Pepper Anthracnose
In recent years, pepper anthracnose caused by Colletotrichum spp. has become a significant problem on some farms in southern New Jersey.
Unlike in tomato, where symptoms are only present in mature (red) fruit, pepper anthracnose can infect pepper fruit at any growth stage. Currently, there are no commercially-available bell or non-bell peppers with known resistance to anthracnose. [Read more…]

Heavy rain and wind can cause pepper anthracnose to flare up quickly!
Growers with peppers in fields with a history of pepper anthracnose should scout on a daily basis and initiate a fungicide program as soon as small fruit begin to develop. Pepper anthracnose can be very difficult to control once established. All bell and non-bell peppers are susceptible. Strip picking and removing all fruit from ‘hot spots’ when they first appear may help suppress spread of the pathogen.
Preventative fungicide applications should begin at flowering or fruit set. Use a heavy volume of water and make sure coverage is extremely good. Apply high rates of chlorothalonil or Manzate weekly and tank mix and/or rotate weekly with one of the following FRAC group 11 fungicides: Priaxor (fluxapyroxad + pyraclostrobin, 11), Quadris (azoxystrobin, 11), or Cabrio (pyracolostrobin, 11).
