Camelina Production in Florida (SSAGR340/AG350)

Camelina (Camelina sativa (L)) is an old-world crop used primarily for oil. It can be grown under semi-arid conditions. Breeding efforts have resulted in very few improvements. It is a member of the Brassicaceae or mustard family and related to canola and cole crops. The seed is about 35% oil, and the oil is high in omega-3 fatty acid, which has been cited as having health benefits. Camelina meal can be fed to livestock, producing eggs and meat that are higher in omega-3 fatty acids. Interest in camelina is not only due to its high level of omega-3 fatty acids but because it is a renewable source of feedstock for biodiesel and advanced biofuels.

Postharvest Decay Control Recommendations for Florida Citrus Fruit (CIR359A/CH081)

Decay of citrus fruit is most often caused by fungal pathogens that grow and develop in the hot and wet conditions typical of the Florida climate. Losses from these diseases can be reduced by the practices discussed in this 6-page revised fact sheet written by Mark A. Ritenour, Jiuxu Zhang, and Megan Dewdney, and published by the UF Department of Horticultural Sciences, February 2011.

Citrus Black Spot: No Longer an Exotic Disease (PP281)

Citrus black spot is an emerging fungal disease that affects Florida citrus. Various symptom types occur about a month before harvest. Black spot has the potential to cause major economic damage to the fresh fruit industry and significant yield loss on processing varieties.

Turfgrass Disease Management (SSPLP14/LH040)

Turfgrass diseases are underappreciated because the biological organisms (plant pathogens) causing the problems are rarely observed. Fortunately, grasses maintained using proper cultural practices (water, mowing, and fertility) are not as likely to become diseased or be as severely damaged as grasses that do not receive proper care. This 11-page fact sheet discusses turfgrass diseases, their causal agents, diagnosis, and management. Written by M. L. Elliott and P. F. Harmon and published by the UF Department of Plant Pathology, February 2011.
