Comments on proposed mitigation are due July 31, 2024
Captan is a fungicide which many peach growers use to control diseases in the orchard from bloom through the early preharvest period. The EPA conducts a periodic review of exiting pesticides registered every 15 years.
To view the amended proposed interim registration review in its entirety, see Docket No. EPA-HQ-OPP-2013-0296 at www.regulations.gov. For instruction on how to submit comments, visit https://www.regulations.gov/document/EPA-HQ-OPP-2013-0296-0335.
Summary of Mitigation for Orchard Crops:
*Prohibit aerial application of DF/WDG and WP formulations;
*Reduce maximum application rate for apples, peaches, and nectarines, from 4 to 3 lbs ai/A;
*Reduce maximum application rate for cherries from 3.16 to 3.0 lbs ai/A;
*Require PF50 respirator, single layer protective clothing, 85 and chemical-resistant gloves for handlers mixing/loading DF/WDG and WP formulations for airblast application;
*Require enclosed cabs and single layer protective clothing for airblast applicators;
*Require enclosed cabs and single layer protective clothing for groundboom applicators treating orchard crops or PF10 respirator, chemical-resistant gloves, and single layer protective clothing; and
*Limit application with mechanically pressurized handgun to spot treatment of areas missed with other application equipment, such as application to row ends.
*There are no proposed changes to the current REIs on captan product labels for orchard crops.
