What causes rotten pods in peanuts? Detailed explanation of prevention and control methods
Peanuts are a common cash crop, but during cultivation, rotten pods often occur, which has a major impact on both the yield and quality of peanuts and causes huge economic losses for many growers. So what causes rotten pods in peanuts? And how should they be prevented and controlled? Below, Qinnong.com brings you the causes of rotten pods in peanuts and the prevention and control methods.
1. Disease
When sowing peanuts, the seeds must first be treated. During seed treatment, the outer skin of the peanut seeds may be broken, which not only reduces the germination rate, but also easily allows bacteria to invade, thereby increasing the probability of disease occurrence and causing roots, stems and pods to rot.
Prevention and control methods: 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. During the young pod growth period of peanuts, many insects gnaw on the peanut pods and roots and stems, causing the pods and roots and stems to rot and the plants to die. Some areas are also troubled by rodent damage.
Prevention and control methods: This situation cannot be completely eliminated, which is very headache-inducing. Many farmers mix some insecticide agents with the seeds when sowing, but products on the market are a mixed bag, so it is unclear which one to choose. It is recommended to buy from regular manufacturers.
3. Calcium deficiency
Calcium deficiency can also cause rotten pods in peanuts. When peanuts lack calcium, their shells become very loose, just as when the human body lacks calcium, many bone problems occur. The looseness of the shell causes the pod shell to become thinner and thinner, and without the protection of the shell, disease and moisture slowly invade, resulting in rotten pods.
Prevention and control methods: If calcium is deficient, calcium should be supplemented. During planting, spraying potassium fertilizer and boron fertilizer on the leaves can prevent this phenomenon.
4. Excessive soil moisture
During cultivation, if there is sudden heavy rain or improper watering during management, it can also cause rotten pods in peanuts.
Prevention and control methods: Watering should be carried out according to the degree of dryness and wetness of the soil. The planting soil should be selected 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 rotten pods in peanuts and the prevention and control methods brought to you by Qinnong.com. There are still many causes of rotten pods in peanuts, and this site has only listed a few of them. I hope it can help you. During cultivation, observe carefully and manage conscientiously.
