2013 Annual Report

1a. Objectives (from AD-416):
Conduct trials necessary for registration of modern herbicides for safe use in minor and specialty crops.

1b. Approach (from AD-416):
Based on priority projects established by IR-4 and USDA, evaluate herbicides alone or in combination with other management methods to support registration on minor and specialty crops. Data will include determination of weed control efficacy and/or collection of plant samples for chemical residue determination.

3. Progress Report:
In the last year, residue experiments were conducted on penoxsulam+oxyfluorfen, clomazone, QGU42, fluopicolide, quinoxyfen, V-10208, BYI 02960, fenpyroximate, pendimethalin, quinclorac, hexazinone, mesotrione, tolfenpyrad, fluazifop, and acetamiprid with researchers at Michigan State University. Completed field notebooks were submitted to the IR-4 headquarters to support the petition processes for label registration of the herbicides on stone fruits, asparagus, snap bean, cucumber, caneberry, blueberry, grape, strawberry, and sweet corn. Over the life of the project (2010 to present), 80 different experiments have been conducted. Sixty-nine of the experiments were residue trials on 20 different fruit or vegetable crops and 30 different pesticides. Eleven of the experiments were efficacy/crop safety trials on 5 different crops with 9 different pesticides.
