摘要: 以‘郑单958’为试材,选用8种药剂,设置10个处理,进行田间试验。结果表明:种子包衣对玉米地下害虫和灰飞虱具有较好的防治效果。31%寡糖?噻?氟虫种子包衣+14%氯虫?高氯氟抽雄期喷施,玉米螟虫防效为90.35%~93.96%,蚜虫防效为91.82%~92.72%,均显著高于单独喷施。抽雄期喷施18.7%丙环?嘧菌酯、75%戊唑?嘧菌酯、75%肟菌?戊唑醇对玉米叶斑病、南方锈病具有较好的防治效果。抽雄期喷药,对小斑病、褐斑病、南方锈病的防效,18.7%丙环?嘧菌酯分别为83.36%、76.51%、78.93%;75%戊唑?嘧菌酯分别为79.25%、75.76%、83.81%;75%肟菌?戊唑醇分别为76.32%、82.83%、74.51%。不同药剂处理均比对照显著增产。31%寡糖?噻?氟虫+14%氯虫?高氯氟+75%戊唑?嘧菌酯比与对照增产21.77%,比31%寡糖?噻?氟虫+14%氯虫?高氯氟增产7.94%,比单独种子包衣增产13.83%,比单独喷洒14%氯虫?高氯氟增产13.45%,比单独喷洒18.7%丙环?嘧菌酯11.54%。因此,豫东平原夏玉米高产栽培,应采取种衣剂包衣和田间喷施杀虫防病农药相结合综合防控病虫害。

Abstract: Using "Zhengdan 958" as a test material, 8 kinds of chemicals were selected, and 10 treatments were set up to conduct field trials. The results showed that seed coating had good control effect on corn underground pests and Laodelphax striatellus. 31% oligosaccharide ? Thiofenil seed coating + 14% chlorantran ? high chlorofluorocarbon sputum spraying, corn mites control effect is 90.35%~93.96%, locust control effect is 91.82%~92.72%, both are significantly higher than Spray separately. Spraying 18.7% of acyclovir, azoxystrobin, 75% of pyrazole, azoxystrobin, and tebuconazole have good control effects on corn leaf spot and southern rust. In the tasseling period, the control effect on small spot disease, brown spot disease and southern rust was 18.3%, and the azoxystrobin was 83.36%, 76.51%, and 78.93%, respectively; 75% of the ethiazole and azoxystrobin were 79.25. %, 75.76%, 83.81%; 75% sputum and tebuconazole were 76.32%, 82.83%, and 74.51%, respectively. Different drug treatments significantly increased yield compared to
