The latest common diseases of mung bean and their control methods

We all like to boil porridge with mung beans in summer. At this time, because mung beans have the effect of clearing away heat and reducing fire, it is hot in summer and people have a slightly poor appetite. It is not too cool to drink a bowl of ice Congee with Mung Bean Congee at this time. Mung bean is also a common cereal, which sells very well in the market and has a wide range of uses, but it will encounter a lot of diseases and insect pests in the planting process, resulting in losses. The following pro-agricultural network brings common diseases and control methods of mung beans.

1. Sudden collapse disease

The disease mainly harms the seedlings. When the seeds begin to sprout, the pathogen invades and lurks in the seedlings, slow cotyledons and stems rot, resulting in rotten seeds. In the early stage of the disease, watery spots began to appear at the base of the stem, gradually turned yellowish brown, slowly shrank into a linear shape, the disease developed rapidly, and could lodge before the leaves sprouted.

Prevention and control methods: choose high-lying, flat and dry places when planting, in addition, the groundwater level should be low, and the drainage of the soil should be good, avoid planting in low-lying and high-humid environments, and try not to plant similar crops. Disinfect the soil before planting, soak the seeds in warm water, then use fungicides to stir and sterilize, sowing should be reasonable, should not be too dense, diseased plants should be pulled out and burned in time, and then spray chemical control.

2. Root rot

Root rot disease often leads to plant death, and it is not appropriate to find that some leaves begin to yellowing at the initial stage of the disease, and with the gradual expansion of time, the left rear leaves wither and the plant dies, and the root system is pulled out. Underground roots and decay can be found.

Prevention and control methods: high incidence of planting in areas with low-lying, high humidity and low temperature, selecting varieties with strong disease resistance before planting, timely ploughing and weeding, timely drainage after rainy season, root irrigation with chlorothalonil at the initial stage of the disease, or spraying with carbendazim.

3. Powdery mildew

Powdery mildew is a common disease of crops, not only harmful to mung beans, it is the transmission of spores, the residual plants of the first year overwintered on the planting ground, to be spread by wind or other means in the coming year. The disease is caused by the appearance of disease spot in the leaf, and with the expansion of the disease spot, the disease spot appears white powder, which makes the leaf curl up deformity, and small black particles appear in the white powder in the later stage.

Control methods: burn the diseased and residual plants before planting, and then turn the soil deeply to prevent the spores from overwintering, remove the diseased plants when the disease occurs, and then spray rust rather wettable powder to prevent and cure.

4. Insect pests

There are many pests in mung bean, such as small tigers, beetles and aphids. These insects eat the twigs and leaves of the plant and the root system or suck the sap of the stem and leaf, resulting in the withering and death of the plant or the reduction of yield.

Prevention and control methods: pest control is based on chemical control, strengthen field management, spray chemical control regularly in peacetime, and deal with pests in time when they are found.

The above are the common diseases and control methods of mung bean brought by the pro-agricultural network. I hope the above can help people in need and learn more about agriculture. Please pay attention to the pro-agricultural network.
