摘　　要：杀菌剂的生物测定是进行新品种筛选及抗性监测的重要手段。杀菌剂的生物活性是药剂、病原、环境间相互作用的结果。药剂在植物体的吸附、穿透和代谢是影响其生物活性的重要因子。基于农药穿透生物学的基本原理,通过对杀菌剂的作用特点、病原菌入侵行为、杀菌剂作用方式、传导方式以及杀菌剂的应用环境的分析,指出杀菌剂的生测离不开靶标寄主的参与,生物测定方法应尽可能真实地反映药剂在应用实践中的行为学特点,才有可能准确地表征化合物的生物活性或抗药性变化程度。Fungicide bioassay is an import method for new variety selection and resistance monitoring.Biological activity of fungicide is a result of common interreaction among fungicide,pathogen and the environment.Fungicide adsorption,penetration and metabolism in plants are critical factors for biological activity.Based on pesticide penetration biology,fungicide action characteristics and model,pathogen inbreed behavior,transmitting and application environment were ana-lyzing,and the results indicated that fungicide bioassay can＇t be conducted without target plant,and only by reflecting practical behavior characteristics of pesticide application with bioassay precisely,can fungicide biological activity or resis-tance be discovered objectively.
