As one of the important methoxy acrylate fungicides, pyraclostrobin has a broad bactericidal spectrum, many target pathogens, strong immunity, enhances crop resistance,promotes crop growth, anti-aging, etc. The functions of this type of fungicides can be verified and approved by most users.
1. Pyraclostrobin, emulsifiable concentrate, suspension concentrate, powder which is better? Generally speaking, each has its own differences. 1） The powder will drift during processing and use, which will cause environmental pollution, which is the biggest problem of powder. 2）Emulsifiable concentrates were originally used toluene and xylene, but the country now does not advocate registration of emulsifiable concentrates. Instead, microemulsions , water emulsions, or vegetable oils are used instead. This is a relatively backward formulation, but some products must be made. Into an emulsifiable concentrate. 3）Suspending agent suspending agent is more advanced, the suspending agent technology is stricter, and the processing cost is also high, but the state is not stable, and dela mination may occur after long-term storage. 2. What disease does pyraclostrobin cure? Pyraclostrobin can be used in various crops such as wheat, peanuts, rice, vegetables, fruit trees, tobacco, tea trees, ornamental plants, lawns and so on. Prevention and treatment of various diseases such as leaf blight, rust, powdery mildew, downy mildew, blight, anthracnose, scab, brown spot, and blight caused by ascomycetes, basidiomycetes, imperfect fungi and oomycete fungi. Good for cucumber powdery mildew, downy mildew, banana scab, leaf spot, grape downy mildew, anthracnose, powdery mildew, early blight, late blight, powdery mildew and leaf blight of tomatoes and potatoes Control effect. 3.How much water do you add? (1) How many catties of water is used for 100g? You can hit 300 kilograms of water. (2) Can a bucket of water use 20 grams? If it is used on crops such as wheat and rice, there is no problem, but when it is used on sensitive crops, such as strawberries, it may cause phytotoxicity. Therefore, 10 to 15 g of a bucket of water is a relatively safe amount. 4.cereal crops Pyraclostrobin has broad-spectrum bactericidal activity against cereal crop diseases. (1) It has an outstanding control effect on the diseases of cereal leaves and ears and grains, and the effect of increasing yield is remarkable. Using its single agent as a treatment test can effectively control wheat leaf blight, and at the same time, it can also observe the concurrent treatment of wheat glume blight. Even when the disease is severe, pyraclostrobin can effectively prevent leaf rust and stripe rust from harming barley and wheat. It can also cure barley leaf blight and reticulation. Pyraclostrobin is also effective Land control of other cereal diseases: such as wheat spot blight, snow rot and white spot, and barley moir. (2) Is it a small amount of 10g per mu to make a set meal on wheat? If it is a compound, it is not small, but it is a bit small if it is used alone. If you use it for the first time, you can use 10-20 grams of an acre of land. If you use it for the second time, it is recommended to mix something. 5.legume crops (1) Pyraclostrobin has a good control effect on the main diseases of beans such as bean leaf spot, rust and anthracnose. (2) Pyraclostrobin can effectively control peanut brown spot, black spot, snake eye, rust and scab. In addition, it also has a good control effect on peanut white sclerosis.
Fruit and vegetable crops
6.Usage and dosage on grapes (1) How to use it? For example, to prevent and treat downy mildew, powdery mildew, gray mold, brown spot, cob brown blight, etc. Pyraclostrobin can be added, and it can be used alone when the grapes are on the first leaves. Prevent and The leaves will also turn green. (Pyraclostrobin has a significant effect on grape powdery mildew and frosty fruit, even wh en the disease is more serious.) (2) How much is the amount on the grapes? If you use 30 kilograms of water on the grapes alone, use 10 grams to 15 grams; if you want to mix, use 10 grams of water per pot; if yo u mix 100 grams of pyrazole, use 300 kilograms of water with water. Diseases, such as grape downy mildew, can be used with propamocarb or dimethomorph. Pyraclostrobin has a good control effect on the main diseases of tomato and potato such as early blight, late blight, powdery mildew and leaf blight.
7.How to use citrus?
It is used before the high incidence of diseases, such as common anthracnose, sharp skin, and scabs, which have a good preventive effect.
The research results show that pyraclostrobin has a good control effect on citrus scab, resin disease and black rot. If used interchangeably with other agents, it can also improve the
quality of citrus.
8.How to use Pyraclostrobin Suspension Concentrate on pear trees?
Use 20~30g per mu of land and mix with 60 kg of water to spray evenly to prevent pear scab. Difenoconazole and other fungicides can also be compounded.
9.How to use Apple? Mainly prevent fungal diseases, such as powdery mildew, early leaf fall disease, leaf spot disease, etc. But it should be noted that it is sensitive to some varieties of Gala. 10.How much is the amount of mango in Hainan? Basically 10g/pot, if you use a pot of 30 kg of water, 10g is enough, if you use it alone, you can use 10-15g of water per pot. 11.How to use red dates? Red dates can be used to prevent coal pollution during flowering and late anthracnose. The first pass is 2000 times singles, and the second pass is compounded with tebuconazole or difenoconazole (coal pollution plus aphids).
