  1. Why Are Some Herbicides Not Recommended By UGA? Eric P. Prostko and A. Stanley Culpepper Professors/Extension Weed Specialists Dept. Crop & Soil Sciences
  2. U.S. Crop Production 2015 Acres Planted (X 1000) Source: NASS - Crop Production (November 2015)
  3. Cotton vs. Soybean in SE 1,275,000 acres harvested in 2015 1.6% of US Total 1,720,000 acres harvested in 2015 21.1% of US Total Source: USDA/NASS, Crop Production (November 2015)
  4. Herbicide Advertisements Progressive Farmer - November 2015
  5. Herbicides You Might Not Be Too Familiar With
  6. Reasons for Not Recommending limited data would prefer 2-3 years of data 43 peanut trials with pyroxasulfone (Zidua) crop injury carryover weed efficacy Texas panicum cost/A any better than current standards?
  7. PRE Applied Balance Flexx Injury on Field Corn CN-10-12 April 6 11 DAT
  8. Peanut Injury with Anthem Flex 4SE 22 DAT NTC 3.0 oz/A 3.75 oz/A 6.0 oz/A 7.5 oz/A PE-01-15 May 19
  9. Peanut Yield Response to PRE Applications of Anthem Flex - 2015 PE-01-15 Weed-free LSD 0.10 = 906 CV = 13.06 Anthem Flex 4SE = pyroxasulfone (3.733 lbs) + carfentrazone (0.267 lbs)
  10. Cadre vs. Flame in Peanut imazapic Cadre - US Flame Australia Flame registered for PRE/POST us in peanut Cadre Registered for POST use only WHY?? Increased rotational crop issues (i.e. cotton) less control of Florida beggarweed
  11. Soil Types Southeast vs. Midwest
  12. Midwest Weed Control Programs Source: Dr. Bill Johnson, Purdue University (11/12/2015)
  13. Bottom Line usually a very good reason why herbicides are not recommended by UGA or listed in Pest Control Handbook do not assume a label in another state/country will work in GA!
