Agrotechnical measures and crop rotation also do not ensure complete eradication of weeds. Therefore, it is necessary to use herbicides. Mapping by type and quantity of weeds grown among agricultural crops should be carried out in all crop rotation fields and herbicides should be applied on this basis, i.e. it is important to choose one or another herbicide based on the study of the composition and amount of weeds grown in fields. In the cultivation of corn in Uzbekistan, first of all, it should be aimed at obtaining high yields from its grain. To do this, it is necessary to use all available agro-technical measures. In modern intensive farming, weed control, which is common among agricultural crops, is a key measure.
