SLIDE CONTENTS
  1. 2016 Vegetable Weed Control DIVERSIFICATION
  2. Focus Points Weed Seed Production Tillage-Stale Seedbed Avoiding Herbicide Injury Specific Crop Programs
  3. About 3 wk after emergence = tubers
  4. Tillage can be helpful……or harmful.
  5. Tillage can be helpful……Stale Seedbed. Stimulation of weed seed germination can be helpful in a stale seedbed approach in crops challenged with weeds. At times, at least half your weeds will emerge in the first 7-10 days after a tillage. Prepare bed for planting, spray with Roundup or Gramoxone or both prior to planting. Double Knock: Spray Roundup fb Gramoxone 5-7 days later.
  7. No Deep Tillage Deep Turn No Herbicide Treatment Number of Palmer Amaranth Plants During Early Season. Macon Co., Georgia 2008.*
  8. Plowing emerged weeds is an effective tool. Plowing up residual herbicide….not so much. If plowing, apply residual herbicide after plowing if possible. Tillage can be helpful……Plowing.
  9. Avoiding Herbicide Injury Greatly influenced by excess moisture, cold, and incorrect spray calibration.
  10. Seed needs to imbibe water free of herbicides
  11. Seed needs to imbibe water free of herbicides Factors Reducing Injury High vigor seed Ideal plant depth Right rate Plant into moist soil Smart irrigation
  12. Roundup Preplant No Roundup
  13. Sandea Dissipation on Mulch Work by Tim Grey
  14. Non-treated Sandea prior to transplant
  15. Herbicide Preplant Application Procedure in Plasticulture is Critical
  16. Lima, Snap, Southern Pea Start Clean: Tillage/Roundup/Gramoxon Treflan/Prowl preplant incorporated
  17. Lima, Snap, Southern Pea (BASE PROGRAM) Start Clean: Tillage/Roundup/Gramoxone Treflan/Prowl preplant incorporated Dual Magnum preemergence Grass herbicide as needed POST Dual Magnum directed while cultivating
  18. Lima Sandea PRE Sandea POST Basagran Pursuit PRE Snap Bean Reflex PRE Reflex POST Sandea PRE Sandea POST Basagran Pursuit PRE South. Pea Basagran Pursuit PRE Pursuit POST
  19. Lima, Snap, Lima, Cowpea, Lima, Cowpea
  20. Lima, Snap, Lima, Cowpea, Lima, Cowpea Reflex 8 oz/A + Dual Magnum 12 oz/A
  21. Southern Pea Treflan PPI Treflan + Reflex PPI Reflex + NIS POST Reflex at 1 pt/A
  22. Bareground (most aggressive): 1. Incorporate Treflan and prepare beds 2. Apply Goal (add gramoxone if weeds up) 3. Lightly irrigate; wait 3 days with 1 sunny day 4. Transplant 5. Irrigate before applying Dual Mag. 6. Apply 10-12 oz of Dual Mag. topically 7-10 DAP. 7. Grass herbicide as needed. Cabbage, Broccoli, and Cauliflower (transplants) Cultivation kills the herbicide program!!!!!!!!!!!!!!!
  23. Bareground (most aggressive): 1. Incorporate Treflan and prepare beds 2. Apply Goal (add gramoxone if weeds up) 3. Lightly irrigate; wait 1 to 2 sunny days 4. Transplant 5. Irrigate before applying Dual Mag. 6. Apply 10-12 oz of Dual Mag. topically 7-10 DAP. 7. Grass herbicide as needed. Collard (transplants) Cultivation kills the herbicide program!!!!!!!!!!!!!!!
  24. 1. Incorporate Treflan 2. Seed 3. Spray 12 oz of Dual Magnum topically when 3”. 4. Grass herbicide as needed. Cabbage, Broccoli, Cauliflower, Collards (seeded) Cultivation kills the herbicide program!!!!!!!!!!!!!!!
  25. 1. Incorporate Treflan 2. Seed 3. Grass herbicide as needed. Turnips and Mustard (seeded) Cultivation kills the herbicide program!!!!!!!!!!!!!!!
  26. Grower Standard + Future Product? Grower Standard (not a check!!) Notice pigweed
  27. Fruiting Vegetables On Mulch Herbicides under mulch generally don’t perform well and can be problematic (injury, carryover, etc.)
  28. BELL PEPPER HERBICIDE PROGRAM Preplant under mulch Topical 7-10 d after transplant Topical as needed 1.Devrinol 2.Devrinol + Command 3.Devrinol + Reflex (Dual is labeled but can cause Stunting) Dual Magnum 10-12 oz/A Select Max TapOut No adjuvant needed
  29. REFLEX IN TOMATO/PEPPER EXCELLENT CROP TOLERANCE; 50-70% yellow nutsedge under mulch control, excellent Pigweed control LABELED
  30. REFLEX PREPLANT ON YELLOW NUTSEDGE
  31. No Reflex Reflex 1 pt/A applied 205 days before transplanting
  32. Palmer Amaranth Control With Pic Chlor 60. Tift Co., 2013. Plus Dual Mag 12 oz/A No Herbicide
  33. TOMATO HERBICIDE PROGRAM Preplant under mulch Topical 10-14 d after transplant; pre-bloom Topical as needed 1.Devrinol + Dual Mag. 2.Devrinol + metribuzin 3.Devrinol + Reflex Sandea 0.75 oz Dual Magnum 1. Select Max No adjuvant needed
  34. No Dual Magnum
  35. Dual Magnum 8 oz/A
  36. Dual Magnum 12 oz/A
  37. Dual Magnum 16 oz/A
  38. Dual Magnum 24 oz/A
  39. EGGPLANT HERBICIDE PROGRAM Preplant under mulch No POST broadleaf option Topical as needed Devrinol Select Max TapOut
  40. Control Dual Magnum
  42. Sinbar + Reflex + Yellow + Roundup or Gramoxone Under mulch? Reflex/Sinbar/Sandea? Metam sodium/Pic
  43. Sinbar + Reflex + Yellow + Roundup or Gramoxone Under mulch? Reflex/Sinbar/Sandea-- Metam sodium/Pic
  44. Other Thoughts Sinbar: great tool except intercropping Sandea: 7 d preplant, RM Yellow: great tool, not under mulch Select Max: least injurious Rotational: Staple, Envoke, Cadre, Strongarm are often problematic
  45. Watermelon and Cantaloupe - Row middle bareground: 8 to 12 oz/A - Row middle mulch: 12 to 16 oz/A - Do not apply topically - Do not broadcast over mulch 2015 New Labels-Dual Magnum
  46. Mulched watermelon injury to Dual Magnum applied post-transplant on mulch. TyTy, 2010. 8 d 16 c 40 b 8 oz 12 oz 50 a 24 oz 36 oz %
  47. Cantaloupe – Preplant/At Plant Command: watch carryover Curbit: don’t put under plastic Metam: under mulch?? Sandea: 7 day preplant
  48. Cantaloupe – Preplant/At Plant Sandea: POST for nutsedge Select Max: Grasses 3” or smaller Treflan: row middle
  49. Cantaloupe – Preplant/At Plant Sandea: POST for nutsedge Select Max: Grasses 3” or smaller Treflan: row middle NEED NEW TOOLS!!!!!
  50. Squash – Last 2 years game change Interestingly seeded squash will likely give you the best control options. Curbit + Reflex PRE Dual Magnum POST ONCE LABELED
  51. REFLEX - SQUASH Bareground seed: 8 oz/A PRE + yellow Bareground transplants: A. Prepare land; B. Apply 8 oz Reflex C. Irrigate D. Punch hole and transplant
  52. Summer Squash (Yellow & Zucchini) Dual Magnum Bareground seed: 8-12 oz POST after 3” Bareground transplants: 8-12 oz 10-14 DAT Mulch seed: 8-12 oz POST after 3” Mulch transplants: 8-12 oz 7-10 DAT.
