What kind of medicine should be used for scale insects on trees?

Succulents grow scale insects, what medicine is most effective to kill insects, see what medicine I use to kill insects.

The specific drugs of scale insects are: phosphorus, thiamethoxam, and organosilicon penetrants.

1. Phosphorus:

Phosphine is a commonly used drug for insecticide, which is not only safe, but also very effective, and can remove many common insects. However, there are also disadvantages, the disadvantage is that the taste is a bit big and it will be pungent. If you want to use it indoors, you still need to pay more attention.

2. Thiaproxam:

This drug has little toxicity, will not affect human health, and also has a good insecticidal effect, can be mixed with other agents to kill insects, the effect will be better after mixing.

3. Silicone penetrant:

The agent has a longer-lasting effect and penetrates into the pores of the plant. It can be used as an adjunct to the above two drugs, and can completely penetrate the eggs, so as to kill the eggs. In addition to spraying, you can also use medicine to irrigate the roots, which is also very effective.

In addition, the maintenance environment should be changed after spraying to avoid re-infection.

How to completely eradicate scale insects?

If the number of scale insects is not large, you can pinch it off directly by hand or clip it off with tweezers when you find it. If there is a lot of infestation, the part that is infected with the insect should be cut off and completely destroyed. If there is one in the soil, it is recommended to change the soil directly.

However, if the insect infestation is more serious, the best way is to spray the treatment. Spraying with the above three drugs in turn, the effect is relatively fast. In addition, it is necessary to change the maintenance environment in the later stage and ventilate the plants more.

There are scale insects in the golden branches and jade leaves, and one kind of "medicine" is used, and it is "done" after spraying

Pyryl ether, spiromel ethyl ester, chlorpyrifos1. Pyripropyl ether is a relatively good agent for the prevention and control of scale insects, and its effective period can be as long as more than 2 months. Moreover, the success is not high, and there is no cost burden. It can not only control scale insects, but also thrips, aphids, psyllids, etc., the effect is very outstanding.

2. Snail ethyl ester has strong systemic properties, can be transmitted in both directions in the plant, and the insecticidal speed is relatively slow, and it takes about 10-15 days to completely kill the insects like pyridyl ether!

3. The toxicity of chlorpyrifos is greater than that of the first two, and it mainly kills scale insects through contact killing and stomach poisoning, and there is no systemic property. The insecticidal effect is relatively good. However, it must have been used for a long time, and the insects are more resistant to it, and the toxicity is relatively large, and it has come to the verge of being restricted.

When eliminating scale insects, you can use chlorpyrophosphine, this drug is very safe, and it also has a good effect, but the smell is not good, if it is a plant that is maintained indoors, it is best not to use it. You can also use thiamethoxam, which is very healthy and will not harm human health, and the effect will be better if it can be mixed with other drugs. In addition, silicone penetrants can also be used, which can be used not only for spraying, but also for irrigating roots, and the effect is also very good.

In addition, the maintenance environment should be changed after spraying to avoid re-infection.

You can use plant-specific insecticides, evenly spray on the leaves of plants, and should not be watered during the medication, otherwise there is no effect, you can spray several more times to consolidate the effect.

The drug used to kill scale insects can be phosphorus, which is an ideal drug, but its disadvantage is that the smell is relatively large, and silicone penetrants can also be used, which has the advantage of being more durable and resistant to rain.

If you like to raise flowers, remember to prepare several insecticides, the effect is very good.

The most effective ways to kill scale insects are the use of fungicides, alcohol, soap, garlic water, etc.

1. Use fungicides.

Spraying pesticides during plant growth can effectively prevent scale insects from crawling onto plant leaves. Just put it in a cool and ventilated place.

2. Use alcohol to eliminate scale insects.

Scale insects have a weak tolerance to alcohol, which can kill many scale insects to a large extent, and the smell is relatively less unpleasant. Applying alcohol may miss corners such as roots, so you can use spraying. However, there are some drawbacks to using alcohol, it may damage the leaves, and dripping into the soil and being absorbed by the roots may also be detrimental to plant growth.

3. Use soap to eliminate scale insects.

Liquid soap can also be used to get rid of scale insects. Take a small piece of soap, add hot water to speed up the dissolution, put it aside to cool, wait for the soap block to dissolve, touch the liquid with your hand has become cool, and then put it into the spray bottle, shake it up and down vigorously until the foam appears, it means that the fusion is complete. After spraying, it can quickly eliminate scale insects, which is very effective.

4. Garlic water to remove scale insects.

Garlic is very effective for dealing with scale insects. Mash the garlic and soak it in water until it blends with the garlic juice to strain out the crushed garlic. The liquid is ready to use in a spraying can, sprayed on the leaf where the scale insects are located, and sprayed every few days, which will eliminate these annoying insects and prevent other diseases after a few days.

Specific prevention and control methods:

1. In the early stage of hatching of scale insects, before the waxy scale shell is formed, dilute it with 40% dimethoate emulsion with water 1200 times, spray on the front and back of camellia branches and leaves, spray once every 7 10 days, 2 3 times in a row, and spray evenly to be even. If the shell has already formed, it is difficult to spray it.

2. The shell has been formed, which can be brushed off with a soft brush, pinched to death with fingers, or combined with pruning, cut off insect branches and leaves, and burned intensively.

3. It can be prevented and controlled by liquor and vinegar. Mix about 60 degrees of liquor with 2 times water. Soak a cotton ball in white wine and vinegar and apply it to the scale insects on the leaves and branches.

The most effective drugs to kill scale insects are: profen, pyripropyl ether, spiromel ethyl ester, chlorpyrifos, thiazinone, etc.

1. Phosphorus:

Phosphorus sieve is a highly effective organophosphorus insecticide with good permeability and thorough insecticide. It is the best agent for the control of scale insects. However, because of the high toxicity of chlorphosphine and the potential safety hazards, it was banned by the relevant departments in the past few years.

2. Pyridyl ether

Pyripropyl ether has high activity against scale insects, is used scientifically, and has an effective period of more than two months. The most important thing is that propylene ether is an inhibitor of chitin synthesis in insects, which can not only treat scale insects, but also effectively kill the eggs of thrips, aphids, psyllids and other pests.

3. Spiral ethyl ester

Spirofen ethyl ester is another special effect ingredient of **scale scale insects, but the cost is high, it prevents scale insects mainly because of its super systemic insecticidal effect, which can be transmitted in both directions in the plant, and also belongs to the category of slow insecticidal speed, 10-15 days to completely kill insects!

When using spirometallethyl ester, it is generally recommended to use 1500-2000 times of spirolexethyl ester suspension, in order to improve the quick effect, it is recommended to use acetamiprid, cis-cypermethrin and other ingredients!

4. Chlorpyrifos

Chlorpyrifos is used in a large amount in the scale insect market, and it is a common organophosphorus insecticide, mainly for contact killing and stomach toxicity. But over the years, due to heavy use, the effectiveness of chlorpyrifos has decreased year by year! For chlorpyrifos control of scale insects, it is recommended to use 50% chlorpyrifos 2000-3000 times spray, for high-resistance areas, it is recommended not to use alone, with pyridyl ether, spiroethyl ester, the effect is better!

5. Thiazinone

The direction of thiazinone product registration also has scale insects, with thiazinone alone, it is generally recommended to spray 1000-1500 times of 40% thiazinone suspension, and it is recommended to use other agents in high-resistance areas, such as acetamiprid, chlorpyrifos, cypermethrin, etc.!

Phosphorus can be used to kill scale insects, which is an ideal agent for killing scale insects, which can also treat mites, whiteflies, and aphids, and has a special effect on pear psyllids.

In 1950, the American Cyanamide Company synthesized an organophosphorus insecticide with low toxicity to mammals - malathion; In 1952, W. Perkow discovered the reaction of synthetic vinyl phosphate, and synthesized dichlorvos and phosphorus with excellent insecticidal activity, which brought the development of organophosphorus insecticides to a new stage.

Scale insects....Female adults and nymphs suck nutrients on the branches, and occasionally on the fruits and leaves. In severe cases, the shells are densely overlapped, forming branch surfaces and unevenness, weakening the tree, and destroying the whole orchard in 3 to 5 years. It can be controlled with cyfluthrin, matrine, halodioxapyr, pyridafen, etc.

1. Phosphorus: This is a more commonly used drug for insecticide, which is relatively safe and can also have a good effect, which can remove a series of insects, the disadvantage is that the taste is a bit big, and the smell is more pungent, if you use it at home, you can pay attention to this.

2. Thiamethoxam: its toxicity is relatively small, has no effect on the human body, can play a highly effective insecticidal effect, and can be combined with other agents to kill insects, so that the effect will be better.

3. Silicone penetrant: it can have tension, penetrate into the pores of plants, the effect is very long-lasting, and it will not have an impact when it comes to rain, and the other two agents can completely penetrate the eggs and kill the eggs. In addition to spraying the leaves, spray the surface of the potting soil and irrigate the roots with clean water.

Organophosphorus pesticides. In early spring it can be prevented with a stone sulfur mixture, now it will be easy.
