Abstract:
The impacts of ready-mix and tank-mix herbicides treatment on weed control in wheat were studied in the field during the Rabi season of 2022-23 at Dev Bhoomi Uttarakhand University, College of Agriculture, Dehradun, Uttarakhand, India. The agronomic replicated field experiment was carried out in a randomized complete block design, having ten treatments, viz. spray of ready-mix herbicide MES + IOD @ 12+2.4 g a.i. ha-1 and SUL + MET @ 25 + 4 g a.i. ha-1, and other spray of tank-mix herbicide SUL + CAR @ 25 + 20 g a.i. ha-1, SUL + (HAL+FLO) @ 25+12.76 g a.i. ha-1, SUL + PYR @ 25+18 g a.i. ha-1, CLO + MET @ 60+4 g a.i. ha-1, CLO + (HAL+FLO) 60+12.76 @ g a.i. ha-1 and CLO + PYR @ 60 +18 @ g a.i. ha-1 and was compared with the weedy check and two-hand weeding (20 and 40 DAS). During the crop growth period, consistently lowest and highest densities of total weed were recorded under 2-HW (20 and 40 DAS) and weed check, respectively. Observation recorded from 30 DAS to 60 DAS showed that the density of total weeds was statistically at par in almost all the herbicidal treatments and was statistically superior in the reduction of total weeds as compared to weed check. Observation recorded at 90 DAS showed that, among the herbicidal treatments, application of SUL+CAR @ 25+20 g a.i. ha-1, CLO+MET @ 60+4 g a.i. ha-1, and CLO+PYR @ 60+18 g a.i. ha-1 recorded significantly the lowest density of total weeds and was second best to 2-HW(20 and 40 DAS). Further, at harvest, 2-HW (20 and 40 DAS) and SUL+CAR @ 25+20 g a.i. ha-1 recorded at a par density of total weeds. The purpose of the research is to evaluate the response of ready-mix and tank-mix herbicides on weed dynamics in wheat and investigate the effect of ready-mix and tank-mix herbicides on the growth and yield of wheat. then calculate the economics of ready-mix and tank-mix herbicides for weed management in wheat. In Weed control, the experiment shows the result was the treatment of SUL+CAR 25 + 20g a.i. ha-1 and CLO+MET 60 + 4 g a.i. ha-1 results in increased crop growth, wheat yield, and improved weed suppression, and crop growth was observed with the treatment on sulfosulfuron + Carfentazole (25 + 20 g/ ha). Results indicated that ready-mix and tank-mix herbicide treatment on weed control in wheat resulted in antagonistic effects on wheat profitability as well as productivity.
