Popis:	Pesticides were added to soil at a rate of 10 mg/kg and then planted with corn, wheat, or bean seeds. Captan and thiram caused an initial decrease in the fungal populations but by 108 days the populations returned to levels found in untreated soils. The bacterial populations fluctuated inversely with the fungal populations. In soil planted with corn, atrazine had no effect on the microbial populations, however, in soil containing wheat and beans, populations of fungi and bacteria increased. Stimulation of the microbial populations in the atrazine-treated soils was attributed to the decay of the dead wheat and bean plants. Atrazine in combination with captan or thiram had neither synergistic nor antagonistic effects on the microbial populations.
