BotryStop® WP

OMRI Listed, Wettable Powder Formulation that Does Not Require Refrigeration

BotryStop WP is an organic biological fungicide formulated as a wettable powder, utilizing the naturally occurring, non-pathogenic saprophytic fungus Ulocladium oudemansii (U3 strain). This live spore preparation is specially developed to prevent and control common plant pathogens such as Botrytis cinerea, Sclerotinia sclerotiorum, and Monilinia spp.

Unique Mode of Action:

BotryStop WP works by aggressively occupying the same ecological niche as plant pathogens, out-competing them for nutrients. Upon application, the spores germinate and colonize dead and senescent plant debris, preventing pathogens from accessing the resources they need. This thriving colony of Ulocladium oudemansii protects fruit, blossoms, and plant tissue from infection.
