  1. 2012 Cotton Production Meeting Stanley Culpepper, University of Georgia, Tifton

  2. Diversity and Integration: Keys to Surviving in a Palmer World BIOLOGY Integrated to remain sustainable Management programs

  3. What makes Palmer special? BIOLOGY Integrated to remain sustainable Management programs

  4. Concept of Overlapping Residuals Critical herbicide concentration

  5. RR Reduced Tillage Cotton Systems. 2012. APPLY VALOR AND/OR DIREX TO EVERY ACRE; MUST BE PALMER FREE AT PLANTING!!!

  6. RR Reduced Tillage Cotton Systems. 2012. RU + Staple wins 7 out of 10 times!

  7. RR Reduced Tillage Cotton Systems. 2012. Consider direct spraying Warrant mixture if more than 6 leaf cotton!

  8. RR Reduced Tillage Cotton Systems. 2012. No brainer…..Suprend great option as well!

  9. RR Reduced Tillage Cotton Systems. 2012. No brainer…..Suprend great option as well!

  10. RR Reduced Tillage Cotton Systems. 2012.

  11. RR Reduced Tillage Cotton Systems. 2012. Allows 2 residuals at planting instead of 3 to reduce injury. Perfect timing for thrips application! Allows time for activation before PRE breaks down!

  12. RR Conventional Tillage Cotton Systems. 2012. Need to plant within 5 days of PPI

  13. Percent Palmer Control, 2010. TyTy, GA. 38 DAT. 99 a 92 b 80 c 3 d PPI Field cultivator PPI Disk PRE PPI Rototiller Reflex applied at 1 pt in combination with Prowl.

  14. RR Conventional Tillage Cotton Systems. 2012.

  15. RR Conventional Tillage Cotton Systems. 2012.

  16. Roundup Ready PLUS Cotton Incentive (Up to $22) *Will pay on 2 applications

  17. Impact of GR Palmer amaranth on GA. 37 % acres 18 0 Ignite-based Programs

  18. GR Palmer amaranth control in dryland conservation tillage systems Prowl + Reflex PRE Roundup+ Dual POST Diuron + MSMA PD Prowl + Reflex PRE Ignite + Dual POST Diuron + MSMA PD

  19. Making the most of your Ignite! • Water volume • Spray tip and pressure • Time of day you spray • Palmer size

  20. GreenLeaf TwinJet Air Induction

  21. MOST IMPORTANT IS TO HAVE PRESSURE AND NOZZLES THAT GENERALTE MEDIUM (300-400 MICRONS)

  22. Late-season Palmer control with Ignite as influenced by time of day. Macon Co. Dryland 97 a 99 a % 50 b 8 c 6.45 am 12 – 1 pm 6:30 – 7:00 pm 12 – 1 am Time of Day for Ignite Applications Ignite POST 1 (5” Palmer), Ignite POST 2 (18 d later), Diuron + MSMA layby

  23. 6.45 am 12:30 pm Ignite POST (5”Palmer), Ignite POST 2 (18 d later), diuron + MSMA layby

  24. Making the most of your Ignite Time GPA Nozzle Rate

  25. Making the most of your Ignite Time GPA Biggest pigweed in the field is 3 inches!!!!!!!!!!!!!!!! Nozzle Rate

  26. 32 oz/A Gly 4 fb 29 oz/A Ignite on 12” Palmer

  27. Controlling Palmer in LL Cotton. 2012.

  28. Controlling Palmer in LL Cotton. 2012. WANT RESIDUAL HERE BUT KINDA STUCK???

  29. Controlling Palmer in LL Cotton. 2012.

  30. 2012 Ignite Based Programs • LibertyLink • GlyTol LibertyLink • WideStrike

  31. 2012 Ignite Based Programs • LibertyLink • Advantage: no injury issue with Ignite • Disadvantage: no tolerance to Roundup

  32. 1 leaf 6 leaf Ignite 32 oz Ignite 32 oz Ignite 32 oz + Dual Ignite 32 oz Ignite 32 oz + Dual Ignite 32 oz + Warrant Ignite 43 oz Ignite 43 oz ST 4145 Seed Cotton Yield In Response to Ignite-Based Programs. 2012. No Ignite: 2925 3015 3010 2940 2940 All systems had diuron PRE and diuron + MSMA applied at layby.

  33. 2012 Ignite Based Programs • LibertyLink • Advantage: no injury issue with Ignite • Disadvantage: no tolerance to Roundup • GlyTol LibertyLink • Advantage: no injury issue with Ignite or Roundup • Disadvantage: limited supply, less data on yield

  34. Percent GlyTol + LL cotton injury from topical applications 7 DAT. Moultrie, 2010 8 leaf cotton 2 a 18 b 0 a 1 a WMax 33 oz Ignite 44 oz WMax + Ignite WMax + Ignite + Dual (1 pt)

  35. Percent GlyTol + LL cotton injury from topical applications 7 DAT. Moultrie, 2010 8 leaf cotton Sequential applications of Ignite and Roundup in 2012 to avoid antagonsim? 2 a 18 b 0 a 1 a WMax 33 oz Ignite 44 oz WMax + Ignite WMax + Ignite + Dual (1 pt)

  36. 2012 Ignite Based Programs • LibertyLink • Advantage: no injury issue with Ignite • Disadvantage: no tolerance to Roundup • GlyTol LibertyLink • Advantage: no injury issue with Ignite or Roundup • Disadvantage: limited supply, less data on yield • WideStrike • Advantage: no injury issue Roundup, only tolerance to Ignite • Disadvantage: You will get injury from Ignite

  37. Phytogen Widestrike Cotton • Confers tolerance to Ignite • Tolerance not complete; injury will occur and yield loss can occur if you don’t know what you are doing. • According to EPA, Ignite can be applied to widestrike cotton. • However, grower is liable as neither Bayer nor Dow recommend or warrant the use of Ignite on Widestrike cotton

  38. 1 leaf 6 leaf Ignite 32 oz Ignite 32 oz Ignite 32 oz + Dual Ignite 32 oz Ignite 32 oz + Dual Ignite 32 oz + Warrant Ignite 43 oz Ignite 43 oz ST 4145 Seed Cotton Yield In Response to Ignite-Based Programs. 2012. No Ignite: 2970 2916 a 2831 ab 2850 ab 2680 b All systems had diuron PRE and diuron + MSMA applied at layby.

  39. Six Inch GR Palmer Response to Layby or Hooded Spray Options. Macon, 2012. 95 a 96 a 77 b 69 c Gramoxone + Direx Direx + MSMA Ignite + Valor Ignite

  40. GR Palmer Response to Layby or Hooded Spray Options. Macon, 2012. 95 a 96 a 77 b 69 c Gramoxone + Direx Ignite + Valor Ignite Direx + MSMA DO NOT APPLY IGNITE MORE THAN TWICE A YEAR

  41. Herbicide Resistance: Will You Survive? 1,089,000 plants per acre 25 plants per square foot emerge = If resistance is one in a billion then you only need 918 acres to find that plant. (historically resistance is 1 plant in population of 1-10 million…9.18 acres)

  42. Time Line For Significant Events in Georgia Weed Management 2004: GR Palmer Began Changing Agriculture Forever 2009-2011: Significant Adoption of Ignite Programs 2012: GlyTol + LL Cotton Commercialized 2016: Glyphosate + Glufosinate + 2,4-D Glyphosate + Glufosinate + Dicamba 2017/2018: Glyphosate + Glufosinate + HPPD

  43. 12 DAT 24 DAT 2,4-D (3.8 L) 1.5 pt to 8 inch Palmer

  44. 12 DAT 24 DAT Clarity 1 pt 8 inch Palmer

  45. Managing Palmer Amaranth in DryLand Production!! Tomorrow if Ignite works Herbicide Cost of $39/A Today RR System Herbicide Cost of $59/A

  46. Heavy Residue Deep Turn Georgia growers will not economically survive relying on just herbicides!!!! Cultivate Hand weed

  47. Potential Benefits for Georgia Growers • Improved Palmer control • Protect herbicide chemistry • Labor (compared to tillage) • Wind and water erosion • Prevents GR horseweed • Prevents/Lessons GR ryegrass • Moisture conservation • Reduce herbicide inputs • Higher yields on dryland • Protection from EPA • Reduces thrips damage

  48. Potential Challenges for Georgia Growers Ripper shank rye • Blowout impacting stand • Incorporate herbicides with when strip tilling • Spray then roll, roll then spray? • Time to get established • Increased fertilizer • Rubber wheel system • Grower comfort

  49. GR Palmer amaranth influence on cotton lint yield (lb/A) in the Roundup system.* 790 a 690 b 592 c 480 d Inversion + rye Deep inversion Rye Weeds *RR System: Diuron + Reflex + Staple fb Roundup + Parrlay fb Direx + MSMA
