| Abstract/Contents: | "Goosegrass (Eleusine indica (L.) Gaertn.) is a problematic summer annual weed well adapted to turfgrass management. It has a rapid establishment and growth in spring and summer, it is a prolific seed producer and very common in stressed turf or compacted areas. The best program for goosegrass control is preemergence herbicide use rather than a postemergence control. Dinitroanilines (DNA) herbicides are widely used for goosegrass preemergence control but overuse has resulted in resistance issues throughout Southeast USA. Several new preemergence herbicides with different modes of action to that of DNAs are available with potential to control goosegrass in turf. An experiment was conducted from March to September 2011 in a golf course fairway with a long history of prodiamine use every year in spring (10 years). The following herbicides were applied with a CO2 pressured sprayer delivering 374 L ha-1 to 1.5 x 3 m plots: dimethenamid at 1.68 or 1.68 + 1.68 kg a.i./ha, dithiopyr at 0.38 + 0.38 kg a.i./ha, indaziflam at 0.07 or 0.035 + 0.035 kg a.i./ha, oxadiazon at 4.5 or 2.25 + 2.25 kg a.i./ha, prodiamine at 0.72 + 0.72 kg a.i./ha and sulfentrazone at 0.38 or 0.38 + 0.38 kg a.i./ha. Experimental design was a randomized complete block design with four replications. Initial applications were made on March 8 and the sequential treatment was made after eight weeks. By 4 months after initial treatment, two applications of dimethenamid, indaziflam and oxadiazon provided >80% goosegrass control while sulfentrazone applied twice gave 60% control. Dithiopyr and prodiamine provided less than 19% goosegrass control on all dates. By September 19th, single and sequential applications of indaziflam and oxadiazon provided 86 to 90% control while dimethenamid applied twice only controlled goosegrass 70%. All other herbicides provided less than 60% control of DNA resistant goosegrass in September. Results suggest that single applications of indaziflam and oxadiazon or sequential applications of dimethenamid have potential to control DNA resistant goosegrass." |
