What causes rotten peanut pods? A detailed guide to the latest solutions

During the pod-setting and maturity stage of peanuts, pod rot and rotten pods often occur for various reasons, causing reduced peanut yields and lower quality, and resulting in considerable economic losses for farmers. So what causes rotten peanut pods? How should they be dealt with? Let's take a look.

I. Causes of rotten peanut pods

1. Waterlogging damage

In the late growth stage of peanuts, that is, when they are close to maturity, they suffer waterlogging damage. If the peanut root system and pods remain in a moist environment for a long time, root rotting will occur, which leads to premature aging and death of the plants as well as rotten pods.

2. Insect damage

When underground insect pests of peanuts occur severely, such as white grubs and mole crickets, the peanut pods are gnawed on during the pod expansion and late maturity stages, which can also cause peanuts to rot due to infection by pathogens.

3. Premature aging

Premature aging caused by the premature decline and death of the plants leads to insufficient calcification of the peanut pod shell, resulting in poor development of the peanut pods and premature aging of the pods, which also makes the pods prone to rotting in the later stage.

4. Diseases

Diseases include not only fungal, bacterial and viral diseases, but also physiological diseases caused by nutrient deficiencies in the field, all of which may lead to rotten peanut pods. For example, after peanuts are infected with root rot or southern blight, the root system becomes very weak, resulting in the whole plant being unable to supply nutrients and thus rotten pods.

II. Solutions

1. Prevent soil-borne diseases

Diseases are an important factor causing rotten peanut pods, and the most common diseases are soil-borne ones. For example, white grubs can reproduce year after year in a suitable environment, and their eggs are difficult to kill by freezing in winter. Secondly, fungal and bacterial diseases likewise break out because of continuous cropping. The best way to reduce soil-borne diseases is to avoid continuous cropping. In addition, soil disinfection can be carried out by broadcasting carbendazim before sowing, which can effectively prevent and control a variety of soil-borne diseases.

2. Balanced fertilization

Using a single fertilizer is not conducive to balanced nutrients in the field, so balanced fertilization is very necessary. Excessive and overly single use of chemical fertilizers can easily cause nutrient deficiency symptoms, so organic fertilizer or farmyard manure should be applied, which can improve soil structure and reduce the rate of rotten pods.

3. Avoid water accumulation in the field

Water accumulation is also one of the important causes of rotten peanut pods, so in peanut production it is essential to avoid drought and waterlogging disasters in the field and to do a good job of field drainage. At the same time, according to the differences between northern and southern China, appropriate planting methods should be adopted. The south has more rain, so ridge cultivation is recommended, which can effectively avoid waterlogging damage; the north is drier, so flat-bed planting can be used.

4. Do a good job of pest and disease control measures

In order to reduce the occurrence of pests and diseases in the field, seed dressing with chemicals can be used at sowing time, which can effectively prevent the occurrence of pests and diseases. In addition, during the growth period, attention should be paid to the control of pests such as white grubs and mole crickets, which can be controlled by drenching or root irrigation with chlorpyrifos or clothianidin. During the peanut growth period, fungicides should be sprayed at least 2 times, and when applying chemicals, combining them with brassinolide and amino acid foliar fertilizer has a good promoting effect on root recovery.
