The invention relates to novel pyridazinylcarboxylic acid derivatives of the formula ##STR1## wherein R.sub.1 is hydrogen, a cation or C.sub.1 -C.sub.6 alkyl, Y and Y' are each independently an oxygen or a sulfur atom or a sulfinyl or sulfonyl group, R.sub.2 and R.sub.3 are each independently a C.sub.1 -C.sub.12 alkyl or C.sub.1 -C.sub.12 alkenyl group which is substituted by one or more halogen atoms, R.sub.4 and R.sub.5 are each independently hydrogen, halogen, nitro, cyano, C.sub.1 -C.sub.6 alkoxy, or C.sub.1 -C.sub.6 alkyl which is unsubstituted or substituted by one or more halogen atoms, and n is 0 or 1. These compounds have gametocidal properties and can be used for influencing generative plant growth and for producing male-sterile plants.
该发明涉及以下结构的新型吡啶并嗪羧酸衍生物:其中R.sub.1为氢、阳离子或C.sub.1-C.sub.6烷基,Y和Y'分别独立为氧或硫原子或亚砜基或磺酰基,R.sub.2和R.sub.3分别独立为一个或多个卤素原子取代的C.sub.1-C.sub.12烷基或C.sub.1-C.sub.12烯基基团,R.sub.4和R.sub.5分别独立为氢、卤素、硝基、氰基、C.sub.1-C.sub.6烷氧基或未取代或一个或多个卤素原子取代的C.sub.1-C.sub.6烷基,n为0或1。这些化合物具有杀配子作用,并可用于影响植物的生殖生长并生产雄性不育植物。
