Abstract

The ways of phytosanitary regulation of spring wheat cultivation under minimal technology in the conditions of high specialization of grain production, are limited. The results of the study showed that the sowing time and the precursors of spring wheat can affect the density of settlement of crops by harmful insects. The sowing time and the initial spring wheat can may affect to the density of settlement of crops by harmful insects. Phyllotreta vittula and Apamea anceps distributed on wheat crops after May 22 live in numbers below the economic thresholds of damage, and it cause a danger for early crops. At the time of sowing to the end of the optimal and later the plants are less damaged by the Mayettiola destructor. In Haplothrips tritici, the differences in the direction of decline in late sowing periods are noted only in adults. Delays with sowing, especially in wet years, lead to an increase in the
severity of the Oscinella pusilla. Improving the phytosanitary conditions for pests is facilitated by the placement of wheat after steam, pea, oats, rapeseed. However, one should take into account the significant role of precipitation during the vegetation
period, under the influence of which the number of pests changes significantly. In the drought conditions, the number of Phyllotreta vittula, Haplothrips tritici, Acrididae sp. increases in the crops, while in the humid conditions, Mayettiola destructor and Oscinella pusilla, Aphis sp
