BotryStop^® WP from BioWorks is now available in California, USA

BioWorks launched BotryStop WP in California on June 28, 2023 and is now registered in all 50 states. BotryStop WP is a newly formulated biological fungicide that delivers superior prevention and control of Botrytis when trialed against other biological and chemical control options. BotryStop WP delivers up to 40% greater efficacy and even more in certain trials when compared with competitive products on a diverse set of crops infected with the disease. For indoor and outdoor use, BotryStop WP in California is registered for use on grapes, strawberries, stone fruits, berries and small fruits, and almonds. The previous formulation of BotryStop will be discontinued 6/28/2023.

BotryStop WP’s active ingredient, Ulocladium oudemansii (U3 Strain), has a unique mode of action (MOA) that prevents and controls Botrytis cinerea, Sclerotinia sclerotiorum, Monilinia spp., Xanthomonas and other foliar pathogens. BotryStop WP outcompetes the pathogens for nutrients released by senescing plant tissue and occupies the same ecological niche that pathogens like Botrytis colonize. Without causing any damage to living, healthy tissue BotryStop WP supports healthier crops. This also makes BotryStop WP an excellent disease-prevention tool that can be used alone or in a spray rotation for resistance management.
