In this study, the effect of fludioxonil on morphological and physiological characteristics of Sclerotinia sclerotiorum has been investigated. The results indicated that fludioxonil had a strong inhibition on mycelia growth of S. sclerotiorum. After fludioxonil treatment, cell membrane permeability, glycerol content, POD and PAL activity increased markedly, but oxalate and EPS content significantly decreased. The protective and curative test of fludioxonil suggested that protective effect was better than curative either on leaves or on stems of oilseed rape. These results will increase our understanding of action mechanism of fludioxonil against S. sclerotiorum.
