Abstract
The research purpose – to expose the most effective types of rheochrysins of phytogenous and methods of their application at protecting of grain of wheat from the wreckers of panary after-passes. We studied the grain of spring wheat varieties Kinelskoye 59, zoned in the Samara region. Studied the effect of 6 – repellent plant species used in various forms (oil, whole and crushed leaves or flowers, alcohol and aqueous extracts): allspice, mint grass, bay tree, lambsquarters, Sochirca field and marigold), the following biological parameters: free choice of food, the loss of dry matter, development duration lifetime. When feeding beetles small black beetle smallest grain mass loss observed in the presence of essential oil of cloves (86% less than in the control) and the aqueous extract and dried peppermint leaves and flowers of carnation (by 72%). Emergence of small black beetles beetle does not occur on the grain with crushed clove flowers. The death of the granary weevil beetle occurs in the presence of chopped mint (by 17,7% less than in controls). Complex effect of repellents on the granary weevil appeared in samples with crushed clove flowers and leaves of bay leaf. Lowest life expectancy of small black beetles beetle was observed on grain treated with aqueous extract of mint and cloves, which killed 67,2-68,0% beetles. greatest deterrent effect of small black beetles beetle appears if you select write on corn treated with mint essential oil (by 96,2% compared with control) and clove oil (91,6 %). More effective form repellents are crushed leaves and flowers of plants (bay leaf, clove) and peppermint essential oil, compared with clove oil.
