Molecular size and hydrophobic property (log P) of α,ω-diaminoalkanes (DA) in connection with antidotal action of OM and chemical structure of cutin were considered in some detail. A speculative mechanism of antidotal action by OM for herbicides was postulated from the above described consideration. ( 1 ) The reduction of CD injury to wheat was little under the condition of OM dissolved into Hogland nutrient solution. Similarly, diuron injury to cotton was not reduced by OM under the above mentioned treatment. ( 2 ) It was presumed that a good relationship between the antidotal action to CD-injury to wheat and cold injury of radish by the foliar-applied DA and molecular size as well as log P of DA. ( 3 ) From a consideration about chemical structure, component and biosynthetic pathway of cutin, it was thought that, probably, cutin bears a fair number of space apertures corresponding to the distance of octamethylene unit. Therefore, it seems likely that the OM wedges inserted into space openings result in antidotal effect.
