What medicine is most effective for red spiders

<> red spider must be detected and treated early, because the reproduction rate is very fast, and if left unchecked, it will soon be able to torture the entire moon season to death.

The treatment of red spiders should be treated with special acaricidal agents, which can be sprayed with acaricides such as pyridoxin and Aika mite, and it should be sprayed continuously every 5-7 days.

When spraying, the moon season that is not infected with red spider should also be sprayed uniformly for prevention.

For flower friends who don't want to use medicine, it is recommended that you rinse with a pressure water gun, or rinse the leaves directly under the faucet, but this work requires you to persist in doing it for a period of time before it can be completely treated.

Spider mites should still pay attention to prevention, try to keep the environment ventilated, after the spring flowers open, you can remove the old leaves near the bottom of the potting soil, and cut off the blind branches inside, which can enhance the permeability of the plant.

When drying, you can spray the foliage and air more to increase the humidity of the air. What red spiders like is a dry and unventilated environment, try to make the environment unsuitable for red spiders to live, then the incidence of red spiders will be greatly reduced.

When the red spider appears in the moon season, it is best to spray with dicofol EC, if it is not killed at one time, it is easy to appear resistant, it is recommended to use two or three different drugs alternately. When spraying, the back of the blade should also be sprayed.

If you are infected with black spot disease, you can cut off the rotten leaves and spray chlorothalonil. If you are infected with downy mildew, at the beginning of the disease, you need to spray methylmycolin, ethylphosphine and other agents. If it is infected with powdery mildew, it should be sprayed with methyl tobuzin, fenrustin, carbendazim, etc.

In terms of insect pests, there are mainly aphids and red spiders, and if infected with aphids, pymetrozine can be used. If infected with red spiders, dicofol can be sprayed.

In the case of red spiders, dicofol can be used.

It is a red spider, which is very small, and it can't be seen at all if you don't look carefully, most insecticides can be killed, and it is easy to use to protect the flower god.

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.

If there are red spiders on the branches and leaves of the moon, after cutting off the branches and leaves, you can spray dicofol, ethoxazole, metamidine, carcat or dimethoate and other agents for insect control. The agent can be used alternately, between 7 and 10 days, you can spray the moon season once, put the moon season in a ventilated place for maintenance, and the insect pest will gradually disappear after spraying for 3 or 4 days in a row.

The moon season is very susceptible to pests and diseases during the maintenance period, the common insect infestation is the red spider, and during the summer high temperature, the moon season is in a closed, humid and stuffy environment. If you get red spider in the moon, you can use dicofol, ethoxazole, dimetamidine, acer or dimethoate for insect control.

Spider mites attach to the opposite side of the young leaves, sucking the sap of the young leaves, laying eggs and spreading large numbers of germs. Spider mites will dry up and fall off the leaves, and if they are not timed, they will also threaten the young branches of the moon season, and they can wilt and die in the later stage. If there are red spiders on the branches and leaves of the moon, the branches and leaves should be cut off in time and burned in a concentrated manner.

After cutting off the leaves of the insects, dilute the agent with water according to the instructions and spray it on the branches and leaves. During spraying, the front and back of the leaves, branches, potting soil, and inside and outside of the pot need to be sprayed. The agent can be sprayed once between 7 and 10 days, and a variety of agents are used alternately, and after 3 or 4 days of continuous spraying, the spider mites will disappear.

After the insect pest is removed, it is necessary to put the moon season in a cool and ventilated position for maintenance, and during the maintenance period, it is necessary to open the windows frequently to maintain indoor air circulation, which is conducive to the growth of the moon season. During the growth period, in order to avoid being attacked by pests and diseases, it is necessary to water and fertilize reasonably to enhance the disease resistance of the moon season, and to prevent it with appropriate spraying.

The balcony is most likely to be infected by spider mites during the moon season, because the ventilation on the balcony is not good, and the dry and stuffy environment is very suitable for spider mites to breed. In the balcony moon season, we must first do a good job of red spider prevention, autumn and winter dry season, remember to spray water often to increase air humidity, or use a humidifier, regular humidification. In an environment with high air humidity, red spiders do not like it, which can greatly reduce the probability of red spiders.

It is not recommended that you use too many pesticides to deal with red spiders, so use pesticides to treat red spiders, try to do it in one step and avoid repeated medications.

Mix 2 kinds of acaricidal drugs to prepare enough liquid, for example, avermectin and spirodilate can be used together, avermectin mainly kills insects, spirodilate mainly kills eggs, insects and eggs are killed, and the effect of eliminating red spiders will be better.

First spray the foliage, potting soil surface, nearby floor and other flowers and plants with a mixture of these two medicines, and then put the liquid medicine into a large pot or bucket, put the potted plants infected with red spiders into it, and use a water ladle or watering can to repeatedly pour the liquid medicine into the leaves, branches and potting soil of the moon season, to ensure that all the front and back of the leaves, branches, and soil are completely soaked to the solution.

Find an open place, move all the potted plants that you are infected with red spiders, and put them on the ground, and then connect the water pipe to the faucet, turn on the faucet, and it is best to match the pressure nozzle, and if not, pinch the water outlet of the water pipe with your hands, let the water carry the pressure, and rush at the leaves of the moon season, remember: this operation is best operated when the sun is big at noon! At this time, the sun is relatively dry, and the red spiders washed away by the pressurized water are easy to be sunburned, and the probability of crawling back is greatly reduced.

And after flushing, because it is noon, it will create a high temperature and humid environment, which red spiders don't like very much, which can make red spiders who leak the web feel less comfortable and grow and die.
