Various Applications of Active Materials Trichoderma sp. RC 3 Isolate for Antracnosa Disease Control Caused by Colletotrichum gloeosporoides In Chilli

Research on using various active ingredients Trichoderma sp RC3 isolates for controlling Anthraxosa caused by C. gloeosporioides on chili was conducted in the phytopathology laboratory and wirehouse, the Agriculture Faculty, Universitas Andalas from August to December 2016. This study aimed to obtain the best active ingredients from Trichoderma sp. RC3 isolates to control anthracnose diseases caused by C. gloesporoides in chilies. The research used a Randomized Block Design (RBD) with four treatments and three replications, each repetition consisting of 9 chilies. The treatments used were control (sterile aquadest/ without isolates), administration of liquid culture, conidia suspension, and filtrate from Trichoderma sp. RC3 isolate. The variables observed were the incubation period, fruit attacked percentage, and anthracnose disease intensity in chilies. The results showed that the active ingredient was a filtrate containing secondary metabolites from Trichoderma sp. RC3 isolate was the best treatment with an effective disease intensity of 58.45%, the percentage of fruit attacked by 44.45%, and was able to slow the appearance of the first symptoms (incubation period) for 13 day
