ABSTRACT
Anthracnose disease caused by Colletotrichum capsici is an important disease in chili that can reduce yield of 60- 100%. Utilization of Bacillus toyonensis strain AGBE1.2.TL in the formulation is an alternative control that is cheap and environmentally friendly. The aim of the study was to obtain the best organic waste-based formulation of Bacillus toyonensis strain AGBE1.2.TL for controlling Colletotrichum capsici and increasing chili growth. This research is experimental using RAL which consists of 12 treatments and 3 replications. The treatment consisted of a combination of carrier materials consisting of organic waste sugarcane bagasse, rice straw and bran, fungicides and controls. The introduction of each formula on the seeds and roots of chili seedlings aged 21 days by soaking for 15 minutes. Colletotrichum capsici was inoculated on chili 72 days old. The results showed that the best Bacillus toyonensis AGBE1.2.TL formula for controlling Colletotrichum capsici and increasing chili growth was the formula JP+AT, D+JP, and D+AT for 6 weeks storage.
