Thiophanate-methyl is a substituted benzimidazole fungicide. It is highly effective and low in toxicity. This fungicide has excellent systemic properties and controls a broad spectrum of fungal diseases. It effectively combats leaf spot, sooty mold, rust, anthracnose, ring spot, and gray mold. Users can apply it through foliar spraying, seed treatment, and soil application.
Thiophanate-methyl serves as both a preventive and therapeutic fungicide. It primarily acts through systemic absorption but also exhibits some contact activity. After application, part of it converts to carbendazim on the plant surface, which provides good protection. Another part gets absorbed into the plant and converts to carbendazim as well. This conversion interferes with the formation of fungal mycelium, inhibits spore germination, and obstructs cell division, achieving effective fungicidal effects.
Mancozeb, belonging to the dithiocarbamate class of sulfur-based agents, transforms into EBIS and EBI when sprayed on the surface of plants under the influence of water and air. This process creates a dense protective film on the surfaces of leaves and fruits that is breathable, water-permeable, and light-permeable. This film inhibits the germination and invasion of pathogen spores and disrupts the activity of various enzymes necessary for the normal physiological metabolism of pathogens, thereby achieving the goal of sterilization and disease prevention by suppressing the germination of pathogen spores and exerting fungicidal effects.
Features of Mancozeb
1. Wide Sterilization Range: Mancozeb can prevent (and control) various crops' downy mildew, late blight, anthracnose, leaf spot, leaf drop, leaf blight, ring spot, white rot, scab, black core disease, powdery mildew, black leg disease, and more.
2. Stable and Excellent Fungicidal Performance: There is no significant resistance of pathogens to mancozeb, allowing it to be applied multiple times on the same crops or in the same field without the need to switch to different fungicides. Additionally, its residue is relatively low (generally tending towards zero two months after application), making it safe for crops.
3. Good Compatibility: Mancozeb can be mixed and used with various fungicides and insecticides (such as difenoconazole, fluorosilicone, prochloraz, carbendazim, thiophanate-methyl, metalaxyl, Bordeaux mixture, chlorothalonil, and dimethomorph), as well as foliar fertilizers. Especially when mixed with systemic fungicides, it can not only enhance efficacy and prolong the duration of effectiveness but also delay the development of resistance to systemic agents while expanding its sterilization range.
4. More Stable Molecular Structure Compared to Other Similar Fungicides: When sprayed on crops, mancozeb's conversion is more stable and controllable, which in turn promotes better efficacy against diseases and higher safety for crops.
5. Good Nutritional Components: In addition to its strong fungicidal ability, when applied during crop growth, the zinc and manganese contained in the formulation can also be absorbed by crops to promote their growth and development (zinc is beneficial for the growth of young buds and tender leaves, while manganese is an essential element for photosynthesis in leaves), enhancing the crops' resistance to stress.
6. Low Usage Cost: Compared to other fungicides, its cost per acre is lower.
Application of thiophanate-methyl
Thiophanate-methyl is highly effective in controlling various fungal diseases, including but not limited to the following kinds:
1. Downy Mildew: This is a common plant disease that primarily affects leaves, causing yellow and white spots, and can lead to leaf death in severe cases. Thiophanate-methyl can effectively inhibit the growth of downy mildew fungi, thereby controlling the development of the disease.
2. Anthracnose: Anthracnose is a fungal disease that affects a variety of crops, primarily manifesting as brown lesions on leaves and fruits, which can lead to plant death in severe cases. Thiophanate-methyl has a significant inhibitory effect on anthracnose fungi and can be used to control anthracnose in various crops.
3. Wilting Disease: Wilting disease is a soil-borne disease that primarily affects the roots and stems of crops, leading to plant wilting and death. Thiophanate-methyl can effectively control the occurrence and spread of wilting disease through soil treatment or irrigation application.
4. Powdery Mildew: Powdery mildew is a common leaf disease that primarily affects leaves and stems, causing a white powdery substance to cover the leaf surface. Thiophanate-methyl has a significant preventive effect against powdery mildew fungi and can be used to control powdery mildew in various crops.
5. Rust Disease: Rust disease is a typical fungal disease that primarily affects the leaves and stems of crops, causing rusty lesions on the leaves. Thiophanate-methyl has an inhibitory effect on rust fungi and can be used to control rust disease in various crops.
Application of Mancozeb
For crops such as corn, wheat, peanuts, sorghum, rice, and tomatoes, seed coating, soaking, and mixing methods can prevent seed-borne diseases and soil-borne diseases at the seedling stage. For field crops and vegetables, the application rates are generally 40 to 50 liters of solution per acre for manual spraying, 7 to 10 liters per acre for tractor spraying, 1 to 2 liters per acre for aerial spraying, and 200 to 300 liters per acre for manual spraying on fruit trees. In addition to disease prevention, it also stimulates plant growth, typically using a dilution of 600 to 800 times the 75% mancozeb wettable powder.
