Effects of Compost Tea Making from Differently Treated Compost on Plant Disease Control

Antifungal activity of compost teas was evaluated in vitro and in vivo experiments. In vitro test, fourteen compost teas were produced using five different composts and through six different methods for compost tea production. Eleven pathogenic fungi were used as indicators of antifungal activity of compost teas. In vivo test, one of the compost teas used in vitro test was sprayed to cucumber leaves which were infected with powdery mildew in order to evaluate antifungal activity of compost tea. From the results of the tests, it was found that all compost teas used this study showed antifungal activity and the proper application of compost teas against pathogenic fungi for obtaining optimal effects was important to know.
