Abstract

Pests compete with field crops for essential growth requirements, primarily weeds, which cause significant damage and losses in growth and grain production if left uncontrolled. A field experiment was carried out during the winter season 2024-25 at the Research Stations of the Faculty of Agricultural Engineering Sciences/ Baghdad University/ Jadriya, to know the effect of Herbicides Atlantes, Navigator  and Limitless and different concentrations in the accompanying Weed and the impact on the yield and its components for the wheat crop (Bhoth 22) in order to reduce environmental pollution and achieve the goals of sustainable development, The experiment was conducted in a randomized complete block design with three replications. Weed control treatments included various concentrations of Atlantes, Navigator, and Limitless applied with different water volumes, along with weed-free and weedy check plots for comparison. The superiority of the treatment Navigator 2. 500 L/h reduced the number of weeds (14 plants/m2) and their dry weights (31.67 g) and improved the growth characteristics of wheat plants, achieving the highest weight of 1000 grains (43.38 g), grain yield (2.53T/h), and the best index of weeds (15.79%), which confirms the effective role of herbicides at different concentrations and diffusers in eliminating the weeds accompanying the wheat crop.
