Abstract

Effects of vermicompost, Effective microorganisms (EM1) and the combination between vercompost and EM1 were applied to manage white rot of onion caused by Sclerotium cepivorum Berk. under greenhouse and field trials at Mallawy Agric. Res. St., Menia Governorate. The recommended fungicide Folicure 25% EC (tebuconazole 25%) was used as comparison. All treatments under investigation either under greenhouse or field conditions reduced the percentage of infection by white rot of onion compared with untreated plants. The combination between vermicompost and EM1 under greenhouse or open field conditions was more effective in reducing the disease more than single treatments. From other hand, all treatments under investigation increased the all assessment parameters i.e., onion bulb yield, plant height, no. of leaves/plant, bulb diameter, fresh and dry bulb weight compared with untreated plants. Vermicompost treatment at the rate of 5 ton/fed combined with EM1 treatment was the best treatment for increasing onion bulb yield more than control and Folicure treatment.
