Biostimulants: fact or fake news?

The use of biostimulants has increased throughout the turfgrass industry over the past decade. Technically, anything that has a positive impact on living organisms can be classified as a biostimulant, but that list would become too broad very quickly. Confusion still exists about commercial product ingredients, positive effects, and expected outcomes from the application of these materials. This presentation will attempt to define the differences between the terms biostimulant and biofertilizer with examples from each category. Not all products will result in beneficial outcomes for every turfgrass species within every turfgrass environment and under every management regime; therefore, this presentation will outline proper steps to test materials at your specific location.
