Sclerotium is a major disease of orchids, rapid development, rapid spread, under normal circumstances difficult to cure, often the basin destroyed, orchids is a big disaster. Sclerotinia sclerotiorum is a white mycelium, parasitic on the base of the leaves and pseudobulb. More in the moldy rainy season, the hot season and the substrate more acidic environment.
