Abstract:: Urtica fissa E.Pritz.，Datura stramonium Linn., Coriaria nepalensis Wall.and Phytolacca acinosa Roxb.were used as test materials，the antibacterial activity of four plant extracts against Pantoea agglomerans were tested by the method of bacteriostatic circle.The results showed that the growth of Pantoea agglomerans was obviously inhibited by biological pesticides.Such four poisonous plants could be candidates for the prevention and treatment of the associated pathogens causing blight on walnut.Coriaria nepalensis Wall.had the best inhibition effect and its inhibition rate was 44%.
