Abstract

Over a 3-year period, pigweed (Amaranthus sp.) was successfully controlled in grain sorghum (Sorghum bicolor (L.) Moench) with preemergence aerial application of 2-chloro-4, 6-bis(isopropylamino)-s-triazine (propazine) and postemergence application of 2-chloro-4-(ethylamino)-6-(isopropylamino)-s-triazine (atrazine) in 4.7 to 47 L/ha of various carriers. Equally good pigweed control was obtained with ground application of the herbicides with as little as 37 L/ha carrier. Liquid formulations of the two herbicides gave results comparable to an 80% wettable powder formulation.
