Edit Pecan Disease
Common Name
Latin Name
Description
this disease occurs on the mature pecan leaflets. 'Kanza,' 'Stuart,' and 'Dodd' appear to be susceptible in mid-summer, as are some native pecans. Occurrence is mainly in orchards and groves that are not sprayed for pecan scab.
Disease Life Cycle
The fungus overwinters on leaf tissue. Since this is a minor disease issue in most areas, in-depth understanding of its life cycle is not available.
Disease Symptons
Brown leaf spot presents with reddish-brown, small circular lesions. As the lesions develop, they become more irregular in shape and cross over veins. Older lesions turn gray. Severe infestations can cause premature defoliation.
