摘　　要：田间试验结果表明,30%甲霜·噁霉灵水剂对西兰花苗期基部猝倒病具有较好的防治效果,药效随着用药倍数的加大而上升,施药后16 d 30%甲霜·噁霉灵水剂1 500倍、2 000倍的校正防效分别达78.75%、73.33%,其中2 000倍的效果分别比对照药剂72.2%霜霉威盐酸盐水剂600倍、3%噻霉酮可湿性粉剂600倍高出3.12、24.64个百分点,且安全性好,因此可以在生产上加以推广应用。Field efficacy trials indicated that metalaxyl-hymexazol 30%AS had good effects on controlling broccoli damping-off. The disease preventing efficiency grew with the increases in dose, with the efficiencies up to 78.75% and 73.33%, respectively, 16 days after spraying （1 500×, 2 000×）. The controlling effect of metalaxyl-hymexazol 30% AS （2 000×） was higher than propamocarb hydrochloride 72.2% AS （600×） and benziothiazolinone 3% WP （600×） by 3.12% and 24.64%. More importantly, metalaxyl-hymexazol 30% AS was safe to humans. So its application can be widely developed and popularized.
