What Causes Fruit Drop in Honey Peaches? A Detailed Guide to Prevention and Control Methods
The honey peach, also known as the honey peach, is one of the better-known 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 together.
1. Variety reasons
Some honey peach fruit drop is due to genetic reasons of the variety. Fruit drop caused by the 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, vigorous growth, and good quality.
2. Uneven moisture
Peach trees cannot grow and develop without water, but they are also afraid of waterlogging. Once the tree body is flooded for more than 24 hours, leaf drop will occur. If it is flooded for more than 48 hours, plant death may occur. This is because the peach tree root system has a strong absorption capacity and needs sufficient water; once flooded, the roots lack oxygen and cannot avoid plant death, leading to fruit drop. There is more rain in summer, and the groundwater level in peach orchards rises. Growers should promptly dig ditches to drain water and lower the groundwater level. The whole orchard should have a complete ditch system, paying attention to the overall humidity and soil conditions in the orchard. Ditches should be dug as deep as possible to form a relative slope. When planting on flat land, the roots should be raised into ridges to avoid flooding.
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 lead to fruit drop. Check whether the plant root system carries 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 a complete cure. Once an infected plant is found, it must be dug out and burned in time; otherwise, the entire peach orchard may 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 bud break, apply lime sulfur mixture to the trunks where disease may occur, which also has a certain preventive and control effect.
