Phytosanitary diseases’ monitoring of breeding crops of winter cereals and limitation of their harmfulness

Abstract

Studies on fungicides’ effect on new varieties and lines of winter triticum-wheatgrass hybrids and winter triticale were conducted in the conditions of the Central zone of the Russian Federation. The results showed that the preparations Alto Super, CE and Falcon, CE effectively cope with the suppression of brown leaf rust on new varieties in the dosages recommended by manufacturers. They allow to reduce the prevalence of brown rust by 15.2-35.6%, the development degree of the disease - by 9.9-18.0%. The spread of septoria decreases by 7.7-8.8%, the intensity of plant damage - by 1.0-2.2%. The use of these preparations allowed to increase crop yields by 1.2-1.7 times compared to the option with no fungicidal treatments.
