Metalaxyl

Metalaxyl is a systemic fungicide belonging to the phenylamide group, widely used to control diseases caused by oomycetes, including downy mildew, late blight, and damping‑off. It works by inhibiting RNA synthesis in fungal pathogens, providing both preventive and curative activity. Metalaxyl is rapidly absorbed by plant roots and foliage, with translocation throughout the plant to protect new growth. Formulations include emulsifiable concentrates, wettable powders, granular products, and seed treatments, allowing flexible application as foliar sprays, soil drench, in‑furrow treatment, or seed coating. It is commonly used in crops such as potatoes, tomatoes, grapes, vegetables, citrus, ornamentals, and turf. Due to its specific mode of action, metalaxyl is often formulated or tank‑mixed with other fungicides to manage resistance and broaden disease control. Users should follow label instructions carefully regarding application rates, pre‑harvest intervals, and rotational practices. For growers seeking reliable control of oomycete diseases, metalaxyl delivers effective systemic protection.
