2013 Annual Report

1a. Objectives (from AD-416):
Obtain performance data and/or residue samples or analyze crop samples to support the registration of minor-use pesticides for food, ornamental and specialty crops.

1b. Approach (from AD-416):
Minor-use pesticides alone or in combination with cultural and mechanical methods will be evaluated under field, orchard, nursery and greenhouse conditions through determination of pest control by species, crop injury and crop yield. Plant samples will be collected for determination of pesticide residues according to protocols and good laboratory practices specified by the National IR-4 Headquarters.

3. Progress Report:
ARS Food-Use Field Director completed 23 residue trials in 3 locations. The project was conducted at remote sites at Fremont, OH and Celeryville and at the Wooster station of the Ohio Agricultural Research and Development Center (OARDC). Residue samples were collected and sent to pre-determined residue laboratories for analyses under quality assurance using Good Laboratory Practices as dictated by Environmental Protection Agency analytical guidelines and the IR-4 headquarters at Rutgers University. Two studies were reported in Plant Disease Management (APS). Ornamental studies were also performed on 12 species at the OARDC site and reported to IR-4 Headquarters. Experimental results were conveyed to growers at OFA and Ohio Nursery and Landscape Association Trade Shows.
