Colletotrichum orbiculare

Colletotrichum orbiculare is a plant pathogen affecting melons and cucumbers that causes anthracnose, a disease that produces lesions on various parts of cucurbit plants including cucumber, melon, squash, watermelon and pumpkin, especially in rainy, humid and warm weather. It can be transmitted by seed and soil, survive between crops, and spread through feeding cucumber beetles, splashing water, tools and workers. It is managed by rotating cucurbits out of a field for two years, planting resistant cultivars, burning infected crops, controlling weeds carefully, and applying chemical treatments.
