|Alternaria sp. fungus that has infected a bell pepper with suncald.|
In addition, this sample appeared to have a black fungal growth, covering the sunscald area. This is an Alternaria sp. (a fungus pathogen) that can invade the damaged tissues (from sunscald or other issues) on the fruit and can continue to cause injury.
Alternaria sp. is controlled by avoiding conditions that predispose peppers to infection. There are no approved fungicides or biocontrol agents known for postharvest application to pepper fruit. If possible, planting should be scheduled so that harvest does not occur during very hot or cold weather, or drought. Grow pepper cultivars that provide good shading of fruit and be sure that the fertilization includes adequate calcium.
