Stability: the pH value was 7 and the pH value was 9 for 12 days without hydrolysis. 3, chemical structure
Application: This product is triazole fungicide, on a series of cereal crops such as blight, powdery mildew, eye disease and other 10 kinds of disease has a good effect in the prevention and treatment, and prevention of sugar beet, peanut, rapeseed, lawn, coffee, rice and fruit trees, and disease. Not only has a good protection, treatment and eradication of the activity, but also has an internal suction and a better residual activity. Role characteristics and uses: epoxiconazole is a suction triazole fungicides, the active ingredient of epoxiconazole inhibits fungal ergosterol synthesis, hindering the formation of cell wall of bacteria and epoxiconazole molecules of a fungal enzyme (14-dencthylase) have a strong affinity, and currently known fungicide, compared to more effective inhibition of bacteria pathogens. Epoxiconazole can improve crop of chitinase activity and lead to contraction of the fungal haustoria, inhibit the germs, which is epoxiconazole in all triazole products unique characteristics. Of banana, onion and garlic, celery, beans, melons, asparagus, peanuts, sugar beet, etc. crop leaf spot disease, powdery mildew, rust and grape anthracnose, white rot disease has good control effect. This product is strong absorption, can quickly be plant absorption and transmission to susceptible sites, immediately stop the disease infection, local pesticide control thoroughly. The effective period is excellent, such as the antimicrobial effect of the grain can reach more than 40 days, excellent retention effect, reduce the number of times and labor costs and labor costs. Not only can effectively control the disease, but also improve the Biochemical Resistance of crops by regulating the activity of enzyme, so that the disease resistance of the crop is greatly enhanced.
So that the leaf color is more green, so as to ensure maximum photosynthesis, improve yield and improve the quality of the leaf.
Epoxiconazole on a series of cereal crop diseases such as more than 10 kinds of blight, powdery mildew, eye disease and other diseases have very good control effect, and prevention of sugar beet, peanut, rapeseed, lawn, coffee, rice and fruit trees, and disease. It not only has a very good protection, treatment and eradication of the activity, but also has an internal suction and a better residual activity, the use of the dose is usually 75 to 125 grams of active ingredients / ha, spray treatment. Formulations: 12.5% epoxiconazole SC, 7. 5% fluorine Difenoconazole EC production method: using fluorobenzene, O-chloro benzyl chloride as starting materials, synthesis of 1 - (o-chlorophenyl) - 2 - (4-fluorophenyl) - propylene and after bromination with NBS, ring re oxidation. Finally, and H-1, 2, 4 - triazole condensation get the final product, or 1 - (o-chlorophenyl) 2 (of fluorine phenyl) - propylene through bromination with NBS, and H-1, 2, triazole condensation, the epoxidation get end products.
