Last Updated: 2024/11/06, When it comes to this kind of plant, do you only think of red varieties? In fact, after crossing, the colors are very varied. For example, white varieties include snowflakes and Christmas white. There are also yellow varieties, such as Jinmei, Golden Fantasy and so on. Then there is pink, such as Camilla, Eva and so on. No matter what variety it is, flowers need leaves to match. So, if white spots grow on the leaves, then it is not very good-looking, then how to deal with it?

1. Insect pests

(1) there is a kind of insect called "shell worm". It is a common pest, their body surface has a waxy layer, the general medicine can not infiltrate. Therefore, it is more harmful, and the leaves may grow white spots after the flowers are eaten by it.

(2) Control methods: first of all, we should adjust the mode according to the number of bugs. If the quantity is small, you can brush them off with a brush or scrape them off with bamboo. It can also be glued off with tape, which is relatively simple and easy to operate. Then, rinse the plant with water.

If there are a lot of bugs, then we have to spray the potion. In general, we can use malathion EC. When spraying, you need to pay attention to evenly spraying the positive and negative sides of the leaves, because the bug may also be found on the back of the leaves.

And then pay attention to the surrounding environmental conditions. At ordinary times, don't forget ventilation, but also give light in time to improve its disease resistance. Also, if one tree is infected, be careful not to let other flowers near it to prevent pests from migrating to other flowers.

2. Disease

(1) reason: it is susceptible to a disease called "powdery mildew". At the beginning of the disease, there will be some small spots on the leaves of the plant. Then, the spots are linked together and appear in the shape of white powder. In general, the lower leaves are more hairy.

(2) Prevention and treatment: first of all, dispose of the diseased leaves. Then we can spray some vermicellin solution. In addition, we need to pay attention to the amount of watering, not too much. In addition, do not splash on the leaves when watering.
