Efficacy and identification of beneficial bacteria to control Colletotrichum capsici caused anthracnose of chili

Abstract

            All of the 121 isolates of beneficial bacteria were screened from 20 samples of chili. The isolates were divided into 7 groups according to the characteristics of the colonies grown on nutrient glucose agar. The efficacy of beneficial bacteria against anthracnose disease by dual culture method on potato dextrose agar (PDA) were investigated and arranged by a completely randomized design. The bacterial isolates of TU089, TU101, and TU121 were found to be effective in inhibiting the growth of C. capsici strain P-TU008 with 85.55, 78.33, and 88.33% inhibited, respectively, which was better than chemical reagent when compared with agrochemical carbendazim (36.66%). The classification of all 3 isolates by morphological, physiological, and biochemical characteristics by compared with Bergey's Manual of Determinative Bacteriology. The result revealed that bacteria isolate TU089, TU101, and TU121 were similar to Bacillus subtilis, B. Licheniformis, and B. megaterium respectively.
