摘要
为了明确种菌唑·甲霜灵FSC对高粱的安全性及对高粱丝黑穗病的防治效果,通过盆栽试验、田间防治药效试验进行验证。试验结果表明,4.23%种菌唑·甲霜灵FSC提高出苗率,比空白对照高4%以上。利于苗期根系发育,根数、根长与空白对照相比差异显著;田间对高粱丝黑穗病有较高防效,其防效幅度为72.0%~82.0%,比空白对照增产6.8%~10.2%。综合比较,4.23%种菌唑·甲霜灵FSC可用于高粱防治丝黑穗病,适宜剂量为药剂与种子的比例为400 mL/100 kg。
In order to determine the safety to sorghum and control effect on head smut of Ipconazole·Metalaxyl FSC(I·M FSC), it was verified by pot experiment and field control efficacy test. The results showed that the 4.23% I·MFSC increased the emergence rate by more than 4% compared with CK. It is beneficial to the root development atseedling stage, and the root number and root length are significantly different from CK. The control effect of sorghumhead smut in the field was 72.0%-82.0%, which was 6.8%-10.2% higher than CK. Through comprehensive com-parison, 4.23% I·M FSC can be used to control sorghum head smut, and the appropriate dosage is the ratio of medi-cament to seed of 400 m L/100 kg.
