  1. Crop Group Validation - Brassica Global Residue – Tomato Public Health – Mosquito Control Some Unique Trials2008/2009/2010

  2. Brief Background and Introduction • Turn over to the FRD who did the work • Special Challenges offered by the work • Differences from the norm

  3. Crop Group Validation - Brassicas Field Research Directors Brent Boutwell Chuck Farrar Study Director Bill Barney Objective: To validate the crop grouping methodology used by IR-4/EPA to set crop group tolerances

  4. 5. BRASSICA (COLE) LEAFY VEGETABLES  Rep Crops: Broccoli or cauliflower; cabbage; and mustard greens Includes: Broccoli; broccoli, Chinese (gai lon); broccoli raab (rapini); Brussels sprouts; cabbage; cabbage, Chinese (bok choy); cabbage, Chinese (napa); cabbage, Chinese mustard(gai choy); cauliflower; cavalo broccolo; collards; kale; kohlrabi; mizuna; mustard greens; mustard spinach; rape greens

  5. 5A. Head & Stem Brassica subgroup Rep Crops: Broccoli or cauliflower and cabbage  Include: Broccoli; broccoli, Chinese; brussels sprouts; cabbage; cabbage, Chinese (napa); cabbage, Chinese mustard; cauliflower; cavalo broccolo; kohlrabi 

  6. 5B. Leafy Brassica greens subgroup Rep Crop: Mustard greens  Includes: Broccoli raab; cabbage, Chinese (bok choy); collards; kale; mizuna; mustard greens; mustard spinach; rape greens 

  7. Preliminary Data • Crop Group 5 (Brassica (cole) leafy vegetables needs to be revised • Mustard greens – highest residue – rep all 5? • 3 crop groups • Flowering (broccoli, cauliflower) • Head (cabbage, brussel sprouts etc.) • Leafy (mustard greens etc.) OR • Move all leafy brassica greens to Leafy Vegetables • Include flowering and head brassica in Brassica crop group harmonize with Codex

  8. Global Residue Study - Tomatoes • FRD – Chuck Farrar • Study Director – Michael Braverman • Objective: • To test the influence of various geographic locations on the ultimate pesticide residues in field grown tomato when subjected to standardized application parameters.

  9. IR-4 Global Residue Project • Standardized application parameters • Great Training Videos – overall picture • http://www.youtube.com/watch?v=o23QUBJm7rc • http://www.youtube.com/watch?v=OL8pZs6plro

  10. Public Health Project • Field Research Directors • Don Stewart - California • David Studstill – Florida • Study Director • Keith Dorschner • Public Health Manager • Karl Malamud-Roam

  11. Public Health Project • Etofenprox – control adult mosquitoes • To propose a “blanket” tolerance to cover all crops using data from alfalfa, pasture grass and leaf lettuce • Currently can’t spray where might drift onto agricultural fields • Limits use in mosquito control surrounded by agriculture
