SLIDE CONTENTS
  1. Peanut Tolerance to KIH-485 in Georgia E. P. Prostko and T.L Grey Department of Crop & Soil Sciences The University of Georgia APRES-2008
  2. KIH-485 Pyroxasulfone Kumiai Developed for corn and soybeans PRE Herbicide Family Sulfonylioxazoline (?) Herbicide Mode of Action (?) plant growth inhibitor that affects apical meristem and coleoptile development of plants after seed germination Low use rates
  3. KIH-485 Literature Review Steele et al., Weed Technology. 2005. 19:866-869. (TX) Texas panicum (66-90% control) Palmer amaranth (97-98% control) Velvetleaf (90-97% control) Geier et al., Weed Technology. 2006. 20:622-626. (KS) Longspine sandbur (64-75% control) Green foxtail (78-100% control) Palmer amaranth (80-99% control) Puncturevine (86-100% control) King et al., Weed Technology. 2007. 21:578-582. (VA) Shattercane (64-93% control)
  4. Texas Panicum Control in Georgia Field Corn with KIH-485 Applied PRE (Photo @ 53 DAT) - 2007 NTC KIH-485 85WG @ 4.2 oz/A (0.223 lb ai/A)
  5. Wild Radish Control in Georgia Field Corn with KIH-485 Applied PRE (Photo @ 43 DAT) - 2007 NTC KIH-485 85WG @ 1.67 oz/A (0.089 lb ai/A)
  6. Tropical Spiderwort Control in Georgia Peanuts with KIH-485 (15 DAT) - 2007 NTC Gramoxone Inteon @ 12 oz/A KIH-485 @ 4.2 oz/A Storm @ 12 oz/A 80/20 @ 0.25% v/v PE-10-07 NTC
  7. Objective Evaluate the response of peanut to PRE and POST applications of KIH-485.
  8. Materials and Methods 2 locations (2007) Tifton Plains Weed-free factorial design Timing (2) PRE or POST Rate (5) KIH-485 85WG 0,2,4,6,8 oz/A 80/20 @ 0.25% v/v added to POST Small-plot techniques

  12. Results No interaction between timing or rate at either location. No significant crop injury was observed. (= 10% stunting) No effect on TSWV.
  13. The influence of KIH-485 85WG timing on peanut yield. (P = 0.398) (P = 0.965) Averaged over 5 rates (0, 2, 4, 6, 8 oz/A)
  14. The influence of KIH-485 85WG rate (oz/A) on peanut yield. (P = 0.171) (P = 0.174) Averaged over 2 timings (PRE and POST)
  15. Peanut Response to KIH-485 (2007) NTC KIH-485 85WG @ 8.0 oz/A PRE KIH-485 85WG @ 8.0 oz/A + 80/20 @ 0.25% v/v POST PD = May 8 PRE = May 10 POST = June 21 PHOTO = June 29 Ponder Farm
  16. Summary Peanut had acceptable tolerance to PRE and POST applications of KIH-485 in 2007. Similar studies are being repeated in 2008. Injury at Plains Moisture may be major a factor that influences peanut tolerance to KIH-485. POST treatments only??
  17. Peanut Response to KIH-485 (2008) NTC KIH-485 85WG @ 8.0 oz/A PRE PD = May 12 PRE = May 13 PHOTO = May 28 Ponder Farm
  18. Peanut Response to KIH-485 (2008) NTC KIH-485 85WG @ 8.0 oz/A PRE KIH-485 85WG @ 8.0 oz/A + 80/20 @ 0.25% v/v POST PD = May 12 PRE = May 13 POST = June 25 PHOTO = July 8 Ponder Farm
