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.
Myclobutanil fungicide is a triazole-type systemic fungicide with low toxicity that serves both preventive and therapeutic purposes. Its mechanism of action involves inhibiting the biosynthesis of ergosterol in pathogens, leading to abnormalities in the pathogen's cell membrane and ultimately resulting in pathogen death. Myclobutanil has strong systemic properties, high efficacy, a long duration of action, is safe for crops, and has a certain growth-promoting effect.
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.
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.
Application of Myclobutanil
1. Fruit Tree Diseases
(1) For the control of sigatoka, spray a 5% emulsion or a 5% high-concentration emulsion diluted 1000 to 1500 times.
(2) For the control of powdery mildew on apples and grapes, spray once every two weeks with a 25% emulsion diluted 3000 to 5000 times, showing significant therapeutic effects.
(3) For the control of pears and apples scab
spray a 5% emulsion or a 25% emulsion diluted 4000 to 5000 times, or a 40% wettable powder diluted 8000 to 10000 times, or a 5% high-concentration emulsion diluted 1500 to 2000 times. Combining with mancozeb will improve disease prevention efficacy.
2. Control of Various Diseases Affecting Cereals
(1) For the control of loose smut and stinking smut, use 40 to 60 ml of a 25% emulsion per 100 kg of seeds; for wheat head blight, use 60 to 80 ml of a 25% emulsion per 100 kg of seeds, mixed with a small amount of water for seed treatment.
(2) For the control of wheat powdery mildew, apply 2 to 4 grams of active ingredient per acre, equivalent to 40 to 80 ml of a 5% emulsion, or 34 to 67 ml of a 6% emulsion, or 17 to 33 ml of a 12% emulsion, or 16 to 32 ml of a 12.5% emulsion, or 8 to 16 ml of a 25% emulsion, with regular spraying in water.
3. Control of Cucumber Powdery Mildew
Apply 30 to 40 ml of a 5% emulsion or a 5% high-concentration emulsion per acre, with regular spraying in water.
4. Control of Water Bamboo Leaf Spot Disease and Rust
Spray once at the initial onset and once during peak occurrence with a 12.5% emulsion diluted 1000 to 2000 times, achieving significant results.
