What are the common diseases of yellow peach?

When growing yellow peaches, various diseases always occur, harming both microorganisms and pests, and relatively speaking, the harm from microorganisms is greater. So which diseases are prone to occur in yellow peach trees? Today Qinnongwang will introduce several of them so everyone can understand how these diseases develop.

1. Peach anthracnose

This is a disease caused by a pathogen, mostly concentrated on the fruit, and it is a disease that easily expands. It mostly occurs in the high-temperature and humid environment of the summer rainy season. When it appears, the fruit becomes dull and lusterless, slowly withers and hardens, and finally becomes completely shriveled. In severe cases, the branches quickly wither and the tree dies. When discovered, first remove the affected parts and eliminate the pathogen, then spray for treatment with 3000 times 25% Amistar or 800 times 72% Dupont Curzate.

2. Peach brown rot

This is the disease most likely to appear on yellow peach fruit. Once it appears, it means the fruit will necrose. It mostly occurs in low-temperature and humid environments, and is generally caused by fruit being corroded by moisture because the fruit trees are too densely planted. When the disease occurs, the top of the fruit begins to turn brown and is accompanied by mold, and over time it gradually corrodes downward until the entire fruit rots. At this point it can also easily spread to the branches and trunk. For this disease, 50% iprodione wettable powder 1000-2000 times solution can generally be sprayed for prevention, with emphasis on spraying the susceptible parts.

3. Pests and diseases

This is a problem no fruit tree can avoid. The more common pests and diseases of yellow peach trees include peach fruit borer, aphids, and stink bugs, all of which are highly harmful. When they occur, the leaves usually begin to curl and turn yellow, and some also rot. After opening them, the pests and diseases can be clearly seen. It is generally recommended to burn such leaves to reduce the source of pests. A commonly used control agent is carbendazim 800 times solution, and the effect is still acceptable.

4. Peach bacterial shot hole

This is the most harmful disease because it harms the entire plant, so special attention must be paid to it. It is generally caused by poor antiviral measures in the early stage, and as the temperature rises, the disease gradually develops. The symptoms are cracking of the bark, while in some cases the leaves develop small holes and begin to wither and necrose. This disease needs to be treated with pesticides. For mature trees, agricultural streptomycin sulfate 4000 times solution can be used, and for sprouting trees, 72% agricultural streptomycin sulfate wettable powder 3000 times solution can be used. Both effects are still acceptable.

The above are several common diseases of yellow peach trees. During planting, various disease prevention measures must be done well in the early stage. If you wait until the disease occurs before treating it, there will still be various losses. The remaining branches of affected plants must be burned to avoid secondary infection caused by them.
