摘要
为积极探索玉米大、小斑病防治的有效方法,促进玉米稳产增产,文章采用田间试验的研究方法,在玉米4~6叶期和大喇叭口期各喷施1次质量分数为0.01%的芸苔素内酯可溶液剂+250 g/L吡唑醚菌酯乳油+质量分数为63%的非离子表面活性剂,结果表明,对玉米大、小斑病防效可达85.68%,且能够促进玉米营养生长,增加生物产量,增产率可达20.70%。
In order to actively explore the effective methods of controlling maize leaf spot and small leaf spot,and promote the stable yield and yield increase of maize,the field experiment method was adopted in this study.0.01%brassinolide solubilizer+250 was sprayed once at 4~6 leaf stage and big bell mouth stage respectively The results showed that the control effect of pyrazoxystrobin EC+63%non-ionic surfactant was 85.68%,and it could promote the nutritional growth of maize,increase the biological yield,and increase the yield by 20.70%.
