Causes and Solutions of rotten Peanut fruits

In the podding and ripening period of peanuts, rotten pods and fruits often occur due to various reasons, resulting in reduced production and quality of peanuts, and also caused a lot of economic losses to farmers. So what is the cause of rotten peanuts? How to solve it? Let's take a look.

First, the cause of rotten peanut fruit

1. Waterlogging damage

It suffers from waterlogging in the later stage of peanut growth, that is, when it is about to mature. The root system and fruit of peanut are in a humid environment for a long time, then the root retting phenomenon will occur, which will lead to premature senescence, death and fruit rot.

2. Insect pests

When peanut underground pest occurs seriously, such as grub and mole cricket, it will also lead to peanut rot due to bacterial infection when it is eroded by insect pests in the stage of peanut fruit expansion and late ripening.

3. Premature senility

Premature senescence caused by premature decay of plants will lead to insufficient calcification of peanut fruit, lead to poor development of peanut fruit, early aging of peanut fruit, which also makes the fruit easy to rot in the later stage.

4. Disease

Diseases include not only fungal, bacterial and viral diseases, but also physiological diseases caused by element deficiency in the field, which may lead to peanut fruit rot. For example, the root system of peanut infected with root rot and white silk disease is very weak, which leads to the nutrition supply of the whole plant and rotten fruit.

II. Solutions

1. Prevention of soil-borne diseases

Disease is an important factor causing rotten peanut fruit, and the most common diseases are soil-borne diseases, such as grubs can reproduce in a suitable environment, insect eggs are difficult to freeze to death in winter, and secondly, fungal bacterial diseases will also break out because of repeated cropping. The best way to reduce soil-borne diseases is to avoid continuous cropping. In addition, it can also carry out soil disinfection and spread carbendazim before sowing, which can effectively control a variety of soil-borne diseases.

2. Balance of fertilization

Single fertilization is not conducive to the balance of nutrients in the field, so balanced fertilization is very necessary, chemical fertilizer is too single, it is easy to cause element deficiency, so the application of organic fertilizer or farm fertilizer can improve soil structure and reduce the rate of rotten fruit.

3. Avoid stagnant water in the field

Stagnant water is also one of the important causes of rotten peanut fruit, so in peanut production, we must avoid drought and waterlogging in the field, do a good job in field drainage, and adopt appropriate planting methods according to the differences between the north and the south of our country. Rain Water is more in the south. It is suggested that ridge cultivation can effectively avoid waterlogging damage, and flat beds can be planted in the north.

4. Do a good job in the control of diseases and insect pests

In order to reduce the occurrence of diseases and insect pests in the field, seed dressing can be used during sowing, which can effectively prevent the occurrence of diseases and insect pests. In addition, attention should be paid to the control of grubs, mole crickets and other pests in the growing period. Chlorpyrifos or thiazolamine can be used or root irrigation control. During the growing period of peanut, fungicides should be sprayed at least twice, and the combination of brassinolide and amino acid foliar fertilizer can promote the recovery of root system.
