  1. Replacing Methyl Bromide in Multiple Crop Plasticulture Stanley Culpepper University of Georgia Tifton Campus

  2. Complete pest control critical for 1st crop when growing multiple crops!

  3. Purple and Yellow Nutsedges: Most Troublesome Weeds of Cucurbits, Fruiting Vegetables, Cole Crops and Greens, and Other Vegetables

  4. Fumigants • Mulches • Herbicides MB Alternatives Require a System

  5. MIDAS 50:50 or 98:2 (methyl iodide + pic) • DMDS 79:21 (dimethyl disulfide + pic.) • Telone II fb chloropicrin fb Vapam (3 WAY) Potential MB Alternatives (Multiple crops)

  6. Numerous Mulch Options Relationship of the mulch cost and ability to reduce fumigant rate and cost

  7. DMDS 60 G, Blockade DMDS 70 G, LDPE

  8. Telone II fb Pic fb Vapam LDPE mulch Telone II fb Pic LDPE mulch Telone II fb Vapam LDPE mulch V4-05, 60 DAT

  9. Percent Purple Nutsedge Control by MB Alternative Systems. Ponder, Spring 2007. 99a 93 a Plots were 1 bed by 50 feet, evaluations are at pepper harvest.

  10. Percent Purple Nutsedge Control by MB Alternative Systems. Ponder, Spring 2007. 99a 93 a 82 b 75b Plots were 1 bed by 50 feet, evaluations are at pepper harvest.

  11. Percent Purple Nutsedge Control by MB Alternative Systems. Ponder, Spring 2007. 81 a 38 b Plots were 1 bed by 50 feet, evaluations are at pepper harvest.

  12. 3-WAY LDPE ($885 per land acre) • VS • Telone + Pic High Barrier ($880 per land acre) Determine the Economics of the System

  13. DMDS 79:21 (dimethyl disulfide + pic.) under high barrier mulch • VS • Telone II fb chloropicrin fb Vapam (3 WAY) under standard LDPE mulch Potential MB Alternatives (Multiple crops)

  14. Percent Purple Nutsedge Control by MB Alternative Systems. Ponder, Spring 2008. 99 a 99 a 99 a 99a 99a Plots were 1 bed by 50 feet, evaluations are at pepper harvest. Soil temp 60 F.

  15. Percent Purple Nutsedge Control by MB Alternative Systems. Ponder, Fall 2007. 98a 93ab 87 ab 85 b 70 c Plots were 1 bed by 50 feet, evaluations are at pepper harvest. Soil temp 93 F.

  16. PEST MANGEMENT DEPENDS ON soil moisture soil temperature soil compaction

  17. Large Crabgrass Control by MB Alternative Systems. Ponder, Spring 2008. 99a 95 a 89 b 86b 63c Plots were 1 bed by 50 feet, evaluations are at pepper harvest. Soil temp 93 F.

  18. 3-WAY LDPE DMDS + Pic Blockade

  19. Livid Amaranth Control by MB Alternative Systems. LTF, Spring 2008. 95a 95 a 85 b 75b 65c Plots were 1 bed by 50 feet, evaluations are at pepper harvest. Soil temp 93 F.

  23. Herbicides Available to Compliment the Fumigant Program for Tomato Preplant: Gramoxone, Roundup, Aim, Goal PRE: Dual Mag, Devrinol, Sandea, POST: Sencor, Sandea, Matrix, Select, Poast Directed: Sencor, Envoke 5. Row Middles: Gramoxone, Envoke, Sandea, Aim, Chateau 6. POST Harvest: Gramoxone or Roundup + Aim

  24. Yellow nutsedge plants/A after a spring pepper crop and fall cucumber crop.* *Long term study with spring pepper and fall cucumber treated with same fumigant each year. Vapam at 25 GPA and Roundup applied between crops.

  31. When Producing Multiple Crops Control weeds before and IMMEDIATELY after the crop is produced *The goal is to eliminate seed or tuber production….you are fighting the SEED BANK
