‘Florida127’ is a new strawberry cultivar released from the University of Florida in 2013, the fruit of which are eligible for marketing under the Sensation™ brand. It is a short-day plant adapted to annual, winter plasticulture growing systems. The plant is moderately compact, robust, and upright with long pedicels, making the fruit easy to harvest. This 4-page fact sheet provides information and recommendations based on several years of testing in field plots in west-central Florida. Comparisons are made to ‘Florida Radiance’ and ‘Strawberry Festival’ for disease resistance. Written by Vance M. Whitaker, Craig K. Chandler, and Natalia A. Peres, and published by the UF Department of Horticultural Sciences, October 2014. (Photo by Vance M. Whitaker)
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?

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.

‘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. This 4-page fact sheet was written by Vance M. Whitaker, Craig K. Chandler, Bielinski M. Santos, and Natalia A. Peres, and published by the UF Department of Horticultural Sciences, June 2013.
Powdery 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. This 4-page fact sheet was written by N. A. Peres and J. C. Mertely, and published by the UF Department of Plant Pathology, May 2013.
Anthracnose fruit rot is an important disease for strawberry worldwide. Lesions appear as dark, sunken spots on infected fruit. This 4-page fact sheet was written by James C. Mertely and Natalia. A. Peres, and published by the UF Department of Plant Pathology, September 2012.
Colletotrichum 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. This 3-page fact sheet was written by Natalia A. Peres and Steven J. MacKenzie, and published by the UF Department of Plant Pathology, September 2012.
