Effective Microbes provides beneficial bacteria and fungi in a stable form for nutrients, to feed them once they get into the environment. By dramatically increasing native microbe populations and in turn, their beneficial activity, it alleviates plant stress. It acts as a probiotic inoculant, colonizing both fruit and branches with microbes to promote fruit growth and disease resistance. Effective Microbes is an AgriGroÂ® product, marketed under the name Ignite S2. At this time we consider it the most stable, storable and reliable product to effectively increase microbial activity.
