A Detailed Explanation of the Causes of Peanut Pod Rot and Control Methods
Peanut is a common cash crop, but pod rot often occurs during cultivation, which has a major impact on peanut yield and quality and causes huge economic losses for many growers. So what causes peanut pod rot? And how should it be controlled? Below, Qinnong Network brings you the causes of peanut pod rot and control methods.
1. Disease
When sowing peanuts, the seeds must first be treated. During seed treatment, the outer skin of the peanut seed may be broken, which not only reduces the germination rate but also easily allows bacteria to invade, thereby increasing the chance of disease and causing roots, stems and pods to rot.
Control method: Pay attention to the method during seed treatment. If the seed coat is accidentally broken, dry it in time, but do not store it for a long time. Pay attention to disinfecting and sterilizing the soil to minimize sources of pathogens and not harm the health of the peanuts.
2. Underground pests
Underground pests are most common in rural areas, and this situation often troubles farmers greatly. Many insects feed on peanut pods and roots and stems during the young pod growth stage, causing pods, roots and stems to rot and the plants to die. Some areas are also troubled by rodent damage.
Control method: This situation cannot be completely eliminated and is very troublesome. Many farmers mix some insecticide agents with the seeds when sowing, but insecticides on the market are a mixed bag, so it is hard to know which to choose. It is recommended to buy from regular manufacturers.
3. Calcium deficiency
Calcium deficiency can also cause peanut pod rot. When peanuts lack calcium, their shells become very loose, just as calcium deficiency in the human skeleton causes many bone problems. The loose shell causes the pod shell to become thinner and thinner. Without the protection of the shell, disease and moisture gradually invade, resulting in pod rot.
Control method: If calcium is deficient, calcium should be supplemented. During cultivation, spraying potassium fertilizer and boron fertilizer on the leaves can prevent this phenomenon.
4. Too much soil moisture
During cultivation, sudden heavy rain or improper watering during management can also cause peanut pod rot.
Control method: Water according to the degree of soil dryness and moisture. The planting soil should be chosen to be loose and well drained, which is beneficial for irrigation and drainage management. After rain, drain water in time to reduce moisture.
The above are the causes of peanut pod rot and control methods brought to you by Qinnong Network. There are still many causes of peanut pod rot, and this site has only listed a few of them. We hope this can help you. During cultivation, observe carefully and manage diligently.
