Decree 50 WDG is a Group 17 fungicide containing 50% Fenhexamid. It is a water-dispersible granule designed for the control of Botrytis diseases (such as Gray mold) in various greenhouse crops, ornamentals, forestry conifers, and non-bearing fruit trees and vines. It is also used to suppress Powdery Mildew in ornamentals. This product is for agricultural and ornamental horticultural use only and is not for residential use. When applying, ensure thorough coverage of flowers and fruiting parts for food crops. For ornamentals, coverage of foliage and stems is essential. Users should follow resistance management strategies, such as rotating with different Group 17 fungicides or using tank-mixes with different modes of action. Always use proper spray equipment calibration to minimize drift and ensure effective application. Note that this product is not registered for use on transplants or greenhouse production of cucumbers in California.
