Pyraclostrobin has been on the market for a long time, and everyone knows a lot about its use. Farmers mainly use it to prevent and control powdery mildew, leaf blight, red spot, web spot, black smell, rice blast, sheath blight, downy mildew, blight, etc. It can be said that it performs quite well in terms of sterilization. We often use its compound products when we use it, let's learn about it together!
What are its commonly used compound products?
1. Pyraclostrobin and metiram compound agent pyraclostrobin·metiram: mainly used to prevent and control grape downy mildew, cucumber downy mildew, apple spot leaf fall, anthracnose, ring rot, citrus scab, potato late blight, etc.
2. The compound of pyraclostrobin and difenoconazole, benzoyl·pyraclostrobin, is used to control banana leaf spot, grape powdery mildew, watermelon powdery mildew, cucumber vine blight, apple tree spot leaf fall, etc.
3. The compound of pyraclostrobin and prochloraz is used for citrus and apple anthracnose.
4. The compound of pyraclostrobin and mancozeb, pyraclostrobin·mancozeb water dispersible agent, is used for citrus scab, and the wettable powder is used for spot leaf fall.
5. The compound of pyraclostrobin and tebuconazole, pyraclostrobin·tebuconazole, is used to control apple spot leaf fall, brown spot, banana leaf spot, wheat powdery mildew, fusarium head blight, and corn leaf spot.
6. The compound of pyraclostrobin without oxazolidinone is used for cucumber, grape downy mildew, potato late blight, and early blight.
7. There are many compound combinations that are not explained here. They have been mentioned in previous articles, for example, pyraclostrobin + potassium dihydrogen phosphate + brassinolide; pyraclostrobin + potassium dihydrogen phosphate + naphthylamine; pyraclostrobin + triadimefon, etc., which can improve quality and increase production and kill bacteria and eliminate drug damage.

How to mix correctly? What matters need to be paid attention to?
1. Farmers also know that pyraclostrobin is weakly acidic in the past use process, so when mixing, special attention should be paid to not mixing with alkaline fungicides, emulsifiable concentrates, and silicones. In order to avoid reducing the efficacy or causing drug damage, if you can't make an accurate judgment, you can add a little first, observe the phenomenon of stratification, precipitation, uneven color, bubbles, etc., and don't mix them.
2. Pay attention to the order of adding when mixing. If there is foliar fertilizer, the foliar fertilizer must be dissolved first, and the emulsifiable concentrate will wrap the foliar fertilizer particles to affect the dissolution effect, and then pour pyraclostrobin and other products.
3. We know that pyraclostrobin is highly permeable, and adding silicone has a poor effect, so it is best not to add it.
4. When pyraclostrobin is mixed with brassinolide, it is best to dilute it first and then mix it together.
5. Do not mix pyraclostrobin with strong oxidizing pesticides such as potassium permanganate, hydrogen peroxide, peracetic acid, chlorobromide and the like.
6. When compounded with triazole fungicides, the effect is still very good, which can improve the efficacy. Although pyraclostrobin's systemic conductivity is not as good as myclostrobin, pyraclostrobin's permeability is very strong, so do not mix it with copper preparations and strong oxidizing products when mixing.
7. When using pyraclostrobin, there is basically no need to consider the problem of phytotoxicity. It can be used with basic dilution, and phytotoxicity rarely occurs.
8. Not causing phytotoxicity does not mean that it can be used at will. Only scientific and correct use of pyraclostrobin can achieve the best effect!
To achieve good results, you must choose the right concentration and period. Don't use the drug blindly, which will not only have poor effects but also delay the timing and cause losses! It can not only be used as a fungicide, but also promote crop growth and strengthen the swelling of young fruits. When used in field crops, it can increase production and income, strengthen and improve effective ears (pods), enhance stress resistance, etc., especially when used in combination with potassium dihydrogen phosphate, the effect is outstanding.
