  19. Some things I have heard said about pyroxasulfone? Its way better than Dual (S-metolachlor) or Warrant (acetochlor) on pigweed, grasses, and annual mg?? IS IT ALWAYS BETTER??????? What about other weeds? Florida beggarweed wild radish

  32. Final Thoughts? Anthem Flex use rate in peanut? 2.7-3.0 oz/A How much will Anthem Flex cost/A? Zidua 4.17SC @ 2.5 oz/A (0.081 lb ai/A) = ~$11-$13 Dual Magnum 7.62EC @ 16 oz/A = ~$8/A Warrant 3ME @ 48 oz/A = ~$7-8/A Need more fungicide tank-mix data! Miravis, Elatus, Lucento Is pyroxasulfone really better (all the time) on IPOSP, RAPRA, and DEDTO?
