The Latest Control Methods for Common Peanut Diseases and Pests

Peanut is a food with a very high protein content, and its energy content is also very high. Peanuts are a must-have food for many drinking enthusiasts. In rural areas, many families grow a few mu of peanut fields themselves, because peanuts are grown under the ground, so their diseases and pests will be relatively numerous. Some bacteria and pests in the soil and so on will attack them. So below, the editor will introduce to you the control methods for several common peanut diseases!<

1. Stem rot

This is the most common of the peanut diseases, generally occurring more often at the seedling stage. Once infected with this disease, its leaves will turn dark brown, and slowly the leaves will become dry and rot-like due to lack of water, then gradually spread along the petiole to the whole plant. The longer the disease lasts, the more serious 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 the pathogen in. Another reason is that continuous cropping of the land is too serious, causing pathogens left over from the previous crop in the field 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, finally causing the leaves to dry up, the main root stem to rot, and in the end only a shrunken and shriveled main root remains.

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 above 5 percent, carbendazim should be used to spray the entire field to avoid worse spread of the disease source.<

3. Leaf spot<

Leaf spot is also called black spot, characterized by the production of brown round spots. In the early stage it is not very obvious, and slowly it spreads and enlarges from the center. Yellow-brown mold grows on the leaves. The later the stage, the more serious these fungal spots become, and finally the leaves die.

Control method: Crop rotation can be strengthened. When screening seedlings, try as much as possible to choose 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 by this disease. Once it occurs, carbendazim solution should be used for spraying.<

4. Peanut rust

Peanut rust initially starts from the bottom leaves first. In the early stage of the disease, some yellow spots will appear on the leaves, and then there will be many yellow halos on the leaf edges. When it fully 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. The effect is quite good.<

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