How to control rice borer

The netizen Yeshan Juvenile sent an e-mail on July 4th: I am a staff member of the township agricultural technology station. Now we have too many rice borer bugs here. I let the farmers use mad killing and dimethoate. The results reflect poor control of borers. Excuse me, what methods should be used to control borers?

A: The three maggots, rice borer borer, rice borer borer, and large borer borer, are commonly known as borers. For the control of rice borers, they should be used before the larval borer enters the rice plant. Generally, they are applied during the hatching period of eggs and the larvae The application of pesticides after entering the rice plant is often poor.

At present, most of the dead rice stems are stem borer, which has the habit of transforming the plant. One larvae can cause multiple stems and stems to die.

Prevention and control of cicada spasmorrhoids, application of drugs in the hatching period of eggs, application of chlorpyrifos, avermectin and its commonly used drugs with insecticidal formulations and other commonly used drugs, there is a good control effect, the application of diazinon, butene fluoride Nitrile (similar to fipronil is one of the best drugs for the control of stem borer), chlorantraniliprole, flubendiamide, and metaflumizone also have good control effects. Among them, diazinon, butene fipronil, chlorantraniliprole, and flubendiamide have good internal absorption conductivity. In the absence of appropriate control period, the worms have been drilled into rice leaf sheaths and other sites. The medicine also has better control effect and can effectively reduce the damage of the transgenic strains.

Choose fruits made from fleshy, succulent and naturally ripe fresh fruits with authentic flavors and aromas. Independent small package, easy to eat, convenient to store, can be described as the first choice for small snacks in the office. Not only that, the dried fruit is also beneficial to the stomach, vomiting, and anti-halation effects. It is really a small snack.
