BotryStopTM
Biological Organic Fungicide

EPA REGISTERED & OMRI Listed

BotryStop Bioogical Organic Fungicide BotryStop is an effective biological fungicide developed specifically for the control of pathogens such as Botrytiscinerea, Sclerotinia sclerotiorum and Monilinia spp. It is based on the naturally occurring non-pathogenic saprophytic fungus Ulocladium oudemansii Strain U3 and provides protection to blossoms, fruit and plant tissue.
BotryStop utilizes Ulocladium oudemansii Strain U3, a novel new biological weapon and approach to organically fight tough diseases. When BotryStop spores are deposited on the dead and senescent plant debris they germinate and colonize. The developing mycelia proceed to colonize dead tissue and additional sporulation can occur. These new spores are then available to colonize remaining plant debris. BotryStop aggressively occupies the same physical space and out-competes pathogens for the nutrients in dead and senescing plant tissue.

BotryStop General Treatment

General Application: Apply BotryStop at a range of 2-4 lbs. per acre. The most common rate is 3 lbs./acre.
Powdery Mildew: To cure powdery mildew, apply up to the maximum rate (5 lbs./acre) every week for three weeks.
. Do not exceed 2.0 tbsp. per gallon of water per week (equivalent to 5 lbs. per acre per week.)
. Shorten the interval during rainy weather or during periods of high relative humidity.
. Use sufficient water volume to provide complete coverage and wetting of plants.
. A non-ionic surfactant or spreader sticker must be used when making applications.
. Use of organosilicone surfactants is beneficial when spraying low water volumes (below 50 gallons per acre). Do not use organosilicone surfactants that claim to be “penetrants” or “stomatal flooders or infiltrators”.
. Ensure constant agitation throughout the loading, mixing and application operations.
. Multiple applications may be needed depending on crop and disease pressure.
