Objective

The purpose of the meeting was for members of EPA’s Captan Registration Review Team to meet with

the captan registrants and USDA to discuss the registration review schedule , process, and data

requirements, as well as the following aspects of the captan registration review:

Clarification of u se p atterns , especially for turf and ornamentals, greenhouse bench treatment, and

antimicrobial uses

,

Discussion of l abel amen dments to comply with the terms of the 2004 Captan RED Amendment

,

Clarification of r egistrant support for antimicrobial uses , and

Development of a master label and t iming of label amendments.

Discussion

Presentation by Captan Task Force

. Jim Barron of the Captan Task Force walked through a set of

PowerPoint slides (attached). This presentation provided a broad overview of the history of the captan

registration, general use patterns, and available formulations. The Task Force presentation also clarified

captan use on lawn seed beds, dichondra, and use as a greenhouse bench treatment.Maximum Application Rates, Frequency, and Timing of Application

. The EPA registration review team

has requested clarification of this information for all r egistered uses of captan. During the meeting, EPA

emphasized the importance of cleaning up the captan labels and developing a master label prior to

initiation of the risk assessment phase of the captan registration review. The Agency will rely on

registr ants to pull together a master label. However, the Captan Task Force stated that with > 100 captan

end

- use products, gathering this information will be extremely difficult. The Task Force is currently

comprised of three companies: MANA, MCW, and Arysta. Although EPA looks to registrants to

develop a master label, the Agency can assist by sending a letter to all captan end

- use registrants

regarding necessary label changes or clarifications.

Meeting participants discussed the following use patterns in detail:

Characterization of Use on Turf . Meeting participants discussed use of captan on turf. EPA

mentioned that some of the turf labels are unclear regarding the turf use. The Agency reiterated

the restrictions on this use specified in the 2004 Cap tan RED amendment, stated below:

“Do not apply to residential lawns.” (RED amendment*, p. 29)

“Do not apply to turfgrass in residential sites, including homes, apartment buildings,

daycare centers, schools, playgrounds, parks, recreational areas, sports fields, or other

residential areas.” (RED amendment, p. 28)

In addition, the captan r egistran ts asked for clarification of restrictions for captan use on sod

farms.

Registrant Support of Antimicrobial Uses

. All of the captan technical labels currently allow

formulation into end

- use products for antimicrobial use s

. EPA expects to levy data requirements

for these uses in the Registration Review DCI , and would like to clarify registrant support for

antimicrobial uses of captan early in the registration review process. Registrants had some general

questions about the a ntimicrobial use.

USDA Comments

. The USDA representative mentio ned the importance of captan in fungicide resistance

management in U.S. agriculture. Captan is a multi

- site fungicide that is effective against pathogens that

have developed resistance to s everal single

- site fungicides used in a given crop (multifungicide

resistance) thereby managing resistant fungal populations

.

Follow Up Items

Clarification of m aximum a pplication r ates, f requency, and t iming of a pplicatio n for all captan

uses.

Development of a captan master label.

Label amendments to ensure compliance with the 2004 RED amendment, especially for use on

turf.
