"Subsequent research on glyphosate interactions with soil microorganisms demonstrated that although glyphosate was metabolized by a segment of the microbial population, it was also toxic to several bacteria and fungi; the net effect glyphosate appeared to be a disruption of soil and root microbial community composition because selected components of the microbial community were stimulated while others were suppressed."<ref>Preface "Glyphosate interactions with physiology, nutrition, and diseases of plants: Threat to agricultural sustainability?", European Journal of Agronomy 31 (2009) 111-113.</ref><ref>Wardle, D.A., Parkinson, D.A., 1992.

Rahe, [http://www.annualreviews.org/doi/abs/10.1146/annurev.py.30.090192.003051 Herbicide Interactions with Fungal Root Pathogens, with Special Reference to Glyphosate], Annual Review of Phytopathology (1992), Vol. 30: 579-602.</ref> Levesque and Rahe (1992) showed evidence that herbicides can have a direct effect on various components of the soil microflora, such as plant pathogens, antagonists, or mycorrhizae, which can potentially increase or decrease the incidence of plant disease. Pathogens able to infect weeds can also increase their inoculum potential after weeds have been sprayed with herbicides, which could subsequently affect host crops."<ref>Fernandez</ref>
