Abstract

See also WA 28, 44 and 3960. Five dinitroaniline herbicides were applied post-em. in maize and sorghum at the spike, 6-inch and 18-inch high stages and incorporated by rolling cultivators or A-blade cultivators. It was rapidly recognized that weeds had to be controlled either culturally or chemically until the post-em. application was made and that cultivation is necessary to cover the brace roots of the crop with untreated soil before herbicide application. When herbicides were incorporated in crops at least 6 inches high no damage occurred from the standard rates normally used in cotton. Barnyardgrass [Echinochloa crus-galli] and crabgrass [Digitaria spp.] showed >90% control. When sorghum was sown as a rotational crop the following season, no toxic effects occurred from soil residues of any of the herbicides tested. Prowl [pendimethalin] and Treflan [trifluralin] reduced the water consumption of a maize crop by 40% without affecting the yield and saved $24/acre in irrigation costs
