Tracer incorporation studies and quantitative analysis showed that dichlorvos is a potent inhibitor of Zearalenone (F-2) biosynthesis by Fusarium roseum ‘Graminearum’. Dichlorvos also strongly inhibits production of perithecia by the fungus, and its inhibitory action can be reversed by F-2. This evidence suggests that F-2 may be a true fungal hormone which governs development of the sexual stage.
