摘　　要：采用生长速率法研究了蓖麻籽粗提物对花生网斑病菌的抑制作用。结果表明:不同浓度的蓖麻籽粗提物对花生网斑病菌均有不同程度的抑制作用,且随着药剂浓度的增加,抑制率增大;但随着时间的推移,抑制效果逐渐减弱,24、48、96 h的EC50分别为218.3、367.27和438.78 mg/L。The growth rate method was adopted to study the effects of castor bean crude extracts on Pho- ma arachidicola. The results showed that different concentrations of castor bean crude extracts could inhibit Phoma arachidicola in different degrees. The inhibitory effect increased with the increase of concentrations, but decreased gradually with the prolonging of time. The ECs0 was 218.3, 367.27 and 438.78 mg/L respec- tively after treated for 24, 48 and 96 hours.
