### Yield losses due to inadequate onion thrips control ha s generally been around 45% in New York State. Resu lts from the above trial clearly illustrate that when the crop was either not sprayed or sprayed with Lannat e, 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 producti on 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 indu stry stands to lose $3,160,080, or approximately one-th ird 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 resear ch completed during the 2008 growing season. Objectives outlined in this research ar e 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 manageme nt 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, po tentially efficacious insecticide foliar treatments to target problematic populations of onio n thrips. Develop efficacy data in su pport 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).

Specifically , the number of immature onion thrips larvae was recorded weekly for over 11 consecutive weeks th rough the interval 10 June through 19 August, 2009. Once the mean immature thrips popula tion 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 ra tings) 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 successi ve 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 log 10 ( 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 materi als that had the greatest overa ll impact in reducing larval densities included the novel anthrilic diamide HGW86SE, Radi ant, 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 le ss 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.Table 6.3.1.9-2: Recovery results (concurrent recoveries) for BYI08330 and its metabolites in onion bulb

Project History. Results presented here are from field research co mpleted during the 2008 growing season. Objectives outlined in this research are directly re lated to the problematic re-occurrence of onion thrips populations in Wisconsin dry bulb onion production.

Background and Rationale. Effective, economical, and efficient long te rm 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, poten tially efficacious insecticide foliar treatments to target problematic populations of onion th rips. Develop efficacy data in support of fu ture registration of novel insecticides with unique modes of action.

Experimental Design: The experiment was conducted in a single commerci al 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).

Sp ecifically, the number of imma ture 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 thresh old 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 ap plication (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 log 10 ( x

+ 1) function before analysis, and untransformed means are presen ted 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 nove l anthrilic diamide HGW86SE, Radiant, Movento, Carzol, Assa il, SpinTor, and Entrust (T able 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 ef ficacious 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 ar e summarized in Tables 6.3.1.9-3 to 6.3.1.9-4. The results from the residue trials are giv en 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 sa mpled 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.Table 6.3.1.9-2: Recovery results (concurrent recoveries) for BYI08330 and its metabolites in onion bulb
