1、 Scab disease

Scab is one of the main diseases of peach trees, which mainly occurs from May to July. It is easy to be infected in rainy and humid environment. It mainly endangers fruits and tree tops. Every winter, the tree tops infected with diseases should be cleaned in time, and the orchards should be cleaned to reduce the source of diseases as much as possible. In the growth stage of peach trees, carbendazim, zineb and chlorothalonil should be sprayed for prevention, which can reduce the infection rate

2、 Anthrax

The disease is mainly susceptible to infection when there is a lot of rain in autumn, which mainly endangers the fruit. When the fruit is infected, there will be water stains on the surface, and the disease spots will expand and become yellowish brown, which will eventually lead to fruit rot and fall off. During the management period, we should strengthen the management of fertilizer and water to improve the disease resistance of peach trees. In rainy season, the accumulated water shall be drained in time and the ventilation shall be strengthened. In winter, we should clean up fallen leaves and diseased branches. Peach trees should be bagged in time during the growth stage, and chlorothalonil, mancozeb, thiophanate methyl and other chemicals can be sprayed during the disease

3、 Gum disease

Gum disease is also one of the common diseases of peach trees. It begins to attack when the temperature is slightly higher. It mainly endangers the branches and stems of peach trees. When it occurs, the branches and stems are easy to have small bumps. Generally, the glue will not flow in that year, and the small bumps begin to flow in the second year. The management of fertilizer and water should be strengthened to improve the disease resistance. In the season of discovery, agents such as mancozeb and benomyl wettable powder should be sprayed, and drugs should be used alternately to avoid drug resistance

4、 Mosaic disease

Mosaic disease does great harm to peach trees. It is mainly infected during grafting, and aphids and mites will also spread the disease. Once the fruit is infected, the growth rate will slow down, the pulp will become unsweetened, and there will be yellow leaves and rolling leaves. If the disease is found, it should be cleaned up as soon as possible, and the pest control of orchards should be strengthened
