GENERAL
PRESTOP contains a naturally occurring soil fungus. The effect of PRESTOP comes from several factors. The microbe deprives pathogen fungi of living space and nourishment by colonizing plant roots in advance of pathogens. In addition, the microbe acts as a hyperparasite for harmful fungi by producing enzymes, which results in lysis of cell walls of pathogens.
PRESTOP suppresses the listed fungal diseases on the specified greenhouse grown vegetables, herbs, ornamentals and cannabis (marihuana) that is produced commercially indoors. PRESTOP is not recommended for treatment of unrooted cuttings.
RESTOP is compatible with IPM programs.

DIRECTIONS FOR USE
PRESTOP is a wettable powder, packed in air-tight, moisture-proof packets. PRESTOP should always be prepared as an aqueous suspension, and then applied in one of three ways: as a growing media treatment, as a drench treatment or as a foliar spray treatment. PRESTOP is most effective when applied preventatively, before disease starts. Refer to the Crops Treated and Diseases
Suppressed section for information on what diseases PRESTOP will suppress on specific crops.
Refer to PRESTOP Mixing Instructions section for directions as how to prepare an aqueous suspension of PRESTOP. Refer to the Application Timing, Methods and Rates section for specific information on when to apply PRESTOP, application instructions, and use rates

APPLICATION TIMING, METHODS and RATES
Application Timing
The effect of PRESTOP is preventative. Start by treating the growing media prior to seeding, transplanting or potting, or else make a drench application immediately after seeding, transplanting or potting. Once seeds are sown or seedlings transplanted, additional applications of PRESTOP can be made as a drench or foliar application. Always use an aqueous suspension of the product. Repeat applications every 3 to 6 weeks, with the shorter interval used under conditions of moderate to high disease pressures. For suppression of foliar diseases, re-apply every 3 to 4 weeks as a foliar spray application.
