A method of combating undesired plant growth at a locus is disclosed, the method comprising applying to the locus a compound of general formula:
where R¹ and R² independently represent a hydrogen atom or an optionally substituted alkyl or alkenyl group or R¹ and R² together represent an optionally substituted alkyl or alkenyl chain;
R³ represents an optionally substituted saturated or unsaturated homocyclic or heterocyclic group;
and Z represents a group -COOR⁴ where R⁴ represents a hydrogen atom, a cation or an optionally substituted alkyl, alkenyl, alkynyl or aryl group, or Z represents a group -CHO.
The use of a compound of general formula I as a herbicide and a herbicidal composition are also disclosed.
本发明公开了一种在基因座上抑制植物不良生长的方法,该方法包括向基因座施用通式化合物:
其中 R¹ 和 R² 分别代表氢原子或任选取代的烷基或烯基,或 R¹ 和 R² 共同代表任选取代的烷基或烯基链;
R³ 代表任选取代的饱和或不饱和同环或杂环基团;
和 Z 代表基团-COOR⁴,其中 R⁴ 代表氢原子、阳离子或任选取代的烷基、烯基、炔基或芳基,或 Z 代表基团-CHO。
还公开了通式 I 的化合物作为除草剂和除草组合物的用途。
