“…). Fusarium strains have shown a significant increase in dry mass mycelium when 1·0 and 1·5 mmol l −1 of glyphosate were added at Czapek medium (Krzysko‐Lupicka and Sudol ). Likewise, an increase in growth when growth media were amended with glyphosate has also been reported for Trichoderma harzianum , Streptomyces spp.…”

Aims: To evaluate the cultivable mycobiota from agricultural soils exposed to pesticides, the aflatoxigenic capacity of Aspergillus section Flavi strains and the effect of glyphosate on lag phase and growth rates of native nontoxigenic Aspergillus flavus under different water potential (MPa) conditions on soilbased medium. Methods and Results: Culturable mycobiota analysis from different agricultural soils was performed by the surface spread method. The effect of glyphosate (0-20 mmol l À1 ) on the growth of A. flavus strains was evaluated on a soil extract solid medium. Mycobiota analysis of crop soils showed the presence of twenty-one genera of filamentous fungi. Aspergillus flavus and Aspergillus niger aggregate strains were isolated from the three soil types. Ninety-two per cent of A. flavus strains were toxigenic. In vitro assay results showed that at À0Á70 MPa, a significant increase in growth rate in all strains was recorded at 5 and 20 mmol l À1 of glyphosate. At À2Á78 MPa, this parameter remained constant at all glyphosate concentrations, except in GM4 strain where an increase in growth rate was recorded with increasing pesticide concentrations. At À7Á06 MPa, a significant increase in growth rate has also been observed in GM 3 strain with 5 mmol l À1 and in GM 4 strain with 10 and 20 mmol l À1 . Conclusions: This study showed that the imperfecti fungi Aspergillus spp., Penicillium spp., Trichoderma spp., Cladosporium spp. and Paecilomyces spp. are isolated as prevalent groups in agricultural soil exposed to pesticides, and the capacity of nontoxigenic A. flavus strains to tolerate different glyphosate concentrations under different water potential (MPa) conditions. Significance and Impact of the Study: This manuscript makes a contribution to the knowledge of cultivable fungal populations from agricultural soils exposed to pesticides and the glyphosate tolerance of A. flavus strains.

“…Considering that this pesticide can be utilized as nutrient and also as energetic substrate by fungi (Krzysko‐Łupicka et al . , ; Krzysko‐Lupicka and Sudol ; Zabaloy et al . ), the stimulation of growth rate observed suggests that the glyphosate may be utilized mainly either as carbon or as energy source.…”

“…According to Franz et al (1997) the phosphate group in glyphosate readily adsorbs to clay, aluminium and iron oxides in soil. However Krzyśko-Łupicka and Sudoł (2008) have shown that glyphosate does not accumulate in soil, since microorganisms are able to breakdown C-P bonds, resulting in the release of inorganic phosphorus. Microbial degradation of glyphosate, and other herbicides, in soils there is a function of three key variables: the ability of the microorganisms to degrade the pesticides, the quantity of these microorganisms in the soil, and the activity of the soil microbial enzyme system (Sannino and Gianfreda 2001).…”

“…Glyphosate was reported to inhibit growth of mycorrhizal fungi and could favor the growth of less desirable fungal species, like soil-borne pathogens (Johal & Huber, 2009). Krzysko-Lupicka & Sudol (2008) observed a bias towards the selection of autochtonous Fusarium strains after treatment with the herbicide. This could be related with changes in microbial populations that alter the equilibrium and ultimately lead to diminishing biodiversity, as the postulated decrease in the (pseudomonad) antagonists of fungal pathogens observed by Kremer & Means (2009) in long-term field studies.…”
