Detailed Guide to Controlling Common Diseases of Yellow Peaches
It is currently the marketing season for yellow peaches. Yellow peaches are not only sweet in taste and soft and glutinous in texture, but also have a certain nutritional value. Besides being eaten fresh, they can also be processed into canned food. During yellow peach cultivation, they are attacked by many diseases. So what common diseases do yellow peaches have? How should they be controlled? Let's take a look.
I. Common Diseases of Yellow Peaches
1. Bacterial shot hole disease of yellow peach: This disease mainly overwinters in the diseased tissues of yellow peach branches. After the temperature rises in the following spring, the bacteria in the diseased tissues begin to become active. After the yellow peach plants bloom, it causes the epidermis to crack, and the lesions overflow from the diseased tissues. The pathogen is also spread by insects, wind and rain.
2. Peach leaf curl of yellow peach: The occurrence of this disease is very closely related to weather changes. When yellow peach buds break, the temperature is relatively low and lasts for a relatively long time, and the air humidity is relatively low, so peach leaf curl is very likely to occur. However, once the temperature exceeds 21 degrees, the disease will no longer spread.
3. Anthracnose of yellow peach: It is one of the main diseases of peach trees. Generally, under high-humidity conditions, the disease is more severe. When yellow peaches are in the flowering and fruiting period and are exposed for a long time to low temperatures and abundant rain, the disease occurs.
4. Brown rot of yellow peach: This disease generally occurs during periods of low temperature, more precipitation and higher humidity. The flowers of yellow peach are the most susceptible to infection.
II. Control Techniques
1. Select excellent varieties
To ensure yellow peaches suffer fewer diseases, choosing a good variety is relatively key. When purchasing, try to choose varieties with strong disease resistance and suitable for local planting, and carry out disinfection treatment properly.
2. Do a good job in field management
Usually, promptly clean up fallen leaves and weeds in the orchard to reduce the pathways for pests and diseases, which can play an excellent preventive role.
3. Reasonable fertilization
If yellow peaches are to have fewer diseases during growth, reasonable fertilization is also a key point, because adequate fertility can improve the ability of yellow peach plants to resist pests and diseases. The fertilizer should mainly be organic fertilizer, with an appropriate increase in phosphorus and potassium fertilizer, to improve the disease resistance of the plants.
4. Chemical control
When diseases occur, chemical control must be used to prevent the condition from spreading. Commonly used agents include mancozeb, carbendazim, chlorothalonil, etc.
