FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular, to protection of winter wheat crops against causative agent of septoria blight. Method of controlling winter wheat septoria blight includes preparing a solution of a working fluid consisting of 3 l of the preparation Psevdobacterin-2, L, diluted in 250 l of water, spraying of winter wheat in the tillering phase – the beginning of stem elongation – in the morning and evening hours at a temperature of +10 °C to +25 °C. Further, a working solution of propiconazole, azoxystrobin and water is prepared by continuous mixing in the following ratio, wt.%: propiconazole 0.15, azoxystrobin 0.1, water – balance, and ready working solution is once sprayed with winter wheat crops in phase of appearance of flag leaf – beginning of earing at air temperature from +15 to +20 °C, relative air humidity of 70% in the morning at a wind speed of less than 4-5 m/s and the application rate of 300 l/ha of the working solution.

EFFECT: proposed method of controlling winter wheat septoria blight widens the range of means of protecting winter wheat, reduces consumption of pesticide preparations, increases yield, has therapeutic and stimulating effect.
