Title : EVALUATION OF THE EFFICACY OF NEW HERBICIDE FOR CONTROL OF BROADLEAVED WEEDS IN WHEAT UNDER MID HILL CONDITIONS OF HIMACHAL PRADESH

Abstract :

Due to the absence of effective management techniques, weed infestation is one of the main biotic factors affecting wheat output and productivity. Herbicides are a crucial part of agricultural production systems because they are the quickest, cheapest, and most effective way to control weeds. Decrease in the use of herbicides without compromising yields can save production costs and environmental damage. Evaluation of herbicides and their mixtures were studied at the experimental farm of the Department of Agronomy, CSK HPKV, Palampur, to control the broad-leaf weed infestation in wheat. Findings exhibit that among the different herbicide treatments tested Halauxifen methyl Ester + Florasulam + Polyglycol recorded significantly higher growth and yield attributes of wheat which was statistically at par with Halauxifen-methyl + florasulam + carfentrazone + surfactant treatment while significantly lower growth and yield attributes of wheat was recorded in weedy check treatment. Higher yield (straw and grain) and weed control efficiency of wheat was recorded in Halauxifen-methyl + florasulam + carfentrazone + surfactant treatment while lower grain yield, straw yield and weed control efficiency was recorded in weedy check. Hence, highest gross returns (134.3 × 103 INR ha-1), net returns (91.4 × 103 INR ha-1) and B: C ratio (2.13) were obtained from Halauxifen-methyl + florasulam + carfentrazone + surfactant 10.21 + 20 g a.i. ha 1 treatment.
