在有机分子中,由于其手性结构的不同,会使整个分子与作用靶标的结合度有较大的差异。生物活性分子合适的空间结构对药效的发挥起着重要的作用。生物活性分子空间结构的合适性是不可预知的,需要大量的创造性劳动才能获知。
同R构型的羧酸酯类化合物相比,本发明以S构型为主的光活性羧酸酯类化合物具有意想不到的高除草活性,在一定剂量下可有效控制杂草。因此本发明的技术方案还包括通式(I)化合物用于控制杂草的用途。
本发明还包括以通式(I)化合物作为活性组分的除草组合物。该除草组合物中活性组分的重量百分含量为5-90%。该除草组合物中还包括可接受的载体。
本发明的除草组合物可以多种制剂的形式施用。通常将本发明的化合物溶解或分散于载体中配制成制剂以便作为除草剂使用时更易于分散。例如:这些化学制剂可被制成可湿性粉剂或乳油。因此,在这些组合物中,至少加入一种液体或固体载体,并且通常需要加入适当的表面活性剂。
本发明另外的实施方案为防治杂草的方法,该方法包括将除草有效量的本发明的除草组合物施于所述杂草或所述杂草生长的场所或其生长介质的表面上。通常选择的较为适宜有效量为每公顷1克到500克,优选有效量为每公顷2克到250克。对于某些应用,可在本发明的除草组合物中加入一种或多种其它的除草剂,由此可产生附加的优点和效果。
本发明的化合物既可以单独使用也可以和其它已知的杀虫剂、杀菌剂、植物生长调节剂或肥料等一起混合使用。
应明确的是,在本发明的权利要求所限定的范围内,可进行各种变换和改动。

生测实施例
实施例2: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/cm2,喷液量500L/hm2,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563在施用剂量为150g a.i./hm2对百日草、苘麻、狗尾草或稗草具有较好的防效,防效率为100%。
