1. Mosaic: when the disease occurs, there will be uneven dry spots on the leaves, resulting in small leaves, abnormal petals and short plants. When planting, choose virus-free bulbs, strengthen the control of pests, pull out the diseased plants in time and spray insecticides to remove aphids.
2. Leaf blight: the disease mainly occurs on the leaves, producing irregular round spots. In the later stage, the spots will become light yellow or gray brown, which will cause the whole plant to die. At the beginning of the disease, the diseased leaves are removed, and then Bordeaux or bacteriophage is sprayed every 7-10 days.
3. Spot disease: small discolored spots appear on the leaves. There are many small black spots in the center of the spots. In serious cases, the whole leaves turn black and die. Remove the diseased leaves and spray with zineb to prevent the spread of the disease.
4. Bulb rot: this disease will cause disease spots on the bulb, and finally the whole disease spot will rot. At the beginning of the disease, it can be irrigated.
1. Aphid: harmful to the young leaves and stems, sucking the juice inside, resulting in poor growth. Spray with Omethoate and dichlorvos.
2. Ground tiger: it will damage the underground bulb and cause the plant to die. You can use dichlorvos to irrigate the root.
