T. Atajanov gave a lecture on the topic "Innovative fight against sucking and rodent pests in the fields of Khorezm region". It began to be widely used in world agriculture after 1945 with the creation of a number of effective preparations. In the chemical protection method, only pesticides approved by the State Commission and approved by the State Commission are used. Compliance with these measures ensures that pesticides do not remain completely in agricultural products or that their amount does not exceed the permitted level. For each branch of agriculture in Uzbekistan, measures for the use of chemical agents, i.e., the rate of consumption of each drug, the terms of starting and ending processing, and the number of repetitions are defined. There are 2 types of measures involved in chemical protection: prevention and pest control. Preventive measures are carried out before harmful organisms damage plants (seed treatment, application of chemical preparations to the ground along with planting, etc.); the pesticide used for this purpose must maintain its effectiveness for a certain period of time after application. 3.Measures aimed at eliminating the participants are carried out against the pests that have started to damage the plant. For this, it is necessary to carry out the processing in the entire cultivated areas or tree groves at optimal times. For the correct use of chemical protection methods, the number of pests is constantly counted, as well as a forecast of the development and increase of pests and diseases is made, the level of their potential to cause harm is determined, and the effectiveness of protective measures is evaluated. Chemical protection method in places where pests are common. events are held only if there are no other effective protection measures.
