Because cultivated strawberries are genetically complex, conventional breeding of strawberry can be difficult. Therefore, gene editing can be useful when developing strawberry varieties. This 3-page document discusses CRISPR gene editing in strawberry. Written by Seonghee Lee, Cheolmin Yoo, Kevin Folta, and Vance M. Whitaker and published by the UF/IFAS Horticultural Sciences Department, February 2018.

Bloomify Red and Bloomify Rose, Two Infertile Lantana camara Cultivars for Production and Use in Florida

Lantana camara is a popular nursery and landscape plant in the United States; however, it is listed as a Category 1 invasive species to Florida due to its ability to hybridize with Florida’s native plant species Lantana depressa. In 2004, the UF/IFAS Gulf Coast Research and Education Center initiated a research program to develop two highly infertile L. camara cultivars, ‘Bloomify Red’ and ‘Bloomify Rose’. This five-page document discusses the production and characteristics of these cultivars. Written by Zhanao Deng and Sandra B. Wilson and published by the UF/IFAS Environmental Horticulture Department, October 2017.

Biology and Management of Thickhead (Crassocephalum crepidioides) in Ornamental Crop Production

Typically found in shadehouses and shaded areas of nursery production, thickhead grows aggressively in containers and can outcompete nursery crops for water, nutrients, and light. This erect, sparingly branched, herbaceous annual, grows up to 4 feet tall and germinates over a wide range of pH, salt, and temperature conditions. This four-page fact sheet describes thickhead (Crassocephalum crepidioides) and various methods for its control in ornamental crop production. Written by Allison Bechtloff, Shawn Steed, Chris Marble, and Nathan Boyd and published by the Environmental Horticulture Department.

Spotted Wing Drosophila in Florida Berry Culture

Male adult spotted wing drosophila
Spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), is an invasive pest that was introduced into Florida in 2009. Spotted wing drosophila survives well under Florida’s climatic conditions. In 2014, losses to berry crops in Florida were estimated at $35 million. Losses are due to maggot-infested fruit, which is unacceptable for the fresh berry market, and puncture holes in the fruit made by egg-laying females. The holes lead to secondary infection by fungal and bacterial pathogens. This 4-page fact sheet written by Lindsy E. Iglesias, James F. Price, Craig R. Roubos, Justin M. Renkema, and Oscar E. Liburd and published by the Department of Entomology and Nematology describes the flies and some strategies to identify them and manage them in berry operations.
