Abstract

A biocontrol agent including Streptomyces sp. A1022 was formulated into the form of a solid concentrate (SC) to evaluate its effect on anthracnose (Colletotrichum gloeosporioides) of pepper plants and was compared to that of commercial fungicide, azoxystrobin. Percent disease incidence was in the following order: untreated control > azoxystrobin > Streptomyces sp. A1022 SC. The average weight per pepper fruit was higher with Streptomyces sp. A1022 SC than those with azoxystrobin and the untreated control. The root length of the pepper plant postharvest was in the following order: Streptomyces sp. A1022 SC > azoxystrobin > the untreated control. Results showed that the pepper plants were more protected from anthracnose and under better growth conditions with Streptomyces sp. A1022 SC than with azoxystrobin and the untreated control.
