  As a commonly used fungicide of methoxyacrylic acid, pyraclostrobin has been widely concerned. This is because it has a wide range of bactericidal spectrum, many target pathogens, strong immunity, improving crop resistance, promoting crop growth, anti-aging and other characteristics. Basically, it is due to its excellent application performance.

Pyraclostrobin exerts its efficacy by inhibiting spore germination and mycelial growth, and has the functions of protection, treatment, eradication, penetration, strong systemicity and rain erosion resistance.

  Pyraclostrobin is mainly registered in more than 40 crops, including wheat, barley, soybeans, peanuts, grapes, vegetables,  potatoes, bananas, lemons, coffee, fruit trees, walnuts, tea trees, tobacco and ornamental plants.

It is used to prevent and cure diseases caused by nearly all types of fungal pathogens, such as ascomycetes, basidiomycetes, semi fungi and oomycetes. For example, powdery mildew, leaf blight, chocolate spot, web blotch and scab of wheat, rice blast, sheath blight, downy mildew and blight of rice have good activity, which is more important for the prevention and control of blight.

  Pyraclostrobin has a wide range of bactericidal spectrum and applications. It can prevent and cure plant diseases caused by almost all types of fungal pathogens, and promote plant growth. It can improve the activity of nitrate (nitrification) reductase, so as to improve the absorption of nitrogen in the rapid growth stage of crops. At the same time, it can reduce ethylene biosynthesis, thereby delaying crop senescence.

  Pyraclostrobin is highly selective, safe for crops, humans, livestock and beneficial organisms, and basically no pollution to the environment.

  Single dose mainly consists of 25% SC and 250g/L EC.

  Pyraclostrobin can be compounded with a variety of active ingredients, and also has synergistic effect.Common combinations include: pyraclostrobin + epoxiconazole, pyraclostrobin + difenoconazole, pyraclostrobin + tebuconazole, pyraclostrobin + metiram, pyraclostrobin + oxine-copper, pyraclostrobin +iprodione, etc.

  Pyraclostrobin is highly toxic to aquatic organisms; It has an impact on silkworm rearing and should be careful against drift; Risk of resistance due to abuse.


  1. The time of using pyraclostrobin bromide must be in advance, and it is necessary to prevent diseases as a protective agent, or it is better to use it at the early stage of diseases such as before sowing or after emergence.

  2. Although pyraclostrobin is good at prevention and persistence, compared with other targeted fungicides, the quick effect is still slightly insufficient. It is better to use it together with other fungicides.

  3. The action site of pyraclostrobin is relatively single, so the resistance is relatively fast. The number of uses must be controlled to avoid accelerating the generation of resistance.
