| Abstract/Contents: | "Iodomethane (methyl iodide) received federal registration as a fumigant alternative to methyl bromide. However, limited data exists on its effectiveness in turf and sod preplant situations. Experiments were conducted in 2006 and 2007 to evaluate two iodomethane formulations: 98:2 and 50:50 (iodomethane:chloropicrin). The 98:2 formulation was tested at 112 and 269 kgs ha-1 in 2006 and at 112, 196, and 269 kgs ha-1 in 2007. The 50:50 formulation was tested at 224 and 392 kgs ha-1 in 2006 and 224, 280, 336, and 392 kgs ha-1 in 2007. A methyl bromide treatment (392 kgs ha-1) was included for comparative purposes. The experiments were conducted at the University of Florida, West Florida Research and Education Center near Jay. Plots areas were cultivated prior to fumigant application. All fumigation treatments were applied by a commercial applicator and plots measured 9.1 m X 15.2 m. Two passes with the fumigation applicator were made through each plot and each plot was covered with a plastic tarp. Tarps were removed 7 days after treatment (DAT). 'Tifway 419' bermudagrass (Cynodon dactylon X C. transvaalensis) was sprigged on three different sprigging dates in 2006 (7, 14 and 21 DAT) and on two dates in 2007 (14 and 21 DAT). Sprigs were planted at 40 m3 ha-1 using a tractor-pulled sprigger in 4.6 m wide strips for each plot. Sprigs were watered as needed for establishment and fertilized weekly when conditions were favorable for bermudagrass growth. Visual turfgrass and weed control data were collected throughout the studies. Little to no bermudagrass injury was observed for all treatments. Cocklebur (XANST) was effectively controlled by all rates of the 50:50 formulation but not the 98:2 formulation. Carpetweed (MOLVE), pigweed (AMARE), and wild radish (RAPRA) were not effectively controlled with either formulation. Control of sicklepod (CASOB) was good with the 50:50 formulation but poor with the 98:2 formulation of iodomethane. Only methyl bromide provided acceptable (>=70%) purple nutsedge (CYPRO) control in both years. All other treatments provided <=60% purple nutsedge control in 2006. In 2007, the 98:2 iodomethane treatments provided only 65% control of purple nutsedge. The 50:50 formulations provided only 40% control of purple nutsedge." |
