Applied studies of biological control techniques on healthful Chinese crude drugs / 中国中药杂志

ABSTRACT

Medicinal plants always suffer from diseases and pests in their cultivation and growing, and the yield and quality are reduced. At present, chemical pesticide is mainly used to control the diseases and pests. The long-term use and over-use of pesticide result in pesticide residue, pests resistance to pesticide, water and soil pollution and other environmental contamination. It is necrssary to provide the integrated pests management, including new technology of biological control for developing green drug. This project makes research on the following aspects: 1. Applied studies on bethyloid wasp (Scleroderma guani) control for stem borer; 2. To develop Trichoderma spp. and use it to control the diseases of medicinal plants; 3. Applying Agro-antibiotics 120 to control phytophthora root rot of ginseng; 4. Researches on application of entomopathogenic nematodes against ten-spotted lema (Lema decempuntata) et al.
