摘要
为筛选防治小麦赤霉病的高效药剂,对25%氰烯菌酯SC、42%咪鲜·甲硫灵WP、50%咪鲜胺WP、400 g/L戊唑·咪鲜胺EW和25%多·酮WP进行筛选试验。试验证明:25%氰烯菌酯SC、42%咪鲜·甲硫灵WP和25%多·酮WP对小麦赤霉病的防治效果较好,其用药适期为小麦齐穗扬花期,最佳用药量为25%氰烯菌酯SC 1500 mL/hm2、42%咪鲜·甲硫灵WP 1200 g/hm2和25%多·酮WP 1800 g/hm2,最终防治效果均在85%以上。
In order to screen effective fungicides for controlling wheat scab,the field tests were carried out using five fungicides such as JS399-19 25% SC,prochloraz ＋ thiophanate-methyl 42% WP,etc.The results showed that JS399-19 25%SC 1 500 mL/hm^2,prochloraz ＋ thiophanate-methyl 42% WP 1 200 g/hm^2and carbendazim ＋ triadimefon 25% WP 1 800 g/hm^2could control wheat scab effectively,the control effects were all above 85%.The optimal use time was wheat flowering stage.
