Abstract:
The soybean root rot is a world-wide soil borne disease and seriously endangered the soybean production.Its pathogens are many fungi，so biocontrol is difficult by single bio-fungus.The tests were conducted to probe into the possibility of combination and evaluate combining ability of biocontrol strains by indagating their growth speed，spore quantity，spore bourgeon and antagonistic action of Trichoderma strains FMM5，FMM9 and FMM35，bacterium B7 and Chaetomium CHZ1 in laboratory，the biocontrol agents screened were used to the trial of controlling effect in greenhouse.The results indicated that these strains were different in growth speed，spore quantity and spore bourgeon.Through analyzing，C1(FMM9 and FMM35) was better in combining effect，it had low antagonistic action between combining fungus and effectively controlled soybean root rot and speeding soybean seedling growth，it can be studied further.
