Abstract
Giant pigweed (Trianthema portulacastrum) infesting sorghum was controlled at the seedling stage by atrazine at 0.14 kg/ha, but plants 5 cm in diam. required a rate of 1.12 kg. Control of T. portulacastrum did not increase the yield of sorghum grain. Sesbania pea (Sesbania cannabina) was susceptible to 2,4-D at 0.56 kg/ha and atrazine at 2.24 kg post-em. Control of S. cannabina resulted in a yield increase in one experiment. Fierce thornapple (Datura ferox) was controlled by atrazine applied post-em. at 1.12 kg/ha, 2,4-D at 0.56 kg and Tordon 50-D (tri-isopropanolamine salts of picloram 50 g/litre + 2,4-D 200 g/litre) at 0.7 litres product. The atrazine and Tordon 50-D treatment also gave residual control of D. ferox plants which germinated later and the sorghum grain yield was increased
