  1. MB Alternatives – Almost DONE!!! Culpepper and Sumner University of Georgia Tifton Campus
  2. Viable MB Fumigant Alternatives MIDAS 3-WAY Paladin Herbicides
  3. MIDAS Application procedure similar to MB MIDAS is a 50:50 or 98:2 mix with Pic Use rate similar to MB Reduce use rate 40% under VIF mulches. Effective product but limited adoption because of economics.
  4. Telone/Pic/Vapam Spring applications = 16 of 17 experiments over 4 years with greater than 93% nutsedge control Vapam = 4 inches Chloropicrin = 8 inches Telone = 12 inches Ideal Placement

  10. Labeled …8 months from Nov 2009…..April or May I HOPE. 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. Paladin (DMDS + Pic)

  14. Split application Bell Pepper (Plasticulture and Bareground) PRE: 6-8 oz Dual Mag 2 to 3 lb Devrinol Command POST 1: 8-10 oz Dual Mag POST 2: Select Max as needed
  15. 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 Paladin (DMDS + Pic)
  16. Must Use Mulch Listed on Paladin Label
  17. Paladin 50 G, Blockade DMDS 70 G, LDPE
  18. Paladin (DMDS + 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 issue and must be addressed.
  19. 1. Correct Mulch – Mulch options will be listed on label 2. Moisture must be ideal Mitigating Smell Issues
  20. Start Time = 9:00 AM LDPE White Mulch
  21. 1. Correct Mulch – Mulch options will be listed on label Moisture must be ideal Compaction Mitigating Smell Issues
  22. Distance from center of bolt to center of bolt on top link was either 27.5 or 28 inches
  23. LDPE 28” LDPE 27.5” 15 % reduction due to increased bed compaction
  24. Odor is number 1 concern Plant back: Spring up to at least 30 days in some envir Fall likely around 21 days 3. Cost is unknown????????????? Paladin (DMDS + Pic)
  25. Get Paladin out with 4 or 5 growers in secluded areas this fall (15-25 acres) to determine if this is a viable alternative assuming product is economical. Future of MB Alternative Efforts
  26. Get Paladin out with 4 or 5 growers in secluded areas this fall (15 acres or so) to determine if this is a viable alternative (assuming product is economical. 2. Summer of 2010 will be last submission of methyl bromide CUE request (if Paladin use is sustainable and economical). Future of MB Alternative Efforts
  27. Get Paladin out with 4 or 5 growers in secluded areas this fall (15 acres or so) to determine if this is a viable alternative (assuming product is economical. 2. Summer of 2010 will be last submission of methyl bromide CUE request (if Paladin use is sustainable and economical). 3. One year from today discuss results from Paladin efforts and one additional fumigant system in development. Future of MB Alternative Efforts
