The invention provides a method of regulating the growth of a plant using a compound of the formula:
wherein R¹ represents alkyl or phenyl optionally substituted by halogen, alkyl, alkoxy, alkylthio, trifluoromethyl, trifluoromethoxy, trifluoromethylthio, nitro, cyano, amino, carboxy, phenoxy, benzyloxy, alkoxycarbonyl, alkylamino, dialkylamino, alkanoylamino, R² represents nitro, cyano, carbamoyl or -CONR⁵R⁶ or -NR⁶COR⁵ (wherein R⁵ is as hereinbefore defined for R¹ and R⁶ represents hydrogen or alkyl), R³ represents halogen, nitro, cyano, amino, carbamoyl, -CONR⁷R⁸ (wherein R⁷ is as hereinbefore defined for R¹ and R⁸ represents hydrogen or alkyl), and R⁴ represents hydrogen or alkyl, or salts thereof with the exclusion of compounds in which R² and R³ simultaneously represent cyano groups; plant-growth regulating compositions, novel compounds and their preparation are described.
该发明提供了一种利用以下化合物调节植物生长的方法:其中R¹代表烷基或苯基,可选择地取代为卤素、烷基氧基、烷基硫氧基、三氟甲基、三氟甲氧基、三氟甲基硫氧基、硝基、氰基、氨基、羧基、苯氧基、苄氧基、烷氧羰基、烷基氨基、二烷基氨基、烷酰氨基,R²代表硝基、氰基、氨基甲酰基或-CONR⁵R⁶或-NR⁶COR⁵(其中R⁵如前述定义的R¹,R⁶代表氢或烷基),R³代表卤素、硝基、氰基、氨基、氨基甲酰基、-CONR⁷R⁸(其中R⁷如前述定义的R¹,R⁸代表氢或烷基),R⁴代表氢或烷基,或其盐,排除R²和R³同时表示氰基团的化合物;描述了植物生长调节组合物、新化合物及其制备方法。
