Currently, growers can choose from among nearly two-hundred microbe-containing crop biostimulants advertised to enhance yield and/or limit crop stress. That’s difficult. The production and sale of these products are largely unregulated (unlike biopesticides used in biocontrol). Also, research-based and grower-focused information on biostimulants is limited. People look for input and resources to help them select, use, and evaluate the efficacy of microbe-containing crop biostimulants when applied to field- or high-tunnel grown crops. Contact Matt Kleinhenz and watch for newsletter and other updates regarding various grower-university-product manufacturer efforts to provide that assistance.
