Pyraclostrobin fungicide is a mitochondrial respiration inhibitor. It blocks electron transfer between cytochrome b and C1. This inhibition prevents ATP production. Consequently, it leads to cell death. Pyraclostrobin strongly suppresses spore germination in pathogens. It shows significant antibacterial activity against various fungal pathogens. It has protective and curative effects. Pyraclostrobin fungicide penetrates well and can be applied via foliar sprays, surface treatments, or seed treatments. It is highly selective and safe for crops, humans, livestock, and beneficial organisms. It causes minimal environmental pollution. Additionally, it enhances physiological functions in crops and boosts their resilience.
Propineb, belonging to the class of dithiocarbamate fungicides, offers protective effects with a long residual period, rapid efficacy, and a broad spectrum of activity. Its mechanism of action primarily targets the fungal cell wall and protein synthesis, inhibiting the oxidation of pyruvate within the pathogens. This effectively prevents the infection and germination of the pathogens as well as the growth of mycelium. Additionally, due to its zinc content, Propineb promotes plant growth and enhances fruit quality.
Features of Pyraclostrobin
1. Broad Spectrum of Activity and Wide Application Range
Pyraclostrobin fungicide exhibits excellent activity against nearly all types of fungal diseases. It can be used to control leaf spot diseases, rust, powdery mildew, downy mildew, blight, anthracnose, scab, brown spot, damping-off, and other plant diseases caused by various fungal pathogens. It is widely applicable to over 100 crops, including wheat, peanuts, rice, vegetables, fruit trees, tobacco, tea plants, and ornamental plants.
2. Combination of Prevention and Treatment with Health Benefits
Pyraclostrobin fungicide has both protective and curative effects, with good penetration and systemic action. It can be applied through foliar sprays, surface treatments, and seed treatments.
Additionally, Pyraclostrobin fungicide can induce physiological changes in many crops (especially cereals), enhancing nitrogen absorption during rapid growth stages, reducing ethylene biosynthesis, and delaying crop senescence. When crops are attacked by pathogens, it accelerates the formation of resistance proteins, improving the crops' innate immunity and enhancing their resilience to adverse growth factors.
3. Good Compatibility, Safe and Low Toxicity
Pyraclostrobin fungicide can be mixed with various fungicides, such as benzimidazole, mancozeb, acibenzolar-S-methyl, and triazoles. This not only broadens its spectrum of activity but also allows for synergistic effects. It can also be mixed with various insecticides, plant growth regulators, and foliar fertilizers, achieving multiple functions in a single application, including disease prevention and treatment, pest control, growth regulation, and nutritional supplementation. This versatility is a key reason why Pyraclostrobin fungicide frequently appears in various yield-increasing formulations.
Moreover, Pyraclostrobin fungicide is characterized by its resistance to rain wash-off, long-lasting efficacy, low toxicity, and safety for users and the environment.
Features of Propineb
2. Broad Spectrum
Propineb demonstrates excellent control over a variety of diseases, including but not limited to downy mildew on vegetables, anthracnose, and brown spot. It inhibits the synthesis of fungal cell walls and proteins, preventing spore infection and germination while also suppressing mycelial growth, leading to deformation and death of the pathogens.
3. Good Safety Profile
Propineb is safe for many crops, with a low risk of phytotoxicity. It has low toxicity, no unpleasant odor, and is safe for users and bees. It can be applied during flowering without affecting normal crop growth and pollination.
4. Promotes Crop Growth and Enhances Fruit Quality
Containing zinc, which is easily absorbed by crops, Propineb promotes plant growth and improves fruit quality. It enhances crops' resistance to drought, disease, and cold, while also boosting their ability to resist viruses.
5. Versatile Application Methods
Propineb can be used to control a range of crop diseases, such as downy mildew on cucumbers, downy mildew on Chinese cabbage, early blight and late blight on tomatoes, as well as anthracnose on mangoes. Application methods include spraying and others.
Application of Pyraclostrobin
Pyraclostrobin fungicide can be used on various crops, including wheat, peanuts, rice, vegetables, fruit trees, tobacco, tea plants, ornamental plants, and lawns. When pathogens come into contact with the fungicide, it inhibits their mitochondrial respiration and spore germination, ultimately leading to cell death and significantly reducing the spread of the disease.
Pyraclostrobin effectively controls multiple diseases such as powdery mildew, fusarium head blight, downy mildew, brown blight, leaf spot, scab, black rot, anthracnose, wilt, and root rot. At the early stages of disease onset, we can apply a 2000-fold dilution of 25% pyrazole fungicide via foliar spray, repeating every 7 days for 2 to 3 applications based on disease severity.
Prevention should be the primary focus; spraying before or at the early stages of disease can help minimize losses. If crops are already in the late stages of disease, we can mix it with other fungicides to enhance the control effect.
Application of Propineb
Propineb is a protective fungicide that must be applied before or at the onset of disease. It should not be mixed with copper-based products or alkaline agents. If copper products or alkaline agents are sprayed, wait one week before using propineb.
Application Method
Apply the fungicide before disease onset or at the initial stage of infection. Depending on the severity of the disease in the crops, it is typically applied 3-4 times, with intervals of 5-7 days between applications.
1. Grapevine Downy Mildew
Spray 70% wettable powder diluted at 400-700 times when the disease first appears. Approximately three applications should be made, with intervals of about 7 days.
2. Citrus Anthracnose
At the initial stage of the disease, use 70% wettable powder diluted at 600-800 times for spraying.
3. Tomatoes
- Early Blight: Early blight typically occurs when tomatoes are just starting to bear fruit. Use 125-190 grams of 70% wettable powder per acre, diluted with water for spraying. Apply approximately every 5-7 days for 2-3 consecutive applications to see results.
- Late Blight: After late blight appears, remove infected plants before spraying. Use 150-220 grams of 70% wettable powder, applying approximately 2-3 times with intervals of 5-7 days.
4. Cucumber Downy Mildew
After planting outdoor cucumbers, they are prone to disease in humid and warm conditions. Remove infected leaves before spraying. Use 150-215 grams of 70% wettable powder diluted with water for spraying. A total of 3 applications should be made, with intervals of 5-7 days. To enhance preventive effects, spray once after rain.
5. Apple Scab and Leaf Drop Disease
This disease easily infects tender leaves. When the disease occurs, spray with 70% wettable powder diluted at 600-700 times. Apply 3-4 times, with intervals of 7 days, and make an additional application in the autumn.
6. Tobacco Red Spot Disease
At the initial stage of the disease, use a 500-700 times diluted solution or 90-130 grams of 70% wettable powder. Apply approximately 3 times, with longer intervals of about 10 days.
7. Mango Anthracnose
Start spraying with 70% wettable powder diluted at 500 times during the flowering period of mangoes, especially when there is a lot of rain. A total of 4 applications should be made, with intervals of 10 days between each application.
