摘　　要：SIOC0163是嘧啶氧基芳基苄胺类玉米田除草活性化合物。室内生物活性测定结果表明,SIOC0163具有良好的芽后早期除草活性,能有效防除玉米田禾本科和阔叶杂草,对莎草科杂草也有良好的防效,使用适期为杂草1～3叶期、玉米4～7叶期,后茬作物小麦、油菜的ED10值分别为0.0034、0.0029 mg/kg。田间结果表明,当SIOC0163的有效成分为90～150 g/hm2时,其对玉米田主要杂草的总防效为75%～80%。SIOC0163 is a selectivity novel herbicidal compound of pyrimidinyl phenzylamine for post-emergence control of broadleaf and grass weeds in maize. The bioassay results showed that SIOC0163 had good activity to weeds for early post-emergence, and good safety to the maize seedling. SIOC0163 could control important grass and broad-leaved weeds, as well as sedge weeds in maize. The most suitable application date of SIOC0163 was 1 to 3 leaf-age weeds and beyond 4 leaf-age maize. The ED10 values of succeeding crops of rape and wheat were 0.0034 and 0.0029 mg/kg, respectively. The field results in maize showed good efficiency to the total weeds at 90-150 g/hm2.
