Use advisory tool and links to guide strawberry disease management decisions

by Frank Louws, Center for IPM

All this wet weather will favor the main strawberry fruit rot diseases including Botrytis Fruit Rot (BFR) and Anthracnose Fruit Rot (AFR). BFR will be the main concern for most growers. We have not consistently identified plant sources with the AFR pathogen. Hopefully, AFR pressure will be low this year for most growers. Some strawberry fields have problems with angular leaf spot, caused by the bacteria Xanthomonas fragariae.

The Strawberry Fruit Infection Risk advisory tool shows HIGH risk for both BFR and AFR (see figure). Details of how to use this Advisory Tool are provided at https://ipm.ces.ncsu.edu/strawberry-fruit-infection-risk-tool/ or users can go directly to the map at: http://agroclimatenc.ncsu.edu/plantdisease/strawberry.aspx.

The following links provide details and up-to-date management recommendations about:
