Meadow is a kind of invasive pest from abroad, which does great harm to corn and other food crops. So what kind of medicine does corn grass greedy night E use?

What kind of medicine does corn grass greedy night moth use?

Low toxicity and high efficiency, low residue, short residue time and pollution-free pesticide are the first choice for the pesticide control of meadow moth. The method of chemical control is that when the eggs of the night moth have just hatched into ants, the following chemicals can be sprayed on the grass of the corn field:

1. Spray corn leaves evenly with 10% cypermethrin EC 1200-1600 times solution.

two。 Using 5% cypermethrin EC 1200-1600 times solution, the stems and leaves of maize plants were uniformly sprayed.

3. Use 25% diflubenzuron 3 suspension 1600-2000 times solution foliar spray.

4. Spray corn leaves with 1500-2000 times solution of 25% thiazinone wettable powder.

5. Foliar spray with 4000 times solution of imidacloprid wettable powder.

6. 90% crystal trichlorfon 1000-2000 times solution was used to spray evenly on the leaf surface of corn. ⑦ uses 2.5% deltamethrin EC 3000 to 4000 times solution foliar spray.

II. Biological control

The trapping black light was used to trap and kill the adults of Spodoptera litura in corn field. At present, there are many kinds of black light, no matter which product, it is very effective to kill the adults of Spodoptera litura. An adult of Spodoptera litura can lay thousands or even tens of thousands of eggs and reproduce quickly, resulting in high density of larvae, many worms and great harm. Therefore, making use of the phototaxis characteristics of Spodoptera litura and using night light to trap and kill adults is the best and most ideal control method to control Spodoptera litura. It has high control efficiency, good effect, will not pollute the environment, destroy the environment, green environmental protection, economic benefits, convenient and fast, time-saving and labor-saving.

At present, there are only two ways of prevention and control, the use of black light to trap and kill adults, and the use of low-toxic, efficient and harmless agents to kill larvae.
