Abstract
(1) Anthracnose caused by Colletotrichum damages crops, ornamentals, and forest trees severely, resulting in enormous economic losses to agricultural and forestry systems. Overusing traditional chemical fungicides leads to fungicide resistance, environmental pollution, and potential risks to public health. Therefore, priorities should be given to developing efficient and environmentally friendly approaches to phytopathogens management, including anthracnose. (2) In this study, the antifungal activity of botanical derivative polysubstituted cyclic 1,2-diketones (FPL001) against C. gloeosporioides was examined. (3) FPL001 significantly inhibited the vegetative growth of C. gloeosporioides with an EC50 of 160.23 µg/mL. When the concentration of FPL001 reached 30 µg/mL, the conidial germination and appressorium formation of C. gloeosporioides were completely inhibited. FPL001 also significantly suppressed the invasive hyphae development and plant infection of C. gloeosporioides. FPL001 did not exhibit toxicity to model organisms such as alfalfa and silkworm larvae. (4) These results indicate that compound FPL001 is a potential and efficient agent for green control of C. gloeosporioides.
