Common Diseases and Control of the Latest Cherry
Cherry, also known as European sweet cherry, originally produced in Europe, was favored by many people after it was introduced into China, and more and more people began to plant it. In fact, the method of growing cherries is similar to that of cherries, because the difference is very small, but different diseases will be encountered in the planting process. We don't know exactly how to solve it, so today the editor brings you the common diseases and control methods of cherries. Let's take a look at it.
1. Cherry brown rot
Symptoms: Cherry brown rot is the most important disease that harms cherries. It is also known as perforation, which mainly harms the leaves of fruits. At the beginning of the disease, needle-sized purple spots will be formed on the leaves, and then will gradually expand and extend, and in the later stage, some spots will extend together to form brown patches. Black dots gradually appear on the plaques, which are conidia. Finally, the plaque dries up and falls off a small hole in the leaf, which in severe cases can lead to early defoliation. It affects the growth of trees and reduces the yield of cherries seriously.
Prevention and control methods: clean up the fallen leaves, clean up the diseased and residual branches, reduce or eliminate the pathogens overwintering, and strengthen the management of the orchard. Improve the site conditions of the orchard, increase the growth of the tree and improve the disease resistance of the tree. It can be controlled by spraying mancozeb and other chemicals before Xiehua and fruit picking.
2. Cherry leaf spot
Symptoms: Cherry leaf spot is mainly harmful to cherry leaves, the leaves will form brown-purple and nearly round patches between the veins at the initial stage of damage, and gradually necrosis. Pink mildew spots will appear on the back of the leaves, and their harmful symptoms are not much different from those of brown-purple patches, and the disease spots will gradually expand and extend. After clamping, the formation of large patches will make the leaves begin to die and fall in a large area. So that fruit trees can not carry out effective photosynthesis, can not meet the nutrition needed for growth, and sometimes petioles and fruits will be damaged, and in serious cases, the whole tree will die due to lack of nutrition.
Prevention and control methods: pay attention to the hygiene of the orchard, disinfect the orchard in time after harvest in winter, remove bacteria effectively, concentrate on cleaning up the diseased remains and fallen leaves, and burn them. Because most of the leaf spot pathogens are parasitically attached to the soil, the disease remains in the overwintering, when the Beginning of Spring will appear to harm fruit trees, chemical control and brown rot are similar.
3. Cherry gum disease
Gummy disease is also one of the most common diseases in the growth of cherries, which mainly occurs in the wound of the branch or the gum from the dead tissue of the branch. The disease has a chance to occur after the tree begins to sprout, and no matter what stage it is, the disease occurs most frequently. The disease will be a little in the middle, the cortex and wood parts will gradually rot, and then produce other germs, which are very likely to cause other diseases, causing the tree to grow weaker and weaker, and even the whole plant will die in serious cases.
Prevention and control methods: after the seedling sprouting, it is necessary to apply a fixed amount of wet organic fertilizer to prevent and control natural disasters, such as freezing, drought and waterlogging. Enhance the disease resistance of the tree, paint all the lower parts of the trunk white, prevent and cure burns, and strengthen the prevention and control of other diseases and insect pests, especially the wounds caused by some insect pests, we should also pay attention to prevent mechanical damage when pruning.
The above are the more common diseases when planting cherries, pay attention to the prevention and control of diseases is every grower must do a good job. Neglect or lack of careful management will lead to a serious reduction in cherry production, in fact, the disease is caused by improper orchard management, except for very few varieties. When planting, we must carefully manage every tree in the orchard. Only in this way can we ensure the normal growth and development of fruit trees.
