What are the latest causes of pepper plant death?

Pepper cultivation is very common in China, and the planting area is also very large. And although there are many people who grow peppers, various problems often arise when growing peppers. Among them, dead seedlings are a very common one, and dead seedlings can seriously affect pepper yield and reduce economic benefits. So what causes pepper plant death? Today the editor will give you a brief introduction. Let's take a look below!

1. Sudden clearing after heavy rain

When growing peppers, if heavy rain is followed by sudden clearing, especially in summer, then the soil moisture evaporates very quickly. Also, because the soil water content is very high after heavy rain, the soil becomes oxygen-deficient, and the absorption capacity of the roots decreases. Therefore, the water absorption rate of the roots is far slower than transpiration, causing the pepper plants to rapidly become short of water, and the seedlings show a wilting state. This situation is also called false death. If the false death state cannot recover as soon as possible, then all parts of the seedling will be severely short of water, causing the pepper plants to completely die.

2. Excessive watering

Watering is essential when growing peppers, but if there is too much watering or if water accumulates in the soil after heavy rain, then it can easily lead to soil oxygen deficiency, and the carbon dioxide content will also increase as a result. This causes the reducing effect of the soil to become too strong, and it is also prone to producing various toxic substances such as hydrogen sulfide. This is very unfavorable to the protoplasm of the pepper seedling roots. The absorption function of the pepper roots will also be inhibited as a result, and the roots are also prone to various adverse phenomena such as poisoning and root rot. And when the seedlings lack nutrients and water, dead seedlings naturally tend to occur.

3. Poor disease resistance

The disease resistance of peppers is usually not very strong. If the peppers are injured during their growth for various reasons, for example, due to farming operations, or because strong winds and heavy rain cause the plants to rub against each other or lodge, then the disease resistance of the peppers will be greatly weakened, leading to a greater chance of pathogen spread. If there is also a high-temperature and high-humidity environment, then it will also cause pathogens to reproduce rapidly, thereby triggering a large number of pepper dead seedlings. Therefore, everyone must pay attention to doing a good job in pepper protection, reducing wounds, enhancing the disease resistance of peppers, and reducing dead seedling phenomena.

4. Other causes

In addition to the above causes, diseases can also cause infectious dead seedling phenomena in peppers. For example, damping-off disease, bacterial wilt, and so on. Pathogens can spread through many routes, such as air and rainwater, causing the pepper development cycle to be greatly shortened, thereby triggering large-scale dead seedlings. In addition, improper fertilizer application can also cause pepper dead seedlings. When applying organic fertilizer, if it is not fully decomposed or the fertilizer concentration is too high, it can easily cause pepper seedlings to wilt, disrupt the metabolic function of peppers, and cause various adverse phenomena such as pepper dead seedlings.

The above is a brief introduction to what causes pepper plant death. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
