Effect of Different Combinations of Herbicides on Wheat Crop and Lolium Weed

Abstract

In this investigation, which took place during the winter agricultural season of 2021-2022 in one of the fields located in the Al-Hindiya District of the Holy Karbala Governorate, the purpose was to investigate the effect of various combinations of herbicides on the development and yield characteristics of wheat as well as a few weeds belonging to the genus Lolium. The experiment was conducted out using a randomized complete block design with three replications and a factor One. This resulted in 11 different combinations of herbicides being tested, including Chevalier, Pallas, Tobic, and Axial. After sixty and ninety days, measurements were taken of the weed, and measurements of the wheat were taken at the end of the growing season. According to the findings, the combination of Chevalier, Pallas, Tobik, and Axial performed exceptionally well in reducing the majority of weed traits, including plant height, chlorophyll index, weed density, and weed dry weight. Decrease of effectiveness of different combinations of Chevalier, Pallas, Topic and Axial herbicides on Lolium weeds. Inhibition of wheat yield and growth when using combinations Chevalier +Pallas+ Topic Axial + and Chevalier +Pallas+ Topic.
