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.
Dimethomorph is a new type of systemic low-toxicity agent. It disrupts the formation of bacterial cell membranes. This leads to the breakdown of spore sacs and kills pathogens. It has strong systemic properties. Applying it to the roots allows it to enter all parts of the plant. Spraying it on leaves enables penetration into leaf tissues. It does not have cross-resistance with other agents like metalaxyl.
Dimethomorph acts on pathogens in three main ways:1. Preventive action: It stops spore germination and invasion. 2. Therapeutic action: It penetrates plant tissues and kills fungal mycelium. 3. Anti-spore action: It prevents spore formation and reduces infection sources. This unique mechanism and multi-stage action provide excellent control of downy mildew and late blight.
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.
Features of Dimethomorph
1. Wide range of applicable crops and broad spectrum of activity.
Dimethomorph effectively controls downy mildew, potato late blight, and other low fungi diseases.
It can be applied to grapes, lychees, cucumbers, melons, bitter melons, tomatoes, peppers, potatoes, and cruciferous vegetables.
2. Good efficacy and long-lasting effect.
Dimethomorph has a unique mechanism of action.
It effectively targets all developmental stages of oomycetes, showing exceptional efficacy against various downy mildew and late blight.
It offers both preventive and therapeutic effects, along with anti-spore action.
The application interval for acetamiprid is usually around 7 to 10 days, which is 3 to 4 days longer than other agents, reducing application frequency and saving time and costs.
3. Strong systemic properties.
It has strong systemic properties.
When applied to the roots, it quickly penetrates all parts of the plant.
Spraying on leaves allows it to rapidly enter leaf tissues for comprehensive fungicidal effects.
4. No development of resistance.
Dimethomorph has no cross-resistance with other fungicides like metalaxyl and cymoxanil.
It can quickly kill pathogens resistant to other fungicides, ensuring stable efficacy.
5. Resistant to rainwash.
Its high solubility and dispersibility allow rapid penetration into leaves and localized diffusion.
It resists wash-off from rain, maintaining efficacy even after rain within one hour of application.
It enhances photosynthesis, resulting in brighter colors in fruits and vegetables, and improves overall crop yield and quality.
6. Good compatibility.
Using acetamiprid alone has a high risk of resistance development.
For example, users may report ineffective control of vegetable downy mildew due to resistance.
It is recommended to mix Dimethomorph with fungicides of different mechanisms, such as mancozeb, chlorothalonil, and organic copper preparations like oxine-copper.
This can delay the development of resistance.
Dimethomorph can also be mixed with azoxystrobin, pyraclostrobin, cymoxanil, mancozeb, propineb, Ametoctradin, thiram, chlorothalonil, phosethyl-al pyridaben, amino-oligosaccharin, prochloraz, metalaxyl, zhongshengmycin, iprodione and others.
(7) Low toxicity and good safety.
Dimethomorph remains safe even during flowering and fruit swelling stages.
It is a low-toxicity fungicide, making its use safer for growers.
It has low toxicity to bees and birds and shows no harmful effects on silkworms.
Its low-toxicity characteristics do not affect the fungicidal speed against plant diseases.
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.
Application of Dimethomorph
Dimethomorph effectively controls downy mildew, potato late blight, and other low fungi diseases. It can prevent and control downy mildew in cucumbers, downy mildew in melons, blight in taro, blight in peppers, and downy mildew in cruciferous vegetables.
Dimethomorph is primarily used to control diseases through spraying; for disease affecting the collar or neck of roots, it can also be applied to the collar and surrounding soil.
When controlling diseases in grapes, lychees, or root and stem diseases, the recommended dilution is as follows: use 50% water-dispersible granules at a ratio of 1500 to 2000 times, 80% water-dispersible granules at 2000 to 3000 times, 40% water-dispersible granules at 1000 to 1500 times, 25% wettable powder at 800 to 1000 times, or 10% emulsifiable concentrate at 300 to 400 times, applied via spraying or drenching.
For controlling diseases in melons, solanaceous crops, leafy vegetables, and tobacco, generally use 35 to 50 grams of active ingredient per 667 square meters, mixed with 30 to 60 liters of water for spraying. The application is most effective before disease occurrence or at the initial signs of disease.
