  • COMPOSITION FOR PLANT DISEASE CONTROL COMPRISING LIMONENE DERIVATIVES AS ACTIVE INGREDIENTS
    Publication number: 20200205407
    Abstract: The present invention relates to a composition for controlling plant diseases containing a limonene derivative as an active ingredient. In the present invention, the limonene derivatives have an effect of inhibiting the growth of Xanthomonas oryzae pv. Oryzae (Xoo), which is a pathogen mediating bacterial leaf blight, and Magnaporthe oryzae, which is a pathogen mediating rice blast, and it was confirmed in an experiment with respect to inhibition using volatility (i.e., in a state not being in direct contact with Xoo or M. oryzae) that the limonene derivatives have a growth inhibitory effect. Accordingly, the limonene derivatives have an inhibitory effect against the growth of Xoo and thus they can be effectively used as a composition for controlling plant diseases.
