Grasping the three-point greenhouse to prevent insects
Due to the temperate climate and abundant food in summer, various pests are prone to outbreaks and floods. For the prevention and control of pests, in addition to setting up insect nets, hanging sticky insect boards, insecticidal lamps, etc.
In view of the summer climate characteristics, the author suggests that the vegetable farmers should grasp the following three points, which can make the insect control achieve the effect of “doing twice the result with half the effortâ€.
Eliminate weeds to reduce insect sources and sources
In the summer, the lush weeds inside and outside the shed are not only a good place for pests to “hidden to hideâ€, but also the habitats where various pests mate and multiply. The pests move to the shed through these weeds, which are harmful to vegetable plants and can spread more. A pathogen that causes a viral disease or a bacterial disease.
Therefore, eradicating weeds around the greenhouse, removing the habitat of pests, reducing the probability of pests moving back and forth, can greatly reduce the source of insects and bacteria, and improve the insect control effect.
Choosing the medicinal eggs
In the prevention and control of pests, vegetable farmers know that prevention should be carried out in advance, but once pests appear in the shed, many vegetable farmers usually only pay attention to the prevention and control of adults and neglect the prevention and treatment of eggs, which is also a cause of the "recurrent attacks" of pests.
Therefore, it is recommended that vegetable farmers choose compounding or compounding agents for insecticides, such as the control of whitefly, and the use of acetamiprid mixed with buprofezin to kill insects and eggs for control; and control of thrips with fipronil and polychlortetracycline, insects The egg is killed and the insect control effect is greatly improved.
Rational use of drugs to improve control
Many vegetable farmers have reported that some insecticides have a good insecticidal effect, but it is not long before pests are “returningâ€, which has a lot to do with the lack of comprehensive spraying of vegetable farmers. For example, Hummer likes to hide in leaf back, flowers or ground soil. In the middle, it is not easy to be found. If the spray only sprays the leaf surface, how can the Hummer prevent it?
Therefore, the vegetable farmers should spray the medicine on the front and back, flowers, stems, and surface of the plant, and spray evenly to ensure the insect-proof effect. In addition, even if the anti-insect effect is very good, do not use it for a long time. Otherwise, the pest will gradually become resistant to the agent and reduce the control effect. It is recommended that the vegetable farmers alternate the rotation of the pesticide.
