  7. Untreated Strongarm applied 17 DAP Strongarm applied 31 DAP PE-24-03 46 DAP Tropical spiderwort control with POST applied Strongarm, 2003
  8. Bristly starbur control with POST applications of Strongarm, 2003 1-15” tall bristly starbur Included 80/20 @ 0.25% v/v
  9. Bristly Starbur Control with POST Applied Strongarm PE-27-03 32 DAT Untreated Strongarm @ 0.45 ozs/A Strongarm @ 0.113 ozs/A
  10. Strongarm POST Test - Growth Stages Ty-Ty, GA 2003
  11. Annual morningglory control with POST applications of Strongarm - 11 WAP Averaged over 3 timings (1, 3, and 5 WAP) LSD 0.05 = 4
  12. Florida beggarweed control with POST applications of Strongarm - 11 WAP Averaged over 3 timings (1, 3, and 5 WAP) LSD 0.05 = 12
  13. Untreated Strongarm 0.45 ozs/A + 80/20 @ 0.25% v/v (Applied 5 WAP) 11 WAP

  15. PE-15-03 67 DAT Wild poinsettia control with POST herbicides, 2003 Untreated Cadre @ 1.44 ozs/A Strongarm @ 0.45 ozs/A
  16. Wild radish control with POST applied Strongarm LSD 0.05 = 11 (3-4 leaf) (flowering) (7” rosette) Included 80/20 @ 0.25% v/v 40 day after first timing
  17. Wild Radish Control with POST Applied Strongarm (1”, 3-4 leaf) Untreated Strongarm 0.45 ozs/A Strongarm 0.225 ozs/A 40 DAT
  18. Summary good to excellent POST control of several species reduced rates on sensitive species such as bristly starbur, annual morningglory, wild radish timing is critical on some species such as beggarweed no POST control of sicklepod
  19. Future Research variety tolerance crop rotations longer or shorter???? other weed species horseweed copperleaf eclipta
