What are the common pest and disease control methods for peanut cultivation?

Peanut is a food with a very high protein content, and its energy content is also very high. Peanuts are an essential food for many drinking enthusiasts. In rural areas, many families grow a few mu of peanuts themselves, because peanuts are grown underground, so they have relatively more pests and diseases, such as some bacteria and pests in the soil that will attack them. So below, the editor will introduce the control methods for several common peanut diseases!<

1. Stem rot

This is the most common of peanut diseases, generally occurring more often at the seedling stage. Once infected with this disease, its leaves will turn dark brown, and gradually the leaves will become dry and rotten due to lack of water, then slowly spread along the petiole to the whole plant. The longer the disease lasts, the more severe the symptoms become, and finally it directly causes the leaves to wither and die.

Control method: The main source of spread of stem rot is the seed; the seed brings in the pathogen. Another reason is that continuous cropping of the land is too severe, causing pathogens left over from the previous crop in the soil to attack our peanuts. We can use carbendazim solution and thiophanate-methyl solution for spraying treatment.<

2. Root rot

Root rot is a disease that mainly harms the roots and root stems. After the root stem is infected, it will appear water-soaked, and then the roots will slowly change color, becoming darker over time, eventually causing the leaves to dry up, the main root stem to rot, and finally leaving only a shrunken and shriveled main root.

Control method: We can strengthen the requirements for crop rotation. Carry out reasonable crop rotation. When selecting and sun-drying seeds, pay attention to using carbendazim solution for soaking and seed dressing. If the incidence rate reaches more than 5 percent, carbendazim should be used to spray the whole field to avoid worse spread of the disease source.<

3. Leaf spot disease<

Leaf spot disease is also called black spot disease. It is characterized by the production of brown round spots. In the early stage it is not very obvious, and then it slowly spreads and enlarges from the center, with yellow-brown mold growing on the leaves. The later it gets, the more severe these fungal spots become, and finally the leaves die.

Control method: Crop rotation can be strengthened. When screening seedlings, try to select varieties with strong disease resistance. In addition, during the growth process of peanuts, this disease has the highest incidence rate in July and August. During this period, focus on observing whether there is infection with this disease. Once it occurs, carbendazim solution should be used for spraying.<

4. Peanut rust disease

Peanut rust disease initially starts with the leaves at the bottom getting infected first. In the early stage of the disease, some yellow spots will appear on the leaves, and then there will be many yellow halos at the edges of the leaves. When it completely cracks open, rust-colored powder will be exposed. If the symptoms are severe, it will directly dry up and die.

Control method: As soon as the disease is discovered, it must be treated immediately. Use chlorothalonil solution and triadimefon solution for combined spraying treatment, and the effect is quite good.<

The above are the common pest and disease control methods for peanut cultivation. Have you learned them? The degree of control of peanut diseases mainly depends on seed selection and the quality of the land. Of course, poor management will also cause a series of symptoms to appear.
