Abstract

Chili is an agricultural commodity with a high economic value. In Indonesia, the supply of red chili has not been able to meet the needs of the communities. One of the biggest factors in decreasing the number of chilies was the attack of anthracnose. Anthracnose is caused by the fungus Colletotrichum capsici. This fungus would infect chili peppers marked by small black spots on the fruit. Then, the fruit would be dry and shrivel or mummy and would fall off. The study aimed to determine the use of extracts of several types of weeds at different temperatures of aquades solvent on the intensity of anthracnose disease, growth, and yield of red chili plants. The study was conducted from February 2021 to June 2021. It was a field experiment study with a Completely Randomized Design (CRD). The treatment consisted of two factors. The first factor consisted of the different types of weeds (bandotan weed, kirinyuh weed, and teki weed), while the second factor consisted of the different temperatures of aquades solvent (normal temperature, 500C temperature, 900C temperature). The observation variables were plant height, fresh healthy fruit weight, number of healthy fruit, number of diseased fruit, the intensity of anthracnose disease, phytotoxicity test, and phytochemical screening test. The extract spraying process was carried out once a week. The weed extract treatment significantly affected the number of diseased fruit and the intensity of anthracnose disease and did not significantly affect the number of healthy fruit, healthy fruit weight, and plant height. The simple extraction with different solvent temperatures did not significantly affect all observed variables. The interaction between the types of extract and the difference in solvent temperature significantly affected the number of diseased fruits. Bandotan extract treated with solvent at room temperature (T1M1) and treated with the solvent temperature of 900C (T1M3) produced the least number of diseased fruits, namely 3.40 fruit/plant and 4.80 fruit/plant.
