CYAZOFAMID - Application
Open Data Verified Data
sulfonamides and imidazoles. The oomycetes fungi such as Phytophthora, Frost mold, false Frost mold, rot mold, and rhizome of Brassica rhizome has high biological activity. It can block the electron transfer of mitochondrial cytochrome bc. Complex in oomycetes to interfere with the supply of energy, and its binding site is the Q, center of the enzyme.

| use | sulfamidazole fungicides. It has high biological activity against oomycetes such as Phytophthora, Frost Mold, Pseudofrost Mold, Pythium and Brassica rhizoma of Rhizoma Brassica. The mechanism of action is to block the electron transfer of the mitochondrial cytochrome bc1 complex in the oomycetes to interfere with the supply of energy. The binding site is the Q1 center of the enzyme and has no cross resistance with other fungicides. Its high selective activity to pathogenic bacteria may be caused by the difference in sensitivity of target enzymes to drugs. Field application has extremely high control effect on late blight and downy mildew, and the dosage is 2-38 times lower than other fungicides. For example, the treatment of potato late blight at a concentration of 50-100mg/L has outstanding control effect, and the medication period is flexible., Long lasting period. Treating downy mildew of grapes, cucumbers and melons with the same concentration also has excellent control effect. The agent can prolong the growth time of crops and increase production and income. It can improve the quality of tomatoes. The number of times of use shall not exceed 4, and the method of use shall be foliar spray. At the treatment concentration 4 times higher than the actual dosage, no drug damage was reported. At present, the control targets are being expanded, including sweet pepper blight, watermelon cotton rot, downy mildew of large white disease, downy mildew of onion and other diseases. |
| Production method | Using 4-methylacetophenone as a raw material, it is first chlorinated, then condensed with hydroxylamine, and cyclized with glyoxal to produce an intermediate Substituted imidazole; then chlorinated and dehydrated to obtain intermediate substituted cyanoimidazole, and finally reacted with dimethylaminosulfonyl chloride to obtain cyanoidazole. |
