CATDOLL : CATDOLL: How to eliminate red spider mites and what pesticides to use

1. How to eliminate red spider mites and what pesticides to use

Red spider mites can be sprayed with 1000 times of 40% omethoate EC or 4000-5000 times of mite danger (each bottle of 100 ml is diluted with 800-1000 catties of water) and sprayed evenly, 40% trichlorfon EC 1000-1500 times of osmotic fluid, 2000 times of 20% mite-killing wettable powder, 2000 times of 15% pyridaben EC 2000 times of 1. Conggao 8% amitraz EC 6000-8000 times, etc., all of which can achieve ideal control effects. (However, these drugs cannot kill its eggs)

It is best to use it again two weeks after applying the pesticide, so that the red spider mites can be completely eliminated.

2. The concentration of the drug for removing red spider mites from cymbidium is 2000 times, but I used 1000 times. What should I do? ? ?

If the concentration you prepare is too high, you can temporarily put it in a cool place, increase the air humidity, and spray more water. If the red spider has not been completely eliminated after a week, you can spray it again with a normal concentration of liquid!

Of course, if conditions permit, it is best to control the ambient temperature at around 15°C, so that the chance of drug damage will be smaller.

It's not a big problem. Just add some clean water or foliar fertilizer.

3. There are many spiders at home. What medicine can I use to kill them?

Commonly used pesticides include cypermethrin, trichloronate, dimethoate, anthracene, and cypermethrin.

Specific usage and dosage: In 400 ml of water, 4 drops of cypermethrin, cypermethrin or chlorpyrifos can be dropped (equivalent to 2000 times the liquid medicine), and 8 drops of dicofol or dimethoate can be dropped (equivalent to 1000 times the liquid medicine). After adding the medicine, shake the branches and ears evenly, and then spray. The spraying should be uniform and thorough, and special attention should be paid to spraying the back of the leaves.

1. You can use a broom to destroy their webs;

2. You can use low-toxic lime water to spray the ground and corners, and then sweep it away after a few days;

3. If it is in the city, I won’t talk about it. If it is in the rural area, you can tie the straw into a bundle where the plants often appear, lure them to burrow in and roost during the day, and then burn them in batches;

4. You can burn wormwood leaves, mosquito coils, etc. to repel them;

5. You can choose to spray trichlorodicol, which is low toxic to humans and animals
