This disease is one of the main diseases and insect pests of jasmine. It is a physiological disease that occurs on leaves. The main feature is that the leaves gradually change from green to yellow, and wrinkles appear, and when the leaves are serious, the leaves fall off, and the plant itself gradually weakens.

The method of prevention and control is to spray leaves or water roots with 0.2-1% black alum water (ferrous sulfate solution). Generally, the concentration of spraying foliar is about 0.2-0.5%. The concentration of watering root can be higher, using 0.5: 1%. Usually after thousands of dew in the morning, spray the plant with black alum water. When the leaf yellow is serious, it can be sprayed once a week.

2. Blight

Blight, one of the diseases and insect pests of jasmine, is also called pinch neck rot. This disease is caused by pathogens invading the root head, softening and festering the stem. When the seedlings survived by cuttings overwintered indoors or in greenhouse, some plants fester at the junction of potted soil and stems and lodge and die.

Prevention and treatment methods: pay attention to ventilation, strong light exposure, appropriate amount of watering, do not dry do not water. When the seedlings entered the greenhouse, the plants were sprayed with 0.2 degree dilute solution of stone sulfur mixture or 700 times solution of topiramine 400 Murray to kill the bacteria. For the plants that have been lodged, buckle the pot, and disinfect the pot soil with 70% pentazonitrobenzene to bury the plant.

3. Safflower disease

In some plants, after the petals open, they soon turn red and rotten. This disease is caused by a fungus. It is mostly caused by uneven watering of feces and disease caused by hot wind. When this disease has occurred, you should immediately stop watering and fertilizing, make the plant dry, see that the leaves are slightly wilted and then water and apply light fertilizer.
