Abstract

A method for controlling plant viruses comprising treating plant or soil with a composition for controlling plant viruses comprising Trichodermin wherein the composition has antiviral activity against plant viruses when applied to a plant or to soil. In some embodiments, the Trichodermin is isolated from a Trichoderma albolutescens strain.

First claim

What is claimed is:

1 . A method for controlling plant viruses comprising treating plant or soil with a composition for controlling plant viruses comprising Trichodermin represented by the following Formula 1:

wherein the composition has antiviral activity against plant viruses when applied
to a plant or to soil.

2 . The method of claim 1 , wherein the Trichodermin is isolated from a Trichoderma albolutescens strain.

3 . The method of claim 2 , wherein the Trichoderma albolutescens strain is Trichoderma albolutescenes KUC2115 strain, Deposit No. KACC93215P.

4 . The method according to claim 1 , wherein the plant virus is at least one selected from the group consisting of a tobacco mosaic virus (TMV), a pepper mottle virus (PepMoV), a cucumber mosaic virus (CMV), a pepper mild mottle virus (PMMoV), a zucchini yellow mosaic virus (ZYMV), a watermelon mosaic virus (WMV), a watermelon mosaic virus2 (WMV2), a potato virus Y(PVY), a turnip mosaic virus (TuMV), a melon necrotic spot carmovirus (MNSV), a cucumber green mottle mosaic virus (CGMMV), a zucchini green mottle mosaic virus (ZGMMV), a potato leafroll virus (PLRV), a lily mottle virus (LMoV), a lily symptomless virus (LSV), an odontoglossum ringspot virus (ORSV), a cymbidium mosaic virus (CyMV), a broad bean wilt virus (BBWV), a tomato ringspot virus (TomRSV), a tobacco ringspot virus (TRSV), a tomato spotted wilt virus (TSWV), a strawberry mottle virus (SMoV) and a cactus X virus (CVX).

5 . The method of claim 1 , wherein the composition is formulated into at least one selected from the group consisting of solutions, granules, powders, emulsions, oil solutions, wettable powders and pastes.

6 . The method of claim 1 , wherein the composition comprises a microbial cell or a culture medium of Trichoderma albolutescenes , or a mixture thereof.

7 . The method according to claim 6 , wherein the microbial cell or a culture medium of Trichoderma albolutescenes comprises Trichoderma albolutescenes KUC2115 strain, Deposit No. KACC93215P.

8 . The method of claim 1 , wherein a concentration of the Trichodermin in the composition is 5 ppm or above.
