  12. Nutsedge Response to the 3-WAY, Paladin Pic, and WSP plus herbicides in PEPPER. TyTy, 2010. LSD for spring = 6; LSD for fall = 7. Plots were 1 bed by 50 feet. Spring soil temp 55 F; Fall soil temp 89. 97 3-WAY Paladin Pic WSP 96 95 94 97 90
  13. Telone/Pic/Vapam Spring applications = 17 of 18 experiments over 5 years with greater than 93% nutsedge control (less effective in the fall) Vapam = 4 inches Chloropicrin = 8 inches Telone = 12 inches Ideal Placement Vapam = 4 inches Pic Chlor 60 = 8 inch More Common
  14. Note moisture and compaction
  16. Paladin Labeled for Georgia in Nov/Dec Recommend 79:21 mixture with chloropicrin Same application procedures as MB Culpepper rate = 50 GPA (if economical) Excellent nutsedge control; needs help on annual grasses, pigweed, and likely other small seeded annual broadleaf weeds. Paladin Pic (DMDS + Pic)

  24. Paladin Pic Labeled ???? 79:21 mixture with chloropicrin. Same application procedures as MB. Excellent nutsedge control; needs help on annual grasses, pigweed, and likely other small seeded annual broadleaf weeds. Must use high barrier mulch. Smell is a serious concern; must be addressed.
  25. 1. Moisture must be ideal Compaction Mitigating Smell Issues
  27. 1. Moisture must be ideal Compaction No previous crop residue Purge injection lines before lifting shank from soil. Mitigating Smell Issues

  31. Potentially new fumigant system being studied. WSP is just a code not a trade name. Data in 2010 looks very good. WSP?

  33. Response of Root Knot nematode to the WSP. Langston, 2010. 0 b Incidence 97 a 8 b Severity 3.6 a 0.008 b 0.05 b
  34. Jumbo pepper yield with a fall fumigation. Four harvests (box/A). TyTy, 2010. 174 c Pic Chlor 60 Pal Pic WSP 648 b 974 a 1048 a 588 b 1080 a 1042 a 21 G, LDPE 35 G, VIF 21 G, VIF 35 G, LDPE 3-WAY
  35. 4. High barrier (VIF) mulch will be needed. Same application procedures as MB. Minimal buffers in 2012? 7. Three large on farm studies lined up. 8. May be gone in a month or we may be recommending within a year. WSP?
  36. Several of these labels may be GA ONLY Herbicide Program for Pepper: 1. Devrinol applied preplant under mulch. (Command?) 2. Dual Magnum applied topically 7 to 10 d after transplant 3. Select Max without adjuvant as needed (grass <3 inch) Herbicide Program for Tomato and Pepper Herbicide Program for Tomato: 1. Devrinol + Dual Magnum preplant under mulch. (Metribuzin?) 2. Sandea POST 3. Select Max without adjuvant as needed (grass <3 inch) Reflex could be added preplant to both crops once labeled.
  37. Several of these labels may be GA ONLY Herbicide Preplant Application Method

  39. Fumigant + Mulch + Herbicides Expense MB = $1276 3-WAY = $900 Paladin Pic = $1080 WSP = $921 Pic Chlor 60 (35 G)= $1133 Pic Chlor 60 (21 G)= $877 Cost per acre land assuming treating 53% of the land area.
