Flowers dripping Guanyin have pests and diseases, how to treat red spiders?

Red spider is a common disease in the summer high temperature weather of Dripping Guanyin, the insect pest of red spider can make the leaves of Dripping Guanyin turn yellow, so that Dripping Guanyin loses its ornamental value, so its destructive effect is great.

Ways to destroy spider mites:

1) spray pesticides, prevention and control of red spider as a pest, usually should pay attention to observation, when the leaf color is abnormal, should carefully check the back of the leaf, individual leaves are damaged, can remove insect leaves; When more leaves occur, it should be sprayed as soon as possible, and the commonly used pesticides are caricato, dicofol, dimethoate, flower insect net, rapid killing, etc. In 400 ml of water, 4 drops of mitete or rapid kill or flower insect net can be dropped into 4 drops (equivalent to 2000 times the liquid medicine), and 8 drops can be dropped with dicofol or dimethoate (equivalent to 1000 times the liquid medicine), shake well after adding the medicine, and then spray, the spraying requirements are uniform and thoughtful, especially pay attention to spraying the back of the leaves. When spraying, it is best to move potted flowers outdoors, and if spraying indoors, do not approach food and utensils.

After each use, pour out the excess liquid and wash the sprayer with clean water.

2) Spray laundry detergent with water. Laundry detergent is a daily necessities, and the main ingredient is sodium alkylbenzene sulfonate. Laundry detergent has been used for a long time to control crop pests.

Laundry detergent is also widely used in fruit tree pest control. Because laundry detergent has strong adhesion, whether it is used alone, or mixed with chemical pesticides, or used as an additive, it can give full play to its advantages and improve the effect of insect control. However, it can not be used continuously for a long time, because it is easy to produce mold on the branches and leaves of the tree body for a long time, so it is recommended to use it 1 or 2 times a year.

The sodium alkylbenzene sulfonate in laundry detergent enters the body through pest respiration, causing it to die of poisoning. The use of 400 times liquid spraying on the back of leaves, young branches, after 1 2 days, aphids, whiteflies, red spiders, inchworms, stinging moths and other pests mortality can reach 100; Use 500 times liquid spray for scale insects, once every 3 days, spray 3 times in a row, the insecticidal effect can reach 94 99; In the citrus red wax scale and blowing cotton scale nymph stage, the use of laundry detergent 100 150 times liquid, the effect is also very good. After spraying laundry detergent, the head, chest, abdomen, feet, wings, etc. of the insect can quickly remove the wax of the body wall, and a layer of film can be formed to seal the stomata of the insect, so that the pest can suffocate and die.

In addition, pests cannot fly after being stained with laundry detergent solution, and will die after a long time.

At home, try to avoid the use of pesticides, you can use aerosol insecticides, just spray it.

Trouble, thanks!

After the red spider is generated, the infested leaves need to be cut off in time to avoid infecting the normal leaves. It is also necessary to spray special agents in time for prevention and control, so as to completely solve this disease. At the same time, it is also necessary to do a good job of ventilation so that it cannot be allowed to grow in an excessively confined environment.

1. Remove diseased leaves

Red spider is a very common disease, this insect is relatively small, generally found after it, often the plant has been very seriously diseased, so we see that after the dripping Guanyin produces this disease, we need to cut off the damaged leaves in time, so as not to infect the normal leaves.

2. Drug spraying

After the damaged leaves are cut off, we also need to spray special agents in time for control, we can use mite, dicofol, dimethoate, flower insect net and rapid killing and other agents, according to a certain proportion of dilution to spray the leaves of the plant**, so as to completely solve this disease.

3. Ventilation environment

The reason why the dripping Guanyin produces red spiders is likely to be caused by poor ventilation, so we also need to do a good job of ventilation at this time, and it is best to maintain it in places such as window sills, and at the same time to avoid it from being in a hot and humid environment for a long time, so as to prevent it from producing diseases such as red spiders.

If we want to control the red spider on the dripping Guanyin, we need to start from brushing and removing insects, pruning insect leaves, spraying drugs and ventilation prevention. Scrub the spider mites with chili water or garlic water, then cut off the more seriously damaged and infected parts, spray the corresponding drugs, and strengthen ventilation to prevent them from breeding again.

1. Brush and remove insects

First of all, we need to carefully observe the plant, find all the leaves infected with red spiders, and then boil water with garlic or chili peppers, spray chili water or garlic water on the leaves of the plant and then brush the treatment to remove the eggs and pests attached to the leaves, so as to stop the loss in time to avoid the continued damage of red spiders.

2. Prune insect leaves

If the infection of red spider spider is already serious and the damage to the leaves is quite serious, we need to use sterilized sharp scissors to cut off the leaves where red spiders grow, and collect the cut leaves and the leaves that have fallen due to the insect infestation before, and gather them together to burn them to avoid further infection to the plants.

3. Spray drugs

When the red spider is infected with the dripping Guanyin, in addition to brushing and pruning, we also need to prepare the agent to kill the red spider as soon as possible. We can use diluted and sprayed with chemicals such as mite, dicofol, dimethoate and flower insect net, and spray evenly on the whole plant, and spray everywhere.

4. Ventilation prevention

After we sprayed with pesticides, we can temporarily stop the symptoms of red spider infection of the plants, but we still have to move the plants to a sunny, ventilated and breathable place, so that they can breathe more fresh air, only the air is stagnant, the ventilation environment will breed a large number of red spiders.

Dimethoate or dichlorvos spray killing, if you feel that the poisonous gas is larger, you can use the following soil methods. Cigarette head soaking water, laundry detergent soaking water, soap flakes hot water boiling, plant ash soaking water, liquor mixed with water, wind oil essence mixed with water, the above solutions, you can choose any one, you can also cross use, spray chrysanthemums, roses and other flower leaves, repeat for a few days, you can effectively kill aphids. Natural daily necessities are not harmful to the human body, and you can choose to use them.

Methamidophos or thousandth dimethoate.

Let's talk about red spiders first, in fact, this is a type of mites; Arachnidae, Ticks, Leaf Mites.

Therefore, to carry out chemical control, targeted drug selection is required;

In fact, dimethoate itself is good, and it has a certain control effect on mites, but it is not a special acaricide; Dimethoate can't kill the eggs of red spiders, red spiders are very fecundive, and they are good at hiding, killing the adults, and the eggs will hatch immediately, so dimethoate is not the first choice;

Mites, dicofol EC, mite-dead wettable powder, 1 8 zitogenol EC can all achieve a relatively ideal effect;

In addition, when spraying, be sure to focus on spraying the back of the leaf, red spider especially likes to hide on the back of the leaf.

There is also prevention is better than cure, when there is no red spider, it is necessary to spray in advance to prevent and control, the better is avermectin, a spray can be used for 2 months without worms, why not use avermectin to kill red spiders? Because avermectin can't kill the eggs of red spiders like dimethoate, but it has a long residual effect, and it is best to prevent adult worms.

Don't deal with it, she's going to die herself.

If the baby's method is not feasible, I suggest that you use sulfuric acid powder (the effect is quite good) Usage: first remove the cobwebs with something and then gently spray a layer of mist with a watering can Then find a bucket-shaped object (toilet paper bucket) Put the sulfuric acid powder in it a little and blow it on the other end of the disease (blow all over the disease in turn) Three days later, the medicine will be removed Wash the entire dripping Guanyin with water Change the soil and change the pot to clean and disinfect the basin (you can soak 500 times potassium permanganate for 30 minutes) potassium permanganate is sold in ordinary pharmacies After the cool dry plant pot, pot it with new soil for a week, and the normal management is OK! Thank you!

Is it a red spider? If there is less to cut off the leaves, if more can be sprayed with dimethoate 1000 times, and at the same time isolate from other flowers, so as not to infect them.

This is not a spider, it is a kind of mite that is harming the dripping Guanyin.

They are small, web-forming, crawl quickly, and live by sucking sap, causing the leaves to curl and wilt and fall off. When the weather is sunny and hot, it reproduces faster and is more harmful (if the damage is not serious, the leaves will not fall off).

In terms of control, you can put the flower pot under the tap and flush it with water, while scraping off the insects with bamboo pieces or brushes. It can also be diluted 400-800 times with neutral laundry detergent and sprayed. If there are a lot of insects, you can buy some miteicidal pesticides and use them according to the requirements on the instructions.

Correct my post above Not sulfuric acid powder! It's with sulfur powder! [em10]

I haven't been here for a long time, and I just saw the detailed explanation of Humility, thank you very much[em10].

Here are some of the safer methods offered by netizens.

1 Soak in water with tobacco for about two or three days, then spray red spiders;

2. Spray with onion water. Buy two onions (larger), cut them into small pieces, add water to the juicer to make a pulp, and finally add water to 800 ml, overnight, filter out the residue with gauze, and spray the filtrate with a watering can to spray the front and back of the leaves. Spray again in three days.

3. Garlic and onion are planted together or separately near the plant;

5. Put 30 grams of garlic or citrus peel into a blender and add some water to break it, filter out the juice and add 2 kg of water, spray it on both sides of the leaves, and after the water is dry, you can see that most of the red spiders are hanging.

Pesticide control can also be fast, with avermectin, which is a metabolite of bacteria and is harmless to humans.

My dripping Guanyin also had red spiders, and it was not cured at the time, but after a period of time, he got better, and this kind of insect occurs seasonally.

Coat all the leaves with noodle soup and make sure **! Eco-friendly and good! Don't be too thick!

If you can gently crush it with your hands, then I will kill it like that, after all, there are not too many leaves, and it is suggested that you can move the dripping Guanyin to a more humid place, and the red spider seems to be easier to appear in dry places.

1.There are generally two kinds of disease reactions on the leaves, one is leaf spot disease, and the other is anthrax. Leaf spot can be sprayed with chlorothalonil or carbendazim 800 times liquid foliar spray, 2-3 times in a row, each time every 7 days.

Anthrax must be sprayed with 75% methyl tobuzine 500 times liquid foliar spray, once every 7 days, 2-3 times in a row, which can be basically controlled. Because it is a foliage plant, once the leaves are sick, it will inevitably affect its ornamental effect, so prevention should be the mainstay.

2.Reaction on the stem, there is a kind of blight, which is caused by bacterial infection, which is not easy to be detected at the beginning, and once it is found, it will be very serious. If you find that the stem is crooked to one side, or there is a wilting place, it must be a withered and wilted disease, you can use a knife to cut off the disease, the boundary between the diseased place and the non-diseased place is very obvious, and you can generally break it off by hand.

If the diseased area is less than one-third of the stem, you can apply a layer of chlorothalonil liquid to the undiseased area, keep it dry, apply it again every 10 days, and basically heal after 20 days.

3.The most serious insect infestation is mites, commonly known as red spiders. Spider mites are usually born on the dorsal backs of leaves, where they not only feed on the nutrients of the leaves, but also transmit various viruses.

It greatly affects the growth of plants, so be sure to check it often, and if you find it, immediately**. It can be carried out with mite removal, mite sweeping, imidacloprid and other drugs**.
