The results of tests of the potato protection system with chemical preparations of the company “Agrorus & Co” in the conditions of the Moscow region on Favorit and Sante varieties are presented. The results of the tests showed that the use of herbicides reduced the number of perennial weeds by 87,3% and annual weeds by 91,4 %. The prevalence of alternariasis on the date of the last accounting relative to the control (78,8%) decreased by 1,7 times, and the degree of development by 2,7 times, late blight – on the susceptible variety of the tops of Santa almost twice, and the degree of development by 3,4 times. The biological effectiveness against the Colorado beetle of preparations for pre-planting treatment was 96,9-100,0%, and for preparations during the growing season – 99,5-100,0%. The increase in gross and commercial yield on the Favorite variety was 56,3% and 58,2%, respectively, on the Santa variety – 31,4% and 32,8% compared to the control.
