APPLICATION OF EXTRASOL ON SOFT WHEAT IN THE CONDITIONS OF KOSTANAI REGION

Abstract

Studies have been carried out to determine the increase in the resistance of soft wheat variety Omskaya-36 to diseases from the use of the microbiological preparation Extrasol: 2020 - Kostanay district, I-II natural-climatic zone; southern chernozem, heavy loamy, soil solution reaction pH - 8.3, humus content 3.3%; 2022 - Karabalyk district, I-II natural and climatic zone; ordinary chernozem soil solution pH - 7.2, humus content 3.5%. To determine the effectiveness of the microbiological preparation Extrasol on the restraint of the spread and development of diseases, field plots were selected with annual sowing of spring wheat (monoculture).

It was determined that the use of the microbiological preparation Extrasol reduced the suppression of the most common diseases in the conditions of the Kostanay region on spring wheat, and timely treatment made it possible to block the development of pathogenic diseases, which ensured the further development of plants.
