How to prevent and control leaf spot disease when growing edible lilies? Please explain the control methods
Lily leaf spot mainly affects the stems and leaves of lilies. After the leaves are infected, round lesions appear, slightly sunken. As a large number of conidia emerge, they turn dark brown or black, and in severe cases the leaves wither and turn yellow. If the lesions occur on the stem, the stem becomes thinner and in severe cases rots and the plant dies. The following methods can be used for integrated control:
1. Select disease-free bulbs for planting.
2. Keep the field well ventilated and exposed to light.
3. Practice crop rotation, drain promptly after rain, and reduce soil surface moisture.
4. Disinfect the soil and bulbs before sowing.
5. Before and after the disease occurs, spray Bordeaux mixture at 1:1:100 or 65% zineb wettable powder at 500 times dilution, once every 7 days, for 3 to 4 consecutive sprays, to control the disease. The above measures can also simultaneously control lily bulb rot.
