In recent years, the return rate of the vegetable market is getting better and better, farmers are more focused on fine cultivation, but the diagnosis and control of many diseases and insect pests are often helpless, the following is a small editor to sort out some common vegetable pests HD map, I hope to help you.
Underground pests
Caddisflies: Multi-food, harmful to various vegetables.
Control method: Before sowing, use octyl thion to mix seeds, the amount of seed mixing is 0.1% to 0.3% of the weight of the seeds, and sown after drying.
Poison bait trap: 90% crystal enemy insect 1kg with 60 ~ 70 ° C appropriate amount of warm water dissolved into a liquid medicine, or 50% diazine emulsion 1kg, or 50% octylthion emulsion 1kg diluted with water about 5 times, and then with 30 ~ 50kg of stir-fried wheat bran or bean cake or cottonseed cake or cooked semi-cooked grain, etc. Mix well, mix with an appropriate amount of water, mix the tide is appropriate, make poison bait. 3 to 5 kg of poison bait per acre can be applied into the field to trap the cadavers, and 25% high chlorine octyl thiophos emulsion 1500 times liquid can also be used to fill the hole to control insects.

Sprinkle poisonous soil: sprinkle the ground with 2.3% cypermethrin mixed with soil, and use 50 to 100g per mu of medicine. 2. Ground spray: 2.5% high efficiency cypermethrin emulsion 4000 times liquid or 25% high chlorine octylthion emulsion 1500 times liquid.
Leaf-eating pests

Control methods: 5% methylaminoavermectin benzoate microemulsion 3-5ml/mu (beet nocturnal moth doubled) can be used to mix 30-50kg of water, or 2.5% high-efficiency cypermethrin 2000 times liquid 30-60ml/mu, mixed with water 40-50kg.
Red-edged lamp moth, human-patterned lamp moth (red-bellied white light moth): it is harmful to cabbage, pepper, eggplant, shallots, melons, cruciferous vegetables.
Control method: 2.5% high-efficiency cypermethrin emulsion 2000~3000 times liquid, or 25% high-chlorine octylthion emulsion 1000~1500 times liquid spray.
Potato ladybug (potato twenty-eight star ladybird), eggplant twenty-eight star ladybird: for potatoes and other solanaceous vegetables, legumes, melons, cabbage and other vegetables.

Yellow curly stripe vegetable jumping nails, yellow broad stripe jumping nails, yellow narrow stripe vegetable jumping nails, yellow straight stripe vegetable jumping nails, healing leaf nails: for the harm of cruciferous vegetables and eggplant fruits, melons, beans, leeks, shallots, garlic, cabbage and other vegetables.
Control methods: General adult insects can choose 2.5% high-efficiency cypermethrin emulsion 4000 times liquid, or 25% high chlorine octylthion emulsion 1500 times liquid, or 5% acetamidine emulsion 20-30ml/mu spray. The larvae can choose 2.5% cypermethrin emulsion and 4.5% high-efficiency cypermethrin emulsion, which has a better effect.
Yellow-winged leaf bee (turnip leaf bee): A cruciferous vegetable.
Control method: 2.5% high-efficiency cyfluthrin emulsion 4000 times liquid, or 25% high chlorine octylthion emulsion 1500 times liquid spray can be used.
Large green leafhopper, cotton leafhopper, small green leafhopper: harmful to cruciferous, leguminous, nightshade, spinach, celery, lettuce, carrots and other vegetables.
Control methods: 5% methylaminoavermectin benzoate microemulsion 4-6ml/mu, or 5% acetamidine emulsion 20-30ml/mu, or 20% imidacloprid solution 10-15ml/mu, mixed with water 50kg spray.

Remarks: Because of the large number of aphids propagating algebra, the harm to crops is widespread, and after the aphids harm the crops, there will be residual honeydew, and the agent is difficult to attach to the insect body, etc., causing the aphids to be very difficult to fight and the resistance is very serious. Now, the use of a single agent, such as imidacloprid, acetamiprid, pyridone, alenoxazine, etc. has been difficult to control, so now the basic effect is a variety of drugs mixed. For example: avermectin + alenophexamine + pyritone; cis cypermethrin + pyritone + imidacloprid and so on.
Whitefly (greenhouse whitefly, tobacco lice): harmful cucumbers, tomatoes, cabbage, eggplant, beans, celery, green onions, etc.
Control method: 5% acetamidine emulsion can be used 20-30ml/mu, or 20% imidacloprid solution 15-30ml/mu, mixed with water 50-60kg spray.
Note: Every year from the end of July to the end of September, whitefly appear in the open field and cold sheds, there will be a peak period of harm. At present, the prevention effect of single dose in many areas is not good, so it is necessary to mix compound preparations and use them together.
Bug pests (vegetable bugs, spotted bugs): It is a variety of vegetables such as cruciferous, legumes, and green onions that harm radishes and cabbage.
Prevention and control methods: 25% high-chlorine octylthiophos emulsion 1000 to 1500 times liquid, or 2.5% high-efficiency cypermethrin emulsion 3000 to 4000 times liquid spray.
Thrips pests (palm thrips, flower thrips, shallot thrips): spinach, beans, winter melon, eggplant, tomatoes, legumes, cruciferous, green onions, onions, garlic, leeks, etc.
Note: This year, thrips pests are particularly harmful. Many people respond that thrips are more difficult to fight and have developed severe resistance. Therefore, it is recommended to compound and alternate the above agents. (For example, the use of ethyl polybactericide + acetamiprid, spirant ethyl ester + imidacloprid, bifenthrin + thiamethiazide and other compound use.) ）
Submerged flies (American spotted diving flies, South American spotted diving flies, melon spotted diving flies, allium spotted leaf diving flies, Liquan flies, spinach spring flies, rape leafminer flies): for the pest of melons, nightshade fruits, legumes, cruciferous family, artemisia, lettuce and other vegetables.

Mites
Cotton red leaf mite (cinnabar leaf mite), truncated leaf mite, tea yellow mite (side multi-food tarsal mite): mainly harmful melons, eggplant fruits, melons, legumes, cruciferous family, umbelliferous family and other vegetables.
Remarks: The key to the control of mite pests is also to alternate medication, pay attention to the double killing of insects and eggs when killing insects (such as egg killing, spirospiter for larvae, acetazole compound with alkyne mites that kill adult insects, avermectin, etc.), improve prevention efficiency, and slow down drug resistance.
Other leaf-eating pests
Coriander (coriander): mainly harmful legumes vegetables, the leaves are harmful solanaceae, cabbage, amaranth and so on.
Prevention and control methods: 2.5% high-efficiency cyfluthrin emulsion 2000-3000 times liquid or 25% high chlorine octylthion emulsion 1500 times liquid spray can be used.
Small reminder
The key to slowing the development of pest resistance is to master the correct method of medication and pay attention to alternate rotations. In this way, insect prevention and treatment can be more efficient!
