| 摘 要： | 采用菌丝生长速率法测定了40%嘧霉胺可湿性粉剂和50%异菌脲可湿性粉剂对番茄灰霉病菌的室内毒力,并对其抗番茄灰霉病作用进行了连续2 a的田间药效评价。结果表明:嘧霉胺和异菌脲对番茄灰霉病菌的EC50值分别为5.43和8.73 mg/L;当分别以1 170和1 125 g/hm2浓度处理番茄植株时,40%嘧霉胺可湿性粉剂和50%异菌脲可湿性粉剂对番茄灰霉病的防治效果均可达到74%以上,明显高于对照药剂75%百菌清可湿性粉剂1 800 g/hm2的防效。

| Abstract: | The toxicity of pyrimethanil 40% WP and iprodione 50% WP against Botrytis cinerea Pers were measured by investigating growth velocity in PDA culture media.Meanwhile,the efficacy of this two fungicides against grey mould of tomato was tested in the field in 2006 and 2007.The result showed that the EC50 of pyrimethanil and iprodione were 5.43 and 8.73 mg/L,respectively.The control effects of the tested fungicides were all above 74% and obviously higher than the control fungicide,chlorothalonil 75% WP,when the treatment concentrations were 1 170,1 125 and 1800 g/hm2,respectively. |
