If you are a lover of fruit trees, in EcologíaVerde, we are going to explain how to treat and recognize some of the peach tree diseases or peach. These diseases are caused by different factors such as pathogenic fungi and bacteria that generally affect the plant, producing different symptoms. Some of these are easy to see and recognize such as necrotic spots, wrinkled leaves, and spoiled fruit. Fruit trees in general, in addition to the peach tree, are also very susceptible to contracting pests due to their juicy fruits that attract all kinds of insects that are harmful to their growth. For this reason, at the end of this article, you will also find some of the pests that fruit trees usually have and, specifically, the peach tree.

Main symptoms of Monilinia laxa or monilinia in the peach tree is that you will be able to distinguish it if you see that a powder or mold on peaches whitish in color In addition, if it is not treated quickly, it can also cause cankers on the branches and shoots, as well as defoliation or premature fruit drop.

Even when it begins to develop, it creates a gummosis effect, due to the exudation that it produces when the fresh parts of the tree are infected. We recommend you use ecological fungicides that contain copper or sulfur before spring arrives since, like most pests and diseases, monilia appears when temperatures rise. Here we tell you how to make homemade fungicides for fruit trees. It is also not a bad idea to carry out preventive pruning to aerate the crown and favor the entry of light to avoid high humidity concentrations in the tree.

Xanthomona arboricola pv pruni or black spot

The black spot disease is caused by a bacteria (Xanthomona arboricola pv pruni) which especially affects the peach tree. It starts with a premature and very severe defoliation so it is very easy to recognize. This causes the plant to weaken and as a result the fruits have spots, are very small and not very edible. It also presents other symptoms such as spots on the leaves or yellowing before the fall. In addition, the fruits can also present cracks that, if not treated with fungicides, can end up in rotting before even reaching the maturity phase of the fruit.
