FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to the protection of winter wheat crops. Method of controlling septoria blight in winter wheat involves preparing a working solution of preparations of propiconazole, azoxystrobin, sulphonylurea derivatives and water by continuous mixing in the following ratio (wt.%): propiconazole 0.15, azoxystrobin 0.1, sulphonylurea derivatives 0.05, water – the rest. Then, winter wheat crops are sprayed once with the ready working solution in the phase of flag leaf appearance – beginning of ear formation at air temperature of 15-20 °C, relative humidity 70% in the morning at wind speed of less than 4-5 m/s and application rate of 300 l/ha of working solution. At the same time the working solution should be subjected to constant mixing during spraying and its temperature should be 15-24 °C.

EFFECT: proposed method of controlling winter wheat septoria blight extends the range of winter wheat protection agents, as well as provides high efficiency of controlling septoria blight pathogens.
