It is easy to occur in an environment with high temperature, high humidity and poor air circulation. This disease usually occurs in summer.

Fungal Anthracnose Control Methods

When this disease is discovered, first remove all the affected leaves and spray them with medicine. During daily breeding, try to choose a place with good ventilation and plenty of sunlight to reduce the invasion of pathogens.

Occurrence and status of diseases caused by bacteria

The disease occurs three years after the plant is planted, when the plant reaches 20 to 30 cm in height. It mainly attacks the bulbs, which will slowly rot. The reason for the occurrence of diseases is that the soil has not been changed for a long time.

Bacterial disease control methods

When this disease occurs, the plants can only be destroyed and the soil removed together to avoid harming the plants when other plants are planted. To prevent this disease from occurring, you need to change the soil of the plants once every one to two years.

Main pests: spider mites, slugs, etc.

Pest control methods

When discovered, spray it with medicine in time and cut off the leaves that are severely damaged. The peak period for insect pests is from June to September, so good ventilation must be ensured.
