Abstract

Pecans are great for eating out of the shell or in a myriad of recipes. But abundant pickings of high-quality nuts are only possible if the tree escapes the devastating disease called “pecan scab.” Caused by the fungus Fusicladium effusum, it is the most destructive disease of pecan in the southeastern United States. When scab is severe, most often when rainfall is above average, nut size is reduced, and total crop loss might occur.

Scientists at the Southeastern Fruit and Tree Nut Research Laboratory in Byron, Georgia, are working to help pecan growers mitigate the effect of pecan scab. Research leader Bruce Wood, plant pathologists Clive Bock and Michael Hotchkiss, and entomologist Ted Cottrell are using various approaches to reduce the impact of scab.

Their studies were described in a series of papers in the journals HortScience,Plant Disease, and Crop Protection.
