Key Benefits: Metalaxyl (8%): A systemic fungicide that is absorbed quickly by plant roots and foliage. It moves upward within the plant's vascular system to halt fungal growth from the inside and cure established infections. Mancozeb (64%): A contact fungicide that stays on the surface of the plant. It creates a protective shield that inhibits spore germination and disrupts multiple biochemical processes in fungal cells on the exterior.
