Abstract:

Root knot nematodes have a wide host range, spread rapidly, and difficult to control, posing a serious threat to the cultivation of Codonopsis pilosula. It is urgent to establish an efficient comprehensive control system. This study reviews the current harm status and latest research progress in prevention and control techniques of root knot nematode disease in Codonopsis pilosula, with a focus on the application of agricultural, physical, chemical, and biological pest control methods in agricultural production. The review found that agricultural control is the key to effectively implementing other control measures in the prevention and control of root knot nematodes, chemical control is the main measure, and biological control is gradually becoming a widely used control method. A comprehensive prevention and control scheme for root knot nematode disease of Codonopsis pilosula was proposed. The scheme includes: (1) implementing a scientific farming system and a reasonable crop rotation pattern; (2) breeding and promoting disease resistant varieties; (3) apply chemical pesticides accurately and efficiently; (4) cooperate with the application of effective biological agents. This scheme can provide reference for the prevention and control of root knot nematode disease.
