1. Red spiderRed spider mites mainly suck the juice from the leaves, which will destroy the chlorophyll and cause the leaves to turn yellow and dry. When discovered, medical treatment should be provided as soon as possible. You can mix 50 grams of laundry detergent with 500 ml of water, stir well and spray it on the leaves to kill the red spider mites. Or you can spray the medicine directly. You can choose Dichlorvos. After dilution, spray it on both sides of the leaves. It will take effect quickly. 2. Scale InsectsAdult scale insects are easily spotted with the naked eye. After discovering it, you can catch it directly with your hands, or brush it off with a brush dipped in water, and then spray it with a diluted white vinegar solution. This can play a preventive role. However, if the number is large, it is recommended to spray pesticides. You can spray Baichongling and dilute it with water at a ratio of 1:200. 3. AphidsIf it is infected with aphids, but the number is not large, you can also use your hands, a brush or a rag to deal with it directly. If there are a large number of them, you can cover the plants with a larger plastic bag, then light a mosquito coil and put it in. After a while, the bag will be filled with smoke, which will kill the aphids. Or you can spray pesticides, such as dichlorvos, oxydemeton-methyl, or imidacloprid. 4. Mosquito larvaeLucky bamboo grown in water is susceptible to this type of pest. If you want to kill it completely, you should pour out all the water in the container and clean the bottle and roots. After treatment, add water again. Then add vitamin B2 to the water, so that the mosquitoes will dissolve and prevent them from hatching in it. |
