摘要
为探索玉米大斑病及主要虫害一体化防控效果,2018-2019年,在黑龙江省农业科学院齐齐哈尔分院试验基地对玉米大斑病及主要虫害一体化防控进行了田间试验。结果表明:在玉米大喇叭口期,大斑病刚要开始发生时期喷施,此时期也是玉米螟低龄幼虫及双斑萤叶甲成虫发生初盛期,18.7%丙环·嘧菌酯悬乳剂900 mL·hm^-2+5%氯虫苯甲酰胺悬浮剂600 mL·hm^-2对玉米大斑病的防治效果大于80%,对玉米螟的防治效果在85%以上,对双斑萤叶甲的防治效果在70%以上,防控前移,一喷多防,一体化防控玉米主要病虫害。
In order to explore the period and effect of integrated prevention and control on Northern maize leaf blight and main insect pests,field trials conducted in 2018-2019.The results showed that in the maize large bell period,spraying at the beginning of Northern maize leaf blight,this period was also the beginning of the occurrence of the young Ostrinia furnacalis larvae and Monolepta hieroglyphica adults.The control effect of azoxystrobin·propiconazole 18.7%SE 900 mL·hm^-2+Chlorantraniliprole 5%SC on Northern maize leaf blight was greater than 80%,the control effect on Ostrinia furnacalis was greater than 85%,the control effect on Monolepta hieroglyphica was greater than 70%,prevention and control move forward,one spray,multiple defense,integrated prevention and control on main maize diseases and insect pests.
