Abstract

EFFICIENCY OF THE APPLICATION OF FUNGICIDES AND THE PREPARATION OF TRICHODERMA IN A COMPLEX WITH A CROP ROTATION IN THE POTATO DISEASES CONTROL

Rakhimov Uchkun Khamraevich*

ABSTRACT

The article notes that in the Tashkent region there is a wide prevalence of diseases of late blight and rhizoctonia stem canker of potatoes, as a result of which the growth and development of potatoes, as well as yield, decrease. Treatment of seed potato tubers against these diseases before sowing with Acc-Forte (Tiram 800 g/t) preparations is 80% WP, - 2.5 kg/t and Vitavax 75% WP, at a dose of 2.5 kg/t, the biological effectiveness ranged from 91.0% to 96.0%. Also, data are presented on the biological effectiveness of the application of the introduction of Trichoderma into the soil and the change in crop rotation in the fields of the experimental site of the Tashkent State Agrarian University against fusarium wilt of potato and eggplant. On the basis of the data obtained, crop rotation and the introduction of the antagonist fungus Trichoderma into the soil at the rate of 100-120 kg/ha have a positive effect on the susceptibility of potato plants to fusarium wilt. The smallest susceptibility to fusarium wilt on potatoes and the highest biological effectiveness were observed in the variant where cereals and onions were used as potato previous crops.
