INTRODUCTION 

The purpose of this document is to convey usage information and a broad overview of the pest 

management roles of pesticides that are beginning to undergo registration review. The 

anticipated audience consists of the team of EPA staff currently evaluating the registration status 

of captan and eventually the general public. This document builds upon the data already 

1 
provided in the usage and label use data packages that are also provided to Registration Review 

teams by BEAD. The document is based on information and data available to BEAD as of 

November 21,2012. 

Captan was registered in 1951. The Reregistration Eligibility Decision (RED) for captan was 

issued in 1999. Captan is a fungicide that belongs to group M4 of fungicide as per Fungicide 

Resistance Action Committee (FRAC, 2012). Captan is a broad-spectrum fungicide with 

protectant and some curative activity. It is used on a wide range of agricultural and horticultural 

crops in temperate, sub-tropical and tropical climates in open fields and glasshouses. 

HISTORY OF BEAD ASSESSMENTS FOR CAPT AN 

No BEAD assessments were found in BEAD's Official Records. 

SECTION 18 EMERGENCY REQUEST HISTORY 

There have been no requests for emergency uses of this chemical on any crop to control fungal 

pests under FIFRA Section 18. Emergency exemption requests indicate a valuable use for a 

chemical due to a lack of effective control methods on specific crop against specific pests. 

However, the lack of emergency requests does not imply a lack of value in registered uses. 

COMMON FORMULATIONS AND APPLICATION METHODS 

Captan is formulated as dust, granular, wettable powder, water dispersible granules, flowable 

concentrate, soluble concentrate and water soluble packaging. Captan is applied by broadcast, 

chemigation, dusting, drip treatment to soil and as spot applications. Captan is also used as a seed 

treatment. 

USE SITES 

Agricultural Use Sites 

Captan is a fungicide registered for use on caneberries, grapes, strawberries, nut crops, pome 

fruits, stone fruits, cucurbits, fruiting vegetables, leafy and stem vegetables, root crop vegetables, 

seed and pod vegetables, forage grasses, forage legumes, grain crops, ginseng, beets, com, 

cotton, peanuts, soybeans and rapeseed. 

Non-Agricultural Use Sites 

Captan is a fungicide registered for use on ornamental herbaceous plants, ornamental lawns and 

turf, ornamental woody shrubs and vines, ornamental trees, wood structure protection and 

greenhouse soils. 

USAGE 

Agricultural Usage 

Based on private market usage data from 2001-2011, usage averaged approximately 2.8 million 

pounds active ingredient (a.i.) for 1.5 million acres treated. The average a.i. rate over this time 

period was 1.9 pounds a.i./acre. More recently, in the 2009-2011 timeframe the average a.i. rate 

was lower at 1.7 pounds a.i./acre. Figure 1 presents captan usage in pounds a.i. over the 2001-

2011 timeframe. Figure 2 presents total area treated in acres over the 2001-2011 timeframe.

. Table 1 shows a comparison of crops with the highest use of captan between the two time frames 

of2001-2006 and 2007-2011. Apples, strawberries, peaches, and almonds were the top crops in 

both timeframes, with apples accounting for over 50 percent of all use in both time periods. The 

average a.i. rate for apples and almonds increased between the 2001-2006 and the 2007-2011 

timeframes, while the average ai. rate for strawberries and peaches decreased between the two 

timeframes. For apples, the rate increased from 1.8 pounds aiJacre in 2001-2006 to 

approximately 2.0 pounds/acre in the 2007-2011 timeframe, and for almonds the rate increased 

from 2.9 pounds ai.lacre to 3.15 pounds/acre.

Table 2 shows a comparison of States with the highest use of captan between the two time 

frames of2001-2006 and 2007-2011. California, New York, Michigan and Pennsylvania were 

the States with the most use in both timeframes, even though New York was the State with the 

most use in the latter time frame when compared to the earlier period where California was the 

top State. These four States accounted for approximately 70 percent of all use in both time 

periods.

Agricultural Usage by Crop Reporting District 

Another measure of usage is the use intensity. In this analysis, the use intensity is expressed as 

the pounds a.i. applied per 1000 acres of land in fanns. This differs from the application rate, 

which is expressed as the pounds ai. applied per treated area. The average application rate of 

1. 7 lb per acre implies a rate of 1700 lb a.i. per 1000 treated acres. The maximwn use intensity 

observed is about 230 lb ai. per 1000 acres of fannland. Figure 3 spatially represents captan 

usage by crop reporting district for 2006-2010. The highest use intensity is in the Northeast, 

especially New York and Michigan.

This is a map of agricultural pesticide usage at the Crop Reporting District (CRD) level prepared by BEAD 

for use in the Environmental Fate and Effects Division documents. These maps are used to help visualize 

where the pesticide being considered is most likely to be used and can be helpful in scenario selection and 

placing the exposure assessment in context. CRDs are boundaries created by USDA NASS which are 

aggregates of counties (USDA, 2010). Pesticide usage is displayed as average pounds (for the years 2006-

2010) per 1,000 acres of farmland in a CRD to normalize for the variation in farmland between CRDs. 

Farmland acreage was obtained from USDA (2007). Fannland or "land in farms" is defined as follows: 

The acreage designated as "land in farms" consists primarily of agricultural land 

used for crops, pasture, or grazing. It also includes woodland and wasteland not 

actually under cultivation or used for pasture or grazing, provided it was part of 

the farm. operator's total operation. Large acreages of woodland or wasteland 

5 
held for nonagricultural purposes were deleted fiom individual reports during 

the edit process. Land iil farms includes CRP, WRP, FWP, and CREP acres. 

Land in fanns is an operating unit concept and includes land owned and 

operated as well as land rented fiom others. Land used rent free was reported as 

land rented fiom others. All grazing land. except land used under government 

permits on a per-head basis, was included as "land in farms" provided it was 

part of a farm or ranch. Land under the exclusive use of a grazing association 

was reported by the grazing association and included as land in farms. All land 

in American Indian reservations used for growing crops, grazing livestock. or 

the potential of grazing livestock was included as land in farms. Land in 

reservations not reported by reservation, individual American Indians or nonNative Americans was reported in the name of the cooperative group that used 

the land. In many instances, an entire American Indian reservation was reported 

as one farm (2007 Census of Agriculture, USDA). 

Usage is based on private market surveys of pesticide use in agriculture (Proprietary Data, 2006-2010). The 

survey data are limited to the states that represent the top 80-900/0 of acreage for the individual crops, 

therefore, use may be occurring in regions outside the scope of the survey. CRDs showing no usage of 

pesticides may be due to either the lack of pesticide use in the region or non-participation in the agricultural 

surveys. In addition, across the years, there may be variations in the specific crops included in the CRD 

survey. This may result in a lower annual average for the CRD. 

This map displays ratio data (i.e., average pounds per 1,000 acres of farmland) summarized at a very highlevel. Readers are strongly cautioned against trying to over interpret the map without examination of the 

underlying data. The underlying data may explain some of the many reasons that a Crop Reporting District 

may have a high value for a particular active ingredient such as significant acreage (compared with the CRD 

as a whole) of a crop or crops with a high application rate and frequency of application. 

The reader should pay particular attention to .the figure legends and realize that a map prepared for a 

particular chemical is not directly comparable to a map prepared for a different chemical. Scale and units of 

measurement do matter and may be different between maps.

Non-Agricultural Usage 

In tenns of non-agricultural usage, reported data are available only for nursery/greenhouses for 2002, 

2004, and 2006, consumer fungicide for 2003, landscape for 2004, golf courses for 2006, and lawn 

care operators for 2006 as shown in Table 3 below. The reported data shows that consumer use 

accounts for the majority of non-agricultural usage. It is important to note that these data are dated 

but are presented in this document for reference.
