The article presents data on weed seed penetration through water and the amount of weed seeds found in the soil of the area where previous crops were cultivated in the cotton:grain rotation system in the conditions of the soils prone to salinity of the Syrdarya region. On the basis of the conducted research, when increasing the effectiveness of chemical control measures against annual and perennial weeds in the fields, the number of annual and perennial weeds is 85.8Up to 79.4%, and 85.395.2% reduction was found when Zellek super herbicide was applied at the rate of 1.0 l/ha in the period of cotton combing. The durations and rates of herbicides used against weeds in the cotton field had a positive effect on yield: 2.3 t/ha when herbicide was applied with seeding, 5.4 t/ha when herbicide was applied with seeding and combing, and weed control at the end of the effective period. it was stated that 1.4 tons/ha of additional yield was obtained as a result of the visit.
