Fusicladium effusum

No cultural control measures are particularly effective for managing pecan scab. However, ensuring that the trees in an orchard are adequately spaced to ensure good sunlight penetration and air-flow will help reduce the severity on susceptible cultivars (Cooper and Johnson, 1986). Planting susceptible cultivars in locations that are low-lying and wet should be avoided. Ensuring old shucks (husks) are removed from trees after harvest can also reduce sources of primary inoculum, although being a polycyclic disease this is probably of very limited value.
