What causes potato rot?

The potato is what everyone commonly calls the potato, and it currently has a wide planting area in our country. But potatoes rotting in the soil during planting has always been a big problem troubling growers. What are the causes of the rot? Below, Qinnong Network will introduce some of the factors that easily lead to this problem.

1. Planting factors

Poor preparation in all aspects before planting potatoes is an important cause. This mainly includes the following aspects. First, the cut pieces of the tubers are too large, so the seedlings after planting are too fragile and rot when they finally form tubers. Second, the cut pieces do not meet the standard; some potato pieces have no sprouts on them and cannot germinate after planting, which also eventually leads to rot. Finally, the seedlings were not stored properly, and the environment was too humid, resulting in too much moisture at planting time and causing rot.

2. Environmental factors

Human regulation in this area is limited, but everyone should know how to regulate it. First, of course, is the issue of moisture and humidity. Potatoes are not suited to overly moist soil, as this causes the underground tubers to absorb too much water, burst through the skin, and rot. Second is the issue of temperature. Everyone thinks temperature has little effect on rot, but that is not actually the case. The stuffy, hot environment formed by excessively high temperatures easily causes potatoes to breed some microorganisms and ferment, leading to rot. So in daily practice, everyone should take measures such as drainage and sun protection.

3. Disease factors

Disease is a frequent factor leading to potato rot. Because potatoes grow underground, some underground pests are difficult to deal with and can easily damage potato growth and cause rot. Second are some diseases, such as ring rot and the like, which start right on the potato tubers as soon as they appear, directly corroding the skin and entering the interior. In this regard, everyone mainly relies on doing good preventive measures in daily practice. Once any change is found in the plants above ground, attention should be raised.

4. Management factors

In this regard, it is enough to be a bit more careful in daily practice, and it is very easy to avoid. First is continuous cropping. Planting potatoes in one piece of land for a long time causes some potato pathogens to accumulate, and planting at this time very easily leads to rot, so the land should be rotated. Second, everyone's daily work after dealing with disease is not in place. Some plants that have become diseased are not taken away from the planting site, causing secondary infection, or when using chemicals, only the diseased bodies are targeted and the surrounding plants are forgotten, planting hidden dangers. Finally, there is the habit of using weeds for compost before planting, which causes some pathogens to remain in the soil.

The above are some causes of potato rot, and everyone should pay attention to all aspects when planting. When cutting pieces, it is best to burn some wood ash, and after cutting, ensure the cut surfaces are covered with wood ash, as this will greatly increase the survival rate of the seedlings. This folk method is experience accumulated over hundreds of years in some regions.
