丙炔氟草胺是一种以原卟啉原氧化酶为作用标靶的N-苯基肽酰亚胺类除草剂。为探究其在棉花田的应用前景,山东农业大学植物保护学院研究人员通过温室盆栽法对丙炔氟草胺的杀草谱、除草活性及其对棉花的安全性进行了测定。结果表明:丙炔氟草胺对棉田常见阔叶杂草有较好防效,处理剂量为有效成分15g/hm~2时,对马齿苋、反枝苋、藜、小藜和鳢肠的鲜重防 Propargyl fluoride is an N-phenyl-peptide imide herbicide that targets protoporphyrinogen oxidase. In order to explore its application prospect in cotton field, the researchers at Plant Protection College of Shandong Agricultural University determined the herbicide activity and herbicidal activity against alkythronil and its safety to cotton by greenhouse pot experiment. The results showed that propoxurone was effective against common broadleaf weeds in cotton field. When the treatment dose was 15g / hm ~ 2, the effects of fluroxine, Fresh weight prevention
