Expanding citrus market access using a systems approach to control black spot: Reducing CBS to meet citrus market requirements

摘要

Currently the only Australian citrus that can access the lucrative United States (US) market is that grown in areas that are free from fruit flies and citrus black spot (CBS), a fungal disease. For fruit grown in areas with fruit flies and black spotto access the US market, control measures or treatments must be developed that meet the requirements of US quarantine authorities. Preharvest control measures and postharvest treatments have been developed against fruit flies. However, while current disease management strategies provide a high level of CBS control which is acceptable to existing domestic and export markets, they have never been proven to control black spot to the level Required by US quarantine authorities.
