The major vegetable farms are widely used to prevent the beet night moth of the special drug, will be bromine, insects mixed spraying effect is very good, the disadvantage is a little expensive. Generally used when the effect is particularly serious and difficult to control. Botrytis cinerea (BT) is also very good, but the effect is slow, so you need to use the drug in advance. Otherwise there are too many substandard fruits and vegetables, which can cause financial losses. Methanosporium and its hybrid wormwood preparations can be used interchangeably to treat both the oblique nightshade moths and the small moths, and are also very effective on the higher larvae. Night moths, as the name suggests, prefer to feed in dull, damp conditions and are more active at night, so choosing a good time of day to spray will have a greater effect on prevention. After the sun goes down in the afternoon or before the sun comes up in the morning, in order to effectively kill the beet night moth prime time.

Now that the farming season is over, these folks are thinking about what seeds to plant next year. Corn, soybeans and peanuts can be planted. In past years, some corn, soybeans and some peanuts were also planted, in which the beet nightshade moth on peanuts became less and less effective as farmers responded to the more serious and commonly used insecticides in the area. There are many insecticides on the market for beet nightshade control, the more commonly used are agents such as metribuzin, chlorpyrifos, zunginitril, and cordyceps. But there is a problem. As metribuzin, the ones currently on the market vary quite a bit from manufacturer to manufacturer in terms of content and quality. The effect is very average and ineffective if you do not buy it. Some insecticides are more locally resistant and generally ineffective. Methoprene, chlorpyrifos or other insecticides may also be resistant. To solve the problem, you can change the agent or use a combination of chlorpyrifos, benzamide and metribuzin.

Beet nightshade is already a southern pest, so the overwintering soil layer is shallow, and can be supplemented by reducing it through fall and winter irrigation. Adults can be attracted by black lights and soupy liquids. Utilizing its pseudo-death, you can catch the truele, larvae or eggs at night or during the main meal. Timely prevention and treatment. Beet nightshade moths are afraid of light and come out during the day and at night, so prevention time is best chosen before 9336030 minutes in the morning or after 17336000 points in the afternoon. At the same time, the resistance of the larvae over 3 years old is significantly higher, and the prevention and treatment should focus on killing before 3 years old.

You can choose 50% phoxim emulsion 1000 times, 20% Xi'an polyurethane emulsion 2000~3000 times, 2.5% bromine cyanide emulsion 3000 times. Insect growth regulators, also known as insect chitin synthesis inhibitors, can be used. Domestic perchloroethylene urea 1 (also known as compound charging insects, deworming, flurorin, isoflurane, red perchloroethylene) or digestive oil urea 3 (also known as small urea 1) 20% or 25% binder.
