Pecan Tree – Ways To Treat Pecan Scab

Q: I have a pecan tree that is suffering from pecan scab. I read where the only way to treat it is by spraying the whole tree. I can’t accomplish that. Is there an alternative? 

A: There is not an alternative. Some varieties of pecan are more resistant to the disease than others but that’s nothing you can change now. ‘Elliot’, ‘Sumner’ and ‘Amling’ are resistant to scab. ‘Desirable’ and ‘Papershell’ are not. Springtime weather has much to do with how much scab disease your trees get each year.
