Capability of Three Yeast Species in Suppressing Green Mold (Penicillium Digitatum) on Siam Citrus Fruit (Citrus Nobilis)

Green mold is one of the main diseases in citrus fruits caused by Penicillium digitatum . One managements that can be used to control this disease using yeasts as antagonistic agents. The objective study was evaluate ability yeast suppress P. siam ( Citrus nobilis Lour.). conducted a completely randomized design. treatments were application yeast, consisting Aureobasidium pullulans isolate Dmg 11 DEP, Rhodotorula minuta 16 BE, Candida tropicalis Lm 13 fungicide benomyl, and control. results showed A. C. R. BE able growth vitro on dual culture method, with suppression levels ranged from 14.64%-21.02%. greatest BE. formation volatile compounds test 14.51%-34%, highest Application fruit reduce pathogen’s growth, suppressions 28.87% 68.72%. suppression.
