Plant Doctor LLC, Fungicide (Metalaxyl, 80 g/kg + Mancozeb, 640 g

Synergy of components for comprehensive protection

The product "kg+mancozeb, 640 g" by Zhenjiang Agrin Company Ltd. is a combined fungicide integrating both systemic and contact action. The core value of the formulation lies in the pairing of metalaxyl and mancozeb. Metalaxyl, a phenylamide derivative, penetrates plant tissues rapidly, providing protection for new growth and a curative effect, which is critical during early infection stages. Mancozeb establishes a protective barrier on the leaf surface, suppressing spore germination.

Mechanism of action and agronomic efficiency

This combination enables effective control over a wide spectrum of diseases: late blight, alternaria, downy mildew, and grape mildew. The systemic component blocks nucleic acid synthesis in fungal pathogens, while the contact component disrupts enzymatic processes, preventing the development of resistance in pathogens.
