This invention relates to a method for regulating the growth of crop plants by applying to the foliage, roots, stems, seeds or to soil in which the crop plants are grown, an effective plant growth regulating amount of an imidazolinyl benzamide having the structure: ##STR1## wherein R.sub.1 is alkyl C.sub.1 -C.sub.4 ; R.sub.2 is alkyl C.sub.1 -C.sub.6, cycloalkyl C.sub.3 -C.sub.6, alkenyl C.sub.2 -C.sub.4, phenyl, halophenyl or benzyl; and when R.sub.1 and R.sub.2 are taken together with the carbon to which they are attached they may form cycloalkyl C.sub.3 -C.sub.6 optionally substituted with methyl; R.sub.3 and R.sub.4 each individually represent hydrogen, alkyl C.sub.1 -C.sub.4, alkenyl C.sub.3 -C.sub.5, alkynyl C.sub.3 -C.sub.5, or benzyl; and when R.sub.1 and R.sub.2 represent different substituents, the optical isomers thereof.
本发明涉及一种通过向农作物植物的叶片、根、茎、种子或种植农作物的土壤中施加有效的植物生长调节剂量的咪唑啉基苯甲酰胺来调节农作物植物生长的方法,该咪唑啉基苯甲酰胺具有以下结构:##STR1## 其中R.sub.1是烷基C.sub.1-C.sub.4;R.sub.2是烷基C.sub.1-C.sub.6、环烷基C.sub.3-C.sub.6、烯基C.sub.2-C.sub.4、苯基、卤代苯基或苄基;当R.sub.1和R.sub.2与它们附加的碳一起时,它们可以形成环烷基C.sub.3-C.sub.6,该环烷基可以选择性地被甲基取代;R.sub.3和R.sub.4各自独立地表示氢、烷基C.sub.1-C.sub.4、烯基C.sub.3-C.sub.5、炔基C.sub.3-C.sub.5或苄基;当R.sub.1和R.sub.2表示不同的取代基时,它们的光学异构体也包括在内。
