| Abstract/Contents: | "Field studies were initiated in 2001, and repeated in 2002, to determine the effect of clethodim, sethoxydim, and halosulfuron application timing on centipedegrass seedhead suppression, seed yield, and seed germination. Clethodim, sethoxydim, and halosulfuron were applied at 0.25, 0.28, 0.06 lb. ai/A, respectively. Herbicide applications were made at -4, -2, 0, 2, and 4 weeks post seedhead emergence (WPS) in each year. Seedhead suppression varied in severity each year; however, suppression was greatest when clethodim or sethoxydim was applied 0 or 2WPS. Halosulfuron had no affect on seedhead emergence in either year. Likewise, halosulfuron did not reduce seed yield at any treatment timing. Clethodim reduced seed yield between 22 and 44% at all treatment timings. The pattern of yield reduction from sethoxydim was similar to that of clethodim, however, yield reduction for sethoxydim ranged between 7 and 48% for all application timings. The greatest reduction in seed yield occurred when clethodim or sethoxydim were applied 2WPS. Seed germination was not affected by halosulfuron and sethoxydim at any application timing. Clethodim, when applied at 2 or 4 WPS, decreased seed germination by 17 and 20%, respectively." |
