Antidotal effects of OM against the herbicidal compounds, CD and CD related compounds were examined on their herbicidal activity changes. (1) Suceptibility of Gramineae and Polygonaceae to CD decreased by the addition of OM. On the contrary, those of broad leaf plants increased. Such phenomenal results were not dominated by plant leaf stage. (2) Antidotal action of OM on wheat injury by CD was diminished by simulated rainfall and high temperature condition. Reducing injury action of simultaneous treatment with CD and OM was more effective than the separate treatment with them. (3) OM action to wheat and barley injury by CD-analogues depended upon a chemical species of CD-analogues. It was necessary to choose a OM/CD-analogue mix ratio for the purpose of reducing injury by CD-analogue. Herbicidal activity of CD-analogues on mustard (Brassica juncea Coss.) increased by the addition of OM. (4) OM efficacy as antidote was presumed to be independent of characteristic component i. e., substituted β-diketones of epicuticular wax.
