Abstract

This article discusses the antifungal property of the Gliocladium catenulatum extraction on widespread phytopathogenic fungi of agricultural crops in Northern Kazakhstan as Botrytis cinerea and Fusarium Oxysporum. As a result of studies, this micromycete-antagonist isolated from the root of healthy strawberry Gliocladium catenulatum showed high antifungal activity, supressio zone 35±0.05 mm. It was revealed that Fusarium Oxysporum strains are more sensitive compared to Botrytis cinerea. For example, with optimal dilution of the extract 30 times, on average the suppression zone in Fusarium Oxysporum showed 26±0.03 mm, whereas in Botrytis cinerea 24±0.03 mm.

The optimal condition (nutrient medium, temperature, carbohydrate use, pH medium) for intensive growth and development of Gliocladium catenulatum producer by surface cultivation method was determined.

The aim of the research is to evaluate the fungicidal property of Gliocladium catenulatum against Botrytis cinerea and Fusarium оxysporum and further use this micromycete as a biological preparation against phytopathogenic fungi to increase crop yields.
