Fruit wounds and marine resources were utilized to screen for potential antagonists to postharvest rot of cherry tomato. Biocontrol activity of a total of 34 yeasts isolates were tested, among which four isolates were selected with the best efficacy in reducing the decay rate of Alternaria Alternata and Botrytis cinerea. One of the marine yeast isolated from East China Sea was identified as Rhodosporidium paludigenum Fell & Tallman, which has not been described previously as a biocontrol agent. The application of R. paludigenum is also effective for other postharvest rot of fruits. Its efficacy declined to a 36% reduction in pear, a 33% reduction in persimmon and an 69% reduction in Chinese jujube after one week of storage.
Keywords:antagonists; cherry tomato; biological control; postharvest; Alternaria. Alternata; Botrytis cinerea; Rhodosporidium paludigenum
