CAS:14698-29-4丨Oxolinic Acid

Quinolinone fungicides, used for rice seed treatment, known as the first fungicide with a strong effect on rice refractory bacterial blight (seedling rot). The occurrence of bacterial blight can be inhibited by the treatment of seed mixing with chemicals before sowing, and then the occurrence of bacterial blight can be prevented by transplanting the healthy seedlings to Honda. The mechanism of action is that it has a wide range of antibacterial activity against Gram-negative bacteria, but has weak activity against Gram-positive bacteria and no activity against fungi. By inhibiting the synthesis of DNA, it prevents the bacteria from dividing and multiplying. In bacterial bacteria, A reverse supercurling enzyme is introduced to the supercurling structure of DNA. This agent can bind to the subgroup A of this enzyme, thereby suppressing the function of the Chemicalbook and making the DNA unable to replicate and causing death soon. The seed was impregnated with 1000g/mL for 24h, 1000g/mL for 10min, or coated with 20% wettable powder with 0.5% seed mass. The control effect was more than 97%. This product can also be used to control rice grain rot, potato black cavity disease, soft rot, fire blight and similar diseases. If 300 ~ 600g of active ingredient /hm2 was applied on the leaf surface at heading stage, grain rot could be controlled. Fire blight and soft rot of apple and pear can be controlled by spraying with 300 ~ 600g active ingredient /hm2 leaf surface. It also has good protective and therapeutic effects on cabbage soft rot.
