Abstract

Background

Sorghum is susceptible to weed at its early growth stage. The aim of this efficacy trial was to ensurethat efficacy of chemical Glyphosate-isopropylammonium 41% SL on sorghum weeds control non-selectively before sorghum sowing.

Methods

Thrice experiment was carried out in Humera area in Humera Agricultural Research Center, Semur farm and Desta Berhe farm during rainy growing season of 2019 using sorghum variety i.e. Brhan. Pre and post spray weed count were subjected to efficacy calculation.

Result

New product of herbicide, Glyphosate-isopropylammonium 41% SL (Glpho) at 3.00 lt a.i./ha was shown better performance than the standard check Glymax 48% SL (W/V). Therefore, the new Glpho product could be suggested as an alternative non-selective herbicide before sorghum sowing.
