Decree 50 WDG Fungicide
Decree Fungicide is the new standard for Botrytis. 12-hour REI allows for Botrytis control in propagation and at retail, while 7-14 Day Residual Control gives growers the best value per application. "Reduced-Risk" classification means Decree is safe and easy for all employees to apply. Decree can be applied to flowers in bloom and poinsettias in full color with little detectible residue and no phytotoxicity. Being in a unique new chemistry class makes Decree an excellent fungicide rotational partner.
Active ingredient: 50% Fenhexamid
Mode of action: Decree is characterized by protective and curative action with residual activity against Botrytis cinerea in ornamentals. Decree seems to be a single-site inhibitor with a very specific biochemical mode of action.
At very low concentrations, it inhibits hyphal growth and germ tube elongation of Botrytis cinerea. The germ tube growth stage is considered to be the most sensitive stage in the life cycle of Botrytis cinerea (happening outside the plant tissue, on the plant surface, before penetration of the leaf cuticle).
Rate of application:
For high volume spray equipment: The labeled application rate for Decree is 0.75 to 1.5 pounds of product per 100 gallons of spray to be applied before disease establishment or at the first sign of disease. Apply sufficient amount of spray solution to obtain complete coverage of flowers, foliage and stems.
- For small equipment applications: Use 0.16 ounces or 4.5 grams or approximately 1 rounded teaspoon per 1 gallon of water before disease establishment or at the first sign of disease.
For agricultural and ornamental horticultural use only. Not for residential use.
