Achieving Sustainable Cultivation of Apples. Cambridge, UK:Burleigh Dodds Science Publishing. p. 403-424. Interpretive Summary: Technical Abstract: Bacterial diseases of plants are usually difficult to control and often require a combination of control measures to successfully manage the disease. There are often stark differences between the means available to control bacterial diseases in annual crops versus a woody tree crop, such as apple. Fire blight is a serious economic threat to apple production in regions of the world where it occurs. Due to the economic importance of fire blight to the pome fruit industry, both fire blight and E. amylovora have been extensively studied since the late 1800s with over 5,000 literature citations (van der Zwet et al. 2012). It will therefore be used as an example for the key issues and challenges presented by bacterial diseases for apple production with sections on its history and spread around the globe, economic impact, symptoms, disease biology, and management. There has been less research conducted on other bacterial diseases of apple, including blister spot, crown gall and hairy root, bacterial blossom blast, and bacterial blister bark, which will be discussed in less detail. Apple proliferation, which is caused by a phytoplasma, is also of economic importance in regions of the world where it occurs and will be discussed in a separate section on diseases caused by phytoplasma. A case study will be presented on current efforts to develop apple cultivars that are resistant to fire blight disease. |
