Bio-efficacy of tiafenacil 70 WG alone or in combination with adjuvant against mixed weed flora in non-cropped land
Keywords:
Tiafenacil 70 WG, adjuvant, non-cropped land.Abstract
A field experiment consisted of twelve weed control treatments was conducted during kharif 2023 at Palampur to evaluate the bio-efficacy of the tiafenacil 70 WG alone or in combination with adjuvant against mixed weed flora in non-cropped land following Randomized Complete Block Design with three replications that included tiafenacil 70 WG at 100, 150, 200 & 250 g/ha with or without adjuvant, glyphosate 3000 g/ha, paraquat 3000 ml/ha, hand weeding and untreated control. Ageratum conyzoides, Parthenium hysterophorus, Euphorbia hirta, Cynodon dactylon, Commelina benghalensis, Digitaria sanguinalis, Eleusine indica and Cyperus rotundus were the major weed flora in the area. The hand weeding was superior among all the treatments while, in case of herbicides, tiafenacil 70 WG at 250 g/ha with adjuvant and tiafenacil 70 WG at 200 g/ha along with adjuvant were quite effective in reducing total weed count and total dry weight with higher weed control efficiency.
