After the Spring Festival, the weather became warmer and various pests in the protected areas gradually increased. Especially after the convulsions (March 6), wild pests began to appear. Therefore, at this time, we must seize the favorable opportunity to control pests, take precautions, and prevent pests in the greenhouse.

Leafhoppers gradually increase, multiply quickly and are difficult to control. The victim's leaf curling and hardening, premature yellowing, and photosynthesis are greatly affected. The skin of the victim fruit is dull, and the commerciality is reduced. Alternative acaricides can be used alternately. It is recommended to use guaiac, broom, nisren, avermectin. The avermectin killing effect is good and the insecticide has a broad spectrum, especially for the control of the two-leafhopper. Nisolo has a good effect in killing eggs and cubs.

Whitefly appears in large numbers in early spring sheds, sucking plant sap and contaminating plants with honeydew, which can easily cause coal pollution. At the same time, whiteflies are also susceptible to transmission of viral diseases when they suck sap and cause greater losses. For example, type B Bemisia tabaci can transmit the tomato TY virus. Therefore, prevention and control of shed powder can not be delayed. Imidacloprid to kill adult worms is effective, and buprofimazine is good at killing eggs. acetamiprid kills both worms and kills eggs. It is recommended to use acetamiprid and Aketai mixture to spray on sunny morning morning, and then use different drugs. Proweed smoked sheds at night. These agents also have a good effect on the newly hatched aphids.

Thrips smoked young leaves, flowers and young fruit, easily lead to early fall flowers, leaves withered, skin shrinkage, and more latent in the bottom of plants or flowers, control difficulties. It is recommended to use spinosad, cyfluthrin (Kung Fu), and acetamiprid, thiamethoxam, nitenpyram, avermectin, etc. to spray medicine in the evening or low light, focusing on flower and leaves. Back to the growing point, and medication. With the night smoked shed, the effect is good.

Leaf miner larvae sneak into the leaf epidermis of plant leaves to feed on the leaf, leaving irregular gray and white long lines on the leaves, which seriously cause the leaves to wither and die. You can use ciprofloxacin (milk), diflubenzuron, avermectin, etc., pay attention to alternate use.

In addition, pests can be controlled through some physical measures. For example, 10 cm above the top of the greenhouse crop, yellow sticky board is suspended, 30-40 pieces of mu are hung to kill whitefly, aphids, leaf miners, etc.; 30-40 pieces of blue armyworm board are set near the ground. To kill the thrips. In addition, a 40-mesh insect net is set at the air outlet on the shed to prevent pest invasion outside the shed. After the temperature rises in May, it will be removed.
