A mode of herbicidal activity of methoxyphenone including selectivity and chlorosis induction was studied. For the elucidation of selective herbicidal action between rice plant (tolerant) and barnyardgrass (susceptible), differences in absorption, translocation and metabolism of methoxy-phenone applied to the leaves, roots and seeds of the two plants were compared with the value of selective index estimated from chlorosis induction. The diffrences in absorption and translocation of methoxyphenone from the roots and seeds are evidently the dominant factors to cause the selective effect on both plants. No inhibitory effect of methoxyphenone on Hill reaction was observed. Slight inhibition was observed in respiration and RNA synthesis, but protein synthesis was not inhibited at all. Methoxyphenone inhibited the accumulation of chlorophyll and carotenoid in barnyard millet seedlings under strong light to yield white seedlings. Chlorophyll was accumulated in the treated seedlings grown under weak light but was destroyed in seedlings exposed to strong light. Carotenoid synthesis was inhibited in darkness as well as in the light and caused the accumulation of carotenoid precursors, phytofluene and ζ-carotene. Seedlings exposed to strong light lacked normal chloroplast structure. The disruption of the chloroplasts and loss of chlorophyll was supposed to be due to the absence of carotenoids in the treated plants, which would normally act to protect the chloroplasts and chlorophylls from photodestruction.
