1Trial conducted on the Western Colorado Research Center; seeded 6/12 and harvested 10/9. ²Myconate 7 is a new agricultural product developed by researchers at Michigan State University. Myconate7 is a signal compound put out by plant roots in times of stress that encourages beneficial fungus (mycorrhizae) to colonize them. The fungus extends the plants root system and helps it take up nutrients and water, and fight off disease. Previous research has shown significant yield increases on a number of crops in a variety of locations. This simple compound is non-toxic, is quickly broken down in the soil, and is effective in very small quantities. It is water soluble and easy to apply to seeds or soil. Myconate7 is a trademark product of VAMTech, L.L.C., commercially available for enhancing mycorrhizal colonization. ³Some yield variation resulted from herbicide damage in parts of the trial with sandy soil.
