A Detailed Guide to Common Pests and Diseases of Oriental Lilies and Their Control Methods
The Oriental lily is a relatively rare flower species. It originated in the Himalayan region of China, and because of its beautiful appearance, it is deeply loved by people. However, it also has quite a few pests and diseases. So now Shuashuai will tell everyone what pests and diseases Oriental lilies have and how to control them!
I. Diseases
1. Gray mold
Gray mold is a disease caused by fungi. It occurs more frequently in high-humidity, high-temperature environments, and it can infect multiple parts of the Oriental lily, damaging its leaves, stems and roots, and flowers. To control this disease, you must first deal with the parts that have already been affected, and then spray the corresponding medication. You can buy metalaxyl. In addition to spraying, we can also disinfect the soil, which can inhibit the growth of the fungus.
2. Damping-off
Damping-off is a pathogen that mainly infects the roots of the plant. Once infected, this disease causes brown spots to grow on the leaves, and over time it will gradually spread, and eventually the plant dies. So after infection with this disease, the soil should be disinfected, and then chlorothalonil should be sprayed to eliminate the pathogen.
3. Root rot
As the name suggests, this disease is also a pathogen that harms the roots. After infecting the plant, it first causes the plant to rot, then prevents the plant from absorbing water, and finally causes death. For this disease, metalaxyl should be sprayed, and the soil should be disinfected at the same time. When preventing it, mainly pay attention to the peak period from March to May.
II. Pests
Oriental lilies have few pests, and they are not as serious as diseases. For Oriental lilies, the main thing is to prevent aphids, white grubs, and cutworms. They often appear together in large numbers, and their harm to Oriental lilies is also relatively great. Insecticides can be used for control, such as spraying omethoate.
