Antiviral composition and method for controlling plant viruses using the same

Abstract

Disclosed are an antiviral composition, a composition for controlling plant viruses, and a method for controlling plant viruses using the composition. Trichodermin or Trichoderminol which is a tricothecene-based compound and is isolated from Trichoderma albolutescenes strain has antiviral activities against various plant viruses and is thus suitable for controlling plant viruses. This description can facilitate mass production of an active component derived from natural products, provide environment-friendly antifungal agents, which do not harm plants, using safe materials, and be variously utilized in agricultural fields, for example, such as production of high-value crops.
