On August 3, 2022 the first anthracnose lesion was reported on an early maturing banana pepper variety in Kent County. With the recent discovery of a new and more aggressive species of anthracnose (Colletotrichum scovillei) in 2021, it is important that growers in this area are aware of this occurance.
All pepper fruit, from freshly set to fully mature, are susceptible to infection from this anthracnose species and should be protected by specific fungicides weekly. Table 1 outlines products currently available for use against anthracnose in peppers.
