Pollen is suppressed in dicotyledons by use of compounds of the formula
wherein X represents a group of the formula OR¹ wherein R¹ represents a C₁-C₄ alkyl optionally substituted with a C₁-C₄ alkoxy group or a C₂-C₄ alkenyl group; R represents phenyl or phenyl substituted with one to three halogen atoms or C₁₋₄ haloalkoxy or an agriculturally acceptable salt thereof, are disclosed along with methods to produce hybrid seed in self-fertilizing plants.
通过使用公式中X代表的化合物,其中X代表公式OR¹的一个基团,其中R¹代表一个C₁-C₄烷基,可选地被C₁-C₄烷氧基或C₂-C₄烯基取代;R代表苯基或被一到三个卤素原子或C₁₋₄卤代烷氧基取代的苯基,或其在农业上可接受的盐,使双子叶植物中的花粉被抑制。同时还公开了在自交植物中生产杂交种子的方法。
