<h1 class= "article-title" > sucking and licking and filing pests</h1>
Leafhoppers [large green leafhoppers, cotton leafhoppers, small green leafhoppers]: for the harm of cruciferous, legumes, 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.

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 single use of single agent in many places has not been effective, so it is necessary to mix compound preparations together.
Bug pests [vegetable bugs, spotted bugs]: it is harmful to radish, cabbage and other cruciferous, legumes, green onions and other vegetables.

Note: This year, thrips are particularly harmful (from the end of June to now, there have been thrips hazards). Many people react that thrips are more difficult to beat and have developed severe resistance. Therefore, it is recommended to compound and alternate the use of 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 diver, South American spotted fly, melon spotted fly (tomato spotted fly), allium spotted fly (allium leaf diver fly), allium leaf diver fly, Li quan fly (spinach leafminer fly), spinach spring fly (spinach leafmine fly), rape leaf diver fly (pea leaf diver fly)]: for the harm of melons, nightshade fruits, legumes, cruciferous family, artemisia, lettuce and other vegetables.

<h1 class="article-title" > mite class</h1>
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 and other vegetables.
Remarks: The degree of resistance of mite pests is basically from north to south, and the resistance gradually increases. 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, spironyl esters for larvae, acetazole compound with alkyne mites that kill adult insects, avermectin, etc.), improve prevention and control, and slow down drug resistance.

<h1 class="article-title" > other leaf-eating pests</h1>
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.
Snails: Multi-food, harmful legumes, cruciferous and solanaceous vegetables.
Prevention and control methods: 1. Sprinkle lime belt 5-7.5kg/mu; 2. Can be sprayed with 800 times copper sulfate liquid or 1% salt water or 8% polyacetaldehyde 800-1000 times liquid.
Finally, it should be emphasized that the key to slowing down the resistance of pests is to master the correct method of medication and pay attention to alternate rotations. (Pesticide updates are very slow, it is impossible for this drug to become resistant, and the next agent can be developed immediately.) All we have to do is try to use the drug as long as possible.
So
Everyone must have the awareness of alternating and rotating medications,
In this way, we can prevent and treat insects more efficiently!
