BIOLOGICAL EFFICIENCY OF FUNGICIDES IN WINTER WHEAT CROPS AND THEIR INFLUENCE ON CROP YIELD

abstract 1321708080 issue 132 pp. 1035 – 1044 31.10.2017 ru 107
For the production of high quality winter wheat grain, it is necessary to observe the technology of growing the crop and creating optimal conditions for the growth and development of plants. An important role in it is played not only by agrotechnical measures, but also by effective protection of crops from pests. The phytosanitary state of winter wheat sowings has worsened significantly in recent years, however, the degree of damage to crops and the harmfulness of fungal diseases can be significantly reduced, and in some cases completely prevented by treatment of crops with fungicides. The range of fungicides is improved annually by incorporating more effective and less environmentally hazardous preparations. The research is aimed at determining the optimal rates of consumption, the biological effectiveness of new fungicides and assessing their effect on the yield of winter wheat. As a result, it has been established that treatment with Abucus Ultra with a rate of 1.0 l / ha has protective properties, but does not treat plants (72.2%). This further leads to a loss of an average of about 0.5 tons of grain per hectare. Fungicide Akanto Plus in the investigated rates of consumption has good protective and eradicating (healing) properties and with a decrease in the rate of consumption of less loss of yield. Thus, the choice of the preparation and its consumption rate should be based on an understanding of the phytosanitary situation, taking into account the condition of crops and the agroclimatic situation

BIOLOGICAL EFFICIENCY OF PROTECTION OF WINTER WHEAT FROM PHYTOPAGES USING BIOPESTICIDES IN THE SPRING-SUMMER PERIOD OF VEGETATION

abstract 1552001017 issue 155 pp. 233 – 242 31.01.2020 ru 13
The studies were conducted on the biological economic efficiency of biological preparations against pests in the conditions of the training and experimental farm of the Federal State Budget Educational Institution of Higher Education of the Stavropol State Agrarian University in winter wheat crops of the Yuka variety. The effect of triple use of biosecticides Bioslip BV (viable spores of Beauveria bassiana OPB-09 strain) and Bioslip BT (viable spores and thermostable crystalline endotoxin of B. thuringiensis strains) was studied. A tank mixture of Alt-Alf chemical insecticides, CE (alpha-cypermethrin 100 ml / l) and Actara, VDG (thiamethoxam 250 g / kg) was used as a reference. Bioinsecticide Bioslip BV most effectively suppresses cereal aphids: the average biological effectiveness was 78.3%, in relation to harmful turtle and wheat thrips, the effectiveness of the drug was 60.3-68.7%. Bioinsecticide Bioslip BT is effective against the red-breasted drunkard; the average biological effectiveness was 84.2%, in relation to other species - 27.2-44.2%. The efficiency of using a tank mixture of bioinsecticides with half consumption rates was in the range of 23.3-40.7%. The harmfulness of phytophages in winter wheat crops is high, the control yield is lower by 0.556 t / ha compared with chemical treatment. The smallest difference with economic etholone in the variant with three times use of Bioslip BV is 0.09 t / ha
