- Abstract
Sulphonylureic herbicides are a group of post-emergent herbicides which contain in chemical structure sulphonylurea. Sulphonylureic herbicides have three distinct parts in their molecule: a nitrogen heterocycle, a sulphonylurea bridge and an aryl group. Tribenuron-methyl and nicosulfuron are part of this group of herbicides. They are commonly used in agricultural crops even though they cause qualitative and quantitative changes in soil microbial communities. The studies aimed to reveal the effect of these two herbicides applied under laboratory conditions on soil mold communities from soil. Potato-Glucose-Agar (PGA) medium was used to isolate the main genus of molds. The main genus of fungi isolated was represented by Fusarium, Mucor, Penicillium, Aspergillus, Curvularia, Cladosporium, Rhizopus si Humicola. Fusarium sp. is the main component of the experimental variants, demonstrating its strongest resistance to the xenobiotic actions. Sulfonylureic herbicides, tribenuron-methyl and nicosulfuron point out a lower value, inhibiting the actinomycetes community development and fungi communities in soil.
