Comparative Efficacy of Weedicides for Control of Broad Leaf Weeds in Wheat (Triticum aestivum L.) Crop under Thal Irrigated Areas

Abstract

The experiments were carried out to evaluate the comparative efficacy of different post-emergence weedicides on weeds in wheat crop at Adaptive Research Farm Karor, Distt. Layyah and at farmer’s field a.i. Chak No. 116/TDA, tehsil Karor, Distt. Layyah during Rabi crop season 2022-23 under irrigated conditions. The experiments were laid out in randomized complete block design (RBCD) with three replications. Four different herbicides were applied as post-emergence treatments viz. Buctril Super 60 % EC (Bromoxynil + MCPA) @ 1125 ml ha^-1_, Bromoxynil 40 % EC @1250 ml ha^-1_, Findus Extra 60 WG (Mesosulfuron-Methyl + Iodosulfuron-Methyl-Sodium) @ 240 g ha^-1 and Clean wave (Imino Pyralid + Fluroxyber) @ 800 ml ha^-1. An untreated control was also included in the trials.  All herbicides decrease the weeds population over control up to nine days in both locations and maximum grain yield 4533.35 kg ha^-1 and 4635.50 kg ha^-1 were  produced in Adaptive Research Farm Karor, and at farmer’s field a.i. Chak No. 116/TDA, Tehsil Karor, Distt Layyah respectively, where Buctril Super 60 % EC (Bromoxynil + MCPA) @ 1125 ml ha^-1 was applied. Therefore, it is recommended that Buctril Super 60 % EC (Bromoxynil + MCPA) may be applied @ 1125 ml ha^-1 for offering the control of broad leaves weeds and increase grain yield of wheat.
