In the course of our search of new herbicides among amino acid related compounds, we discovered that CD possessed relatively strong post-emergence herbicidal activity against broadleaf weeds. In order to find out the excellent antidote in cereal species, notably wheat, which may not reduce the herbicidal effects of CD and CD related compounds, antidotal activities of amine compounds were examined. (1) 1,8-Diaminooctane (OM) and p,p'-diaminomethylbiphenyl (DABP) exhibited an excellent selective antidotal effect. However, DABP was not suitable because of resulting in a wheat malformation. (2) Antidote OM should be used in an amount of 1 mole and above per 1 mole of CD. A series of compounds replaced the hydorogen atoms of OM amino groups with other organic radicals were without effect. (3) Antidotal activity of even carbon numbered α,ω-diaminoalkanes (DA) was higher than that of odd numbered DA. Such phenomena were attributable to the characteristics of DA itself. (4) Primary amine and free base were essential for the antidotal effect.
