What causes fruit drop in honey peaches? How to prevent and control it

The honey peach, also known as the mi peach, is one of the more famous types of peach and is deeply loved by people. After June, it is the season when honey peaches hit the market, but many growers experience heavy fruit drop in honey peaches, causing serious losses. So how should honey peach fruit drop be prevented and controlled? Let's take a look.

1. Variety reasons

Some honey peach fruit drop is due to genetic reasons of the variety. Fruit drop caused by the inherent characteristics of the variety itself is generally called pre-harvest fruit drop. To solve this, the only option is to choose honey peach varieties with strong disease resistance, vigor, and good quality.

2. Uneven moisture

Peach trees cannot grow and develop without water, but they are also afraid of waterlogging. Once the tree is submerged for more than 24 hours, leaf drop will occur, and if submerged for more than 48 hours, dead plants may appear. This is because the peach tree root system has a strong absorption capacity and needs sufficient water; once submerged, the roots lack oxygen and the plants cannot survive, leading to fruit drop. In summer there is more rain, and the groundwater level in peach orchards rises, so growers should promptly dig ditches to drain water and lower the groundwater level. The whole orchard should have a complete ditch system, and attention should be paid to the overall humidity and soil conditions in the orchard. Ditches should be dug as deep as possible to form a relatively sloped terrain. When planting on flat land, the roots should be planted on raised ridges to avoid being submerged.

3. Pest and disease control

Pests and diseases are also one of the causes of fruit drop in peach trees. Brown rot, white rot, fruit borers, and others cause fruit drop. Check whether the plant roots carry pathogens. If tumor-like protrusions are found, it can be diagnosed as crown gall disease. This disease spreads easily, and there is currently no method for complete eradication. Once an infected plant is found, it must be dug out and burned in time, otherwise the entire peach orchard may all die. If it is other pathogens, apply the appropriate treatment promptly after discovery. In addition, when clearing the orchard in winter, spray the whole orchard with lime sulfur mixture, or before germination, apply lime sulfur mixture to the trunks where disease may occur, which also has a certain preventive and control effect.
