Расширение спектра применения биофунгицида gliocladin-sc на основе гриба Triсhoderma для защиты черешни от монилиоза и кукурузы от фузариоза

Abstract

Studies were carried out to extend the biofungicide Gliocladin-SC range of action. The results of field studies of the product’s biological efficacy in reducing the development of cherry fruit rot and fusarium cob rot of sweet corn are presented. Two treatments of the cherry variety Krupnoplodnyi with 1,0% Gliocladin-SC at the application rate of 8-10 l/ha yielded 91,8% biological efficacy in suppressing the pathogen Monilia cinerea. One treatment of the orchard seven days before harvesting resulted in 88,0% efficiency. In the Porumbeni-252 sweet corn hybrid, the effect of pre-sowing seed treatment with the application rate of 1l/t against fusarium rot was determined. Studies were carried out on natural and artificial infection backgrounds. The biological efficacy in re-ducing the development of fusariosis on the natural and infectious background was 71,9% and 66,7%, respectively.
