摘要：The effect of linuron,alachlor and fomesafen on cellulolytics microorganisms was examined.A trial was set up in the laboratory on two soil types: vertisol and alluvium.Linuron was applied in concentrations of 0.5 and 1.0 mg a.i./1000 g air-dry soil.Alachlor was applied in concentrations of 1.2 and 2.4 mg a.i./1000 g and fomesafen was applied in concentrations of 0.1 and 0.2 mg a.i./1000 g soil.Sampling for microbiological analysis was done 1,3,7,14,30 and 60 days after herbicides application.The results show that the effect of linuron,alahlor and fomesafen on cellulolytics microorganisms depended on the duration of activity,rates of application and type of soil.During the initial 24h after herbicides application,no change was observed in the abundance in this microorganism group.Linuron demonstrated its activity from the seventh day,while fomesafen demonstrated inhibition on abundance cellulolytics microorgamisms third day after application.Liniron was stronger inhibitor than alachlor and fomesafen on both soil type.
其他摘要：U radu je ispitivano delovanje linurona,alahlora i fomesafena na celulolitske mikroorganizme zemljišta.Ogled je postavljen u laboratorijskim uslovima na dva tipa zemljišta: smonici i aluvijumu.Linuron je primenjen u količinama 0.5 i 1.0 mg a.m./1000g vazdušno suvog zemljišta.Alahlor je primenjen u količinama 1.2 i 2.4 mg a.m./1000g,a fomesafen u količinama 0.1 i 0.2 mg a.m./1000g.Uzorci za mikrobiološke analize uzimani su 1,3,7,14,30 i 60 dana posle primene herbicida.Dobijeni rezultati su pokazali da delovanje linurona,alahlora i fomesafena na celulolitske mikroorganizme zavisi od dužine delovanja,količine primene i tipa zemljišta.U prvih 24 sata nakon primene herbicida nije došlo do promene u broju ove grupe mikroorganizama.Delovanje linurona i alahlora uočeno je od sedmog dana ogleda,dok je fomesafen smanjio broj celulolizatora nakon trećeg dana od primene.Linuron je u odnosu na alahlor i fomesafen pokazao jači inhibitorni efekat kod oba tipa zemljišta.
