The corn worm is a common corn worm. Although it looks very inconspicuous, it seriously affects the growth of corn worms. Chemical control is the main way to cure corn worms. Let's take a look at it. Let's go.
1. Both field and laboratory experiments have proved that the organophosphorus pesticides phoxim and chlorpyrifos have good effects on the control of the genus Spodoptera, while the beta-cypermethrin alone has a poor effect. When used, it should be mixed with avermectin to improve the control effect.
2. In the re-emergence field, 50% phoxim 15kg/hm2 can be watered with water, and the control effect is best; the seedling effect is better in the seeding ditch of the phoxim poisonous soil before seeding.
3. After the hazard occurs after the sowing, the poisonous soil, the bait can be used to protect the seedlings or the organophosphorus pesticides can be applied to the roots to protect the seedlings. The effect is better than the whole field spray, and the dosage is less and environmentally friendly.
In the field where the herbicide nicosulfuron has been used, it is necessary to avoid the use of organophosphorus pesticides. If it is necessary to use, make sure that the interval between the two uses is more than 7 days, and avoid spraying on the corn leaves when applying.
The above is the control method of corn two-pointed moth, more pesticide knowledge, please pay attention to China's pesticide network
