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.

本研究对比了在华盛顿州两个地点，油菜籽饼（SM）配方与预植前1,3-二氯丙烷/氯化苦（Telone-C17®）土壤熏蒸剂在控制苹果再植病及抑制有机果园土壤病原体/寄生虫再次侵染的能力。研究还探讨了SM处理最小化病原体种群重新建立的能力，以及改变根际微生物群落对病害抑制的潜在贡献。
