Black root rot of cucurbits


Phomopsis sclerotioides is a plant pathogen infecting cucurbits, causing black root rot of cucurbits.

Life cycle and appearance of Black root rot of cucurbits

Phomopsis sclerotioides survives in the soil and is a strong saprophytic competitor, which means it can rapidly colonize ‘clean’ or sterilized soil and substrate. It aggregates, so disinfection needs to be applied thoroughly and evenly. Phomopsis sclerotioides forms sclerotia which can survive adverse conditions for years in the soil, but little else is known about the life cycle. The fungus is dispersed by water, air and soil particles.
