Description

Metalaxyl is a systemic fungicide belonging to the phenylamide class, renowned for its specific and potent activity against plant pathogens within the Oomycota phylum, such as those causing downy mildews and late blights. Its systemic nature allows for protective and curative action, making it a cornerstone in modern integrated disease management programs for high-value crops. This product is essential for agricultural producers, crop protection formulators, and research institutions focused on safeguarding yield and quality against devastating oomycete diseases.

Application

• Seed Treatment: Used as a dressing to protect seedlings from soil-borne oomycetes like Pythium and Phytophthora spp., ensuring healthy crop establishment.
• Foliar Spray for Vegetable Crops: Critical for controlling downy mildew in crops such as cucumbers, onions, grapes, and lettuce, as well as late blight in potatoes and tomatoes.
• Soil Drench/Application: Applied to the root zone to manage root and stem rots in ornamental plants, tobacco, and fruit trees caused by oomycete pathogens.
• Formulation Intermediate: Serves as a key technical-grade active ingredient for manufacturing various commercial fungicide formulations, including wettable powders, suspension concentrates, and seed treatment slurries.
• Turf and Ornamental Management: Employed in professional turf management and nurseries to control Pythium blight and other related diseases.
• Research & Development: Utilized as a reference standard and active compound in agricultural research for studying oomycete resistance, mode of action, and developing new synergistic mixtures.
