PROTECTION FROM PESTS OF AGROBIOCENOSIS OF GRAIN-COTTON CROPS

It is known that the areas under winter wheat are being expanded in Uzbekistan. Thus, the number of areas for adjacent crops has also increased. In June-July, corn, sorghum, peanuts, sunflowers, legumes and vegetables are sown on large areas. All of them can be affected by various universal and specific pests. Some of them can be damaged by aphids, spider mites, whiteflies, thrips, rootworms, cotton worms, if no measures are taken against them, a large number are stocked in winter, then next year these areas will turn into a real danger to cotton. Cereal crops ripen relatively earlier, so the harvest also ends early in the months of May-June, then legumes and root crops can be sown. However, early maturing varieties of corn are mainly sown for silage, hay or grain, as well as peanuts. The ripening period of these crops is very short and yield until November. For tall corn plants, various pest control methods are used. A special place among them is occupied by the chemical method. But there are problems when using this method: the tractor cannot drive between fields; manual labor productivity is low. This requires the creation of a system for sowing special crops. According to the above, we conducted this experiment. This article contains points on the creation of a new protection for cotton from major pests; effective use of pheromone traps; the timing of the use of biological methods against the cotton bollworm, the chemical method of control as a last resort and scientifically based timing. In addition, the article shows the dynamics of pest development, harms and methods of dealing with them after cereals in repeated crops.
