What are the common pests and diseases of lilies? Detailed explanation of prevention and control measures

The lily is a flower variety with a very beautiful meaning. As you can tell from its name, it is a beautiful flower, and the lily's flower color is pure white, very pure. Many people like to grow it as a potted plant at home. During the cultivation process, some beginners may encounter other problems and pests and diseases due to poor care. So below, Shuaishuai will introduce to everyone what pests and diseases lilies have and the prevention and control measures!

1. Blue mold

Blue mold is a bacterial disease. The pathogen attacks lily leaves. Once infected, it causes some white spots to grow on the leaves. These spots slowly enlarge and develop into patches. Finally, the pathogen invades the basal plate of the bulb. Once the basal plate is gone, the bulb loses its own value, causing the plant to grow slowly, and the pathogen can also infect one another. We should store the seeds at the lowest temperature. Infected ones must be soaked for more than half an hour in an aqueous solution of fungicides such as captan, chlorothalonil, and carbendazim. After soaking, they can be planted.

2. Rhizoctonia

This pathogen mainly infects only the leaves in the soil. Light brown spots appear on the leaves. If mild, it will only have a slight effect, but if the infection is severe, it will affect growth, and then the underground part of the leaves will rot and finally wilt. At this time, we should use a soil disinfectant to disinfect the already infected soil. For the disinfected soil, we must ensure it cannot be infected again, otherwise it is as if it was not disinfected at all.

3. Phytophthora

Phytophthora is a pathogen that can make the plant suddenly wilt. It causes the plant to rot, and the stem also develops soft rot. After rotting, it turns dark brown and then spreads outward. We can use a soil disinfectant to disinfect the soil first, and then use a fungicide to control foot rot. The soil must have good drainage. In addition, we must prevent the crop from remaining in a moist state after watering. In summer, the soil temperature should be kept at the lowest to prevent high temperatures from breeding pathogens.

4. Pythium Pythium is a broad-spectrum pathogen. It can infect a single plant and can also infect all plants within a range. Diseased plants have their development inhibited, resulting in stunted plants, yellowing leaves, and shriveled flower buds. If the plant is pulled out, obvious light brown rot spots can be seen on the root and stem area. They may have already become completely soft and rotted. We should spray the soil with a soil disinfectant to disinfect it, and also spray the crop with a fungicide to prevent Pythium disease. Before spraying the fungicide, spray a little water first, as this makes the insecticidal effect better. It is best to do this in the evening.
