Determination of Suppression Efficiency of Vermicompost Extracts on Some Aerial Fungal Plant Pathogens

Abstract

The use of vermicompost in agriculture has become increasingly common, especially in organic agriculture. In this research, the suppression efficiency of horse and cattle vermicompost extracts against some aerial fungal plant pathogens (Monilinia laxa, Cytospora leucostoma, Botryosphaeria obtusa, Phomopsis viticola, Alternaria mali, and Botrytis cinerea) that damage fruit trees and are common in fruit production areas, was studied for the first time in our country. %25, %50, %75, and %100 concentrations of horse and cattle extracts were tested against fungal plant isolates. The results were evaluated by two-way ANOVA testing the suppression rates of vermicompost extracts in petri plates. While the best results were found in M. laxa (90,6%), P. viticola (80,2%), A. mali (65,1%) at 100% concentration for horse and cattle vermicomposts respectively, the suppression of B. obtusa (44,7%), C. leucostoma (38,1%), and B. cinerea (35,5%) was found to be lower.
