CK® Crop Keeper™ PhosGuard™

CK® Crop Keeper™ PhosGuard™ is a premium potassium phosphite (KH2PO3) fertilizer formulated to improve plant health, increase resistance against oomycete pathogens (such as downy mildew and Phytophthora), and enhance abiotic stress tolerance. Containing a high concentration of phosphorous acid (P₂O₅ equivalent) and potassium (K₂O equivalent), PhosGuard™ delivers rapid systemic protection and supports stronger root and shoot growth. Phosphite ions act as both a direct antimicrobial agent and a plant defense stimulator, activating natural resistance mechanisms. Potassium, an essential macronutrient, contributes to improved water regulation, enzyme activation, and carbohydrate metabolism, enhancing overall crop vigor.
