Prevention and Control of Cherry Gummosis

Gummy disease is an important disease of cherry, most garlic occurs in spring, this disease gives growers a headache, light causes tree weakness, serious causes branch thinning gradually withered, resulting in great losses. So how to prevent and cure the disease? Come and have a look with the editor.

Symptoms of the disease

Gummy disease mainly occurred on the trunk and branches of cherries, and the trunk disease was the most prominent. In the early stage of the disease, the disease swelled and continued to flow out translucent yellow gum, especially after rain. The gum will turn reddish brown after contact with the air, and sometimes several glue beads are connected together to form round irregular glue spots of different sizes, which are jelly-like and form hard glue blocks after drying. After specific infection, the epidermis and xylem turn brown and rot, resulting in the weakening of the tree and, in serious cases, the withering of the branches or the whole plant.

II. Causes of occurrence

There are many reasons for cherry glue flow, such as rootstock incompatibility, the wound is difficult to heal after grafting, there will be glue flow phenomenon. The plants with weak tree potential are also very easy to flow gum, and the plants with poor tree potential have poor nutrient circulation, resulting in insufficient distribution of nutrients, and some nutrients reach the position of poor formulation, resulting in lateral outflow. The tree body hangs a large amount of fruit, nutrition consumption is relatively large, or overpruning, unreasonable cutting and other reasons will also cause glue flow. The phenomenon of gum flow will also occur when the root system is infected by diseases; when the plant is infected with bacterial diseases, it will occur with the expansion and deepening of necrotic spots.

III. Prevention and control methods

The prevention and control of gum disease should be done from many aspects, first of all, strengthen fertilizer, water and soil management, pay attention to the application of organic fertilizer and phosphorus and potassium fertilizer appropriately, control the application of nitrogen fertilizer in the middle and later stage, strengthen the tree potential, and do a good job of drainage in the rainy season to reduce humidity. In the peak period of leaf growth, phytonutrients can be used to promote its growth, increase chlorophyll and enhance the nutritional capacity of plants. Pruning should be reasonable, adjust the contradiction between vegetative growth and reproductive growth, ensure tree potential temperature, and timely apply fungicides to promote wound healing and reduce bacterial infection. It is necessary to clear the garden in time after cherry fruit picking, and the plant needs to replenish nutrition in time to restore the tree potential and reduce the phenomenon of gum flow.

The above is the introduction of the prevention and control methods of cherry gum disease. I hope it can help you. If you want to know more about it, please follow us.
