The attached memorandum presents the drinking water assessment in response to a Syngenta request 

to amend the label of Fusilade® DX Herbicide (EPA Reg No. 100-1070) to allow for the use of the active 

ingredient fluazifop-p-butyl (PC Code 122809) on five new crops: bananas, plantains, citrus, grapes and 

sugar beets. A drinking water assessment was completed by EFED for fluazifop-p-butyl in 

August 2008. In that assessment EFED modeled surface and groundwater concentrations of the 

herbicide based upon acid equivalents. The same approach was used in this current assessment.

Questions related to this assessment can be directed to William Eckel, Ph.D., (703) 305-6451

Drinking Water Assessment for the Section 3 Registration of 

Fluazifop-p-butyl For Use on Bananas, Plantains, Citrus, Grapes and Sugar Beets

May 25, 2010

Summary

This document reports the results of a drinking water exposure assessment conducted to support the 

human health risk assessment for the Section 3 registration of fluazifop-p-butyl (butyl (2R)-2-[4-[[5-

(trifluoromethyl)-2-pyridinyl]oxy]phenoxy]propanoate; CAS Number 79241-46-6), for use as a postemergent aryloxyphenoxypropionic herbicide to control perennial and annual grass weeds on bananas, 

plantains, citrus, grapes, and sugar beets pre-bloom and post-bloom (Strader 2009). Major degradates 

observed in environmental fate studies included

2R)-2-[4-[[5-(trifluoromethyl)-2-pyridinyl]oxy]phenoxy]propanoic acid (fluazifop-p-acid), 2-hydroxy5-trifluoromethylpyridine (degradate X), and 2-(4-hydroxyphenoxy)-5-trifluoromethylpyridine 

(degradate IV).

A drinking water assessment was completed by EFED for fluazifop-p-butyl in August 20081. In that 

assessment EFED estimated the environmental exposures to fluazifop-p-acid because the parent rapidly

degrades in aerobic environments to its acid form, and therefore, the form most likely to be present in

drinking water. In the current assessment environmental exposures will again be estimated based on the 

presence of the parent-acid.

In both the 2008 and current assessment the potential human exposure to fluazifop-acid in drinking 

water were evaluated using modeling because of the absence of targeted monitoring data for previous 

uses and no monitoring data for the proposed new uses. Estimated exposure concentrations (EECs) in 

ground water were modeled using Tier I SCIGROW (version 2.3, dated July 29, 2003) and surface water 

EECs were modeled using Tier II PRZM (Pesticide Root Zone Model; vers. 3.12.2, May 12, 2005) and 

EXAMS (EXposure Analysis Modeling System; Vers. 2.98.04.06).

The results of the 2008 assessment for aerial applications indicated that the highest surface water 

EECs reported for peak, 1 in 10 year average, and the 30 year average as estimated by PRZM/EXAMS 

for all crop use scenarios were 23.9 ppb, 5.1 ppb, and 3.6 ppb, respectively. For ground applications the 

highest EECs for peak, 1 in 10 year average, and the 30 year average were 22.8 ppb, 4.9 ppb, and 3.1 

ppb, respectively. For ground water the SCIGROW estimated the peak, 1 in 10 year average, and the 30 

year average concentrations to be 0.59 ppb.

The results of this current assessment are somewhat higher. For aerial applications the highest 

surface water EECs reported for peak, 1 in 10 year average, and the 30 year average as estimated by 

PRZM/EXAMS for all crop use scenarios were 33.4, 6.6 ppb, and 4.4 ppb, respectively. For ground 

applications the highest EECs for peak, 1 in 10 year average, and the 30 year average were 32.1 ppb, 5.8 

ppb, and 3.1 ppb, respectively. SCI-GROW estimated the concentration of fluazifop-acid in shallow 

ground water sources to be 1.56 ppb. The difference between the 2008 and current assessment results

can be attributed to a proposed increase in the maximum number of allowable applications (i.e., 3 vs. 2), 

and differences in crop use scenarios used in the two assessments.

Environmental Fate and Transport Characterization

The fate and transport characteristics of fluazifop-butyl, its acids and degradates have been 

extensively detailed in EFED’s August 2008 report. In summary, fluazifop-butyl (PC Code 122805) is 

the racemic mixture (e.g., consists of equal amounts of the R and S enantiomers) of butyl-2-{4-[5-

(trifluoromethyl)-2-pyridyloxy]phenoxy}propionate. Fluazifop-p-butyl (PC Code 122809) is the R 

enantiomer and is more herbicidally active than the S enantiomer (Tu et al. 2001). Both transform 

primarily via microbial mediated hydrolysis in moist soil and sediments to the fluazifop-acid which can 

also exist in the R or S form (MRID 162455; 87493, 92067033, 87492, 92067032, 46190602, 

46190605). The chemical structures and names are shown in Appendix A, Table A.1. Exposure is 

primarily expected to be to fluazifop-acid, either in the R or S form (see discussion in Appendix A of 

EFED’s 2008 assessment).

Fluazifop-acid (pKa ~ 3) will primarily be present in the anionic form at environmental pH (Kah et 

al. 2007). Primary metabolism pathways are aerobic and anaerobic degradation. Three degradates were 

measured at greater than ten percent of applied or total radioactivity recovered: fluazifop-acid, fluazifopp-acid, and 2-hydroxy-5-trifluoromethylpyridine.

Exposure Modeling

Modeling was used to estimate the drinking water exposure for use in the dietary risk assessment of 

fluazifop-p-butyl. Estimated exposure concentrations represent exposure to fluazifop-acid, with 

assumptions that fluazifop-acid may be present in the R or S form or as a mixture of the enantiomers. 

The following is a description of the models used, the selection of the model input parameters, and the 

modeling results.

Surface Water Modeling

Estimated drinking water concentrations (EDWCs) in surface water were estimated using the 

Environmental Fate and Effects Division’s (EFED’s) Tier II aquatic models: PRZM (Pesticide Root 

Zone Model; vers. 3.12.2, May 12, 2005) and EXAMS (EXposure Analysis Modeling System; Vers. 

2.98.04.06). Calculations were carried out with the linkage program shell – PE5.0 (November 15, 2006)

- using standard scenarios developed by EFED.

PRZM simulates pesticide fate and transport as a result of leaching, direct spray drift, runoff, and 

erosion from an agricultural field, and EXAMS estimates environmental fate and transport of pesticides 

in a surface water body for a 30-year period. The combined model is designed to estimate pesticide 

concentrations assuming runoff from the edge of the treated field empties directly into the receiving 

body (in this case, the index reservoir). As such, it provides high-end estimates of the pesticide 

concentrations. The location of the field is specific to the crop being simulated using site-specific 

information on the soils, weather, cropping, and management factors associated with the scenario. The 

crop/location scenario is intended to represent a high-end exposure site on which the crop is normally

grown. Based on historical rainfall patterns, the receiving water body receives multiple runoff events 
4

during the years simulated. Weather and agricultural practices are simulated for 30 years so that the 10-

year exceedance probability at the site can be estimated. The simulation was generated using 30 years of 

meteorological data, encompassing the years from 1961 to 1990. Additional information on these 

models can be found at: http://www.epa.gov/oppefed1/models/water/index.htm. For drinking water 

exposure assessments, the Index Reservoir (IR) scenario is used in lieu of the standard pond scenario. It 

is used in a manner similar to that which the standard pond is used in ecological exposure assessments, 

except that flow rates have been modified to reflect local weather conditions. The index reservoir (IR) is 

approximately 82-m wide and 640-m long, with an area of 5.3 hectare (ha). The area of the entire 

watershed is 172.8 ha. Guidance for using the IR is located at: 

http://www.epa.gov/pesticides/trac/science/. 

Proposed application information from the label used in modeling for all proposed uses is shown in 

Table 1 along with the scenarios used to represent exposure from each use. Foliar applications via 

ground spray and aerial spray were simulated using the recommended application rate and the maximum 

application rate combined with the maximum possible number of applications for that rate. The 

application date was assumed to be one week after the crop emergence date in the PRZM/EXAMS 

scenario. Other input parameter values used in this assessment were selected from the environmental 

fate data submitted by the registrant and in accordance with US EPA-OPP EFED water model parameter 

selection guidelines, Guidance for Selecting Input Parameters in Modeling the Environmental Fate and 

Transport of Pesticides, Version II, February 28, 2002 and Guidance for Use of the Index Reservoir in 

Drinking Water Exposure Assessments, November 16, 1999. Input values used for modeling are 

presented in Table 2 and results in Table 3. Appendix B contains the model output files and tables 

showing the data used to calculate input values.

g/mole fluazifop-butyl = kg acid equivalents/ha. The application rates were converted to acid equivalents for use in 

PRZM/EXAMS because fluazifop-butyl degrades rapidly and exposure is modeled for fluazifop-acid.

4 Time interval between pesticide applications as described in Fluazifop-p-Butyl Tolerance Petition Sect 408(d)(2)(A)(iii).

5There is no crop scenario in PRZM/EXAMS for bananas/plantains. However, because of similarities in soil characteristics 

the Puerto Rico Coffee (PRCoffeeSTD) scenario was used in the modeling.

than KOC, so the KF values were used for input values.

KOC values; however, when sorption is not well 

predicted by the KOC the lowest non sand Kd value is 

used.

Groundwater Modeling 

The regression model SCI-GROW2 (v. 2.3) was used to estimate the concentration of fluazifop-acid in 

ground water. SCI-GROW estimated the concentration of fluazifop-acid in shallow ground water 

sources to be 1.56 ppb. Input parameters for SCI-GROW are presented in Table .

SCI-GROW2 is a regression-based, Tier I screening model that provides a groundwater exposure value 

to be used in determining the potential risk to human health from drinking water contaminated with the 

pesticide. SCI-GROW2 estimates likely groundwater concentrations if the pesticide is used at the 

maximum allowable rate in areas where groundwater is vulnerable to contamination. Characteristics of 

such vulnerable areas include high rainfall, rapidly permeable soil, and a shallow aquifer. In most cases, 

a large majority of the use area will have groundwater that is less vulnerable to contamination than the 

areas used to derive the SCI-GROW2 estimate.

The properties of fluazifop-acid, namely high mobility and long persistence in water (minimal 

hydrolysis occurred at pH 9 according to Negre et al. 1988; MRID 46190601) and anaerobic soil (halflife 1 to 3 years, MRIDs 87493, 92067032, and 92067033) indicate that it might persist from year to 
8

year in the subsurface, and move with flowing ground water. Thus, the screening value of 1.56 ppb may

not adequately describe the expected behavior of fluazifop-acid.

Monitoring

According to EFED’s August 2008 assessment, fluazifop-butyl has been detected in both river water 

and ground water samples at concentrations less than 0.2 parts per billion (ppb). This indicates that 

there is a potential for fluazifop-butyl to reach surface and ground waters; however, it is not expected to 

persist as fluazifop-butyl. This is supported by monitoring results that only detected fluazifop-butyl in 

the time frame that it was expected to be used (Martinez et al. 2000). Fluazifop-acid was not detected in 

a non-targeted ground water monitoring study completed in Germany (MRID 40439401); however, the 

fluazifop-butyl results indicate that fluazifop-acid also has the potential to be found in groundwater 

samples as it is the primary degradate of fluazifop-butyl and it is more stable than the parent. The 

limited monitoring results available are summarized below. 

 Fluazifop-butyl was detected in 27% (five out of 18) samples of river water in the Guarena and 

Almar river basins in Spain and 13% (three of twenty three) samples of ground water (Martinez et 

al. 2000). All detections of fluazifop-butyl occurred in the sampling period when fluazifop-butyl

was expected to be used on lentils and chickpeas in the area sampled. When the sampling time was 

targeted to when fluazifop-butyl was used, it was detected in 56% of (five out of nine) river water 

samples at the detection limit to 0.20 μg/L and 20% (three of 15) of ground water samples at the 

detection limit to 0.18 μg/L.

3

 

 In a regional groundwater monitoring program conducted in Northern Ireland, fluazifop-p-butyl 

was detected in one of 82 ground water samples at a concentration of 0.0041 μg/L (Scott and 

McConvey 2005). 

 A groundwater survey was completed in West Germany that analyzed 605 water samples from 95 

raw water wells (MRID 40439401). No residues of fluazifop-acid were found (limit of detection 

was 0.00008 mg/L).

 

3

Fluazifop-butyl usage was expected to occur between April and June and the samples collected between June and 

September (Martinez et al. 2000). Samples collected between October and December did not detect residues of fluazifopbutyl.
9

 Fluazifop-butyl was reportedly detected in three samples from community drinking water supplies 

in McFarland and Kern County, California at concentrations of 0.06, 0.16, and 0.17 μg/L 

(http://www.fluoridealert.org/pesticides/fluazifop-p-butyl.page.htm). No other information was 

found regarding these reported concentrations and no information is available on the reliability of 

the data. 

 Fluazifop-butyl was listed in the USEPA STORET database and was reported as not detected in 

553 ground water samples collected between 1991 and 2002 by the Arizona Department of 

Environmental Quality (USEPA STORETv2.0 Database; available at 

http://www.epa.gov/storet/dw_home.html).

Department of Pesticide Regulation (DPR) Surface Water Database (available at 

http://www.cdpr.ca.gov/docs/emon/surfwtr/surfdata.htm) were searched for any monitoring information 

on fluazifop-butyl and fluazifop-acid. No monitoring information was found.
