SPRING WHEAT PROTECTION AGAINST DISEASES IN ZAURALYE (BEHIND THE URALS)

Fungicide treatment of seedlings is the method of prompt response to negative changes in the phytosanitary conditions of agrocoenosis. Their treatments are to be economically and ecologically justified. The aim of the research was to study technological techniques of applying plant growth regulators, biopreparations and fungicides to spring wheat in order to choose the most effective of them, improving phytosanitary conditions of seedlings and increasing crop productivity under Kurgan region conditions. Field experiments were conducted in Central test-field of Kurgan Research Institute of Agriculture in 2004–2013. The objects of research were soft spring wheat cultivars: Omskaya 18 (in 2004–2006), Omskaya 36 (in 2007– 2013). Bare fallow was the precursor. The field experiments conducted showed different efficiency of the preparations of fungicide effect on spring wheat under altering intensity of agrocoenosis damage. Yielding went up by 3.0–18.7 % versus the control. Biological efficiency of the preparations was determined by reacting substance and degree of wheat leaf damage from 46.2 to 97.7 % in the years of epiphytoties and from 10 to 83.5 % under the conditions of moderate progress of leaf-stem infections. The treatment with fungicide preparations is considered unreasonable in the years of depressive manifestation of air-borne and above ground diseases.
