Carbon monoxide does not poison plants since it is rapidly oxidized to form carbon dioxide which is used for photosynthesis. Carbon monoxide rapidly oxidizes to form carbon dioxide. Especially at higher temperatures, it reacts explosively with numerous substances (e.g. aluminium dust, potassium, nitrogen dioxide) with heat being produced (e.g. bromine trifluoride, silver oxide). read more
