Abstract
Sorghum is susceptible to weed competition at its early stage of growth. The aim of this efficacy trial was to ensure that candidate chemical AgroSuper verification on a selective and effective control of broad leaf weed on Sorghum, after sorghum germination. RCBD with three replication experiment was carried out in Humera area in Humera Agricultural Research Center and Desta Berhe farm during 2019 rainy growing season using sorghum variety called Brhan. Pre and post spray weed count were subjected to efficacy calculation. Finally, new product of herbicide, AgroSuper (2, 4-D dimethyl amine salt 720G/L SL) 1.5 liter using 200-liter water solution per hectare was shown better performance than the standard check Aura 72SL. Therefore, the new AgroSuper could be suggested as an alternative selective herbicide during post-emergency to kill broad leaf weeds of sorghum.
