摘 要:紫苏是延边地区的重要经济作物之一.但目前随着种植年限的延续,开始大量发生虫害、病害以及草害等,从而导致减产、降效,严重影响苏子生产.研究结果表明,延边紫苏地适宜土壤处理的除草剂为敌草胺与扑草净的混剂,使用剂量为3 kg/hm2+5 kg/hm2,一年生杂草除草效果可达到90%以上;茎叶处理除草剂为拿捕净(12.5%,1.0 kg/hm2)、稳杀得(35%,1.0 kg/hm2)、精禾草克(5%,1.0 kg/hm2);紫苏的主要病害为锈病,对紫苏叶片质量影响较大;主要食粒虫害(待定)对产量的影响较大.The Perilla frutescens (Linn.) Britt. is one major commercial crop in Yanbian area. With the continuation of planting years, lots of pests, diseases and weeds emerged which effected the output of Perilla frutescens (Linn . ) Britt. The research results showed that the fit herbicides of soil treatment for Perilla frutescens ( Linn . ) Britt. was the mixture of napropamide 3 kg/hm and prometryn 5 kg/hm whose controlling effect on the annual weeds could reach more than 90%. The fit herbicides treated to the stems and leaves of Perilla frutescens (Linn.) Britt. were sethoxydim (12.5%, 1.0 kg/hm2), fluazifop-butyl (35%, 1. 0 kg/hm2 ) and quizalofop-p-ethyl ( 5 % , 1.0 kg/hm2 ) . The main desease in Perilla frutescens ( Linn . ) Britt. was rust disease which effect the quality of Perilla frutescens (Linn. ) Britt. leaves seriously. The main insect pest (undetermined) had quite serious effect on the output of Perilla frutescens ( Linn . ) Britt. .
