According to the results of the study conducted in this article, the application of the herbicide Kataryus bereke at a rate of 0.5 l/ha against annual weeds in rice crops led to the destruction of weeds, the biological efficiency was 94.9% compared to annual cereal weeds. In the experiment, when using the herbicide Kataryus bereke at a rate of 0.5 l/ha, the yield of rice grain was 1.14 tonns higher than the control in the Tashkent region. Taking into account the biological efficiency of the herbicide Kataryus bereke , it is recommended to use 0.5 l/ha against annual cereal weeds in rice crops. It is recommended to carry out tillage work when weeds have developed 3-4 leaves in wet soil.
