摘要
通过田间试验方法,研究4种药剂对甜玉米叶斑病的防治效果.结果表明,凯润(250g/L吡唑醚菌酯乳油)、Opera(唑菌胺脂133g/L+氧唑菌50g/L)、欧宝(75g/L氟环唑乳油)、必扑尔(250g/L丙环唑乳油)4种药剂均对甜玉米大小叶斑病有良好防效;Opera750倍液、凯润1500倍液对甜玉米叶斑病的防治效果极显著优于必扑尔1000倍液、欧宝600倍液的防治效果,因此,大田甜玉米生产防治甜玉米叶斑病建议选用Opera750倍液或凯润1500倍液.
The field test method was adopted in this experiment, The control effects of 4 chemicals fungicides on sweet corn leaf spot were studied.The results show that Kairun（250g/L ovraclostrobin EC）, Opera（Azole fat 133g / L ＋ Epoxiconazole 50g/L）, Oubao（75g/L EPOXICONAZOLE EC） , Bipuer（250g/L Propiconazole EC）, The 4 chemicals fungicides had good control effect on the leaf spot of sweet corn. The control effect of Opera 750 times liquid or Kairun 1500 times liquid of sweet corn leaf spot disease was significantly superior to Bipuer 1000 times liquid or Oubao 600 times liquid. Consequently, it is suggested that Opera or Kairnn be used to prevent and control sweet corn leaf spot in field sweet corn production.
