Products Features
1. It has protective and eradication effects on diseases. When used before crops are infected, it can protect crops from pathogens; when used after crops are infected, it can prevent the spread and development of pathogens in the plant body, and has a significant inhibitory effect on the expansion of the initial disease spots of potato late blight and the production of zoospores.
2. It has a strong two-way internal absorption and conduction effect on crops, and the penetration and conduction in the plant body are very fast. The agent entering the plant body can be conducted in any direction, that is, it has apical and basal properties, and can also be conducted laterally. After the drug is absorbed by the roots and stems, it is transported to the leaves and young tissues that grow after the drug is applied along with the water circulation in the plant body, protecting the leaves and young tissues from being invaded by pathogens; after being absorbed by the upper leaves, it can be conducted to the base leaves and tissues to inhibit the reproduction and spread of pathogens in the group.
3. Long lasting effect. For seed treatment or root irrigation, the lasting effect is about 1 month; while foliar spray is about 15 days.
4. Strong selectivity, only effective against Oomycete diseases, including downy mildew, phytophthora, and pythium.
5. It is easy to cause drug resistance in pathogens, especially foliar spray. After two years of continuous use, drug resistance can be found in pathogens, making the drug suddenly ineffective. Therefore, a single agent of metalaxyl is generally only used for seed treatment and soil treatment, and is not suitable for foliar spray.
Products Applications
Metalaxyl is a highly efficient systemic fungicide that can be absorbed by roots, stems, and leaves and conducted upward. It is particularly effective against diseases caused by Algae Fungi and Moraxella. It can prevent and control downy mildew and blight of many crops such as melons, onions, spinach, tomatoes, tobacco, grapes, Chinese cabbage, cabbage, kale, and cauliflower.
Metalaxyl is a new type of highly effective systemic fungicide. It can be absorbed into the plant and is much more water-soluble than general fungicides. It has selective effects on downy mildew and phytophthora in the Oomycetes, for example, it has good control effects on potato late blight, grape downy mildew, hop downy mildew, beet blight, rape white rust, tobacco black shank, etc. It can also be used for cotton damping-off and millet white disease, with good control effects.
