碘苯腈系由May&Baker公司早在1963年即已开发,但近年来,辛酰碘苯腈却得以广泛应用。辛酰碘苯腈系能被植物茎叶迅速吸收,并通过抑制植物的电子传递、光合作用及呼吸作用而呈现其杀草活性。由于本剂在植物体其他部位无渗透作用,故宜于在杂草幼期使用,对于再生能力大 Iodobenzonitrile was developed by May & Baker as early as 1963, but in recent years, octanoyl iodide has been widely used. Octanoyl iodo-benzonitrile is rapidly absorbed by plant stems and leaves, and exhibits herbicidal activity by inhibiting the electron transfer, photosynthesis and respiration of plants. As the agent in other parts of the plant without infiltration, it should be used in young weeds, for large regeneration capacity
