USA - New formulation of Botrystop^® from Bioworks outperforms existing control options for Botrytis protection

BioWorks launched BotryStop WP, a newly formulated biological fungicide that delivers superior prevention and control of Botrytis when trialed against other biological and chemical control options. BotryStop WP delivered 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 was developed specifically to address Botrytis in ornamental, nursery, food and medicinal plants.

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.

Trial Results

The attached white paper details extensive third-party, independent trial results of BotryStop WP. A few of the data points summarized:

• BOTRYTIS ON RASPBERRIES WHEN TREATED WITH BOTRYSTOP WP

• Trials carried out on ″Meeker″ raspberry, Lynden WA; AgroSci Agriculture Consulting.

• Botrytis-related raspberry fruit rot was 50% lower in BotryStop WP-treated plants than in those treated with Captan 50WP

• BotryStop WP delivered 8% more marketable yield than Captan 50WP

• BOTRYTIS ON POINTSETTIAS WHEN TREATED WITH BOTRYSTOP WP

• Trial conducted by M.K. Hausbeck and B.R. Harlan, Michigan State University.

• Poinsettia bract infection levels were up to 55% lower on plants treated with BotryStop WP, significantly better than competing biopesticide treatments and statistically the same as that provided by the chemical standard Broadform.

• BOTRYTIS ON BLUEBERRIES WHEN TREATED WITH BOTRYSTOP WP

• Trial conducted on ″Berkeley″ blueberry bushes, Burlington WA; AgroSci Agriculture Consulting.

• Botrytis-related fruit rot was 27% lower in blueberries harvested from BotryStop WP-treated bushes than from those treated with Captan 50WP

• BotryStop WP delivered 2% more marketable yield than Captan 50WP.
