1. Which medicine is most effective?It is a kind of pest belonging to the mite family, and its body size is relatively small, usually around 1 mm. If you have just discovered that the plant has been infested by red spider mites, move it to a well-ventilated place, pick off the diseased leaves, and wipe the plant frequently with clean water. The plant will recover soon. If the pest is serious, you still need to spray pesticides. The drugs you can choose include trichloronate, malathion, amitraz, etc. Just dilute them 1000 times and spray them. When there are too many insect pests to be controlled by ordinary drugs, you can use 1000 times diluted 10% benbuterol or mix it with 3000 times diluted 5.7% emamectin benzoate emulsifiable concentrate. The effect will be better after mixing. 2. How to prevent and treat1. Protect natural enemies: There are many types and numbers of natural enemies of red spiders, mainly including Harmonia axyridis, Small flower stink bug, Tube-tube mite-feeding ladybird, Deep-spotted mite-feeding ladybird, Phytoseiid mites, large and small lacewings, etc. They can play a positive role in controlling the number of red spider mites. Therefore, we must protect natural enemies during prevention and control. 2. Improve the environment: Red spider mites are active in high temperatures. High temperatures determine their development cycle, production and reproduction rate. They usually occur in large numbers during droughts and heat waves. Therefore, if you want to prevent and control it, you must pay attention to environmental management, and you must strengthen prevention and control during high temperature and dry seasons. |
