This scientific article provides data on the effectiveness of successive application of herbicides against annual and perennial weeds in cotton fields on arable lands plowed with simple and two-sided plows. When the herbicide Samurai (1.5 l/ha) is applied separately, the annual weeds are effectively lost (86.8-90.2%), and have a weak effect on perennials. When Zellek Super (1.0 l/ha) herbicide is used separately, it has a weak effect on annuals (24.0-32.0%), effectively reducing weeds. Both perennial weeds (90.5-93.0%) and perennial weeds are effective when applied in series with Samurai (1.5 l/ha) and Zellek Super (1.0 l/ha) herbicides 88.9 -93.3% loss. Cotton yield will increase by 1.8-5.4 q/ha compared to the control option. Consecutive application of Samurai (1.5 l/ha) and Samurai (1.5 l/ha) and Zellek Super (1.0 l/ha) herbicides against annual and perennial weeds is recommended.
