  5. Roundup WeatherMax Replacing Roundup UltraMax Potassium salt 5.5 lb salt/gal; 4.5 lb ae/gal 30-min rainfree warranty Claim better activity under marginal conditions Better bulk handling characteristics
  6. Roundup WeatherMax Row Middle Application Apply as hooded spray, shielded spray, or wiper application in row middles.
  7. New Vegetable Herbicides for 2003 Roundup WeatherMax Select Strategy Matrix Command Sandea
  8. Select Collard, kale, mustard, turnip Control of annual and perennial grasses Apply 6 to 8 fl oz per acre Add 1% crop oil concentrate to mix
  9. New Vegetable Herbicides for 2003 Roundup WeatherMax Select Strategy Matrix Command Sandea
  10. Strategy cucumbers, melons, squash and watermelons contains 1.6 lb ethalfluralin (Curbit) and 0.5 lb clomazone (Command) per gallon
  11. Curbit removed from the market???? replaced with Strategy
  12. Strategy Soil Broadcast Amount of Amount of Texture Rate Curbit Command Coarse 2-3 pt 1-1.5 pt 0.33-0.5 pt Medium 3-4 pt 1.5-2 pt 0.5-0.67 pt Fine 4-6 pt 2-3 pt 0.67-1 pt Georgia use rate for most fields should be 2-3 pt/A.
  13. Strategy DO NOT incorporate prior to planting DO NOT apply under or OVER row covers, mulches, or other plant covers Beware of the potential for heavy rain Do not make broadcast applications to transplants
  14. Watermelon Injury from Strategy Applied Topical 1 wk After Transplant
  15. Strategy Apply prior to weed emergence Apply to seeded crop prior to emergence, or apply as a banded spray between rows after crop emergence or transplanting.
  16. Strategy Should be able to obtain same rate of ethalfluralin (Curbit). Command should enhance activity of annual grasses (expect Texas panicum), sida, croton, lambsquarters. Buffer restrictions are identical to Command applied alone Be aware of carryover from clomazone
  17. New Vegetable Herbicides for 2003 Roundup WeatherMax Select Strategy Matrix Command Sandea
  18. Matrix Herbicide Active is rimsulfuron, DuPont product Apply in field grown tomato Apply 1 to 2 oz of product after at least two leaves Add nonionic surfactant
  19. Tomato Response to Matrix applied PRE and POST. TyTy, 2002. % injury
  20. Matrix Weed Control Specific use herbicide: Annual bluegrass Large crabgrass Foxtails Fall panicm Wild mustard Redroot pigweed Common purslane Wild radish Cocklebur* Lambsquarters* Morningglory* Hairy Nightshade* *Label suggest only suppression of these weeds.

  23. Command 3 ME Labels Be Aware of the Buffer Restrictions and Potential Off-Target Movement
  24. New Vegetable Herbicides for 2003 Roundup WeatherMax Select Strategy Matrix Command Sandea
  25. Sandea 1) cucumber, cantaloupe, tomato 2) row middle for pepper, eggplant, squash, watermelon, pumpkin* 3) preemergence in succulent snap bean* *Label anticipated in near future.
  26. Sandea - Cucumber and Cantaloupe (Section 3 Label Soon)* No Plastic: 0.5 to 0.75 oz applied after planting prior to soil cracking or apply and wait at least 7 d prior to transplant. 0.5 to 0.75 oz POST after the crop has reached the 3-5 true leaf stage, but before flowering. 0.5 to 0.75 oz POST no sooner than 14 d after transplant. Plastic: 0.5 to 0.75 oz following final bed shaping and just prior to laying plastic. Do not transplant or seed for at least 7 d after treatment.
  27. Cucumber Injury Symptoms from Sandea Applied POST
  28. Sandea - Cucumber and Cantaloupe (Section 3 Label Soon)* Postemergence application can slow growth of vines Cantaloupe seems to be more sensitive than cucumber
  29. Cucumber Response to Sandea Applied Topical. TyTy, 2002.* % stunting *Cucumber was in the 3-leaf stage at time of application.
  30. Cantaloupe Response to Sandea Applied Topical. Cordele, 2002.* % stunting *Cantaloupe was 6 inches at time of application.
  31. However, no documented yield loss at this time
  32. Sandea - Tomato (Section 3 Label) 0.5 to 0.75 oz following final bed shaping and just prior to laying plastic. Do not transplant for at least 7 d after treatment. 0.5 to 0.75 oz POST no sooner than 14 d after transplant. Directed application suggested.
  33. Sandea - tomato (Section 3 Label)* 5 trials conducted in GA during 2000, 2001, 2002. No visual injury No maturity effect No yield effect No grade effect Cooperative work with Joel Hudgins, Decatur County.
  34. Row Middle Applications (Section 3 Label)* Fruiting vegetables including pepper and eggplant Cucurbit vegetable group including cantaloupes, melons, cucumbers, squash, pumpkins, watermelon *Label anticipated in near future.
  35. Sandea for PRE Weed Control common cocklebur wild radish pigweeds common ragweed common lambsquarters yellow nutsedge - suppression purple nutsedge - suppression 2 to 3 weeks residual weed control
  36. Sandea for POST Weed Control 1-3 inch 1-9 inch passionflower cocklebur redroot pigweed ragweed pokeweed velvetleaf yellow and purple nutsedge heavy infestations may require sequential applications 2 to 3 weeks residual weed control
  37. Pigweed Control by Sandea 0.67 oz PRE = 90 to 100% (tillage that disrupts herbicide layer will reduce control drastically) 0.5 to 0.75 oz POST = 85 to 100% for 0 to 2.5 inch tall control goes downhill fast after 3 tall
  38. Non-treated Control Sandea (0.5 oz/A) PRE W1-00. Halosulfuron study with Ken Lewis in Cordele.
  39. Non-treated Control Sandea (0.5 oz/A) POST 2-leaf watermelon, 2 Palmer W1-00. Halosulfuron study with Ken Lewis in Cordele.
  40. Nutsedge Control by Sandea 0.67 oz PRE = 65-80% for about 3 wk less control if applied under plastic 0.5 to 0.67 oz POST = 85 to 95% plus some residual
  41. Sandea PRE No herbicide
  42. Non-treated control Sandea (0.5 oz/A) 2 WAP
  43. If Sandea is applied under drought stress IT WILL NOT WORK
  44. Sandea Label Recommendations Row Middle: avoid unnecessary contact with crop Application Info: apply in a minimum of 15 GPA do not use more than 2 oz per acre use non-ionic surfactant for POST weed control do not apply using air assisted (air blast) systems do not apply through irrigation do not apply when soil organophosphate insecticides are used
  45. Carryover Read Label 12 to 18 months cabbage, radish, carrot, broccoli, cauliflower, collards, onion 24 months spinach
