Abstract: In order to research the inhibition effect on citrus pathogen with Chinese herbal extracts, Rhizoma ligustici Chuanxiong, Cortex acanthocephala Radicis, Radix angelicae Biseratae and other 6 Chinese herbals were used as materials for antibacterial liquid extraction, and the antibacterial effect on 3 kinds of cirtus pathogens (white mold, brown rot phytophthora and finger penicillium) were identified. The results showed that the extracting liquid of Chinese herbal had different inhibiting effects on different cirtus pathogen, and the inhibiting effects of Rhizoma ligustici Chuanxiong were the most obvious. When the extracting liquid density of Rhizoma ligustici Chuanxiong was below 1.0×10^-3 g/mL, it still had obvious inhibiting effects on 3 kinds of cirtus pathogens. The film preservation tests indicated that adding Rhizoma ligustici Chuanxiong of a density of 0.10% into chitosan membrane would have obvious enhanced effects on fresh citrus.
