Control of Infection and Sporulation ofBotrytis cinereaon Bean and Tomato by Saprophytic Yeasts

This is the authors' abstract. We don't add key points for this paper.

Saprophytic yeasts were screened for their ability to reduce the sporulation of Botrytis cinerea and the severity of gray mold. One isolate of Rhodotorula glutinis and two isolatcs of Cryptococcus albidus effectively controlled disease on bean and tomato plants. Their ability to reduce the germination of conidia and the severity of rot symptoms on detached leaves and to control the disease on whole plants at calculated concentrations of 750-7,500 cells per square centimeter under growth-room conditions was consistently as effective as the known biological control agent Trichoderma harzianum T39 (unformulated). Glucose and KH 2 PO 4 (0.02 M each) were added to conidial suspensions of B. cinerea to enhance infection
