Wolfberry anthracnose is also called black fruit disease. When the fruit is blue, there will be small black spots or brown spots on the surface of the fruit. If it is cloudy and rainy, the spots will become larger, causing the whole fruit to become black.
This kind of disease often occurs in the rainy season, but in the dry season, the disease is mild and spreads slowly.

Qingyuan. In early spring or late autumn, clean up the stumps and diseased branches of the wolfberry garden, and then burn them intensively.
Select planting varieties. As far as possible, select varieties with strong disease resistance.
Rational farming. The purpose is to remove the grass roots, bacteria and insect pests that overwinter in winter.
Timely watering. Appropriate watering. Pay attention to the water and the temperature in the field, which can control the growth of bacteria.
Suitable fertilizer. Lycium barbarum is mainly composed of organic fertilizer, supplemented by microelement fertilizer needed by plants, which can increase the disease resistance of plants.
Trim reasonably and timely.
As the name implies, the root rot of Lycium barbarum does not rot, and the diseased plants show yellow leaves and drooping leaves.
When the conditions are suitable for the second year, the pathogen enters the plant and causes the disease. The pathogen usually spreads with the rainfall and irrigation water. Most of the cases began in the middle and late of April to June, and spread in July and August.

Irrigation. Drip irrigation should be used as much as possible, so as to not only ensure the moisture of the land, but also regulate the watering time.
Apply fertilizer. It is usually based on organic fertilizer, supplemented by other fertilizers. As long as the nutritional balance of the plant can be guaranteed.
This disease is most harmful to leaves. There are white mildew spots and pink spots on the surface of the leaves. In serious cases, the whole plant is white.
The pathogen winter on the surface of the soil and in the winter buds of the diseased branches and shoots. In the next spring, the disease occurs when the plants are in bloom and when the fruits are just beginning to grow. When it's dry, it's more serious than when it's raining. Large temperature difference in the morning and evening is also easy to make the disease happen and spread.

Turn the shallow surface to weed, reduce the reproduction and parasitism of bacteria, and prevent cross infection of plants.
Reasonable use of fertilizer can improve the fertility of the land and make the plants stronger.
In early spring, there were sap flow in the bark of the plant or the wound of the wounded bark. Most of them were foamy. By the time of autumn, there was no glue flow. The bark of the diseased area was burnt black, and the cortex and wood tissue were separated slowly until the plant died.
Gummosis is mostly caused by machine trauma when working in the fields, bark when pruning, and pests.

Choose the right garden shower. It is better to select sandy soil with salt content below 0.33% for Lycium barbarum. &② cultivate strong seedlings to make plants stronger. &(3) suitable fertilization and watering. Lycium barbarum is more sensitive to water and fertilizer, so as to make full use of the fertilizer in the land and give full play to the fertilizer effect as soon as possible. Generally, various kinds of mature farmyard manure are used from late October to mid November. The first watering in spring should be shallow, so that the Lycium barbarum garden does not accumulate more than four hours of clear water.
