TriCore PGP is a blend of bacteria and fungi that were selected from over 2000 different strains using an extensive screening process. The microbes create biofilms around root systems, interacting with the plant and allowing key nutrients that have been bound in the soil to be absorbed. This interaction also helps prevent plant pathogens from attacking the crops.

Represented in the photo of the corn plants below, a 2013 study conducted with Hefty Seed Company showed a yield increase of TriCore PGP vs. Control of 8 (175 vs 167 bushels/acre) bushels per acre in 48 replications with a p value of >.01 (or a 99% chance that the results can be replicated). The strains of bacteria in the product create healthier soils and crops. TriCore PGP is effective inoculant on soybeans, as well.

Some of the attributes of the strains in this product include:

Antagonistic activity -­‐ The production of compounds that kill or inhibit the growth of plant pathogens (specifically Rhizoctonia, Phytophthora, Fusarium, and Pythium).

Nutrient cycling -­‐ breaking down organic matter that is in the soil and making it available for plants.

Nutrient release -­‐ releasing nutrients that are chemically bound to the soil, specifically phosphorous and potassium. Nitrogen fixation -­‐ taking nitrogen (N2) from the air and making it available to the plant.

Phosphorus & potassium solubilization-­‐ organic acid production on the root system solubilizes phosphorus and potassium salts.

Plant growth promotion -­‐ the production of biochemicals that stimulate plant growth or greening.

Niche occupation -­‐ occupying the spaces on a root or leaf surface that are binding sites for pathogens. It is simply a blocking mechanism.

Induced Systemic Resistance (ISR) -­‐ bacteria that trigger the plants to produce disease-­‐controlling compounds. It has been shown that bacteria added to a root system can protect the leaves from disease using this mechanism.

Nutrient competition -­‐ Utilizing the root exudates so a pathogen cannot grow or even detect the presence of the root exudates.
