METALAXYL-MANCOZEB

Description

Introduction and Mode of Action: Metalaxyl-Mancozeb is a protective and curative fungicide containing two active ingredients:

• Metalaxyl (from the Acylalanine group) inhibits protein synthesis in fungal structures, leading to disease control.
• Mancozeb (from the Ethylenebisdithiocarbamate group) interferes with fungal respiratory enzymes, effectively stopping fungal growth.

This fungicide is effective against Pythium and Phytophthora fungi in soil and controls downy mildew in potatoes and cucumbers.

Application and Dosage

Pre-Harvest Interval (PHI)

• The interval between the last spraying and harvest is 7 days for potatoes and cucumbers.

Application Management

• Metalaxyl is absorbed through the roots, stems, and leaves, while Mancozeb provides a protective coating, preventing fungal infection.
• For downy mildew, the fungicide should completely cover the plant’s aerial parts.

Method of Use

1. Select and calibrate a suitable sprayer.
2. Dissolve the recommended amount of fungicide in a small quantity of water.
3. Pour this solution into a half-filled calibrated sprayer tank.
4. While stirring, add the remaining required water.
5. Ensure continuous agitation of the sprayer tank during both preparation and spraying.

Precautions

• Avoid ingestion, contamination of food or animal feed, and direct contact with skin, eyes, and clothing.

• Storage temperature should be between 10°C and 35°C.
• Once opened, the pesticide’s shelf life may decrease.
