摘　　要：向日葵白锈病和黑茎病是危害严重的新入侵病害,探索在种植中针对2种病害的防治措施是生产中急待解决的问题。为此,2015年在新疆新源县向日葵白锈病和黑茎病发生地进行了覆膜加药剂处理试验。试验结果表明:使用2.5%咯菌腈FS拌种+覆膜+2遍茎叶喷雾(第1遍茎叶喷雾22.5%杜邦阿砣SC150m L/hm^2+64%杀毒矾WP150m L/hm^2,对水225L/hm^2;第2遍茎叶喷雾70%甲基托布津WP300m L/hm^2+64%杀毒矾WP150m L/hm^2,对水225L/hm^2),对向日葵白锈病、黑茎病防效最好,向日葵产量也较高。该方法是生产中种植向日葵采取的有效措施之一。White rust and black stem disease in sunflower are two kinds of new invaded quarantine diseases. Aimed at exploration of the production problems for planting and prevention measures of two diseases, filming plus cryoprotectants were tested to investigate the occurrence of two diseases in 2015 of Xinyuan country, Xinjiang. The results showed that the treatment of 2.5% fludioxonil seed FS＋film＋2 times of stem and leaf spray（The first spray on stem and leaf： 22.5% Dubangatuo SC150 m L/hm^2＋64% Shadufan WP150 m L/hm^2, add water 225L/hm^2; The second spray on stem and leaf： 70% thiophanate methyl WP300 m L/hm^2＋64% Shadufan WP150 m L/hm^2, add water 225L/hm^2）acquired the best control effect and a higher yield.This method is one of the measures used in the production of planting sunflower.
