In a mild wet spring blossom wilt can be more of a serious problem. This fungal disease affects plums, apples, pears, cherries and related ornamental trees. It kills blossom spurs and small branches. The damage begins at flowering time where the blossom trusses wilt and turn brown, having a scorched appearance. In bad cases the shoots are also killed.
Cultural solution: Remove infected blossoms and dead twigs in spring.
There is currently no chemical control for this problem.
