Efficiency of foliage applications of copper fungicides in sowings of winter wheat

Abstract

Aim. To investigate efficiency of row of inorganic fungicides on the basis of copper against the causative agent of farinaceous dew, their influence on the productivity and on content of copper in grain of wheat winter-annual. Methods. Field tests, statistical analysis. Content of copper in grain of wheat was determined by the method of emission Mass spectrometry. Results. High activity of fungicides is shown on the basis oxychloride and sulfate of copper against the causative agent of farinaceous dew. Application of these fungicides gives an opportunity to promote structural indexes and productivity of wheat of winter-annual without the increase of content copper in grain. Conclusions. Preparations on the basis of copper – Kocide 2000, Meteor, XOM are the important components of technologies of feed of wheat winter-annual, especially on soils with subzero content of microelements.
