UTILITY OF CLOMAZONE FOR ANNUAL GRASS AND BROADLEAF WEED-CONTROL IN PEANUT (ARACHIS-HYPOGAEA)

Field experiments conducted in 1988 and 1989 evaluated clomazone alone and in a systems approach for weed control in peanut. Clomazone PPI a t 0.8 kg ai/ha controlled common ragweed, prickly sida, spurred anoda, and tropic croton better than ethalfluralin and/or metolachlor applie d PPI. POST application of acifluorfen plus bentazon was not needed to control these weeds when clomazone was used. Acifluorfen plus bentazo n improved control of these weeds when clomazone was not used and gene rally were necessary to obtain peanut yields regardless of the soil-ap plied herbicides. Alachlor PRE did not improve clomazone control of an y weed species evaluated. Fall panicum and large crabgrass control was similar with clomazone or clomazone plus ethalfluralin.
