Significant Efforts with WSP in 2011
New fumigant system-minimal release in 2012. Mixture of Paladin, chloropicirn, and Telone II.* Trade name in development. Twenty eight acres in 2011 (4 application times) Data in 2010 and 2011 looks very good. WSP *Patent pending

Limit use, but would suggest trying. Use high barrier mulch on Paladin label. Do not cut rate (350 lb/A). An odor does exist, be cautious. Have TriEst-Ag present if at all possible. Your feedback is definitely needed! WSP
Less effective than UGA 3-WAY, WSP, or Paladin Pic. However, with one or two crop only systems it can be effective, especially when Sandea can be used. Limited odor concerns. Easy to apply. Herbicides needed! Pic Chlor 60

Herbicide boom Herbicide Preplant Application Method
Herbicide Program for Pepper: 1. Devrinol applied preplant under mulch. (Command?) 2. Dual Magnum applied topically 7 to 10 d after transplant 3. Select Max without adjuvant as needed (grass <3 inch) Herbicide Program for Eggplant and Pepper Several of these labels are for GA growers only. Reflex label for pepper expected early 2012. Herbicide Program for Eggplant: 1. Devrinol applied preplant under mulch. 2. Select Max without adjuvant as needed (grass <3 inch)
Herbicide Program Tomato Herbicide Program for Tomato SOON: 1. Devrinol preplant under mulch. (Metribuzin?) 2. Dual Magnum applied topically 7 to 10 d after transplant 3. Sandea POST 4. Select Max without adjuvant as needed (grass <3 inch) Herbicide Program for Tomato CURRENTLY: 1. Devrinol + Dual Magnum preplant under mulch. (Metribuzin?) 2. Sandea POST 3. Select Max without adjuvant as needed (grass <3 inch) Several of these labels are for GA growers only. Reflex label for pepper expected early 2012.
Mulch stability of high barrier films. Rise in fumigant/mulch system costs. Planting interval after fumigating. ISSUES!

In cooperation with TriEst Ag, our goal will be to develop WSP and Paladin Pic systems with 2 or 3 mulches with high *Product quality *Product stability *Manufacture stability *Economical Mulch Stability Effort
Fumigant + Mulch + Herbicide Costs to Growers Rise Sharply 3-WAY = $843 $984 Cost per acre land assuming treating 53% of the land area, 5 ft center. 2011 2012 +14.3%

This is the one area it does not currently appear that we will be able to replace methyl bromide. UGA 3-WAY: 15 to 30 days Paladin Pic: 21-40 days WSP: ????? Planting Interval For Fumigants
