Does insecticide kill red spiders alone? How to kill red spiders

Insecticides alone cannot kill spider mites.

Insecticidal monophyllum, which is an organic compound, is a white crystalline solid. It has stomach toxicity, contact killing and systemic conduction, and also has a certain fumigation effect. It is used to control rice leafhoppers, planthoppers, rice bracts, vegetable yellow-striped jumping beetles, cabbage insects, pear tree bifurcats, etc.

Insecticidal monolithic is an analogue of synthetic sand silkworm toxin, which enters the insect body and is quickly converted into sand silkworm toxin or dihydrosand silkworm toxin. The drug is a competitive inhibitor of acetylcholine, which has strong contact killing, gastric toxicity and systemic conduction effects, and has a good control effect on the larvae of lepidopteran pests. It is a bionic pesticide, which has little impact on natural enemies, no resistance, no residual toxicity, and does not pollute the environment, and is an ideal agent for comprehensive pest control.

The agent can effectively control a variety of pests on rice, vegetables, wheat, corn, tea, fruit trees and other crops, especially for rice leaf roller, two borer, three borer, etc. It has low toxicity to fish, but high toxicity to silkworms. In China, the registered crop is rice, which is used to control borers.

Not necessarily, it depends on the situation.

Grass ash insecticidal method: Grass ash can be used to control green onion flies, root maggots, aphids, beetles, etc. Spray plant ash liquid, soak 3 kg of plant ash in 10 kg of water for 3 days, spray plant ash leaching solution after filtering residue, spraying amount of 50 kg per mu.

Castor leaf insecticidal method: It can be used to control various pests, such as vegetable aphids, cabbage worms, fly maggots, ground tigers, beetles, diamondback moths, etc. You can add 3 - 5 times more water to the castor juice and spray it on the leaves after soaking for 12 hours.

Chili insecticidal method: take 500 grams of fresh chili peppers (the spicier the better), add 15 - 20 kg of water, boil for 10 - 15 minutes, filter out the juice, add 100 - 125 grams of laundry detergent while hot, add 50 kg of water to two bags of Meijia after cooling, mix well and spray. This method can be used to control corn borer, rice planthopper, rice borer, leaf roller, aphid, red spider, tiger and other pests.

The spotted fly, also known as the ghost charm, appears on the surface of the leaf with a series of twisted and irregular drawing marks. Avermectin, or Bacterin, or Flydom can be used. Insecticidal mono, or avermectin and myxamine mixture plus silicone spray control.

With silicone additives, the effect is better, so as to better exert the efficacy. Suggested medication: avermectin Fly Kill 30 (suspension) + silicone, the effect is very good.

If it is an outbreak period, grasp the number of days between injections, don't wait so long.

Spider mites can be killed with 75 of alcohol.

After getting the red roses, if there are only one or two pots, maintain them at home, and there are children at home, in this case, many flower gods do not recommend using pesticides to kill insects. It is safe and efficient to soak cigarette butts in concentrated water, wash clothes, detergent, alcohol, garlic water and other dilution sprays. However, if the pest infestation is too severe, frequent use will not work well.

Precautions for alcohol to kill rose red spiders.

1. The concentration should be low.

When using alcohol to kill spider spiders, you can't spray them directly with alcohol. If this concentration is too high, it is easy to burn the leaves, causing the leaves to fall off. Follow 1500 uses.

2. It cannot be sprayed back and forth.

When spraying, you can't spray back and forth, just once, just wet. Don't spray the wine and spray it again, just spray once, don't spray it a few times. The leaves of the moon flower are tender and weak.

3. Ventilation is not exposed to the sun.

When using alcohol spray to prevent and control spider mites, it is not suitable to expose to the sun, and the environment should be ventilated. Spray it again when the high temperature is cool at night, and the effect will be good overnight. Then, spray it with clean water and rinse it off the next morning. If it rains after spraying, you can't spray it immediately after the rain stops, and use it again the next day.

4.Don't do it too often.

There is also the alcohol spray that cannot be used too many times after controlling the spider mite, which severely hinders photosynthesis. Of course, too many times will make the same effect less effective than the red spider.

<> imidacloprid can control red spiders. Because the red spider mainly uses its mouthparts to suck the sap of the leaves, it can be absorbed into the body of the red spider after using imidacloprid. Spider mites usually hide on the back of the leaves of the plant, and must be sprayed on the back of the leaves when applying the agent in order to effectively kill the insect.

In addition to the use of drugs to kill insects, it is also necessary to provide a moist environment for the plants, which can also effectively control spider mites.

1. Can imidacloprid kill spider mites?

1. Imidacloprid can kill red spiders. Because the red spider sucks the leaf juice with its mouthparts, it will be absorbed into the red spider after spraying imidacloprid, and the red spider belongs to the acetylcholinesterase receptor, and the neurotoxin in the imidacloprid will act on the red spider to achieve the insecticidal effect.

2. Spider mites generally hide on the back of the leaves of the plant, so they must be sprayed on the back of the leaves when using the agent, so as to achieve an effective insecticidal effect. Generally, 3-5 times of continuous spraying of imidacloprid potion can achieve the visible insecticidal effect, note that when spraying the plant with the potion, you must wait until the afternoon to spray, at this time most of the red spiders will climb to the leaf surface, which can promote the effect of insecticide.

3. In addition to using drugs such as imidacloprid to kill insects, it is necessary to maintain a moist environment for the plants, which can also effectively prevent spider mites. Because spider mites are a pest that prefers a dry environment, rinsing the foliage with water can also destroy the dry environment that red spiders prefer, or use chili water to control spider mites.

2. Matters to be paid attention to when using imidacloprid

1. The safe interval between the use of imidacloprid on cabbage is about 14 days, and it can only be used twice a season.

2. Imidacloprid is toxic to people and animals, so you must wear protective equipment when using, you can not smoke and eat, and you must not apply pesticides to the wind, so as to avoid direct contact with the liquid medicine, prevent inhalation from the mouth and nose, and wash your hands, face and contaminated parts of the body and clothes after application.

3. The agent can be used in rotation with other pesticides with different mechanisms of action.

Spider mites can be killed with 75 alcohol.

After getting the red spider in the month, if there are only one or two pots, and it is maintained at home, and there are children at home, many flower gods are not recommended to use pesticides to kill insects, use cigarette butts to soak in concentrated water, wash clothes, dish soap, alcohol, garlic water and other dilution spray control, so safe and efficient, but if the insect infestation is too serious, the effect of regular use is also not good.

Alcohol kills the moon season red spider precautions.

1. The concentration should be low.

When using alcohol to kill red spiders, you can't spray alcohol directly, so the concentration is too large, and it is easy to burn the leaves, causing the leaves to fall, according to 1500 times the use.

2. It cannot be sprayed back and forth.

There is also a spray can not be sprayed back and forth, once on the line, spray wet on the line, do not spray after spraying and see that there is alcohol and then spray again, once on the line, can not be sprayed several times, the leaves of the moon season are already tender and weak.

3. Ventilation is not exposed to the sun.

When using alcohol spray to prevent red spiders, you can't be exposed to the sun, the environment should be ventilated, you can't spray when you are exposed to high temperatures, spray when it's cool in the evening, and the effect will be good for one night, and then spray water to rinse the next morning, if the rain stops after spraying, you can't spray it immediately, and use it every other day.

4. Don't do too many times.

There is also alcohol spray to prevent and control red spiders, can not be used too many times, so that photosynthesis is seriously hindered, of course, too many times, red spiders will also have a worse effect.

1. Pepper water treatment of red spiders.

This method is relatively common and common, and it is also very easy to learn, convenient and easy to practice, red spiders mostly appear in vegetables, so you can spray it with water to boil peppers. It also works very well. First of all, you need to make homemade chili liquid, and the method of making chili liquid is:

After 50 grams of fresh chili peppers (or dried chili peppers) are mashed, 20 times of water is added, soaked for 5-6 hours, and then filtered and sprayed on the plants, which can effectively control aphids, red spiders, silkworms, etc. However, it should be noted that the amount should be reasonably controlled, not too much, and should be taken slowly, sprayed a few more times to remove the red spider naturally, too hasty is not good for vegetables. After the prevention and control, it is necessary to continue to spray several times to consolidate.

2. Washing and bagging method.

Put the potted plant down directly (be careful not to sprinkle the topsoil), and then hold a water gun in one hand, and gently rub the back of the leaf with your fingers in the other hand. After washing each leaf with water, cover the whole plant with a large garbage bag, and tie it with a rope underneath to moisturize it, because the red spider does not tolerate high humidity environments, so it can quickly kill the red spider. For three days in a row, you can ** red spider.

Because red spiders like to live in a high-temperature, dry, poorly ventilated environment, and red spiders have super reproductive ability, the number is very large, and the damage is serious.

If there is a red spider in the flowers in the family, the easiest and most effective way is to go directly to the flower market to buy pesticides for spraying, such as mite, dimethoate, enemy killing, etc., the effect is good.
