What kind of medicine is effective in the prevention and control of cucumber red spider?

Citrus red spider, also known as citrus full-clawed mites, is the first major pest of citrus, in order to deal with this pest, the annual control cost is almost more than 50% of the cost of citrus pest control. For the prevention and control of red spider (pest mites), we can not simply consider the selection of those drugs, but: one is to use drugs in an appropriate period, the second is to alternate drugs and choose drugs, and the third is to improve the coverage rate of drug fog.

In order to achieve better prevention and control results. 1. Appropriate medication. 1. Liuyangmycin is an agricultural antibiotic acaricide, which can control red spiders in apples, hawthorns and citrus.

Dixazine is a highly active organic nitrogen heterocyclic acaricide, which can control red spiders in apples, hawthorns and citrus.

<> suggests a bactericidal additive, which is still very useful for spider mites. Garlic oil, the concentration of use is generally 1000-1500 times, not only can kill fungal spores, but also has a good effect on bacteria, the use of all know why it is effective for red spiders, moths, the current market agents are mainly in the case of a set, generally speaking, the main components of the current pesticide manufacturers acaricides are avermectin, spirodioxidoxil, ethoxazole, bifenazide, bifenthrin, deltamethrin, probromophos, fluridin, etc.

It has a good contact killing and stomach toxicity effect, and is effective for all characteristics of pest mites, including eggs, nymphs, and adult mites, and has good quick effect, with an effective period of more than 30 days. Because it is an analog of methoxyacrylate fungicides, in addition to being effective against pests and mites, 1. Spray when there are 3 4 red spiders per leaf on average, and do not wait for a large outbreak to spray, which is more difficult to control. Seize the opportunity of spraying pesticides in winter to effectively reduce the base number of overwintering mites and reduce the source of insects in the spring of the next year.

Red spider chemical control application mite danger 4000-5000 times (100 ml per bottle mixed with water 800-1000 pounds) uniform spray, 40% dicofol EC 1000 1500 times liquid, 20% mite kill net wettable powder 2000 times liquid, 15% pyridafen emulsifiable concentrate 2000 times liquid,.

Agricultural control: apply well-decomposed organic fertilizer. In autumn ploughing, some larvae can be turned to the surface and picked up manually or let them be dried, frozen to death or preyed on by natural enemies.

Light trapping to kill adult insects Use 15% pyridoxenone 3 000 times solution, or 73% gmite emulsifiable concentrate 2 000 times solution, or Uranus emulsifiable concentrate 3 000 times liquid spray, spray once every 10 days, spray 3 times in a row.

Liuyangmycin: It has a certain inhibitory effect on eggs, and can also be mixed with organophosphorus pesticides and carbamate pesticides, commonly used 10% emulsifiable concentrate, with a concentration of 1000-1500 times.

The drugs used to control cucumber red spider are: Liuyangmycin, diamidine, Gramite, Damite copper, Nisolan and so on.

5% emamectin benzoate microemulsion 7500-10000 times, 10% bifenthrin EC 3000 times, 20% deltamethrin EC 2000 times, 28% methyl cyanophos 1000 1500 times; Any one or two of the above agents can be mixed with 50% chlorobromoisocyanuric acid soluble powder 1500 times, natural brassinin EC 6000-10000 times, green wind 95600 times, Kebao plant eubiotics 1500-3000 times (transplanted crops, pesticide damage and fertilizer damage, frost damage, waterlogging damage, strong roots and seedlings, and 1500 times used to control the use of wang) to mix evenly foliar spray. 1 time every 5 7 days, 2 3 times of continuous control, focusing on spraying the back of young leaves, young stems, flowers, growth points and young fruits on the upper part of the plant, and pay attention to alternate use.

Nisolan, also known as thiofenone, has good penetration to the plant epidermis, but there is no systemic conduction, the killing effect on young mites is relatively strong, but the effect on adult mites is relatively poor, can inhibit the hatching of some eggs, this drug only needs to be used once a year, otherwise it will produce resistance.

To control spider mite, you can use avermectin, spiroethyl ester, ethoxazole, pyridoxalin, spirofen and other drugs, and then I will tell you about the characteristics of these drugs.

1. Avermectin: It has stomach toxicity and contact killing effect on mites and insects, and cannot kill eggs.

2. Spiral ethyl ester: active against eggs and larvae, with a long duration of effect, and selective for bees.

3. Ethoxazole: It has high activity against eggs and young mites, and is ineffective for adult mites, so it should be used in the early stage of occurrence, when there are not many insects, the effect is very good, and its effective period is long.

4. Pyridoxine: It is effective for all growth periods of leaf mites.

5. Spirodifen: it has contact killing effect and has no systemic properties. It has a good killing effect on the eggs, larvae and of pest mites, and is ineffective against adult mites, but it has the effect of inhibiting the hatching rate of female mites.

Abamectin, ethyl spiroethyl, ethoxazole, pyridoxalin, spirofen and other drugs for the prevention and control of red spiders, the use characteristics of different drugs are different.

When controlling red spiders, you can choose 4000 5000 times of insect mite (avermectin) EC, 1500 2000 times of 5% nisolone (thiofenone) EC, 1000 1500 times of 5% carbogram (fipronitr) EC, 3000 4000 times of 20% tachydinone wettable powder, and 2000 4000 times of 50% Apollo suspension agent, focusing on the prevention and control of middle and lower leaves.

Red spider, the control agents are: avidafen, or metamidine, or spiromel ethyl ester, or tetramitezine, or avirotofen, or avermectin, or zolbifen, or butyl etherurea, or liuyangmycin, or butaflufenofen, or bifenazide, or alkyne mite, etc. The use of alkyne mites is strictly in accordance with the label instructions, and the concentration is too high and easy to be harmed.

Alternate use to prevent resistance.

When controlling red spiders, you can use dicofol, malathion, amitramidine and other drugs, dilute them with water and spray them 1000 times. However, if there are many insect pests and the general drugs cannot be controlled, you can use 10% phenylpyridoxin 1000 times, or mix it with 3000 times emamectin benzoate emulsifiable liquid, so that the effect will be better after spraying. In addition, natural enemies can also be used to eliminate, and the conservation environment should also be changed in time, so that it can be effectively prevented.

It is a pest of mites and is relatively small, usually around 1 mm. If you have just found that there is red spider erosion, you can move to a well-ventilated place, pick the diseased leaves, and wipe the plants frequently with clean water, and the plants will recover after a short time. If the pest infestation is serious, it is necessary to spray pesticides.

The drug can choose dicofol, malathion, amitamidine, etc., and it can be diluted 1000 times and sprayed when used. When there are many insect pests and general drugs cannot be controlled, you can use 10% phenylpyridoxin 1000 times solution or mixed emamectin benzoate emulsifiable concentrate 3000 times, and the effect will be better after mixing.

1. Protection of natural enemies: There are many types and numbers of natural enemies of red spiders, mainly heterochromatic ladybugs, small flower bugs, bundle tube mite ladybugs, deep-spotted mite ladybugs, plant mites, large and small lacewings, etc. They play a positive role in controlling the population of spider mites.

Therefore, it is necessary to protect natural enemies when preventing and controlling.

2. Improve the environment: Spider mites belong to the high-temperature active type, and the high temperature determines its development cycle, the amount of production and the speed of reproduction, which generally occurs in large quantities when the drought is hot. Therefore, if you want to prevent and control it, you must pay attention to the management of the environment, and you must strengthen the prevention and control in the high temperature and dry season.

How to prevent spider mites? What medicine is most effective.

Hello dear, the following are the prevention and control methods and common drugs of red spiders:1Remove weeds and dead leaves, keep the environment around plants clean, and reduce the breeding and reproduction of pests.

2.Spraying water: Spraying plants with a water gun or sprayer can wash off pests and increase the humidity of plants during the noise, which is not conducive to the reproduction of red spiders.

3.Use insecticides: commonly used drugs such as aerobic music, zinc oxide, etc., can be sprayed on the leaves of plants with wide bent pins to effectively kill red spiders.

4.Use of pyrethroids: such as dichloride, beldan, etc.

These drugs have a good control effect on spider mites, but they need to be used correctly according to the instructions. 5.Use of biological control:

Natural predators such as ladybugs, mite bees, etc., can be used to control the reproduction of spider mites. It should be noted that appropriate control measures and drugs should be selected according to the plant species, the species of spider mite, and the severity. When using drugs, use them in accordance with the dosage and method on the instructions, and do not abuse pesticides to avoid harm to the environment and human health.

What is the best way to prevent and control cucumber red spiders? The way to stick the white flour to death is to use one kilogram of white flour, add 30 kilograms of water, add water and stir well, and sprinkle evenly at the bottom of the leaves. Irrigation time is 9:0

00 to 4:00 p.m., about 15 minutes after irrigation. You can see it's like an eggplant.

It is not possible to use other methods without controlling pesticides, but the effect is not very good. Most pesticides are ineffective in the short term. Not using pesticides is a lie, the plantation is too big to see?

It can only be controlled with some medications. However, some pesticides can only kill the eggs, but not the adult mites; Some pesticides can only kill, but not eggs. Therefore, they are mainly used to prevent reuse in the hair room.

1'Spray plant ash. Every morning when there is dew, spray it so that the plant ash adheres to the surface of the plant. 2'With 1:

500x liquid wash samples are not easy to sell. According to some, weeds and fallen leaves on the plot where the eggplant is grown should be cleared without the use of pesticides, which will cause the leaves to gradually fade and decrease, and in order to reduce the pests and diseases caused by eggplant, control efforts should be given top priority. Before planting eggplant, soil medicine should be sprayed on the soil.

After the eggplant survives, the eggplant should be watered and fertilized frequently to make it firm to eliminate overweight eggs.

The soil should be tillage, fertilized and watered so that the soil has enough nutrients to ensure the healthy growth of eggplants. It is effective in preventing bacteria from germinating with more water or dying from spider mites. He was more careful.

Before planting, weeds and fallen leaves in the field, as well as garbage and surrounding weeds, should be carefully removed. In the larval and nymph stages of the mites, he does not like to be active. In the next stage, it rises and its activity increases significantly.

It destroys the lower leaves of the plant and gradually grows upwards. When cleaning, choose to apply decaying agricultural fertilizer or organic fertilizer, then go deep into the soil, breaking up the soil block.

At the same time, when planting eggplant, the grass will spread, and some harmless control measures will be adopted, which can not only ensure the quality and safety of the product, but also greatly reduce the control cost, so as to achieve twice the result with half the effort. Rust spots grow on the surface of the eggplant and become larger and larger. If the condition is severe, it can also cause eggplant to fall and eggplant leaves to fall.

It is arguably the most common parasite in the growth of eggplants. It kills red spiders very well.
