<i>Cladosporium caryigenum</i> Species of fungus

Cladosporium caryigenum is a synonym of Fusicladium effusum, the plant pathogen which causes pecan scab. Pecan scab is the most economically significant disease of pecan in the southeastern United States. In 2010, Seyran and colleagues used sequencing of the mitochondrial gene for cytochrome b to conclusively classify the pecan scab fungus as Fusicladium effusum.

Meloidogyne partityla is a plant pathogenic nematode infecting pecan. One of the first described cases of this nematode where noted in pecan trees in South Africa by Brito et al. (2013). It is thought to have been introduced into South Africa by pecan seedlings that came from the United States. Today, this nematode is seen infecting pecan trees in Arizona, Arkansas, Florida, Georgia, New Mexico, Oklahoma, and Texas. They not only infect pecans, but they also infect the California black walnut, English walnut, shagbark hickory, and laurel oak. The first report in the US, was reported in South Carolina in which it infected laurel oaks but later started infecting neighboring pecan trees in the shared orchards. The health of infested trees continue to decline every year.

<span class="mw-page-title-main">Butter pecan</span> Flavor of ice cream, cakes, and cookies

Butter pecan is a flavor, prominent especially in the United States, in ice cream, cakes, and cookies. Roasted pecans, butter, and vanilla flavor are used in butter pecan baked goods. Butter pecan ice cream is smooth vanilla ice cream with a slight buttery flavor, with pecans added. It is manufactured by many major ice cream brands. A variant of the recipe is butter almond, which replaces the pecans with almonds.

Pecan anthracnose is a fungal disease of pecan trees caused by the ascomycete Glomerella cingulata (Stoneman) Spauld. & H. It is a widespread disease found wherever pecan trees are grown. Pecan anthracnose has been reported as far back in time as 1914, and as far away as Argentina. Glomerella cingulata has two anamorphs which cause disease on pecan trees, Colletotrichum gloeosporioides and Colletotrichum acutatum. The occurrence of Colletotrichum on pecans has contributed to a significant decline in pecan production in various years. An increase in the incidence of pecan anthracnose is highly correlated with heavy rainfall, especially heavy rainfall occurring in early spring. The severity of symptoms increases as the season progresses, often culminating in leaf drop in the late autumn. This defoliation is linked to lower yield and poorer quality of nuts.

<span class="mw-page-title-main">Pecan scab</span> Fungal disease of pecan trees

Pecan scab is the most economically significant disease of pecan trees in the southeastern United States. Venturia effusa is a fungal plant pathogen that causes pecan scab. The fungus causes lesions and tissue death on pecan twigs, petioles, leaves, nuts and shucks beginning in early spring, with multiple cycles of infection repeating until late summer. Wind and rain spread the fungus to a susceptible host. Control of the disease is achieved by fungicide, sanitation and, in some cases, quarantine.

The Elliot Pecan, or Elliott Pecan, is a pecan variety planted predominantly in Georgia and Florida. The nut is distinguishable by its smooth shell and small, tear-drop shape. The first Elliot tree was a seedling in the lawn of the American lumberman Henry Elliot in Milton, Florida. The Elliot Pecan tree is among the most disease-resistant pecan trees planted in the Southeastern United States.

The 1965 NCAA College Division football season was the tenth season of college football in the United States organized by the National Collegiate Athletic Association at the NCAA College Division level.

Pecan bacterial leaf scorch is a disease of the pecan tree that is common throughout the production regions of the United States caused by the pathogenic bacterium Xylella fastidiosa subsp. multiplex. The pathogen was initially discovered to be coincidentally associated with symptoms of pecan fungal leaf scorch in 1998 and has subsequently been found to be endemic in the southeastern United States, as well as Arizona, California, and New Mexico.
