1、 What is white

White things appear on the leaves of raised flowers. You can take a look. If there are no insects inside, it may be infected with powdery mildew. This is caused by bacterial infection. There are many incentives for this situation. If the application of water and fertilizer is incorrect and the light is not well controlled, it will cause this disease. At first, it is just irregular small spots, which will gradually expand later

If you look out and see that there are small insects in it, it is infected with insects, that is, beetles. They absorb the juice in the leaves and will cause fallen leaves over a long time

2、 How to remove

1. If powdery mildew, you can spray carbendazim or other antibacterial drugs, cooperate with timely ventilation and contact with the sun, and it will be cured after a period of time. This disease is easy to appear at the turn of seasons, so you can pay more attention at that time

2. If there are pests, you can spray some drugs to treat insect diseases, such as chlorpyrifos and imidacloprid, and spray them with water. You can also use a brush dipped in salt water or soapy water to brush down from the bottom of the blade. Pay attention to brush more times to prevent leakage. Then put it in a ventilated place
