Prevention and Control of serious Diseases of Ginseng and other Economic crops

Root rot is one of the most serious diseases of ginseng and other cash crops. with the increasing intensity of planting and greenhouse planting and the increase of continuous cropping of cash crops such as ginseng, the disease of soil continuous cropping (root rot, etc.) is becoming more and more serious.

Soil pathogen is one of the main causes of crop continuous cropping diseases (root rot, etc.). The pathogen mainly harms the stem base and roots of cash crops such as ginseng, melons and vegetables. The general incidence rate is 10-30%, and plants often die, resulting in lack of seedlings and broken ridges. Serious up to 80% 90%, or even the whole garden death, resulting in no harvest, is a devastating disease. At present, there is no effective way to control the disease, which is a difficult problem in the cultivation of economic crops such as ginseng, melons, vegetables and so on.

For many years, researchers in Nankai University have accumulated a large number of data and experimental data in the study of biological, chemical and physical properties of crops with continuous cropping diseases (root rot, etc.). A microecological control agent with natural substances as the main component has been successfully developed. This natural substance is decomposed under the action of active bacteria, and the antagonistic action of microorganisms is used to enhance the growth and reproduction of antagonistic bacteria, which can effectively inhibit pathogenic bacteria and restore the balance of soil microecology. and can promote the synthesis of enzymes in plants, produce nutrients according to the needs of crop growth, so as to achieve the effect of bacteriostasis, disease prevention, healthy plants and yield increase.
