SLIDE CONTENTS
  1. Glyphosate-resistant Palmer amaranth Loss of Methyl Bromide Fumigant Buffer Restrictions 2008 Vegetable Update
  2. Potential MB Alternatives MIDAS 67:33 (methyl iodide + chloropicrin) DMDS 79:21 (dimethyl disulfide + chloropic.) Telone II fb chloropicrin fb Vapam (3 WAY)
  3. 2007 On Farm Replicated MB Alternative Trials 2007
  6. MIDAS AS GOOD AS MB: Crop growth, weeds, diseases, nematodes, fruit maturity, fruit size, yields WEAKNESS: Mulch type, costs
  7. Number of nustedge emerging through mulch per acre. Spring 2007. Ponder Farm.* HEAVY NUTSEDGE INFESTATIONS
  8. MIDAS WEAKNESS: Mulch type, costs *Either get a “deal” on the costs or one is forced to reduce the rate below what is effective……. On farm rates were 170-175 lb/A broadcast
  9. DMDS LEARNED IN 2007: 1. Have to use alternative mulch
  10. DMDS 74 G, LDPE DMDS 56 G, VIF
  11. DMDS 60 G, VIF DMDS 70 G, LDPE
  12. DMDS 60 G, VIF MB
  13. DMDS THINGS WE KNOW: Have to use alternative mulch Smells really really really bad!!!! THINGS STILL TO FIGURE OUT: Exact rate when used with alternative mulch Price
  14. UGA 3-WAY AS GOOD AS MB: Crop growth, weeds, diseases, nematodes, total fruit production WEAKNESS: Pain to apply, no room for error, plant back BETTER THAN MB: Earlier 1st crop pepper (more jumbo) Much cheaper
  15. MB 50:50 Not as effective as MB 67:33 Need to increase rate of 50:50 by 10-20% depending on weed infestation After getting your rate correct, you can reduce the rate up to 40% with blockade or similar type mulch Escapes will happen in the fall
  16. Long term impacts of fumigant systems on nutsedge populations per acre.* *Long term study with spring pepper and fall cucumber treated with same fumigant each year. Herbicides applied b/w crops.
  17. Long term impacts of fumigant systems on nutsedge populations per acre.* *Long term study with spring pepper and fall cucumber treated with same fumigant each year. Herbicides applied b/w crops.
  18. Economic Impact of Buffer Restrictions for Georgia.
  19. Address the variables actually impacting gas emissions! Soil moisture Soil texture Soil temperature Soil compaction Mulch types Application procedures Research Objectives
  20. Detector Tube Range 0.1 to 18 ppm GASTEC GV100S Silicone Glue Funnel glued to mulch and then left for a set amount of time
  21. Address the variables actually impacting gas emissions! Soil moisture Soil texture Soil temperature Soil compaction Application procedures Mulch types Research Objectives
  22. LDPE VIF
  24. Address the variables actually impacting gas emissions! Soil moisture Soil texture Soil temperature Soil compaction Application procedures Mulch types Research Objectives
  26. Address the variables actually impacting gas emissions! Soil moisture Soil texture Soil temperature Soil compaction Application procedures Mulch types Research Objectives
  28. Research Objectives Will likely end up with a +/- system
  29. Research Objectives Will likely end up with a +/- system Fumigant X: Buffer restriction 500 feet Ideal moisture (X – X): subtract 50 feet Ideal texture (X-X): subtract 50 feet Ideal compaction (X-X): subtract 50 feet Ideal soil temp (X-X): subtract 50 feet Mulch X or Y: subtract 50 feet Ideal acres treated/day: subtract 50 feet
  30. WHO WILL POLICE THIS?
  31. Herbicides
  32. Alanap Going Away Chemtura voluntarily canceling registration Production was stopped Oct. 2007 50,000 gal inventory 2.5 years of inventory if normal use continues Shelf life is about 3 years
  33. Chateau Row Middle Labels Third Party Registration by GFVGA for Georgia Fruiting vegetables (summer 2008) Cucurbits (summer of 2008?)
  34. Raised bed only Up to 4 oz/A (hopefully) Can not touch the mulch Product can not be effectively washed from the mulch Likely Chateau Row Middle Labels
  35. Chateau Activity After Washing Mulch Non-treated Chateau preplant applied and washed with ˝” water
  36. Likely Chateau Row Middle Label 5. Apply PRIOR to transplant Must rain after application, prior to transplant Residual control of purslane, eclipta, pigweeds, beggarweed 8. Need tank mix partner for grasses
  37. Great fit for row middles without cover crop...what happens with cover?
  38. Chateau PRE Chateau Spike Chateau POST
  39. Non-treated Chateau POST
