Preplant soil compost or fumigation, rootstock disease resistance or tolerance, and previous tree or grass rows as management factors in apple replant disease

摘要

When orchards are replanted to maintain productivity, apple replant disease (ARD) often causes major problems. Soil fumigants sometimes control ARD, but biological and cultural alternatives are needed. This project evaluated disease-resistant apple rootstocks and preplant soil treatments with compost and a fumigant as methods to improve apple tree growth and productivity in a replanted orchard.
