Title: Changes in soil microflora in response to repeated applications of some pesticides
Abstract: The effects of pesticides on soil microflora were studied on arable soils that had received repeated applications of carbofuran and carbosulfan (insecticides), iprodione and vinclozolin (fungicides), and MCPA, simazine and paraquat (herbicides). Carbofuran at single and 5-fold treatments did not show any detectable detrimental effects on soil microbial biomass, but single application of carbosulfan produced a significant biomass reduction. There were dramatic reductions in soil microbial biomass following vinclozolin application, and this was due to a reduction in fungal biomass; iprodione showed less obvious biomass trends. MCPA and simazine caused no detectable effects to the microflora, but repeated paraquat application significantly lowered soil microbial biomass (chiefly fungal biomass). The results indicate that there may be substantially different effects on soil biomass produced by single or repeated applications of pesticides.
