This impressive OMRI Listed biological fungicide is based on a naturally occurring, non-pathogenic saphrophytic fungus known as Unocladium oudemansii (U3 strain). This live spore preparation has been developed as a preventative specifically to control common plant pathogens such as Botrytis cinerea, Sclerotinia sclerotiorum and Monilinia spp.

BotryStop has a unique mode of action in that it aggressively occupies the same ecological space as plant pathogens and will out-compete them for nutrients. This process begins when you apply BotryStop spores to dead and senescent plant debris. Once applied, they will germinate and then colonize the plant debris until further sporulation occurs. Once that happens, the new spores will spread to available space on remaining dead and senescing tissue, depriving the pathogens of their room and board. This thriving colony of Unocladium oudemansii provides protection from pathogens to fruit, blossoms, and plant tissue.

OMRI listed BotryStop poses no threat to living tissue, is non-invasive, is exempt from residue tolerances and has a 4-hour REI and a 0-day PHI. BotryStop makes an exceptional resistance management tool as, due to its mode of action, it is extremely unlikely that resistance to it will develop.

Please note: BotryStop is labelled for use on a wide variety of crops and ornamentals – except in California. There is specific label for California use that is more restrictive. To see either or both of these labels, please go to the Docs tab.
