2-Thio, 2-sulfinyl and 2-sulfonyl pyridine N-oxides of the formula ##STR1## are useful for regulating the natural growth or development of plants. E.g., the compound wherein n = 1, R.sub.1 = methyl and R.sub.2 = 2,3,4-trimethylphenyl retards cotton and increases root growth of turf.
式为##STR1##的2-硫代、2-亚磺酰基和2-磺酰基吡啶N-氧化物对于调节植物的自然生长或发育非常有用。例如,当n = 1,R.sub.1 = 甲基和R.sub.2 = 2,3,4-三甲基苯基时,该化合物会减缓棉花的生长并增加草坪的根系生长。
