The phytosanitary doctor sent an e-mail: There are fireflies (rushes) in the paddy rice fields.
Answer: When rice seedlings exceed the four-leaf stage, they can be treated with flufenazone or chlorflumizole plus 2% 4-chlorochloride.
Tip: If the seedlings are small, they can be treated with pyrazosulfuron spray first. At present, some areas of the firefly have already produced strong resistance to bensulfuron-methyl and pyrazosulfuron-methyl. When the effect of pyrazosulfuron-methyl is not good, it can be controlled by adding 2-aza-4-chloropyrazine. Fluoxazone has a good killing effect on the aerial parts of the fireflies, and the speed of weed control is fast. Weeds die after 2 days of application, and the addition of 2A and 4C is beneficial for grass roots. Exterminate. A sufficient amount of water should be added when spraying carbamoyl, otherwise burn spots may be generated on rice leaves (the damaged seedlings generally recover quickly).
