Microbial community of apple replant soils treated with fumigation or seed meal

Brassicaceae seed meal (SM) formulations were compared with pre-plant 1,3-dichloropropene/chloropicrin (Telone-C17®) soil fumigation for the ability to control apple replant disease and to suppress pathogen/parasite re-infestation of organic orchard soils at two sites in Washington State. The study also examined capacity of the SM treatment to minimize re-establishment of the causal pathogen populations and the potential contribution of altered rhizosphere microbiology to disease suppression.
