大葱病毒病药剂筛选试验

Screening Test for Anti-virus Agents in Green Chinese Onion

为寻找防治大葱病毒病的有效药剂,采用病毒必克二号、植病灵、东旺毒消和病毒清进行了田间药效筛选试验。结果表明:病毒必克二号和植病灵对大葱病毒病的预防效果较好,东旺毒消的预防效果次之,病毒清对大葱病毒病的预防效果较差。在大葱生产上选择病毒必克二号与植病灵搭配使用可取得较好的防治效果。

To select effective agent for onion yellow dwarf viruse,bilken virusicide No.2,dodecyl sodium sulphate,24% mixed alphotic acid copper EC from Dongwang Company,and 20% moroxydine were applied for the screening test.The results showed that bilken virusicide No.2 and dodecyl sodium sulphate were effective for onion yellow dwarf viruse,the following was 24% mixed alphotic acid copper EC,and 20% moroxydine was not effective to the virus.Therefore,the combination of bilken virusicide No.2 and dodecyl sodium sulphate could be more effective in the green onion production.
