Metalaxyl M is a fungicide and soil disinfectant that has a dual role in protecting and treating crops. It has been widely used.
Characteristics of Metalaxyl M
1. Strong systemicity
When the agent is sprayed on crops, it can be absorbed by the seeds, roots, stems, and leaves of the crops and transmitted to various parts, which can protect and treat the crops well.
2. High safety
Metalaxyl M is an upgraded version of Metalaxyl. Under the same conditions, only half of the amount of Metalaxyl is needed, which increases the safety of the environment and users.
It is absorbed into the body of crops in a short time, is resistant to rain erosion, and basically does not cause drug damage.
3. Multiple application crops
Metalaxyl M has a good control effect on diseases caused by downy mildew, phytophthora, and pythium, and can be applied to many crops.
For example: prevention and control of downy mildew and blight of melons; late blight of tomatoes and potatoes; black leg of potatoes; downy mildew of cabbage; blight of leeks; downy mildew of onions and spinach; blight of peppers; cottony mildew of tomatoes; downy mildew of grapes; damping-off of citrus seedlings, etc.
Precautions for metalaxyl-M
1. In addition to soil treatment, this agent is generally used in compound preparations. Using it alone is likely to induce pathogen resistance.
2. The spray can be mixed with protective fungicides such as mancozeb to improve efficacy and reduce resistance.
3. It cannot be mixed with alkaline agents to avoid decomposition and ineffectiveness.
Agents with similar effects to metalaxyl-M
1. Oxymexazole
Oxymexazole has a good effect on Pythium and some soil-borne diseases (damping-off disease, damping-off disease), but the dosage should be controlled when using it to prevent inhibiting crop growth.
2. Fludioxonil
Fludioxonil also has a good effect on soil-borne diseases such as sheath blight, damping-off, stem base rot, and vine blight.
Although the above agents have many similarities with metalaxyl, they are not as easily absorbed as metalaxyl, so they can generally be used in combination.
Mixing of metalaxyl
Metalaxyl alone is likely to induce pathogen resistance, so it is generally mixed to better exert the efficacy of metalaxyl.
Let's talk about the combination of metalaxyl:
1. Azoxystrobin
Applicable crops: cucumber, tomato, pepper, watermelon, cabbage, corn, wheat, peanut, potato, green onion, cotton, garlic, etc.
Targeted diseases: root rot, stem base rot, anthracnose, downy mildew, damping-off, damping-off, sheath blight, vine blight and other diseases.
Note: Do not use on windy and rainy days to prevent drug damage.
2. Metalaxyl-Methyl Mancozeb
For diseases: downy mildew, blight, white rust, damping-off, fruit rot of various crops. The most commonly used ones are late blight of tomatoes and potatoes, downy mildew of various melon crops, and downy mildew of grapes.
Notes:
(1) Try to use it in the early stage of the disease to achieve better results.
(2) It is recommended to use it alternately with other fungicides (such as oxadone, oxadone, cymoxanil, etc.) to avoid drug resistance.
(3) When used in combination with other agents, it is recommended to test it first to avoid drug damage.
3. Metalaxyl-Methyl Mancozeb
Applicable crops: rice, melons and fruits, vegetables, fruit trees, flowers, lawns and seedlings.
For diseases: damping-off, wilt, fusarium wilt, verticillium wilt, damping-off, sclerotinia, root rot, root rot and stem base rot, etc.
Note: It is mainly used for the roots of crops in the seedling stage; if it rains after spraying, no additional spraying is required.
4. Metalaxyl
Applicable crops: cucumber, pepper, melon, zucchini, tomato, eggplant, cruciferous vegetables, potato and grapes, etc.
Targeting diseases: It is mainly used to prevent and control low-level fungal diseases, such as downy mildew, phytophthora, pythium, blight, blight rot, late blight, damping-off, etc., and also prevent some high-level fungal diseases, such as anthracnose, brown spot, early blight, leaf spot, damping-off, etc.
Note: It may cause drug damage on red grapes and should be used with caution; according to the location of the disease, choose the appropriate method of medication (such as root irrigation for root problems and spray for leaf problems).
In addition to the above combinations, metalaxyl can also be combined with cymoxanil, ethylene phosphatide aluminum and other agents, which also have good effects in preventing and controlling some diseases.
