May I ask what medicine is good for thrips to die, thank you.

The key to preventing and controlling thrips harm is to master the following points: First, spraying in the evening has the best control effect. The second is to choose the agent:

Bifenthrin, dinotefuran, ethyl spinosadin, ammetine (20% carbosulfan), thiamethoxam, add soft water (agricultural water quality optimizer) before dispensing to improve adhesion, increase ductility, enhance permeability, and the effect is better.

Deltamethrin, imidacloprid, acetamiprid or cypermethrin can kill thrips completely.

The prevention and control methods are as follows:

1. Adjust the medication: It is a very light-sensitive insect, and it will drill out at night to harm the plant, so the spraying should be in the evening, and the effect of spraying at this time will be much better.

2. Medication method: When spraying drugs, spray the plants evenly first, and then spray some on the ground, so as to avoid it from climbing onto the plants.

4. Pay attention to prevention: In the process of crop planting to flowering, it should be prevented by using pesticides in time, and its phototaxis can also be used to hang blue plates, which can also reduce its damage to crops in the later stage.

A large number of "thrips" appear in the pot, how to eliminate it without "chemicals", ask for help!

In addition to thrips, it is recommended to use the Juying of Guangdong Plant Dragon Company, which is an ultra-efficient, low-residue biological pesticide developed by emamectin benzoate transformation, especially excellent performance of resistant thrips, after application, it can quickly kill pests, safe and harmless, suitable for rice, vegetables, peanuts, corn, soybeans, tobacco, cotton, pears, apples, grapes, bananas, mangoes, longans, lychees and other crops of thrips, lepidopteran pest control.

In addition, it is necessary to say a little more, thrips should be prevented in advance, and do not wait until it is overflowing to ask how to use medicine to get rid of thrips. In early spring, weeds and dead branches and leaves should be removed from the field, and burned or buried deep to eliminate overwintering adults and nymphs. Strengthen fertilizer and water management to promote the growth of plants and reduce damage.

Thrips will suck the sap of new leaves, young shoots, young fruits, etc., and once infected, the plant will be stunted, and the leaves are prone to curling, hardening, and slow growth, which will eventually affect the yield and quality. Therefore, it is necessary to treat it in time when it is found. In the case of protected thrips, a combination of smoke shed and foliar spray can be used.

In the open field, a combination of above-ground and underground methods are used, and pesticides are sprayed when watering. You can choose basal aphids, 30-50 ml mixed with a bucket of water, sprayed.

Thrips is a general term for the insect class Tasseloptera. The larvae are white, yellow, or orange, and the adults are yellow, brown, or black; Feed on plant sap or fungus. The body is tiny, with a body length of 7 mm, rarely exceeding 7 mm.

Thripidae belongs to the general family Thripoidea of the order Thysanoptera, and more than 2,000 species in 276 genera are known worldwide, including 4 subfamilies of Panchaetothripinae, Dendrothripinae, Sericothitripinae and Thripinae. Insects of this family are widely distributed all over the world, and their feeding habits are complex, mainly including herbivorous, fungivorous and predatory, of which phytophagous accounts for more than half, and is one of the important economic pests.

Biologics that dissolve worms can be tried. Dissolve insects.

I have a biological agent here, which is configured with vegetable oil, no drug damage, good effect, and the effect can reach more than half a month, I don't know if you are interested?

1. Rice seedling stage: If the rice seedling stage is infected with the harm of thrips, it is recommended to use thiamethoxam varieties, specifically choose Braim 35% thiamethoxam suspension seed coating agent, dilute and spray on the rice leaves, pay attention to the front and back to spray, so that it can be effective.

2. Vegetables: If the cultivated vegetables are infected with thrips, the roots can be irrigated with 25% thiamethoxam water dispersible granules 3000-5000 times, which can not only reduce viral diseases, but also reduce the harm of other underground pests.

3. Tobacco: If tobacco crops are infected with thrips, 1000 times of 25% imidacloprid or 3000-5000 times of 25% thiamethoxam. In addition, to prevent it in advance, you can use medicine to irrigate the roots when transplanting.

4. Fruit trees: mango in fruit trees is the most serious, you can spray 25% thiamethoxam, pay attention to the need to increase the amount of use, you can use 800 times spray, but also mix avermectin barrels to mix.

In addition to spraying drugs, thrips should also be strengthened in management. Weeds should be removed from the field frequently to reduce the source of insects. It is also necessary to strengthen the management of fertilizer and water to promote the growth of crops and plants, so as to improve disease resistance.

In addition, physical control methods can also be used, taking advantage of its bluish habit, a blue sticky board can be set up, so that adult insects can be trapped.

1. What medicine works best for the manuscript.

1.Rice seedling stage: If the rice seedling stage is infected with thrips, it is recommended to use thiamethoxam varieties, which can choose berry 35% thiamethoxam suspension seed coating agent, diluted and sprayed on rice leaves.

Pay attention to both sides so that you can achieve the effect. 2.Vegetables:

If cultivated vegetables are infected with thrips, 25% thiamethoxam water dispersible granules can be used to irrigate the roots 3000-5000 times, which can not only reduce viral diseases, but also reduce the harm of other underground pests. 3.Tobacco:

If tobacco crops are infected with thrips, 1000 times 25% imidacloprid or 3000-5000 times 25% thiamethoxam can be used. In addition, to prevent it in advance, you can carry out medicated root irrigation at the time of transplanting. 4.

Fruit trees: Mango is the most harmful among fruit trees, and can be sprayed with 25% thiamethoxam on large bulls. Note that to increase the dosage, you can spray 800 times, mix with avermectin barrels.

Second, how to prevent and control.

In addition to spraying the drug, the management of thrips should be strengthened. Usually remove weeds in the field frequently to reduce the source of insects. It is also necessary to strengthen fertilizer and water management to make crops and plants thrive, thereby improving disease resistance.

In addition, you can also use the method of physical control, and use its blue habit to set up a blue sticky board, so as to trap and kill adult insects.
