Pecans are one of the later budding trees out there, for good reason. It usually allows
some protection against late freezes. Unfortunately, our last freeze event did damage
some newly exposed leaves at our Clarksville location (Figure1). There was minimal
damage though, and most new growth looks fine. The catkins are beginning to form and
the trees are getting ready for pollination. It is important to remember one of the
critical pecan scab management timings is a pre-pollination spray when leaves are
about 1 inch in length. Many trees have reached this point. Managing pecan scab is
essential to produce a good crop and will require additional cover sprays every 14
days. Pecan scab was terrible last year! For a listing of pecan scab products please
review the MP154.
