Trichoderma is a fungus that is common in the environment. You’ve probably seen it causing green mold on decomposing wood or bark. Some strains of this fungus have been formulated into products that are used for suppression of plant diseases and for growth enhancement. WSU is doing research into the uses of Trichoderma in nursery production. Please take this short survey and let us know what you think about Trichoderma.
