Florida Strawberry Producers' Experiences with Anthracose and Botrytis Fruit Rot, and Producers' Use of the Strawberry Advisory System

Figure 1. Anthracnose lesions on a ripe fruit (Mertely and Peres 2012)Florida’s producers use fungicides to manage anthracnose and botrytis fruit rot diseases, which find favorable growth conditions in Florida’s climate and can reduce strawberry yields and profits. The Strawberry Advisory System (SAS) uses information about weather conditions and user-entered information about past fungicide applications to evaluate the potential spread of these diseases in strawberry fields. If the risk of disease spread is low, no fungicide application is recommended, allowing producers to save on fungicide application costs. In this study, we summarize the results of a 2012/2013 survey of strawberry producers, and focus on the questions, How significant is the impact of anthracnose and botrytis on Florida strawberry producers’ yields? What are the typical fungicide application frequencies used by the producers? What percent of strawberry producers use SAS? and Are there any effects of SAS subscription on producers’ fungicide application?

Impatiens Downy Mildew

Figure 2. Faint gray lines may be seen on the tops of leaves, or leaf edges may curl downward.Downy mildew on impatiens is of great concern throughout Florida. Winters in south Florida provide high humidity paired with cool nights, creating ideal conditions for disease development. Downy mildews are caused by several different species of pathogens that tend to be plant-host specific. Plasmopara obducens is the pathogen that affects impatiens. Some literature indicates that nighttime temperatures of about 50 to 72°F favor downy mildew, but the disease has been reported on impatiens year round in south Florida. This 4-page fact sheet was written by L. Sanagorski, B. Schall, A.J. Palmateer, and N.A. Peres, and published by the UF Department of Plant Pathology, October 2013.

'Florida Radiance' Strawberry

Figure 2. 'Florida Radiance' fruit. Credit: Tyler Jones, UF/IFAS Communications‘Florida Radiance’ is a strawberry cultivar released from UF/IFAS in 2008. As of 2012, it has become a major cultivar in Florida and other winter and early spring production regions worldwide. In all markets outside the United States and Canada, it is marketed as ‘Florida Fortuna’. In addition to commercial production, it has been tested for many years in field plots at the UF/IFAS Gulf Coast Research and Education Center in Wimauma and the Florida Strawberry Growers Association headquarters in Dover for disease, fruit, and plant traits.

Powdery Mildew of Strawberries (PP208/PP129)

Figure 2. Lower leaf surface of strawberry covered with powdery mildewPowdery mildew occurs in most areas of the world where strawberries are grown, infecting leaves, flowers, and fruit. Infected transplants are normally the primary source of inoculum for fruiting fields in Florida, but even disease-free fields can become infected by conidia blown in from neighboring fields. Fields with susceptible cultivars should be surveyed regularly for powdery mildew, especially early in the season. Usually, controlling foliar infection helps to prevent fruit infection.

Colletotrichum Crown Rot (Anthracnose Crown Rot) of Strawberries (PP238/PP156)

Figure 1.  Initial symptoms of Colletotrichum crown rotColletotrichum crown rot is caused by the fungi Colletotrichum gloeosporioides and Colletotrichum fragariae. Both pathogens kill strawberry plants by aggressively invading crown tissue. Crown rot is a serious disease in warm production regions, such as those in the southeastern United States.
