| 摘 要： | 采用室内离体平皿法和田间小区试验测定了植物源农用杀菌剂银泰 (有效成分 :4 -丁酰基苯酚 )对小麦纹枯病菌 Rhizoctonia cerealis生长的抑制作用和对该病害的防治效果。结果表明 ,20%银泰乳油在 0～ 100μg/mL范围内随着浓度提高对小麦纹枯病菌的抑制作用增强 ,其 EC50 和 EC95分别为 36.11和 97.66μg/L;EC95明显小于对照药剂井冈霉素的检测数值 (327.6 4μg/L )。20%银泰乳油 200、400和 800mg/L防治小麦纹枯病的效果分别为 85.8%、89.3%和 92.3% ,与对照药剂甲基硫菌灵 400mg/L的防效 (87.0% )相当。

| Abstract: | Inhibition of fungicide Yintai (The effect component is 4-butanoyl phenol) on the pathogen of Rhizoctonia cerealis and its disease control effect were tested respectively by means of growing rate method and field experiment. The results showed that 20% Yintai EC played a stronger inhibiting effect on Rhizoctonia cerealis when the concentration of Yintai EC increased from 0 to 100 μg/mL. Its EC50 and EC95 were 36.11 μg/L and 97.66 μg/L. Its EC95 was significantly lower than the EC95 value of Jinggangmycin （327.64 μg/L）. The field trial indicated that the control effect of 20% Yintai EC on the sharp eyespot of wheat were 85.8%, 89.3% and 92.3% when it was used at the concentration of 200, 400 and 800 mg/L, respectively. This control effect was as good as the treatment of 70% thiophanate-methyl WP（400 mg/L）. |
