How to prevent and control severe root rot in ginseng and other economic crops

Root rot is one of the most severe diseases of ginseng and other economic crops. As intensive cultivation and greenhouse planting become increasingly common, and as continuous cropping of ginseng and other economic crops increases, soil-borne continuous cropping diseases (such as root rot) are becoming more and more serious.

Soil-borne pathogens are one of the main causes of continuous cropping diseases (such as root rot) in crops. The pathogens mainly attack the stem base and roots of economic crops such as ginseng, cucurbits and vegetables. The usual incidence rate is 10-30%, and plants often wither and die, causing gaps in the rows and missing plants. In severe cases it can reach 80-90%, or even kill the entire field, resulting in total crop loss. It is a devastating disease. At present there is still no effective method of prevention and control, and it is a major problem in the cultivation of economic crops such as ginseng, cucurbits and vegetables.

For many years, researchers at Nankai University have studied the biological, chemical and physical properties of the soil of crops affected by continuous cropping diseases (such as root rot), accumulating a large amount of data and experimental results. Through repeated experiments and exploration, they have successfully developed a micro-ecological control agent whose main component is natural substances. These natural substances decompose under the action of active bacteria, and by means of microbial antagonism they enhance the growth and reproduction of antagonistic bacteria, which can effectively inhibit pathogenic bacteria, restore the balance of the soil micro-ecology, and promote the synthesis of enzymes in plants and the production of nutrients according to the growth needs of the crops, thereby achieving the effects of inhibiting bacteria, preventing disease, strengthening plants and increasing yield.
