Abstract

A field experiment was conducted during kharif 2019 at the Research Farm of Department of Agronomy, College of Agriculture CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the bio efficacy of new herbicide for managing weeds in undulating pasture land pockets. The experiment was laid out in Randomised Block Design with three replications, and consisted of seven weed control treatments including GOD H007 at 860, 882 and 903 g/ha, pyrithiobac sodium 62.5 g/ha, glyphosate 820 g/ha, hand weeding and a weedy check. Application of this new herbicide combination product GOD H007 903 g/ha though remaining statistically alike with glyphosate 820 g/ha, resulted in significantly lowest total weed density and total weed dry matter at all the stages of observation except that at 30 days after spray (DAS) at which hand weeding proved to be a superior treatment. These three treatments interventions also recorded higher weed control efficiency. However, significantly highest fresh and dry herbage yield at 60 DAS was recorded with the application of pyrithiobac sodium 62.5 g/ha. Application of this new herbicide GOD H007 903 g/ha showed promise to be effective for managing weeds in pasture land.

Abstract

A field experiment was conducted during kharif 2019 at the Research Farm of Department of Agronomy, CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, to study the efficacy of new herbicide combination product GOD H007 (containing glyphosate 40% and pyrithiobac sodium 3%) for managing weeds in grasslands. The experiment was laid out in Randomised Block Design with three replications, and consisted of seven weed control treatments viz., GOD H007 at 860, 882 and 903 g/ha, pyrithiobac sodium 62.5 g/ha, glyphosate 820 g/ha, hand weeding and a weedy check. Application of this new herbicide combination product GOD H007 903 g/ha though remaining statistically alike with glyphosate 820 g/ha, resulted in significantly lowest total weed density and total weed dry matter at all the stages of observation except that at 30 days after spray (DAS) at which hand weeding proved to be a superior treatment. These three treatments also recorded higher weed control efficiency. However, significantly highest fresh and dry herbage yield at 60 DAS was recorded with the application of pyrithiobac sodium 62.5 g/ha. Application of this new herbicide GOD H007 903 g/ha showed promise to be effective for managing weeds in grassland.
