SLIDE CONTENTS
  1. Peanut Response to Warrant (Acetochlor) E.P. Prostko*, T.L. Grey, and D.L. Jordan
  2. U.S. Planted Acres 2012 (X 1000) NASS June 29, 2012
  3. The Peanut Weed Control Toolbox 19 active ingredients PPI/PRE Sonalan Prowl/Pendimax Dual Magnum/Generics Outlook/Propel Pursuit Spartan Charge Solicam Strongarm Valor POST Aim (Harvest Aid) Gramoxone Inteon/Firestorm/Parazone Basagran Ultra Blazer Cadre/Impose Classic Cobra Poast/Poast Plus Pursuit Select/Arrow/Trigger Storm 2,4-DB
  4. tested under experimental MON 63410 capsule suspension formulation (micro-encapsulated) 3CS Acetochlor + safener = Harness or Surpass First mention in literature was in 1970 (A new selective herbicide: MON 097, PROC NCWCC 25:56-59) Currently labeled for use in cotton, soybeans, field corn, grain sorghum MOA = 15 Very long chain fatty acid inhibitor Same MOA as metolachlor (Dual)
  5. Microencapsulation small herbicide particles surrounded by polymer shell suspended in carrier
  6. Warrant is not Lasso!!!!
  7. Objective To evaluate the tolerance of peanut to various applications of Warrant (acetochlor) under weed-free conditions.
  8. Materials and Methods I General Small-plot techniques Locations (4) Georgia Ty Ty, Plains North Carolina Rocky Mount, Lewiston 4 replications weed-free Irrigated ANOVA LSD (0.05)
  9. Materials and Methods II Locations *R/B = rip and bed
  10. Materials and Methods III Treatments PPI, PRE, EPOST, POST Warrant @ 3 or 6 pt/A Dual Magnum @ 1.33 pt/A EPOST Gramoxone Inteon @ 12 oz/A + Storm @ 16 oz/A + Warrant @ 3 pt/A or Dual Magnum @ 1.33 pt/A POST Cadre @ 4 oz/A + Warrant @ 3 pt/A or Dual Magnum @ 1.33 pt/A
  11. Results
  12. Influence of PPI Treatments on Peanut Yield (lbs/A) LSD (0.05) Ponder = 354 Plains = NS Rocky Mount = 748 Lewiston = 864
  13. Influence of PRE Treatments on Peanut Yield (lbs/A) LSD (0.05) Ponder = 354 Plains = NS Rocky Mount = 748 Lewiston = 864 -7.2%
  14. Influence of EPOST Treatments on Peanut Yield (lbs/A) LSD (0.05) Ponder = 354 Plains = NS Rocky Mount = 748 Lewiston = 864
  15. Influence of POST Treatments on Peanut Yield (lbs/A) LSD (0.05) Ponder = 354 Plains = NS Rocky Mount = 748 Lewiston = 864 -7.2%, -8.1%
  16. Influence of EPOST Gramoxone/ Storm on Peanut Yield (lbs/A) LSD (0.05) Ponder = 354 Plains = NS Rocky Mount = 748 Lewiston = 864 -9.6%
  17. Influence of POST Cadre Treatments on Peanut Yield (lbs/A) LSD (0.05) Ponder = 354 Plains = NS Rocky Mount = 748 Lewiston = 864 -9.7%
  18. Peanut Response to Warrant @ 6 pt/A PPI or PRE Ponder July 25 77 DAP NTC PPI PRE*
  19. Peanut Response to Warrant @ 6 pt/A EPOST OR POST Ponder July 25 77 DAP NTC EPOST (18 DAP) POST (36 DAP)*
  20. Summary No yield loss from any treatment at Plains, Rocky Mount, or Lewiston Significant yield loss at Ponder from Warrant @ 6 pt/A PRE and POST (7.2-7.4%) Dual Magnum @ 1.33 pt/A POST (8.1%) Gramoxone Inteon + Storm + Dual Magnum EPOST (9.6%) Cadre + Warrant (3 pt/A) POST (9.7%)
