4. Mosaic disease

1. Scab disease: It mainly occurs from May to July and damages fruits and tree tops. Orchards should be cleaned in winter and pesticides should be sprayed during the growth stage of peach trees. 2. Anthracnose: This disease is easily infected in rainy seasons and mainly damages fruits. Peach trees should be bagged in time, and chlorothalonil, mancozeb and other chemicals should be sprayed during the onset of the disease. 3. Gum disease: It mainly harms tree trunks and must be prevented and controlled by spraying mancozeb in time. 4. Mosaic disease: Once discovered, diseased plants should be cleaned up in time and pest control should be strengthened.

1. Scab

Scab is one of the main diseases of peach trees. It mainly occurs between May and July. It is easy to be infected in rainy and humid environments. It mainly damages fruits and treetops. Every winter, disease-infected treetops should be cleaned up in a timely manner and orchards should be cleaned to reduce the source of the disease as much as possible. During the growth stage of peach trees, pesticides such as carbendazim, zinc, and chlorothalonil should also be sprayed for prevention, which can reduce the infection rate.

2. Anthracnose

This disease is mainly infected when there is a lot of rain in autumn, and mainly harms fruits. When the fruit is infected, there will be water-soaked lesions on the surface, and the lesions will turn yellow-brown as they expand. , which will eventually cause the fruit to rot and fall off. During the management period, fertilizer and water management should be strengthened to improve the disease resistance of peach trees. During the rainy season, accumulated water should be drained promptly and ventilation should be strengthened. In winter, fallen leaves and diseased branches should be cleaned up. 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 period to prevent and control the disease.

3. Gum disease

Gum disease is also one of the common diseases of peach trees. It starts to attack when the temperature is slightly higher. It mainly harms the peach branches. When the disease occurs, the branches are prone to small bumps. Generally, there will be no glue flow in the first year, and small bumps will start to flow glue in the second year. This disease requires strengthening fertilizer and water management to improve disease resistance. During the discovery season, agents such as mancozeb and benomyl wettable powder should be sprayed, and the drugs should be used alternately to avoid the development of drug resistance.

4. Mosaic disease

Mosaic disease is relatively harmful to peach trees. It is mainly infected during grafting, and aphids and mite pests can also spread this disease. Once the fruit is infected, the growth rate will slow down, the pulp will become less sweet, and the leaves will turn yellow and curled. If this diseased plant is found, it should be cleaned up as soon as possible, and pest control work in the orchard should be strengthened.
