Current economic conditions demonstrate the need for disease-resistant, highly productive pecan (Carya illinoinensis) cultivars for the southeastern United States that can generate high yield potential and can be produced at a reduced cost to enhance

Pecan scab, caused by Venturia effusa, is the most economically damaging disease of pecan in the southeastern United States, and annual epidemics are most effectively managed through multiple fungicide applications. The fungicide applications can be

An 18-ha commercial pecan orchard was sampled over 3 years to study the spatial and temporal variation in fungicide sensitivity of Venturia effusa, cause of pecan scab. The orchard was divided into a two-dimensional, 8 × 8 grid of 64 quadrats, each

The most destructive disease of pecan in the southeastern United States is scab, caused by Venturia effusa. Incidence (I)-severity (S) relationships have not previously been characterized in this pathosystem, but incidence measures can save time and

Scab on pecan is caused by Venturia effusa, and epidemics of the disease can cause substantial yield loss and associated cost of control. Phosphonate fungicides have been widely used since 2011 to manage this disease, and are a valuable class of fung

The quinone outside inhibitor (QoI) fungicides are known for their inherently high resistance risk owing to substitutions in amino acid residues 129, 137, or 143 of the cytochrome b gene of phytopathogens. In Venturia effusa, cause of pecan scab, an

BackgroundPecan (Carya illinoinensis) is an important native nut crop in the southern USA. In the Southeast, scab (caused byVenturia effusa) is a major constraint to production, and can result in significant yield losses. The breadth of sources of re

In the southeastern USA, the most widespread and damaging disease of pecan is scab, caused by Venturia effusa. Although scab can be controlled using conventional chemical methods, organic pecans that attract a premium price mandate the use of organic

Venturia effusa, which causes pecan scab, has developed resistance to fungicides that were once effective. Over 2 years, laboratory-based sensitivity of fentin hydroxide (TPTH) and tebuconazole in V. effusa and their efficacy under field conditions w
