Speaking of red spiders, farmers’ friends are certainly no strangers. This kind of worm is also called mite. Don’t look small, but the harm is not small. It can occur on many crops, especially citrus, cotton, apple, flowers, vegetables The harm is serious. Prevention is always incomplete, and the effect of medication is not obvious.

First introduce a drug, its name is ethizole, this drug is effective for eggs and young mites, not effective for adult mites, but it has a good infertility effect on female adult mites. Therefore, the best time for prevention and control is the initial period of harm by pests. Strong rain resistance, the duration is up to 50 days. Another drug is spirotetramat. Both are effective against eggs and young nymphs, but they are not effective against adult mites. The duration of effect is more than 30 days. It is a long-acting acaricide that has emerged in the past two years. It is stable and effective at low temperatures. Both acaricides and avermectin or adjuvants have a certain synergistic effect. And the use effect is better in the early stage of mite infestation. For example, some cotton farmers use acetaconazole or spirotetramat once in May-June this year, and the mite damage is at a lower level throughout the year.

In the early stage of the danger of spider mite, spray with dimethoxazole diluted 3000-4000 times with water. Can effectively control the entire juvenile period of mites (eggs, juvenile mites and nymphs). The duration is up to 40-50 days. The effect of compounding with avermectin is more prominent. For the occurrence of cotton spider mites in the middle and late stages of cotton, it is recommended to use acetazol or spirotetramat in combination with avermectin. It mainly controls red spiders of apples and citrus. It also has excellent control effects on spider mites, spider mites, total claw mites, two-spotted spider mites, spider mites and other mites such as cotton, flowers and vegetables.

etoxazole is a non-temperature-sensitive, selective acaricidal, selective acaricide. There is no systemic, spray the whole plant when spraying, for cotton leaves, it is better to spray the back of the leaves. It is safe, efficient, and long lasting. It can effectively control the harmful acarids produced by existing acaricides, and has good resistance to rain erosion. If it does not encounter heavy rain 2 hours after the application, no additional spray is required.
