Effects of quinclorac on soil microbes

The effect of quinclorac on the quantity of soil bacteria,actinomycetes and fungi were studied by the simulation of quinclorac concentration in soil.During the short time(from 0 d to 10 d) after quinclorac going into soil,the number of bacteria reduced significantly with the increase of quinclorac concentration(P0.05).Low concentration quinclorac promoted the growth of actinomycetes,and higher concentration of quinclorac inhibited the growth of actinomycetes.Therefore,the population of bacteria and actinomycete can be used as good indicators for the quinclorac pollution in soil.
