摘要
烟嘧磺隆是磺酰脲类玉米田专用除草剂,具有茎叶处理活性和一定的土壤封杀作用。自2000年起开始试验推广,累计推广1.33万hm2,根据生产需要2008年在甜玉米上再次进行了烟嘧磺隆单用及混用配方试验,总结出了烟嘧磺隆在玉米苗后除草技术规范:施药期宜在玉米5～8展叶,杂草3～5叶期进行;4%烟嘧磺隆单用60～80mL/667m2,混用60～70mL/667m2+38%阿特拉津100～150mL/667m2;施药时喷头适当压低或戴防护罩。
Nicosulfuron is dedicated corn sulfonylurea herbicides,with Postemergence activity and a certain role in the soil block.Since 2000,started experimenting with the promotion,the cumulative extension 13 300 hm2,according to production needs in 2008 again in the sweet corn had Nicosulfuron alone and mixed formula test,summed up nicosulfuron postemergence weed control technology in corn Specifications:spraying period of 5 to 8 should show in maize leaves,weeds 3 to 5 leaf stage carried out;4% nicosulfuron alone 60～80 mL/667 m2,mixing 60～70 mL/667 m2+38% Art Lazin 100～150 mL/667 m2 ;nozzles when spraying down or wear appropriate protective cover.
