Abstract

The effect of the fungicide diniconazole on the growth and volatile terpene content of garden sage and scotch spearmint was tested. The growth of both plant species was stunted, and the degree of stunting was dose dependent. Monoterpene levels on a per leaf basis were increased at all dosages in the case of sage, whereas in scotch spearmint lower dosages increased monoterpene levels, but higher dosages or repeated applications reduced them. Monoterpene composition was also altered by diniconazole treatment of sage. The results suggest that monoterpene biosynthesis was influenced either at the cyclization step of monoterpene formation and/or at a stage prior to the committed cyclization of geranyl pyrophosphate. The cytochrome P450-dependent hydroxylation of cyclic monoterpene olefins was not influenced by diniconazole.
