Phomopsis amygdali causes peach shoot blight of cultivated peach trees in the southeastern United States

摘要

Strains of Phomopsis were obtained from peach, Asian pear and plum in the USA and from almond in Spain and Italy. Examination of the morphological, cultural and molecular characteristics of these strains showed that the Phomopsis amygdali on almondin Europe is the same as the fungus found on peach in the USA. The species of Phomopsis on plum and Asian pear in the United States is different from P. amygdali.
