Anthracnose disease (Colletotrichum capsici) is one of the main problem in the cultivation of chili. This study was aimed to discover about the extract of leaf extract of cattapa (Terminalia catappa L) and leaf extract of derris (Derris elliptica) against the growth of Colletotrichum capsici causes anthracnosis in chilli. The study was conducted at the Mycology Laboratory of Institute Vegetables Research Indonesia, on July - September 2018. The study used a randomized design complete (CRD) with nine treatments and three replications. The treatment consisted of: leaf extract of derris (0.5%; 1.0%; 1.5%; 2.0%), leaf extract of cattapa (0.5%; 1.0%; 1.5%; 2.0%), and control (without treatment). The result showed that the leaf extract of derris more effective to suppress the conidial production of C. capsici. Development of colonies diameter leaf extract of derris was relatively smaller (3.24-4.31 cm), while for the treatment of leaf extract of cattapa showed larger colony size (6.02-6.82 cm).
