Common Pests and Diseases of Lilies and the Latest Control Measures
The lily is a flower with a very beautiful meaning, and you can tell from its name that it is a beautiful flower. Moreover, the lily's flower color is pure white, very pure, and many people like to grow it as a potted plant at home. During the cultivation process, some beginners may, due to poor care, run into some other problems and pests and diseases. So below, Shuaishuai will introduce to you what pests and diseases lilies have and the control measures!
1. Blue mold
Blue mold is a bacterial disease. The pathogen attacks the leaves of lilies. Once infected, the leaves develop some white spots, and these spots will slowly grow larger and develop into blotches. 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 in an aqueous solution of fungicides such as captan, chlorothalonil, and carbendazim for more than half an hour. After soaking, they can be planted.
2. Rhizoctonia
This pathogen mainly infects only the leaves in the soil, and the leaves will show light brown spots. If it is mild, it will only have a slight effect, but if the infection is very 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 that it cannot be infected again, otherwise it is the same as not having disinfected it.
3. Phytophthora
Phytophthora is a pathogen that can make a plant suddenly wilt. It will cause the plant to rot, and the stem will also develop soft rot. After rotting, it will turn dark brown and then spread outward. We can use a soil disinfectant to disinfect the soil first, and then use a fungicide to control foot rot. The soil's drainage must be good. In addition, we must prevent the crop from remaining in a wet 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-range pathogen. It can attack a single plant and can also attack all plants within a range. Diseased plants will 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 at the root and stem area, and they may have completely softened 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 rot. 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.
