Эффективность комплексной предпосевной обработки фунгицидами и фиторегуляторами в защите разных генотипов ячменя

Abstract

Efficiency of complex presowing treatment of seeds with fungicide vintsit, phytoregulators -emistime C, epibrassinolide and mixes of preparations to protect two grades and isoplasmatic lines of spring barley from mot rot and leaf-blight helminthosporfosis against the natural infectious background was investigated. Phytoregulators interacted with fungicide differently, its toxic action being strengthened depending on a doze, features of preparations and genotypes. The use of vintsit in half-doze together with emistime С did not result in decrease of bioprotective effect of fungicide. The role of a nucleus and cytoplasm in the character of response to influence of preparations used separately and in complex is discussed in the article.
