- Odor is number 1 concern Plant back: Spring up to at least 30 days in some envir Fall likely around 21 days 3. Cost is unknown????????????? Paladin (DMDS + Pic)
- Get Paladin out with 4 or 5 growers in secluded areas this fall (15-25 acres) to determine if this is a viable alternative assuming product is economical. Future of MB Alternative Efforts
- Get Paladin out with 4 or 5 growers in secluded areas this fall (15 acres or so) to determine if this is a viable alternative (assuming product is economical. 2. Summer of 2010 will be last submission of methyl bromide CUE request (if Paladin use is sustainable and economical). Future of MB Alternative Efforts
