Botrytis Blossom Blight of Southern Highbush Blueberry

Updated: Mar 18, 2019

Philip F. Harmon

Botrytis blossom blight is an important disease of blueberries and several flowering ornamental plants. The fungus, Botrytis cinerea, most commonly infects and blights wounded or senescent plant tissues. As a blueberry bush blooms, corollas (the fused petal of the flowers) senesce and become quite susceptible to infection. Ideally the corolla should drop from the flower after pollination but before senescence occurs. Frost damage on tender new growth may wound the plant, delay petal drop, and facilitate infection by the fungus.
