生测实例
实施例5、除草活性的测定
将阔叶杂草(百日草、苘麻)或禾本科杂草(狗尾草、稗草)种子分别播于直径为7cm的装有营养土的纸杯中，播后覆土1cm，镇压、淋水后在温室按常规方法培养，待杂草2-3叶期后茎叶喷雾处理。
原药用丙酮溶解后，按试验要求用1‰的吐温80静置自来水配制所需浓度的待测液。按试验设计剂量，在履带式作物喷雾机(英国Engineer Research Ltd.设计生产)上进行喷雾处理(喷雾压力1.95kg/cm 2，喷液量500L/hm 2，履带速度1.48km/h)。试验设3次重复。试材处理后置于操作大厅，待药液自然阴干后，放于温室内按常规方法管理，观察并记录杂草对药剂的反应情况，处理后定期目测供试药剂对杂草的防除效果，用0～100％来表示，以“0”代表无防效和“100％”代表完全杀死。
试验结果表明，通式I化合物对多种杂草普遍具有较高防效。部分供试的化合物中，如化合物1-1、1-10、1-17、1-18、1-20、1-26、1-27、1-30、1-31、1-32、1-33、1-34、1-36、1-37、1-38、1-39、1-44、1-48、1-53、1-55、1-60、1-65、1-66、1-67、1-74、1-76、1-82、1-83、1-88、1-93、1-95、1-100、1-102、1-139、1-140、 1-167、1-168、1-173、1-178、1-179、1-181、1-187、1-193、1-198、1-200和1-205在施用剂量为600g a.i./hm 2时对百日草、苘麻、狗尾草或稗草具有较好的防效，防效大于等于90％。
按照以上测试方法，选取部分通式I化合物与KC1和KC2进行防除狗尾草的活性试验，结果见表2。
