1. What happened?Its maintenance can be divided into water maintenance and soil maintenance. If a plant grown in water is infested with insects, it is usually due to water quality problems. If the water is not changed for a long time, it will become contaminated and easily breed insects. The plants will also be damaged, affecting their growth. If the plants are grown in soil and get infested with insects, it is mostly caused by poor ventilation or a humid environment. If you keep it in a place with poor air circulation for a long time and the soil is damp, such an environment will make it easy for it to be infected by pests, so you must treat it in time when you find it. 2. What to do1. Improve the environment: No matter what maintenance method is used, the maintenance environment must be changed as soon as possible after insects appear. If grown in water, the water needs to be changed. Be sure to cut off the rotten roots at the bottom, disinfect the plant and container, and then put it back in water for maintenance. Plants grown in soil should be moved to a ventilated place and allowed to blow more air to evaporate the moisture. In serious cases, you need to remove the plant from the pot and change the soil. 2. Eliminate pests: If the number of pests is relatively small, you can directly use your hands, a rag or a brush to deal with the pests. Later, provide an environment conducive to growth, and they will slowly recover. 3. Spraying medicine: If there are a lot of pests, it is recommended to spray medicine to treat them, so that they can be completely cured. The drugs you can choose include dichlorvos, trichlorfon, etc. Pay attention to the dilution concentration. The concentration should not be too high, otherwise it will easily cause phytotoxicity. |
