Efficacy of Different Formulation of Glyphosate Herbicide on Sorghum Weeds

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.

Application of soil herbicides in gardening to improve fruit production

“…Being highly effective, these herbicides, at the same time, pose a danger to fruit and berry crops; when settling on the leaf surface, their phytotoxic effect can persist for two years (Rico et al, 2007;Greer, 2022). The disadvantage of glyphosate products is that they penetrate weeds only upon direct contact of their working solution with the vegetative part of the weeds (Fisseha et al, 2021). For this reason, the study of the possibility of using herbicides of various mechanisms and periods of action is a very important issue in improving protective measures in orchards.…”
