What about the larvae of the golden needle worm and the underground pests?

Peanut is rich in nutrition, which is an important cash crop in panicum miliaceum and many areas. It is one of the oil crops in people's daily life, especially in the main peanut producing areas in the north, and peanut oil is mostly used as the main edible oil. Rodent damage, waterlogging damage (such as heavy rain and excessive watering), drought (such as drought after full fruit, followed by heavy rain), calcium deficiency (peanut lacks calcium, loose epidermis, easy to be infected by bacteria) and late harvest are all the reasons for peanut fruit rot.

Not discharged in time, causing waterlogging, leading to poor growth and development of peanuts, blocked physiological functions of roots, thin plants, high flowering position, low seed setting rate, poor full fruit rate and increased rotten fruit mildew; Dry weather will lead to the gradual aging of peanut stalks and fruit rot. Fruit will rot. If there are strong plants and developed trees, even if there are insect bites, they can only cause wounds and will not rot. Of course, it is another matter for pests to bite off the roots, but it is also related to the roots. The following picture was taken when I was harvesting peanuts this year.

Drought and rotten fruit: after the peanut is full of fruit, it suddenly encounters severe drought, and the peanut stems gradually age, and then it encounters heavy rainfall or irrigation, and bacteria and water invade the pod, leading to full fruit rot. Everyone's first feeling is being bitten by a bug. Indeed, underground pests do great harm to peanuts, such as grubs, ground tigers, grubs and so on. , especially grubs. If you pull up peanut seedlings, you will find grubs in some rotten fruits.

In the end, it will lead to the color of the pod surface becoming solid, and with the aggravation of the disease, it will lead to the separation of the shell tissue and eventually lead to the decay and deterioration of the fruit. Especially in the environment with high temperature, much rain and high air humidity, stem rot, root rot and other diseases are most likely to occur. Many farmers have tried their best to prevent peanut rot, but this phenomenon still occurs in some areas every year. There are many reasons for peanut rot. Before prevention and control, we should first understand why peanuts rot, and then carry out prevention and control.
