In the list of global pesticide and fungicide single product rankings, pyraclostrobin has always been the best in the list. As a methoxyacrylic fungicide, it has been favored by users since its launch due to its broad-spectrum bactericidal, excellent effect, safety to crops, and growth-promoting effect on crops.
1. Which is better, pyraclostrobin EC, suspension concentrate or powder?
① DP
It will be scattered during processing and use, which will cause environmental pollution, which is the biggest problem of DP.
② EC
EC is the earliest widely used dosage form of pesticides, which is stable and has low manufacturing cost.
③ SE
SE is more advanced, and its process is stricter. Pyraclostrobin SE products have a great advantage in terms of safety. The suspension concentrate is very safe, but it is not recommended to use it in super concentration.
2. What is the relationship between pyraclostrobin, azoxystrobin, and Kresoxim-methyl?
They are called the three brothers of fungicides, and they all belong to methoxyacrylate fungicides. They are a new class of fungicides developed with natural methoxyacrylate antibiotics as lead compounds. And pyraclostrobin is considered to be the most active methoxyacrylate fungicide on the market.
3. Why are so many people using it?
① It has multiple effects on fruits and vegetables
It not only has protective and therapeutic effects, but also has good osmotic and systemic effects. It protects fruits and vegetables in an all-round way, so that germs have nowhere to escape. In addition, it can kill bacteria and promote crop growth. It can also be used in ways such as stem and leaf spray, water surface application, and seed treatment, without limitation.
② Wide application range and popular
Pyraclostrobin can be used in fruit trees, vegetables, strawberries, rice, tobacco, tea trees, ornamental plants, wheat, peanuts, lawns and other crops.
Prevention and control of powdery mildew, downy mildew, blight, anthracnose, scab, brown spot, leaf blight, rust, blight and other diseases caused by ascomycetes, basidiomycetes, deuteromycetes and oomycetes .
③ Less dosage, great effect (only for 25% pyraclostrobin suspension concentrate)
For most crops (such as trees, vegetables, etc.), it is recommended to dilute 1500~2000 times. Assuming that 30 catties of water is used alone, 10~15 grams of medicine is used; for compounding, 10 grams of water is used.
④ The compounding effect is good, the best partner
It can be compounded with a variety of medicaments, and also has synergistic effect.
For example, the effect of compound triazole fungicides is very good, which can improve the efficacy.
Mixed with foliar fertilizers such as potassium dihydrogen phosphate, adding trace elements, the effect will be very good.
Mixed with brassin to enhance disease resistance, reduce drug resistance, promote nutrient transformation, and regulate plant growth.
Both difenoconazole and pyraclostrobin are excellent fungicides. When they are compounded together, their advantages are complementary and synergistic, and they have a good control effect on hundreds of fungal diseases. For example, all kinds of fruits and vegetables, solanaceous fruits, fruit trees, powdery mildew, leaf spot, wilt, anthracnose, sheath blight, scab and rust on field crops. Protection plus treatment, good quick effect and long lasting effect.
