General Observations: *The longer the wait to apply any fungicide after mycorrhizal fungi inoculation, the better for the mycorrhizal fungi development. **Most foliar sprays of any fungicide (except systemics such as Bayleton) have little effect on mycorrhizal fungi. This chart is updated periodically, as new products are added, and results of new trials are published.

  Mycorrhizal fungi (MF) are one of the most beneficial organisms on the planet. These fungi colonize plant roots, acting as root extenders to aid roots. MF are more efficient than roots and MF benefits are numerous. Increased root mass. Plants allocate a certain amount of energy to the root system. In the absence of MF, plants must build root hairs, which requires a lot of energy. Plants colonized with MF do not produce root hairs and instead use a much smaller amount of energy to allow MF to perform the job of absorbing water and nutrients. The hyphae (root-like structure) of MF is about 1/16th the diameter of a root hair (1/10 the diameter of human hair), and it takes about 1/256th the energy investment per mm of length to build than a root hair. With this energy savings, MF colonized plants tend to build much better root systems. Improved drought tolerance. One of the primary functions of a root system is water uptake and a colonized root will do so much better than an uncoloni...
