CATDOLL : CATDOLL: Complete list of drugs for killing red spider mites and killing eggs (ranking of special drugs for killing red spider mites)

1. Top ten ovicidal insecticides?

1. Avermectin + triazophos: It has better control effect on cotton bollworm. It is recommended to apply the pesticide twice during the cotton bud and boll stage, from the peak hatching period of cotton bollworm eggs to the early larval stage, and evenly spray the leaves with water according to the prescribed amount.

2. Promethazine + Bromocyclopyralid: Mainly used to control red spider mites in citrus trees. It is applied in the early stage of red spider mites and has a killing effect on eggs, nymphs and adult mites. However, it is more sensitive to the tender branches and leaves of citrus spring shoots, so when applying the pesticide, avoid the liquid drifting to the above crops.

3. High-efficiency chlorfenapyr + lufenuron: It can be used to control pests such as cabbage beet armyworm, Spodoptera litura, Plutella xylostella, and cabbage looper. The drug can be used from the peak egg hatching period to the early larval stage. It has a fast insecticidal speed and a long lasting effect, and has a good control effect on both eggs and larvae.

4. Spirodiclofen + Fenbutatin: It has good control effect on citrus red spider mites and is active against mite eggs, larvae, nymphs and adult mites. It can also be used to control harmful mites that are resistant to existing acaricides.

5. Fluflumuron + highly effective cypermethrin: Mainly used to control pests such as diamondback moth and cabbage looper. It can be used during the peak period of pest egg hatching to the peak period of 1-2 instar larvae. It can not only inhibit the conduction of pest nerve impulses, but also inhibit the synthesis of chitin during embryonic development in the eggs, making the eggs unable to hatch normally.

2. Medicine to kill red spider mites?

Red spider mites are a type of mite, scientifically known as Tetranychus cinnabarinus. The most effective drugs to kill red spider mites are: Acarid, Jinmanzhi, Ceramide, and Damanlin.

1. Love card mites?

IkaMite is a new generation of acaricide. Its active ingredient, bifenazate, interferes with the nervous system of harmful mites, causing them to quickly paralyze, stop feeding and eventually die. Unlike other acaricides, it has a reliable preventive and therapeutic effect on mites that have developed resistance to other acaricides. It is effective at all life stages of mites and is particularly effective against spider mites.

2. A branch full of gold?

Jinmanzhi is a new type of benzoylacetonitrile acaricide, which has no cross-resistance with existing insecticides. It is used to control the main mites parasitic on plants in crops such as fruit trees, vegetables, tea trees, and flowers. It is effective against both eggs and adult spider mites, and is more active against nymph mites. The mites die quickly after application. According to experimental comparisons, cyfluthrin is superior to spirocyclobutanil and avermectin in all aspects. The original drug is a milky white solid with no odor.

3. Cetirizine?

Prochlorazine can be used to control harmful mites on various crops such as cotton, vegetables, apples, citrus, tea, and flowers. This product has low toxicity. When harmful mites come into contact with an effective dose of the agent, they immediately stop eating and reduce egg-laying, and die within 48-96 hours. Crops can be protected in time. Prochlorazine has a wide range of effects and can kill many types of harmful mites. It can also kill harmful mites that have developed resistance to other insecticides. It has good effects on killing adult mites, nymphs, and young mites.

4. Damanlin?

Damanlin can be used to control a variety of plant-eating pest mites. It has a good effect on the entire growth period of mites, namely eggs, young mites, nymphs and adult mites. It also has a significant quick-killing effect on adult mites in the mobile period. The drug is not affected by temperature changes. Whether used in early spring or autumn, it can achieve satisfactory results. It is a high-efficiency, broad-spectrum miticide with no systemicity. It has a significant control effect on plant-eating pest mites such as spider mites, panonychus mites, small-clawed mites and gall mites. In general, use 5000 times of 5% avermectin + 3000 times of 24% spirodiclofen suspension. However, this is just a suggestion. The specific medication can be adjusted according to the situation. Never use a single medication! The agent should be selected according to the occurrence law of different stages of red spider mites and the resistance level of red spider mites in each nursery. Diflubenzuron is the most effective for killing red spider mites.

3. What pesticide can be used to kill red spider mites?

Use acaricide for red spider mites.

To control red spider mites, the commonly used miticides are:

15% pyridabenzan EC has no systemic effect, but has stomach poison and contact killing effects. Carefully spraying crops can effectively kill the four life forms of red spider mites: eggs, larvae, nymphs, and adult mites. Nowadays, pyridabenzan is generally used in combination, such as mixing with spirocyclopentane, etoxazole, avermectin, etc., which has a better mite killing effect.

4. Which of the following drugs, avermectin, thiamethoxam and cypermethrin, is more effective against red spider mites?

Which of the following drugs, avermectin, thiamethoxam and cypermethrin, is more effective against red spider mites? My answer is a riddle: two are effective and one is not. Let's take a look at these three drugs first.

1. Pyridaben

This is an old drug. Judging from the name alone, it is effective against mites. It is indeed effective in beating down mites. It is a broad-spectrum contact acaricide with no systemic properties. It is effective against all growth stages of mites, that is, it has a preventive and control effect on mite eggs, larvae, nymphs, and adult mites.

Damanlin has a strong killing ability and is not affected by temperature. It can be used during the mite breeding season and has good adaptability, but it cannot be mixed with alkaline pesticides.

Common forms of pyraclostrobin include 20% wettable powder and 15% emulsifiable concentrate. To avoid the development of drug resistance in mites, it is best to use it alternately or mix it with other miticides.

2. Avermectin

Avermectin, also known as avermectin, is a neurotoxin acaricide that is not systemic but has strong permeability and can kill through the skin. It is only effective against young and adult mites, and has no lethality to mite eggs and does not kill the eggs.

Abamectin has a relatively long lasting effect, but its efficacy is slow. Generally, after application, the pest's nervous system is paralyzed, thus losing the ability to eat and drink, and the peak of mortality is reached after 2-4 days. Abamectin is also effective against caterpillars and the golden moth, leafminer, and leafminer that penetrate into the leaf tissue. It also has a good control effect on underground pests such as root nematodes and beetle larvae.

3. Thiamethoxam

Thiamethoxam is a second-generation nicotinoid insecticide with high efficiency and low toxicity. It has both contact and systemic activity as a stomach poison and can be used for leaf spraying, seed treatment, and soil treatment.

After application, thiamethoxam can be quickly absorbed by crops and transmitted to various parts of the plant, and has a unique control effect on piercing-sucking pests such as aphids, planthoppers, leafhoppers, whiteflies, and scale insects.

The insecticidal mechanism of thiamethoxam is basically similar to that of the first-generation nicotinoid insecticides, such as imidacloprid, which mainly inhibits the central nervous system of piercing-sucking pests, causing them to die due to limb paralysis and inability to suck sap.

Thiamethoxam cannot be mixed with alkaline drugs, but can be mixed with other insecticides and fungicides.

From the above introduction, it can be seen that the two drugs that are effective against mites are cypermethrin and avermectin, while the ineffective one should be thiamethoxam.

In short, mites are pests that tend to move towards tender plants, mainly harming tender flowers, leaves, branches, and fruits of crops, and they hide and harm under their backs. Therefore, when spraying miticides, you should spray both sides, and be careful and thoughtful. Mites have strong reproductive capacity and can reproduce without looking for a husband. The best time to use the drug should be during the peak hatching period of eggs. Because mites are eggs, young mites, and adult mites mixed together, you can mix dacarbamectin and abamectin together to form a dacarbamectin miticide for spraying. It is much more effective than a single agent and delays the drug resistance of mites.
