Biological Efficiency of Protective Measures for Winter Wheat Crops in the Central Ciscaucasia

Abstract

Recently, the phytosanitary state of winter wheat agrobiocenoses in the Central Ciscaucasia began to deteriorate noticeably. In this regard, the study of new fungicides is of great importance in protecting winter crops from diseases. The paper aims to determine the biological effects of the new fungicide Elatus Ria in winter wheat crops in the weather and climatic conditions of the Central Ciscaucasia. After 21 days, in the variants with the fungicide Elatus Ria with application rates of 0.5 and 0.6 l/ha, high biological efficiency was recorded in winter wheat crops against fungal infection, which, in terms of prevalence and degree of development, depending on the pathogen, was within 97.0–100.0%. The research indicated the reliable protection of winter wheat crops with the fungicide Elatus Ria with the studied consumption rates from pathogenic fungal microflora (Septoria spp., Helmintosporium tritici-repentis, Erysiphe graminis, Fusarium spp., Puccinia recondite). Additionally, the authors proved that the fungicide Elatus Ria has a beneficial effect on plants under extreme conditions of growth (soil and air drought) in the natural climatic conditions of the Central Ciscaucasia.
