BioWorks Launches New Biofungicide for Botrytis Control

Primula acaulis, Botrytis, Disease, Griffin Greenhouse SuppliesBioWorks has launched BotryStop, a new organic biological fungicide developed for the control of pathogens such as Botrytis cinerea, Sclerotinia sclerotiorum, and Monilinia spp. in several crops, including ornamentals.

BotryStop is based on the unique naturally occurring nonpathogenic saprophytic fungal strain Ulocladium oudemansii (U3 Strain) which provides protection to blossoms, fruit, and plant tissue.


BotryStop comes in a water-dispersible granular formulation, is compatible with many chemical inputs, and is exempt from residue tolerances. It has a four-hour re-entry interval and a zero-day preharvest interval, and is designed to be an excellent tool for resistance management.

“The BioWorks team is excited to offer another OMRI-listed biofungicide that is safe, effective, and proven,” says Jeff Distasio, National Sales Manager for BioWorks. “With solid trial data on crops such as grapes, strawberries, lettuce, and stone fruits, BotryStop will be another tool in our disease control portfolio that customers can use in both the agriculture and horticulture sectors.”
