Test of the Effectiveness of Senduduk Leaf Extract Concentration (Melastoma Malabrhaticum L.) Against Anthracnose Disease in Red Chili Commodities (Capsicum annuum L.)

Abstract

The disease that causes low chili productivity in Indonesia is anthracnose, anthracnose disease caused by the fungus Colletotrichum spp. Efforts to control anthracnose disease are currently still being made using many synthetic pesticides. The use of synthetic pesticides can have a negative impact on the environment. Vegetable functions can be used as another effort to control anthracnose. Plant extracts can be used in anthracnose disease control are Senduduk leaf extracts. This study aims to obtain the concentration of Senduduk plant leaf extract (Melastoma malabathricum L) in inhibiting the growth of Colletotrichum spp. Research is carried out in the field and laboratory. The design used in this research was a complete randomized design (RAL) with 5 treatments of Senduduk leaf extract, namely K0 = 0%, K1 = 3%, K2 = 6%, K3 = 9%, and K4 = 12%. With 3 repetitions. The results showed that Senduduk leaf extract treatment with a concentration of 12% effective could inhibit the growth of Colletotrichum capsici fungus.
