Effects of biocontrol bacteria and earthworms on the severity of Alternaria brassicae disease and the growth of oilseed rape plants (Brassica napus)

This study did not give any clear indication of the usefulness of B. amyloliquefaciens for biocontrol of plant pathogens such as Al. brassicae when growing plants in natural soil. In addition, no significantly positive effects from the tested earthworm species were seen.
