Reduction of inocula and control of white rot disease in onion and garlic crops by repeated soil applications with sclerotial germination stimulants.

The effect of soil-applied crop products on the viability and the incidence of white rot in subsequent onion and garlic crops were evaluated in this work. The tested products were onion powder, garlic powder, onion oil, garlic oil and waste (onion and garlic) that are described as sclerotial germination stimulants. Under conditions, data revealed that more than 80% of the sclerotia died in the soil treated with sclerotial germination stimulants.
