对新疆向日葵白锈病进行调查、病原鉴定,结果表明侵染向日葵的病原菌为霜霉目白锈菌属(Albugotragopogonis(Pers.)S.F.Gray=Cystopustragopogonis(Pers.)J.Schrot)。病害发生与降雨和湿度关系密切,特别在高海拔、低温地区发生危害重。加强田间管理,合理密植,降低田间湿度,清除病残体;发病初期喷施58%甲霜灵WP500倍液、64%杀毒矾WP600倍、72%霜疫必克WP800倍液等药剂,可有效控制该病的发生。
The white rust of sunflower in Xinjiang was investigated and the pathogen was identified. The results showed that the pathogen of sunflower was Albugotragopogonis (Pers.) S.F. Gray = Cystopustragopogonis (Pers.) J. Schrot). Disease occurrence and rainfall and humidity are closely related, especially in the high altitude, low temperature damage occurred. Strengthen the field management, rational close planting, reduce the field humidity, remove the disabled; early onset of spray spraying 58% metalaxyl WP500 times, 64% anti-virus alum WP600 times, 72% Control the occurrence of the disease.
