MilStop SP is a professional-grade foliar fungicide that rapidly suppresses and cures Powdery Mildew before it spreads. Formulated with potassium bicarbonate and built-in surfactants, MilStop SP destabilizes fungi at the cell level while altering leaf surface pH to prevent future spore germination. With no known resistance, it can be applied up to the day of harvest across commercial greenhouses, indoor grows, and field production.
