How to treat plum tree disease?

Plum tree is widely cultivated in China, and it is a common fruit tree. Its fruit is full and round, exquisitely carved, beautiful in shape and sweet in taste. It is one of people's favorite fruits. So, how to treat the plum tree disease?

1. Red dot disease

Red spot disease and bacterial perforation disease are the main diseases of plum trees. Red-yellow round disease spots can be seen on the leaves when the virus occurs, and the disease spots are slightly raised upward, and serious disease leaves will fall early. Then gradually affect the fruit, the fruit will also have red and yellow round disease spots, seriously affect the growth of the fruit, serious will make the fruit fall. Plum red spot disease often occurs in rainy seasons, and Rain Water is even more serious when it is too long.

Prevention and control: the main prevention and control measures include two kinds, one is to use the method of drug control, spraying pesticides before and after the sprouting of plums, and spraying copper succinate for preventive protection when plums blossom, which will better protect the flowers from being infringed. The other is to clean the orchard in time and thoroughly, bury the fallen leaves and diseased fruit deep in the ground, or take the fallen leaves and diseased fruit outside the garden for burning, which can completely eliminate the germs.

2. Glue disease

The plum branches are mainly harmful to the plum branches. after the damage, the cortex of the plum branches shows a blister-like bulge, and then soft and transparent gum flows out one after another. the gum turns reddish brown to tea brown after contact with air, and becomes hard after drying, and the diseased cortex and xylem turn brown and necrosis. affect the tree potential, some of the branches dry up and even the whole plant dies. The disease occurs all the year round, especially in the hot and rainy season.

Prevention and treatment: strengthen the management of fertilizer and water, make the tree strong and improve the disease resistance of the tree; combine pruning, cut off the sick and dead branches and burn them, and timely do a good job in the prevention and control of branch pests and reduce the wound; scrape off the disease spot and scrape off the disease spot when the shed is heated up, and smear the wound with internal fungicides such as carbendazim, and then apply Bordeaux paste to protect it.

3. Bacterial perforation

Bacterial perforation usually occurs in orchards with high humidity. Plant density, poor drainage and Rain Water are the most prone to this disease, because the bacteria are more likely to be infected in the environment of high temperature and humidity. The infected leaves will form round brown spots, and the fruit will produce water-stained spots. If it is not treated in time, the disease will gradually expand, leading to the early fall of the fruit. Once the disease appears and is not treated, it will lead to no harvest.

Prevention and treatment: for bacterial perforation disease, mainly to prevent, which requires the orchard management staff to strengthen the management of the orchard. Fungicides can be sprayed with carbendazim, carbendazim, carbendazim and other fungicides. When the perforation disease is serious, it will cause tree death, spraying general fungicides does not work, agricultural streptomycin can be sprayed for prevention and control, and if it can not be prevented, animal streptomycin can be sprayed for prevention and control.

In the process of plum tree cultivation, the epidemic situation should be observed at any time so as to prevent it in advance.
