| Fungicide | Azoxystrobin is a methoxyacrylate fungicide. It is a broad-spectrum and high-efficiency fungicide with good systemic conductivity and strong permeability. It has the characteristics of long duration and long duration. It has protection, treatment and eradication effects on almost all fungal diseases. It can be used in various ways. It can not only be used for stem and leaf spray, it can also be used for seed treatment and soil treatment. There are more than 400 preparations registered in China's pesticide control office, which is also the most registered fungicide variety. azoxystrobin has good activity against almost all fungal diseases such as powdery mildew, rust, glume blight, net spot, downy mildew, rice blast, etc. It can be used for stem and leaf spray, seed treatment, and soil treatment. It is mainly used for grains, rice, peanuts, grapes, potatoes, fruit trees, vegetables, coffee, lawns, etc. The dosage is 25ml-50/mu. Azoxystrobin cannot be mixed with insecticide emulsifiable concentrate, especially organophosphorus emulsifiable concentrate, nor can it be mixed with silicone synergist. It will cause phytotoxicity due to excessive permeability and spreading. Acute oral:>5000mg/kg; Acute transdermal:>2000mg/kg. On protected tomatoes, the phytotoxicity of azoxystrobin has been found, and tomato seedlings must be used with caution within 2 weeks of transplanting. Studies have found that vegetable powdery mildew has developed resistance to azoxystrobin, and the effect has been significantly reduced after continuous application for more than 2 times. |
| main features | (1) broad sterilization spectrum: azoxystrobin is a broad-spectrum fungicide, which can be used to prevent and control almost all fungal diseases. spraying once can prevent and control dozens of diseases at the same time, greatly reducing the number of spraying times. (2) strong permeability: azoxystrobin has strong permeability. it does not need to add any osmotic agent during use, that is, it can penetrate across the layer. it can quickly penetrate to the back of the blade only by spraying the back of the blade, thus achieving the prevention and control effect of positive beating and negative death. (3) Good internal absorption conductivity: Azoxystrobin has strong internal absorption conductivity. Generally, it can be quickly absorbed by leaves, stems and roots and quickly conducted to various parts of the plant after application. Therefore, It can be used not only for spraying, but also for seed treatment and soil treatment. (4) long duration: azoxystrobin leaves are sprayed, the duration can reach 15-20 days, and the duration of seed dressing and soil treatment can reach more than 50 days, which can greatly reduce the number of spraying. (5) Good compounding: Azoxystrobin has a good compounding property, and can be mixed with dozens of drugs such as chlorothalonil, difenoconazole, dimethomorph, etc. The mixing not only delays the drug resistance of the germs, but also improves the control effect. |
| applicable crops | due to the wide range of azoxystrobin to control diseases, it can be applied to various food crops such as wheat, corn, rice, peanut, cotton, sesame, tobacco and other cash crops, tomato, watermelon, cucumber, eggplant, pepper and other vegetable crops, apple, pear, kiwi, mango, lychee, longan, banana and other fruit trees, Chinese medicinal materials, flowers and other hundreds of crops. |
| control object | azoxystrobin is a broad-spectrum fungicide, it can be used to prevent and control early blight, late blight, gray mold, leaf mold, base rot, downy mildew, blight, powdery mildew, anthracnose, gray frost disease, scab, black pox, spike brown blight, White rot, popping, leaf spot, wilt, brown spot, Verticillium wilt, leaf spot, frost blight and other fungal diseases, especially for powdery mildew, rust, glume blight, net spot, downy mildew, vine blight, late blight, rice blast and other diseases. It can achieve the goal of one spray and multiple treatments. |
| usage | (1) to prevent and control cucumber downy mildew, blight, anthracnose, scab and other diseases, the drug can be used at the initial stage of the disease. generally, 60-90 ml of 25% azoxystrobin suspending agent can be used per mu, and 30-50kg of water can be sprayed evenly, and the expansion of the above diseases can be better controlled in 1-2 days. (2) To prevent rice blast, sheath blight and other diseases, you can start medication before or at the beginning of the disease. Use 20-40 ml of 25% suspending agent per mu, spray once every 10 days, spray twice, you can quickly control the spread of the above diseases. (3) To prevent and control watermelon wilt, anthracnose, vine blight and other diseases, you can use the medicine before or at the beginning of the disease. Use 30-50 grams of 50% water dispersible granules per mu, every 10 days Spray once, spray 2-3 times, can effectively prevent the occurrence of the above diseases and further harm. |
| use | azoxystrobin is a new type of efficient, broad-spectrum and systemic fungicide. It can be used for stem and leaf spraying, seed treatment, and soil treatment. It is effective against almost all fungal diseases (Ascomycetes, Basidiomycetes, Oomycetes and Seminars), such as powdery mildew, rust, glume blight, retickle, downy mildew, rice blast, etc. It has good activity and has no cross resistance with existing fungicides. Used in cereals, rice, grapes, potatoes, vegetables, fruit trees and other crops, safe for these crops. |
