Symptoms of lily of the valley red spot disease

When this disease occurs in Agapanthus, the leaves, pedicels, petals and bulb scales may be affected. After the leaves and pedicels are infected, they become bent or deformed and develop red raised spots; the petals and bulb scales also develop brown spots after being infected, and the diseased parts become soft and sink in the later stage. Severely damaged pedicels will affect flowering. The pathogen is a fungus that can also harm the bulbous flower stems of daffodils, crinums, etc.

Prevention and control methods of red spot disease of Agapanthus

To prevent and control the red spot disease of Agapanthus, prevent water droplets from dripping onto the leaves when watering. The more you spray 600 times diluted Benomyl solution once when the disease occurs, the better the effect will be.

Agapanthus grows slowly, and the time from sowing to flowering is very long, so it will take a long time to be placed indoors or in the corner of the balcony. If the leaves are not beautiful, it will really affect the visual perception.

Therefore, we must take good care of these plants that are placed in front of us all year round to prevent them from getting spots or getting sick. Always provide good ventilation and remember the methods of watering and fertilizing to allow them to grow safely.
