Common Pests and Diseases of Oriental Lilies and Their Control Methods
The Oriental lily is a relatively rare flower species, originally from the Himalayan region of our country. Because its appearance is very beautiful, it is deeply loved by people, but it also has quite a few pests and diseases. So Xiaomian Shuaishuai will tell everyone about 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. Gray mold occurs more often in high-humidity and high-temperature environments, and it can infect multiple parts of the Oriental lily, including its leaves, rhizomes, and flowers. To control this disease, first deal with the parts that have already been affected, and then spray the corresponding medication. You can buy metalaxyl medication. In addition to spraying, we can also disinfect the soil, which can inhibit the growth of fungi.
2. Damping-off
Damping-off is a pathogen that mainly infects the roots of the plant. Once infected with this disease, brown spots will grow on the leaves, and over time it will gradually spread and eventually die. Therefore, 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 it infects 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 also be disinfected. When preventing it, mainly pay attention to the peak period from March to May.
II. Pests
The Oriental lily has very few pests, not as serious as diseases. For Oriental lilies, the main thing is to prevent several kinds, including aphids, white grubs, and cutworms.
