Results of research on the influence of modern fungicides in single and double application in winter wheat agrocenos in the community of weeds, harmful and beneficial insects, flora topsoil. There was a trend to increase the number of flowering weeds on a variant with double use of fungicides, with favourable effects of mint family plants. Found that the more developed, thick and tall plants with twice the use of fungicides is almost two times more attracted ordinary graminae and wheat aphids, thrips compared to control or with a single application of a fungicide Alto Super. The use of fungicides in crops of winter wheat favors, on the one hand, bring insect species, especially sucking species, but, on the other hand, are more fully involved and entomophagous insects: flies of the family Syrphidae, carnivorous Coccinellidae, parasitic Aphididae. Used during vegetation in the recommended consumption standards fungicides Alto Super and Amistar extra when single and double handling is practically not influenced of the microflora of the soil.
