Fungal diseases are the most diverse class of diseases, the choice of efficient fungicides is the hope of farmers, today I would like to introduce you to an excellent fungicide – pyrimethanil, the drug can control almost all fungus-induced diseases, and has a variety of functions of protection and treatment eradication, known as ” Universal fungicide”, is currently the most widely used a very good fungicide.
It is a broad-spectrum, high-efficiency fungicide with good systemic conductivity, strong penetration and long shelf-life, which can protect, treat and eradicate almost all fungal diseases. Seed treatment and soil treatment. There are more than 400 formulations registered in China’s Pesticide Inspection and Certification Institute, and it is one of the most registered fungicide varieties.
Main features
(1) Broad fungicidal spectrum: Pyrimethanil is a broad-spectrum fungicide that can be used to control almost all fungal diseases, and can be sprayed once to control dozens of diseases at the same time, greatly reducing the number of sprays.
(2) Strong penetration: Pyrimethanil has strong penetration, no need to add any penetrating agent when using, that is, it can penetrate across layers, only need to spray the back of the leaf, it can quickly penetrate into the back of the leaf, to achieve the prevention and control effect of positive hit and negative death.
(3) Good internal absorption and conduction: Pyrimethanil has strong internal absorption and conduction, and it can be absorbed by leaves, stalks and roots and conduction to all parts of the plant quickly after application, so it can be used not only for spraying, but also for seed treatment and soil treatment.
(4) Long shelf life: Pyrimethanil can be sprayed on leaves for 15 to 20 days, and seed and soil treatments for more than 50 days, which can greatly reduce the number of sprays.
(5) Good mixability: Pyrimethanil has good mixability and can be mixed with dozens of agents such as chlorothalonil, phenothixazole and enoxymorph, etc. The mixability not only delays the resistance of the fungus but also improves the control effect.
Applicable crops
Pyrimethanil has a wide range of disease control, and can be applied to wheat, corn, rice and other food crops, peanuts, cotton, sesame, tobacco and other cash crops, tomatoes, watermelons, cucumbers, eggplants, peppers and other vegetable crops, apples, pear trees, kiwis, mangoes, litchi, longan, bananas and other fruit trees, Chinese herbs, flowers and hundreds of other crops.
Preventing objects
It can be used to control early blight, late blight, gray mold, leaf mold, basal rot, downy mildew, epidemic disease, powdery mildew, anthracnose, gray fungus, black star, black pox, spike brown blight, white rot, sudden fall, leaf spot, blight, brown spot, yellow blight, leaf spot, fungal diseases such as fungal diseases, especially powdery mildew, rust, glume blight, net blight It is especially effective against powdery mildew, rust, cereal blight, net blotch, downy mildew, cranberry blight, late blight, rice blight and many other diseases. It can achieve the purpose of multi-treatment by one spray.
Use method
(1) Prevention and control of cucumber downy mildew, epidemic disease, anthracnose, black star disease and other diseases, can be used at the early stage of the disease, generally each mu each time available 25% pyrimethanil suspension 60 ~ 90 ml, mixed with water 30 ~ 50 kg of uniform spray, 1 ~ 2 days to better control the expansion of the above diseases.
(2) Prevention and control of rice blast, blight and other diseases, can be used before the onset or early onset of the disease, each mu each time with 25% suspension 20 ~ 40 ml, spray every 10 days, evenly sprayed 2 times, can quickly control the spread of the above diseases.
(3) Control watermelon wilt, anthracnose, vine blight and other diseases, can be used before or at the beginning of the disease, each mu each time with 50% water dispersible granules 30 ~ 50 grams, spray every 10 days, spray 2 ~ 3 times, can effectively prevent the occurrence of the above diseases and further damage.
Special reminder
Pyrimethanil is highly penetrating and systemic, so it is not necessary to add any adhesive or penetrating agent when using it, otherwise, it is easy to have drug damage.
Pyrimethanil should be used at seedling stage within 3 leaves as much as possible in seed dressing and not for spraying to avoid damage.
(3) Pyrimethanil should not be mixed with emulsifiable oil to avoid damage.
