Control methods of Common Diseases and insect pests in Sugarbeet

Sugar beet is one of the common ingredients on our table, which can be cooked or pickled in many ways. in addition, its sugar content is relative to that of sugarcane. It is also one of the main raw materials for sugar production and an important economic crop. However, it is easy to be disturbed by diseases and insect pests when planting, which often leads to the reduction of its production and quality, affecting economic benefits. Below, the pro-agricultural network brings you the prevention and control methods of common sugar beet diseases and insect pests. Let's take a look.

1. Beet root rot

Root rot is mainly caused by bacterial infection. Spore fungi survive the winter safely in the soil and spread through soil and Rain Water in the coming year. When the disease is serious, it will lead to root rot and death, resulting in reduced yield or no harvest, resulting in great harm.

Prevention and control methods: clean up the weeds and debris before overwintering, then turn the soil deeply, use the sun for disinfection, and carry out a disinfection treatment before planting. After the disease can be used to spray Xianwei, as well as the use of other control methods to irrigate the root.

2. Sugarbeet brown spot

Sugarbeet brown spot is caused by the growth and development of the pathogen, which grows rapidly in the high temperature and humidity environment and does harm in the rainy summer season. When the disease occurs, the pathogen infects the leaves, and the brown disease spots appear in the leaves, which gradually spread and lead to the death of the leaves, resulting in extinction.

Control methods: mainly caused by bacteria carried in the soil, so disinfection of the soil can prevent this disease, the selected Quanling spray disinfection, after spraying with film or straw cover, 2-3 days after ventilation sowing.

3. Sugarbeet blight

The blight is mainly harmful to sugarbeet seedlings or buds, often when the buds are not yet emerging, or when two or three true leaves are grown, brown disease spots appear on the stems of seedlings, and then the cotyledon Hypocotyl changes color and blackens, and finally dies.

Prevention and control methods: it mainly occurs in the environment of low temperature and high humidity, poor soil permeability and poor drainage, so planting needs to pay attention to some conditions. The seeds were treated with chemical dressing before planting, in order to eliminate the germs carried by the seeds, increase the application of phosphate fertilizer, increase the disease resistance of seedlings, and use chemicals to control the disease.

4. Noctuidae

Spodoptera litura harms sugar beet with its larvae. Its larvae feed on the sap of leaves and stems, and yellow-white disease spots appear in the disease parts after feeding, which finally lead to the withering and shedding of leaves and become smooth seedlings, resulting in reduced yield or no harvest.

Control methods: timely autumn or winter ploughing to reduce overwintering pupae, timely cleaning of weeds and reduction of insect eggs in March-April, or artificial egg collection and capture can be used to control. It can also be controlled by chemical methods and sprayed with Bacillus borer or cyanobacteria seedling powder with water during the peak period of night moth.

5. Blue cloth bag beetle

Like the nocturnal moth, the blue cloth bagworm harms the stems and leaves, except that it eats the leaves directly, causing the leaves to be missing, and in serious cases, it eats all the leaves, which also causes smooth seedlings.

Control methods: deep ploughing before planting, elimination of overwintering eggs or larvae, or artificial capture, or spray control with cyhalothrin EC mixed with water.

The above are the common sugar beet pest control methods brought by the pro-agricultural network. I hope it can be helpful to you. For more agricultural knowledge, please pay attention to the pro-agricultural network.
