Detailed Explanation of Common Disease Control Methods for Mung Beans

In summer, we all like to cook mung bean porridge, because mung beans have the effect of clearing heat and reducing internal heat. In the hot summer, people's appetites are slightly poor, and at this time drinking a bowl of iced mung bean porridge is simply wonderful. Mung beans are also a common type of whole grain and are extremely popular in the market with a wide range of uses. However, during the planting process, they encounter many pests and diseases that cause losses. Below, Qinnong Network brings you the common diseases of mung beans and their control methods.

1. Damping-off

Damping-off mainly harms seedlings. When seeds begin to sprout, the pathogen invades and lurks in the seedlings, slowly rotting the cotyledons and stems, causing seed rot. In the early stage of the disease, water-soaked lesions begin to appear at the base of the stem, gradually turning yellow-brown and slowly shrinking into a linear shape. The disease develops rapidly, and the plants can collapse before the leaves have even sprouted.

Control methods: When planting, choose a location with higher terrain that is flat and dry. In addition, the groundwater level should be low, and the soil should have good drainage. Avoid planting in low-lying, highly humid environments, and try not to plant in areas where the same type of crop has been grown. Before planting, disinfect the soil. Soak the seeds in warm water, then mix them with a fungicide to sterilize them. When sowing, do so reasonably and not too densely. If diseased plants are found, pull them out and burn them promptly, then spray chemicals for control.

2. Root Rot

When root rot occurs, it often leads to plant death, and it is not easy to notice when the disease strikes. In the early stage of the disease, some leaves begin to turn yellow, and over time the yellowing gradually spreads. Finally, the leaves wither and the plant dies. When the root system is pulled out, it can be found that the underground roots have also rotted.

Control methods: The incidence of the disease is high in low-lying, highly humid areas with low temperatures. Before planting, choose varieties with strong disease resistance. Carry out timely cultivating and weeding, and drain water promptly after the rainy season. In the early stage of the disease, drench the roots with chlorothalonil, or spray with Fulingling.

3. Powdery Mildew

Powdery mildew is a common disease of crops and not only harms mung beans. It spreads through spores. Diseased plants and plant residues from the previous year overwinter in the planting field, and in the following year they spread by wind or other means. When the disease occurs, lesions appear on the leaves. As the lesions expand, white powder appears on them, causing the leaves to curl and become deformed. In the later stage, small black particles appear within the white powder.

Control methods: Before planting, gather diseased plants and plant residues and burn them, then plow the soil deeply and expose it to the sun to whiten it, preventing the spores from overwintering. When the disease occurs, remove the diseased plants, then spray with wettable powder of Ningnan for control.

4. Insect Pests

Mung beans have many insect pests. Common ones include cutworms, scarab beetles, and aphids. These insects all gnaw on the tender branches, tender leaves, and root systems of the plants or suck the sap from stems and leaves, ultimately causing the plants to wither and die or causing reduced yields, with great harm.

Control methods: Insect pest control is mainly based on chemical control. Strengthen field management, and also spray chemicals regularly for control in normal times. When insect pests are found, deal with them promptly.
