BROADLEAF WEED-CONTROL IN SOYBEAN (GLYCINE-MAX) WITH CHLORIMURON PLUSACIFLUORFEN OR THIFENSULFURON MIXTURES

Chlorimuron applied alone and in combination with acifluorfen or thife nsulfuron was evaluated for POST control of common lambsquarters, comm on ragweed, common cocklebur, and a mixture of pitted, ivyleaf, entire leaf, and tall morningglory in soybean. Common cocklebur control was s imilar with thifensulfuron at 3 and 4 g ae ha-1 and with chlorimuron a t 7 and 9 g ae ha-1. Common ragweed and morningglory control was great er with chlorimuron while common lambsquarters control was greater wit h thifensulfuron. Control of all species was good with combinations of chlorimuron at 7 g ha-1 plus thifensulfuron at 2 g ha-1 or acifluorfe n at 140 g ae ha-1 and similar to or greater than the control with chl orimuron at 9 g ha-1. Soybean yields with all POST herbicide treatment s were equivalent to that of the weed-free check.
