Abstract
Three experiments are reported. Simazine, propachlor and nitrofen controlled Digitaria sanguinalis not controlled by atrazine. Propazine controlled Paspalum spp. better than simazine or nitrofen and controlled Eleusine indica and Leptochloa chinensis. Simazine, atrazine and propazine were more effective against Alternanthera spp. and broad-leaved weeds generally than diuron and nitrofen; 2,4-D applied to foliage was also effective. Atrazine and propazine controlled Amaranthus spp. especially A. viridis. Most of the triazines controlled Ageratum conyzoides, Galinsoga parviflora and Stellaria aquatica. Herbicides were rated for weed control in sorghum in the order diuron>simazine>atrazine>propazine>propachlor with pre-em. application and prometryne + simazine = diuron>atrazine >prometryne>2,4-D with post-em. application. Half rates of herbicides mixed with 2,4-D were generally advantageous, especially with post-em. application; atrazine/2,4-D and diuron/2,4-D combinations increased the grain yield by 25% and 63%, respectively. Atrazine was the only herbicide which gave a higher grain yield than hand weeding. Prometryne, propachlor, propazine and simazine reduced the yield by 1-10%, diuron, prometryne + simazine and 2,4-D by 11-20% and nitrofen by 27.5%
