Abstract/Contents: | "Methyl bromide (MB) is an odorless, colorless gas that has been used nearly seventy-five years as a preplant soil-fumigant in agriculture throughout the world. MB was designated an ozone depleting substance resulting in a phase out of use for most agricultural commodities. MB label changes will eliminate all golf course related uses at the end of 2013 leaving that segment of the turf industry in a quandary. Our research has sought to identify effective and affordable alternatives to MB for use on warm-season golf courses and sod production farms. Iodomethane (IM) (98:2) applied at 100 lbs ac-1 under a virtually impermeable film provided control of Commelina benghalensis and Panicum ramosum equal to that of MB. Addtionally, IM applied at rates >= 125 lbs ac-1 under totally impermeable film could effectively control troublesome Cynodon and Cyperus species initially but control waned over time. IM proved to be an effective MB alternative but the manufacturer discontinued its use in 2012. MB rate reduction studies demonstrated that control of Commelina benghalensis and Panicum ramosum with MB under TIF was comparable at all rates (100 - 400 lbs ac-1). However, in another study, reduced rates (< 400 lbs ac-1 of tractor-applied MB reduced the number of Cynodon dactylon plants (56 DAA) and reduced the % Cynodon ground cover (110 DAA), but only the standard 400 lbs ac-1 rate provided the level of bermudagrass control necessary to avoid further contamination. Reduced rates of MB applied using "hot gas" type methods were less effective in controlling bermudagrass and nutsedge - regardless of plastic type. The use of steam for soil disinfestation provided acceptable control of several troublesome weeds. However, the costs associated with steam disinfestation (~ two-times MB) are prohibitive and this method is not currently a commercially available option in the turf industry." |
