Abstract

The decline in chili production in Indonesia is partly caused by anthracnose disease, which can result in significant yield losses. Controlling anthracnose disease is crucial to optimizing chili productivity. This study aims to determine the inhibitory effect of turmeric rhizome exudates on the growth of Colletotrichum sp., as turmeric rhizome exudates are suspected to inhibit the growth of this fungus, the causative agent of anthracnose in curly red chili (Capsicum annuum). The exudates were prepared by uprooting one-month-old turmeric plants. The roots were washed under running water and aerated for 12 hours. The resulting liquid was filtered using Whatman No. 1 filter paper and further filtered through a PVDF syringe filter (0.2 µm). The exudate samples were then stored at 4 °C until use. The research was conducted in the Plant Pathology Laboratory, Plant Protection Study Program, Department of Plant Pests and Diseases, Faculty of Agriculture, Sriwijaya University, Indralaya Selatan District, Ogan Ilir Regency, South Sumatra. This study took place from July to October 2024. The treatments involved two concentrations of exudates, namely 1.25% and 5%. The results revealed that turmeric rhizome exudates did not significantly inhibit the growth of Colletotrichum sp.; instead, the concentrations of 1.25% and 5% even increased the growth rate of the fungus. Further research is recommended to test higher concentrations or specific active components of turmeric to evaluate their potential inhibitory effects on Colletotrichum sp.
