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.
