Causes and control methods of the latest dead peanut seedlings

Peanut is an important oil crop in China, with high economic value, and with the continuous development of planting, the planting area of peanut is becoming larger and larger, but the phenomenon of dead seedlings often occurs during planting, which seriously affects the yield of peanuts. In serious cases, farmers will lose harvest, and the phenomenon of dead peanut seedlings will seriously affect the production of peanuts. So what is the reason for the death of peanuts? How to prevent and cure it? Let's take a look.

1. Seed problem

The quality of the seeds purchased during sowing is poor, such as aged seeds, rotten seeds, etc., or the seeds are in storage, because the storage environment is not easy, resulting in mildew of seeds or eating by rats, resulting in adverse emergence of peanuts. Some don't sprout. It is weak after emergence and dies slowly at the back.

Prevention and control methods: to buy seeds from regular manufacturers, be sure to check the production period and the quality of the seeds, and if you keep your own seeds, you should carefully select seeds with larger particles, no damage, and no mildew.

2. Continuous cropping and continuous cropping

In some areas, due to perennial planting of peanuts and limited planting area, there are no rotation measures, and perennial continuous cropping leads to serious continuous cropping, which leads to more bacteria in the soil, and is extremely resistant to pesticides, which is extremely difficult to control. This leads to the death of peanut seedlings.

Control methods: reasonable crop rotation, can rotate with soybean, corn and wheat for 2-3 years, continue to plant peanuts, can reduce the phenomenon of dead seedlings.

3. Disease

Diseases are the main causes of peanut death, such as root rot, stem rot, bacterial wilt and so on. These diseases will lead to seedling yellowing in the early stage, and finally die with the development of the disease.

Prevention and control methods: disinfection and seed dressing should be carried out before planting, the germs carried by the seeds should be eliminated, the soil can be disinfected once before planting, and the chemical should be sprayed in time to prevent and cure the disease, so as not to miss the best treatment time and cause the seedlings to die.

4. Insect pests

Like diseases, peanut seedlings are mainly caused by low pests, such as grubs, which are harmful to a large area, mainly lurking in the ground, constantly nibbling on the roots of seedlings, resulting in dead seedlings, if there are no dead seedlings. The fruit will be eaten clean at a later stage.

Control methods: turn the soil deeply before planting, dig out the underground pests and eggs, use the sun to kill them, sprinkle lime powder, pour water once, cover the whole ground with the ground, bury the soil around the plastic film, and let the pests die due to lack of oxygen. When the pest is serious, chemical root irrigation should be used to control it.

5. Drug damage

In the control of diseases and insect pests or weeding, improper use of pesticides will also cause the death of seedlings, herbicides is one of them, seedlings first yellowed, and then slowly withered, and some leaves will be zoomed.

Prevention and control methods: there is no special solution to drug damage, only reasonable and standardized use of chemicals, found that early drug damage, can be calculated to spray foliar fertilizer, alleviate death, found later, only seed destruction, replanting.

The above are the causes and control methods of peanut death. I hope I can help you. If you want to know more about peanut planting, please follow us.
