Abstract:
The invention relates to a novel fungal protein which is effective for inducing or stimulating the defense responses of plants against disease. This protein, which is also referred to as an elicitor protein, may be used for the treatment or prevention of fungal infections in plants. The protein is produced by culture of Trichoderma virens (formerly known as Gliocladium virens), and may be subsequently recovered from the culture medium and purified. Crude or purified protein may be applied as a seed coating, or into furrows with the seed during planting. It has been used as an effective biocontrol agent of several soilborne root or seedling diseases. The protein is a natural product; therefore, it is of less environmental concern than synthetic pesticides. It could be used commercially in combination with pesticides that are currently in use, in an IPM strategey, or alone for seedling disease control. It could also be used in organic farming and gardening.
