1. Executive Summary

Thiamethoxam is a systemic insecticide registered for use on numerous crops such as grain 

cereals, vegetables, oilseeds, fruits, turf, soybean, and ornamentals for the control of 

commercially relevant sucking and piercing insects that feed on the vascular tissue of crop 

plants. The proposed action is to register thiamethoxam as a seed treatment for use on dry bulb 

onions at the rate of 0.18 lb a.i./acre and peanuts at a rate of 0.08 lb a.i./acre. In addition, this 

assessment characterizes potential risks associated with increased rates and/or application of

thiamethoxam as a seed treatment rather than a foliar spray on crops including carrots, leafy 

vegetables, and brassica (cole) leafy vegetables. Finally, corn is also included in this assessment 

as it does not appear to have been assessed by EFED at any application rate or method

previously. 

A number of risk assessments have been conducted on thiamethoxam. Previous assessments 

have identified potential risks primarily to terrestrial and aquatic invertebrates, although 

potential for risk also exists for birds and mammals. Because thiamethoxam is systemic and 

persistent, particular concern for non-target beneficial arthropods, including pollinators, has 

been identified (DP357206, May 18, 2009). Additionally, potential risks to aquatic 

invertebrates due to exposure to the degradate CGA-322704 (clothianidin) have been 

identified. Taxonomic groups for which concern levels were exceeded for the assessed uses 

are summarized in Table 1.

b

RQs were not calculated due to lack of quantification methodology. Therefore, the ‘LOC exceedance’ was 

based on application rate, toxicity data, and the mode of action of thiamethoxam. 

2. Use Characterization

The registrant has proposed to register thiamethoxam as seed treatments on dry bulb onions at 

the rate of 0.18 lb a.i./acre (Cruiser 70WS) and peanuts at the rate of 0.08 lb a.i./acre (Cruiser 

5FS and Cruiser PD). Application is assumed to be limited to ground as treated seed must be 

incorporated to a depth of at least one inch. Table 2 summarizes the proposed new uses, which 

are denoted by a single asterisk. Table 2 also includes uses on the submitted labels that have 

been previously registered but do not appear to have been assessed by EFED or not assessed at 

the current rate and/or application method. These uses included in the quantitative portion of this 

risk assessment are denoted by a double asterisk. 
4

Uses listed in Table 2 that are not denoted by either a single or double asterisk are not included 

in this assessment. However, these uses may need to be re-evaluated after the current labels are 

revised to provide crop-specific application rates. 

 

Cruiser 70WS is a wettable powder that is tank-mixed with water. It is packaged in water-soluble 

bags, which are added, unopened, to the mixing tank. Cruiser 5FS is a water-based slurry that is 

diluted with water and applied to the seed using standard slurry seed treatment equipment. 

Cruiser PD is a wettable powder that was developed for dry application to peanut seed. The 

Cruiser PD label does not state that a seed sticker must be used. Use of a seed sticker would 

presumably reduce the amount of thiamethoxam that may leave the seed in dust particles during 

planting.

The California crop profile indicates that, typically, 4-5 lb onion seed are planted per acre. The 

registrant assumes that 3 lb onion seed/acre are planted (406,000 seeds/acre ÷ 136,000 seeds/lb). The 

estimated rate was obtained as follows: 0.18 lb a.i./acre ÷ 3 lb seed/acre * 5 lb seed/acre = 0.30 lb 

a.i./acre.

2.1. Scope of Assessment

This assessment considers thiamethoxam and one degradate of concern (clothianidin) for aquatic 

animals. Clothianidin is of similar or less toxicity to terrestrial animals compared to

thiamethoxam; therefore, potential risks were not quantified for terrestrial animals resulting from 

exposure to this degradate. This assessment follows an abbreviated format because a full 

assessment was completed recently (DP357206, May 18, 2009), and risk conclusions are similar 

to previous assessments. Two new studies have been reviewed, and the results are presented in 

Section 4; however, neither study produced toxicity values that could be used quantitatively in 

this risk assessment.

2.2 Nature of the Chemical Stressor

Thiamethoxam is very soluble (4100 mg/L) in water. The vapor pressure (4.95 x 10-11 mm Hg) 

and Henry's Law Constant (4.65 x 10-15 atm m3/mol) indicate that the compound is relatively 

non-volatile under field conditions. The compound does not dissociate within the range of pH 2 

to 12. All fate data requirements for thiamethoxam are fulfilled except for the bioaccumulation 
6

fish study (165-4) for which a waiver has been requested (U.S. EPA, 2006). However, the noctanol water partition coefficient (Log Kow = -0.13) for thiamethoxam indicates a low potential 

for bioaccumulation. 

The principal routes of dissipation for thiamethoxam are photodegradation in water, alkalinecatalyzed hydrolysis, and leaching. Other probable routes of dissipation are aerobic aquatic 

metabolism and foliar absorption. Aerobic aquatic metabolism is considered a probable route of 

dissipation based on the different rates of degradation of thiamethoxam in terrestrial and aquatic 

environments; thiamethoxam had substantially lower half-lives (13.8 to16.8 days) in aerobic 

aquatic environments as compared to aerobic soil environments (112 to 408 days). This apparent 

difference in the persistence of thiamethoxam in terrestrial and aquatic environments is likely to 

be due to hydrolysis under alkaline pH conditions in the aerobic aquatic metabolism study. 

Additionally, root uptake, leaching, and foliar absorption are expected to be a probable route of 

dissipation because thiamethoxam is a systemic insecticide with an extremely low partitioning 

coefficient.

Additional environmental fate data can be found in the earlier assessment (DP357206, May 18, 

2009).

3. Exposure Summary

3.1. Terrestrial Exposures

T-REX v1.4.1 was used to estimate potential exposures to birds and mammals. Estimated 

concentrations of thiamethoxam to which birds and mammals could be exposed via consumption 

of treated seed are in Table 3. Additionally, Table 3 includes an estimate of available active 

ingredient per square foot to which birds and mammals could be exposed. EECs used to calculate 

risk quotients for birds and mammals that may consume treated seeds are based on the 

concentration of thiamethoxam on treated seeds. These EECs are limited by the fact that the 

labels indicate the amount of a.i. to be applied (in mg) per seed. There is a large range of seed 

sizes as well as differences in optimal seeding rates; therefore, the concentration of 

thiamethoxam on seeds may vary depending on the size of the seed, and the application rate (lb 

a.i/acre) may vary considerably depending on the seeding rate used. Therefore, there are 

uncertainties as to the actual doses that would be available to terrestrial animals via consumption 

of treated seeds. Due to these uncertainties, EECs could over- or under-estimate exposures and 

risks. However, inputs resulting in high-end exposures were used for this assessment. For 

example, if a label specifies the mg a.i. to be applied per seed and the maximum lb a.i. to be 

applied per acre, the number of seeds planted per acre would remain constant. A minimum 

seeding rate (in terms of lb seed to be planted per acre) would increase exposure because only 

the size (weight) of the seed varies. A greater number of small seeds would have to be consumed 

to satisfy dietary requirements of birds and mammals in comparison to large seeds, thus 

increasing the amount of a.i. consumed (e.g., 5 large seeds * 0.29 mg a.i./seed = 1.45 mg a.i. 

consumed vs. 10 small seeds * 0.29 mg a.i./seed = 2.90 mg a.i. consumed). If labels were to 

specify the application rate in terms of lb a.i. to be applied to 100 lb seed, maximum seeding 

rates (lb seed to be planted per acre) would provide maximum exposures (e.g., 2 lb a.i./100 lb 

seed planted at a rate of 100 lb seed/acre = 2 lb a.i./acre vs. 2 lb a.i./100 lb seed planted at a rate 

of 80 lb seed/acre = 1.6 lb a.i./acre). T-REX inputs and outputs are included in Appendix 1.

EECs produced by T-REX were multiplied by 0.01 to account for burying of seeds, which is required on the label. 

T-REX input determined as follows (in some cases, minimum seeding rates (lb seed/acre) were chosen to maximize 

potential exposure as labels specified application in terms of mg a.i./seed; an animal would have to eat more small seeds 

than large seeds to satisfy dietary requirements):

-The California crop profile indicates that, typically, 4-5 lb onion seed are planted per acre 

(http://www.ipmcenters.org/CropProfiles/docs/caonions.pdf). The registrant assumes that 3 lb onion seed/acre are planted 

(406,000 seeds/acre ÷ 136,000 seeds/lb). The estimated rate was obtained as follows: 0.18 lb a.i./acre ÷ 3 lb seed/acre * 5 

lb seed/acre = 0.30 lb a.i./acre. This higher rate was also modeled because it is not certain whether the 406,000 seeds/acre 

will be included on the seed bag label.

-The Alternative Field Crops Manual indicates a typical peanut seeding rate of 90,000 seeds/acre in Minnesota and 

Wisconsin (http://www.hort.purdue.edu/NEWCROP/AFCM/peanut.html). Using the registrant provided seed weight 

maximum of 1397 seeds/lb, a seeding rate of 64 lb seed/acre was calculated for input into T-REX. 

-The California crop profile indicated a seeding rate of 6 lb seed/acre for leafy vegetables

(http://www.ipmcenters.org/CropProfiles/docs/calettuce-iceberg.pdf).

-Texas A&M indicated a seeding rate of 1.5 lb seed/acre for cole crops (broccoli) 1.5 lb seed/acre (http://aggiehorticulture.tamu.edu/extension/vegetable/cropguides/broccoli.html).

-The Georgia crop profile indicated a seeding rate of 2 lb seed/acre for carrots

(http://www.ipmcenters.org/CropProfiles/docs/GAcarrots.pdf).

-The corn seeding rate of 5.45 lb seed/acre was calculated using the Alternative Field Crops Manual and the North 

Central Region crop profile (http://www.hort.purdue.edu/newcrop/afcm/popcorn.html, 

http://www.ipmcenters.org/CropProfiles/docs/us-ncr-popcorn.pdf).

No toxicity studies were submitted for terrestrial plants; therefore, potential exposures to 

terrestrial plants were not quantified. Terrestrial exposure concentrations were not estimated for 

the CGA-322704 degradate (clothianidin) because it is not expected to pose additional toxicity 

concerns (see Section 3.3 and 4 of DP357206 (May 18, 2009) for additional information) at the 

amount and degradation pathway that it is formed. 

3.2. Aquatic Exposures

The Tier II aquatic assessment was performed using PRZM (v3.12.2)/EXAMS (v. 2.98.04.06) 

modeling with standard pond scenario. Detailed description of these models can be found in the 

previous assessment (DP357206, May 18, 2009).

3.2.1 Exposure Estimates for the Parent Compound

The PRZM/EXAMS input parameters for thiamethoxam are shown in Table 4. Inputs are 

equivalent to those used in previous assessments (DP357206, May 18, 2009). Results of the

3.2.2 Exposure Estimates for the Degradate CGA-322704 (Clothianidin)

The PRZM/EXAMS input parameters for CGA-322704 (clothianidin) are shown in Table 6. 

Inputs are equivalent to inputs used in previous assessments (D357206). Results of the 

PRZM/EXAMS modeling exercises are in Table 7. Clothianidin application rates were 

calculated using the following equation: Application rate of clothianidin = (thiamethoxam application rate) x (0.132, the maximum conversion rate 

from the degradation of thiamethoxam to clothianidin in the field dissipation studies) x (0.86, the molecular 

weight ratio of clothianidin to thiamethoxam)

*Value used for risk quantification.

Two additional studies have been submitted and reviewed since completion of the most recent 

previous assessment. A honey bee foliar residue toxicity study, which was classified as 

supplemental, has been reviewed (OPPTS 850.3030, MRID 447275-01). Residues were not 

quantified in foliage from any treatment level, and control foliage was only aged for 24 hours. 

Mortality at the highest application rate ranged from 80 to 89% between 24- and 72-hour residue 

age periods, never approaching the control mortality (1%); therefore, residue times to produce 

significant mortality useful for risk assessment (i.e., RT25 values) could not be extrapolated from 

these data. Qualitatively, these data show that residues of CGA-293343 (thiamethoxam) from 

foliage exposed to 0.004 lb a.i./acre did not result in significant mortality (<1 to 2%) of bees 

exposed to residues 24 to 72 hours after application, while significant mortality (89 to 80%) 

occurred for bees exposed to foliar residues applied at 0.088 lb a.i./acre. Although the decrease 

from 89 to 80% was not statistically significant, these data follow a suggestive pattern of 

decreasing toxicity with increasing residue age. 

A red swamp crayfish (Procambarus clarkii) study (OPPTS 850.1010, MRID 475581-06) has 

also been reviewed since the most recent previous assessment was conducted. Based on death 

and immobilization, the EC50 was 2.3 mg a.i./L. The lack of a linear dose-dependent response in 

this study precluded a reliable statistical estimation of a 96-hour LC50 with narrow confidence 
15

limits, but there were clear effects on mortality, ranging from 20-50% between the 1.3 and 11 mg 

a.i./L treatment levels; there was 50% mortality at the 2.6 mg a.i./L level. The visually 

determined LC50 was 2.3-2.6 mg a.i./L, categorizing thiamethoxam as moderately toxic to red 

swamp crayfish on an acute toxicity basis. Although the LC50 approximates the EC50, the EC50 is 

a more appropriate estimate of toxicity because of the lack of a discernible difference between 

the immobilization and death endpoints. The NOAEC was 0.65 mg a.i./L. The study is classified 

as supplemental as red swamp crayfish is not a test species indicated for use in the OPPTS 

850.1010 guideline. However, the data produced are scientifically sound and provide valuable 

information for certain use patterns (i.e., rice).

4.2. Toxicity Data for the Degradate CGA-322704 (Clothianidin)

A summary of the most sensitive definitive toxicity data for CGA-322704 (clothianidin) used to 

calculate RQs is in Table 9. Terrestrial animal toxicity data are not included because clothianidin 

has demonstrated similar or less toxicity in terrestrial organisms, including in honey bees, as 

compared to thiamethoxam. Additional information, including qualitative, non-definitive, or 

endpoints less sensitive than the parent compound, can be found in EFED’s 2005 Ecological 

Risk Assessment Document (U.S. EPA, 2005b, DP 313414).

4.3. Incidents

EFED maintains an incident database system called the Ecological Incident Information System 

(EIIS) to track and evaluate accidental kills associated with pesticide use. Based on the 

information contained in the incident report, the likelihood of a particular pesticide causing the 

incident is classified as highly probable, probable, possible, or unlikely. If there are incidents, the

information will be reviewed and considered in conjunction with the degree to which the LOCs

were exceeded, information on sales, local use practices, and monitored levels in the 
16

environment to determine whether the predicted effect based on labeled use of the product is 

likely to occur or not.

A search of the EIIS database on May 17, 2010 did not identify any adverse ecological incidents 

involving thiamethoxam. Although incident reporting is required under FIFRA Section 6(a)(2), 

the absence of reports in EIIS does not indicate that the chemical has no effects on wildlife; 

rather, it is possible that incidents have gone unreported. A search of the EIIS database on May 

15, 2009 for incidents involving other neonicotinoids, including clothianidin, imidacloprid, and 

dinotefuran, identified several incidents. These incidents involved large numbers of bees as well 

as birds, plants, crayfish, and fish and are currently under review.

Several incidents involving bee kills with other neonicotinoid insecticides in Europe have 

been reported. For example, a bee kill incident in Germany in May 2008 was likely caused 

by use of clothianidin as a seed treatment for corn1

5. Ecological Risks Summary

. A seed sticker was not used for the dust 

treatment, and seeds were planted using upward rather than downward venting equipment, 

which caused clothianidin dust particles to drift. In addition, heavy rain caused the corn seed 

to be planted later than normal when neighboring canola fields were already in bloom. 

Similar incidents have occurred in France, Italy, and Slovenia, causing the need for

regulatory action. A thorough review of all incidents is currently underway. 

5.1. Potential Risks of Thiamethoxam Exposure to Terrestrial Organisms

This assessment assumes that birds and mammals consume 100% of their diet as treated seeds, 

and 1% of seeds are available to be consumed as labels specify incorporation of treated seed to a 

depth of at least one inch. 

5.1.1. Birds

Thiamethoxam is classified as practically non-toxic to birds on a dietary basis and slightly toxic 

on an acute oral dose basis. Risk quotients were not calculated to estimate risks to birds on a 

dietary basis because no lethal effects were observed at the limit concentration for avian dietary 

toxicity studies. Dose-based acute and chronic RQs for birds are shown in Table 10. 

For small birds, all three acute LOCs were exceeded for birds consuming treated dry bulb onion, 

brassica (cole) leafy vegetable, and carrot seed using method 1 (mg a.i./kg-bw/day/LD50). The 

acute restricted use LOC and acute listed species LOC were exceeded for small birds consuming 

treated corn and leafy vegetable seeds using method 1 (mg a.i./kg-bw/day/LD50). Using method 2 

(mg a.i./ft2/(LD50*bw), none of the RQs exceeded any of the LOCs. Chronic LOC exceedances 

were observed for corn, dry bulb onions, leafy vegetables, brassica (cole) leafy vegetables, and 

carrots. RQs ranged from 0.04 to 4.89. The peanut seed treatment did not produce chronic LOC 

exceedances. Chronic effects observed at the LOAEC for birds included weight loss in parental 

males for mallards (LOAEC = 900 mg/kg-diet) and reduced egg size for bobwhite quails 

(LOAEC > 900 mg/kg-diet).

5.1.2. Mammals

Thiamethoxam is classified as slightly toxic to mammals on an acute oral basis. None of the

acute RQs exceeded concern levels (Table 10). The chronic LOC is exceeded for small 

mammals consuming treated corn, dry bulb onion, leafy vegetable, brassica (cole) leafy 

vegetables, and carrot seed. RQs ranged from 0.06 to 7.33. The peanut seed treatment did not 

produce chronic LOC exceedances. Chronic effects observed at the LOAEL (30 mg/kg-bw/day) 

for mammals included increased incidence and severity of tubular atrophy in the testes of male 

rats.

5.1.3. Terrestrial Plants

Data were not submitted to assess the toxicity of thiamethoxam to terrestrial plants. Therefore, 

risks to terrestrial and semi-aquatic plants are presumed. 

5.1.4. Terrestrial Invertebrates

Currently, EFED does not quantify potential risks of pesticides to non-listed terrestrial non-target 

arthropods. However, based on the data submitted on honey bee toxicity, thiamethoxam is highly 

toxic to honey bees (LD50 = 0.024 and 0.005 μg/bee on an acute contact and oral exposure basis, 

respectively). It is possible that terrestrial invertebrates, especially pollinators such as bees, 

would be exposed to thiamethoxam, as it is a systemic, persistent insecticide. Uncertainties 

remain regarding the effects to non-target arthropods through exposure to translocated residues

(the parent thiamethoxam and the degradate clothianidin) in nectar and pollen. While the degree 

to which thiamethoxam is metabolized to clothianidin within the plant is unknown and may vary 
18

by crop, clothianidin has similar toxicity to thiamethoxam, which is demonstrated by acute 

contact and oral honey bee data. Pollinator field study data have been requested to evaluate 

potential effects through these possible routes of exposure; some data have been received and are 

currently under review. In addition, residue data in the open literature has recently been 

identified as well as data produced for the California Department of Pesticide Regulation. These 

data will be reviewed and included in future assessments as appropriate. 

Due to the incidents associated with other neonicotinoids in Europe (see Section 4.3) and 

considering the available data, potential for risks to pollinators and other non-target beneficial 

arthropods resulting from the proposed and existing applications of thiamethoxam exists. These 

risks were not quantified. A practice to mitigate risks to non-target arthropods, which may 

provide commercially important pollination and other ecological services, includes, but is not 

limited to, establishing and maintaining alternative untreated habitat and forage in areas 

surrounding agricultural fields2

A summary of risk quotients based on acute exposure of freshwater midge and estuarine/marine 

mysid to thiamethoxam is presented in Table 11, below. With risk quotients ranging from 0.01 –

0.33 for freshwater midge, the acute listed species and restricted use LOCs are exceeded for

freshwater invertebrates for most of the scenarios. Only four scenarios assessed (two for dry bulb 

onions, one for peanuts, and one for corn) did not produce RQs that exceeded LOCs. Every 

assessed use exceeded the restricted use and listed species LOC except for peanuts, which did 

not result in any LOC exceedances. RQs for estuarine/marine species were <0.01; acute risks to 

.

5.2. Potential Risks of Thiamethoxam Exposure to Aquatic Organisms

5.2.1. Fish

A definitive LC50 was not established for thiamethoxam for both freshwater and estuarine/marine 

fish. As a result, acute risk quotients were not calculated for fish. However, a comparison of the 

established NOAEC values of 100,000 μg/L for rainbow trout, 114,000 μg/L for bluegill sunfish,

and 111,000 μg/L for sheepshead minnow from acute exposure studies with the estimated peak 

surface water concentrations of thiamethoxam, which ranged from 0.45 to 11.47 μg/L, suggest 

that estimated peak exposure concentrations are well below the concentrations shown to result in 

no adverse effects to both freshwater and estuarine/marine fish. Therefore, potential risks do not 

trigger concerns at this time for either freshwater or estuarine/marine fish on the acute exposure 

basis. 

Although no chronic effects on reproduction were noted, a comparison of the highest dose tested 

in the study (20,000 μg/L) for freshwater rainbow trout with the 60-day average EECs (0.27 to 

7.58 μg/L) indicated that exposure estimates are well below concern levels for potential chronic 

risks to freshwater fish. Although chronic data were not submitted for estuarine/marine fish, 

chronic risks would similarly fall below concern levels as acute freshwater and estuarine/marine 

fish data do not suggest a difference in sensitivity across media. 

5.2.2 Aquatic Invertebrates

 2 http://www.xerces.org/pollinator-conservation-agriculture/
19

estuarine/marine invertebrates did not exceed LOCs. Chronic risks to aquatic invertebrates based 

on exposure to thiamethoxam do not exceed LOCs based on the NOAEC value of 50,000 μg/L

and peak exposure concentrations of 11.47 μg/L and less.

Based on the acute to chronic ratio (ACR)-derived midge NOAEC (NOAEC <16.51 μg/L, see 

Section 4.1.2 of the previous assessment; DP357206, May 18, 2009), it is possible for chronic

LOCs to be exceeded because chronic EECs ranged from 0.39 to 9.85 μg/L. Chronic risk to 

freshwater invertebrates cannot be ruled out until acceptable chronic midge data (satisfied by the 

850.1735 guideline) providing a definitive NOAEC is submitted to the Agency. Since the ACRderived midge NOAEC is non-definitive (<16.51 μg/L), chronic risks to freshwater invertebrates 

were assumed to exceed LOCs for all uses. Additionally, either the chronic midge data or a 

chronic estuarine/marine study is needed to evaluate risks to estuarine/marine invertebrates. In 

the absence of this data, chronic risks to estuarine/marine invertebrates were assumed for listed 

species.

5.2.3. Aquatic Plants

Potential risks to aquatic plants from the proposed new uses of thiamethoxam were evaluated 

using the toxicity data for a vascular plant (Lemna gibba) and a non-vascular plant 

(Pseudokirchneriella subcapitata). Toxicity values for these two aquatic plants were nondefinitive (> than the highest concentration tested); therefore, risks for the above species were 
21

ascertained based on the comparisons of estimated peak thiamethoxam concentrations in surface 

water and the non-definitive toxicity values. The most conservative peak EEC (11.47 μg/L for 

treated leafy vegetable seed) is more than three orders of magnitude lower than the nondefinitive toxicity values for vascular (EC50 >90,000 μg/L) and non-vascular (EC50 >97,000 

μg/L) plants; therefore, risks to aquatic plants are presumably less than concern levels.

5.3. Potential Risks of Major Degradate CGA-322704 (Clothianidin) Exposure to Aquatic 

Organisms

The acute listed species LOC was exceeded for all scenarios assessed except for peanuts for 

freshwater invertebrates exposed to the degradate CGA-322704 (clothianidin) as a result of the 

proposed or registered thiamethoxam applications (Table 12). In addition, the acute restricted 

use LOC was exceeded for leafy vegetables exposed to the degradate CGA-322704

(clothianidin). The chronic LOC was not exceeded for any use.

6. Data Gaps and Uncertainties

1. Whole Sediment Acute Toxicity Test for Freshwater Invertebrates (850.1735): 

This 28-day study measures survival, growth, and emergence of Chironomus riparius that has 

been exposed to pesticide-spiked sediment and overlying water. EFED recommends that a 

request be made for this acute sediment toxicity test, which also measures chronic effects,

because thiamethoxam is very highly toxic to midge and is persistent in the environment. The 

previously submitted study on midge (MRID 447149-18) larvae exposed to thiamethoxamspiked water solution and is 48 hours in duration. Therefore, chronic risks to sediment-dwelling 

midge could not be comprehensively assessed using this study. Prior to initiation of this study, a 

protocol should be submitted to EFED for approval.

2. Field Test for Pollinators (850.3040)3

Because thiamethoxam is highly toxic to honey bees on an acute exposure basis and is a 

persistent, mobile, and systemic insecticide, pollinators have a high potential of being exposed to 

and affected by residues of thiamethoxam and its degradation products (clothianidin) in pollen 

and nectar of plants. EFED recommends that the registrant conduct field studies at maximum 

proposed label rates using crops that are attractive to bees (e.g., pears or apples) for seed 

treatment, foliar, and soil applications. These three studies should be conducted in consultation 

with EFED and should examine the exposure and effects to adults and brood. The studies should 

: 

 3 EFED acknowledges recent receipt of a pollinator field study (MRID 480533-01). This study is currently under 

review to determine if it satisfies data requirements. In addition, the California Department of Pesticide Regulation 

has requested residue monitoring data. This data, along with relevant open literature, may be used by EFED as 

appropriate.
23

measure the amount of thiamethoxam translocated to the nectar and pollen of the target crop and 

rotational crops and potential adverse effects, including sublethal effects.

3. Terrestrial Plant Toxicity, Tier I (seedling emergence) (850.4100): Testing of a typical 

end-use product (TEP) is required for all pesticides having outdoor uses at the proposed 

maximum application rate. Because thiamethoxam is an insecticide, Tier II studies are not 

required unless Tier I studies indicate a ≥ 25% effect to various growth parameters relative to the 

control. Currently, the lack of these data results in a presumption of indirect effects to all listed 

species based on potential habitat modification.

4. Terrestrial Plant Toxicity, Tier I (vegetative vigor) (850.4150): Testing of a TEP is 

required for all pesticides having outdoor uses at the proposed maximum application rate. 

Because thiamethoxam is an insecticide, Tier II studies are not required unless Tier I studies 

indicate a ≥ 25% effect to various growth parameters relative to the control. Currently, the lack 

of these data results in a presumption of indirect effects to all listed species based on potential 

habitat modification.

5. Avian Acute Oral Toxicity Test (850.2100): Data are required for one passerine species and 

either one waterfowl species or one upland game bird species for terrestrial, aquatic, forestry, 

and residential outdoor uses. The current method of calculating a weight-adjusted LD50 using 

bobwhite quail or mallard duck data may over- or under-estimate risks to passerines because 

these birds may metabolize the chemical differently. Because the 850.2100 guideline has not yet 

been finalized, protocols for the study of passerine species should be submitted to EPA for 

approval prior to study initiation.

Additionally, the following uncertainties were identified for this risk assessment:

• Studies are not available to document the toxic effects of thiamethoxam on chronic 

exposure basis to both estuarine/marine fish and invertebrates. However, the acute studies 

for both freshwater fish and estuarine/marine fish do not suggest a great difference in 

toxicity across media; effects are expected to be similar for both freshwater and 

estuarine/marine fish. Currently, risks are assumed to estuarine/marine invertebrates on a 

chronic basis; if a definitive chronic freshwater midge study (850.1735; see data gap #1) 

is received, the acute-to-chronic ratio method can also be used to extrapolate risks to 

estuarine/marine invertebrates as follows: 

Chronic toxicitymysid shrimp= Acute toxicitymysid shrimp x Chronic toxicitymidge / Acute 

toxicitymidge. 

However, the acute-to-chronic ratio adds uncertainty to the risk estimation because the 

actual toxicity value and the resulting risk quotients may be over- or under-estimated. 

• This risk assessment only considered the most sensitive of the species evaluated in the 

registrant-submitted studies. The position of the tested species relative to the distribution 

of all species’ sensitivities to thiamethoxam is unknown. Extrapolating the risk 

conclusions from the most sensitive tested species to non-tested species may either 

underestimate or overestimate the potential risks to those species. The acute toxicity of 

thiamethoxam to midge (EC50 = 35 μg/L) and water flea (EC50 >106,000 μg/L) highlights 

this point.

7. Listed Species

This assessment identified potential direct effects to terrestrial and aquatic invertebrates, birds 

(surrogate for reptiles and terrestrial amphibians), and mammals, Also, potential risks to listed 

terrestrial plants were assumed to exceed concern levels due to the absence of toxicity data for 

terrestrial plants. LOC exceedances for listed species are summarized in Table 14.

The Agency’s Level of Concern was exceeded for freshwater invertebrates (acute), birds (acute and chronic), and 

mammals (chronic); risks to terrestrial plants and chronic risks to all aquatic invertebrates were assumed due to the 

absence of data, and there is potential for risks to terrestrial invertebrates even though a method for risk 

quantification is not in practice. 

2

Indirect effects to a listed species occur when its prey base is reduced or habitat is modified. Indirect effects to all 

taxa are assumed due to lack of terrestrial plant data. 

LOCATES was used to determine co-occurrence of listed species and the proposed uses of

thiamethoxam application to dry bulb onion and peanut seed and the registered uses of 

thiamethoxam application to carrot, brassica (cole) leafy vegetable, corn, and leafy vegetable 

seed. These species are included in Appendix 3.
