Environmental influences on biological control of white mold (Sclerotinia sclerotiorum) and grey mold (Botrytis cinerea) of bean.

摘要

The effect of the environment on biological control of white mold (Sclerotinia sclerotiorum) and grey mold (Botrytis cinerea) of bean was evaluated. Propagules of Alternaria alternata, Epicoccum purpurascens, Drechslera sp., Trichoderma viride, Gliocladium roseum, Myrothecium verrucaria, and a pink yeast were co-inoculated onto sterilized bean petals with spores of either S. sclerotinia or B. cinerea. The petals were placed onto leaves of 2 week-old bean seedlings and incubated in the environmental chambers at all combinations of 90, 95 and 100% relative humidity and 20
