If you happen to notice small black spore-like spots on your pecan tree’s young leafs this spring you might be dealing with a disease common to the pecan tree called pecan scab fungus.
In severe cases, the disease can defoliate the tree, and reduce nut production. The disease can also spread to neighboring pecan trees. Cases of pecan scab fungus are typically worse in wet years.
But, there is a way to help protect your pecan tree from the disease now, before the first spring leafs arrive.
Apply a dormant fruit spray to your pecan trees now, before the spring buds. Use a high pressure sprayer, if you have access to one, to reach the top of the trees easier.
Make sure to apply enough of the spray so that the leaves are dripping and make sure to spray the trunk.
