Pepper is in great demand in our country, and the planting area is also very wide, but in the planting process of farmers, pepper trees are prone to worms, what should we do?

First, what about the pepper tree worm?

If there is cotton bollworm, you can use matrine, rotenone, imidacloprid and other agents to control; if it is tobacco green worm, before its 3-year-old, spray imidacloprid, thiazide, thiazide and other agents; if it is a small land tiger, use thiazide, thiamethamide, deltamethrin and other agents; if aphids, you can use imidacloprid, deltamethrin, acetamiprid and other control.

Second, what are the symptoms of pepper pests?

1. Cotton bollworm

Larvae mainly eat fruit, but also harm tender stems, leaves and buds; damage to buds and flowers can cause a large number of buds and flowers; larvae drill into the fruit to eat pulp, resulting in fruit decay and a large number of fruit drops, which is easy to induce soft rot.

two。 Tobacco green worm

Tobacco green worm is a carnivorous pest on chili. Its two front chest hairs are connected away from the lower edge of the valve, and the body surface is short and obtuse. The larvae mainly eat the buds, flowers and fruits of the host, resulting in bud drop, fruit drop or insect fruit rot. If not controlled, the rate of fruit decay can reach 30%, and the rate as high as 80%. Sometimes it can also harm young leaves and stems and make holes.

3. Small land tiger

The adults and nymphs inhabit on the back of the leaves and on the tender shoots and stems to suck the juice. After the young leaves and growing points of pepper seedlings were killed, the leaves curled up. When the damage is serious, the whole leaf curls up and the growth stagnates. The whole plant wilted and died.

4. Thrips

Adults and nymphs do harm to leaves, buds and young fruits. After the injury, the young leaves atrophied and deformed, the growth of branches and lateral branches stagnated, and the fruit stalks, leaves and fruit epidermis turned brown.

5. Bemisia Tabaci

Pepper leaves gradually wilted to death, polluting pepper leaves and fruits, affecting the growth of pepper.

6. Spodoptera exigua

When the larvae nibble or strip away the leaves, the young larvae often cluster to form a net in the heart leaves, and then disperse the leaves.

Whether it is pepper pest or Fusarium wilt, bacterial wilt and other diseases, it should be controlled in time, otherwise it will lead to the decline of pepper yield or plant death.
