The invention belongs to the technical field of biological control, and relates to application of
Wickerhamomyces anomalus in
postharvest disease control, storage and fresh-keeping of tomatoes. A method comprises the following steps of: activating and culturing
Wickerhamomyces anomalus, performing centrifuging to obtain thalli, diluting the thalli with
sterile water to obtain a
yeast suspension with the concentration of 1*10<8> cells / mL,
punching the surfaces of the tomatoes, injecting the
yeast suspension, and injecting an isopyknic
botrytis cinerea
spore suspension with the concentration of 1*10<5> spores / mL after 2 hours, so as to effectively control the gray mold, or directly and uniformly spraying the
yeast suspension on the surfaces of the tomatoes, and performing natural air-
drying. The purposes of preventing and treating the
postharvest gray mold of the tomatoes, storing and fresh-keeping can be realized; according to the invention,
postharvest gray mold and natural rot of the tomatoes can be effectively controlled, so that the loss caused by postharvest diseases of the tomatoes is reduced; meanwhile, operation is convenient, safe and environment-friendly; and remarkable
economic benefits and
social benefits are achieved.
