The University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) is asking Florida fresh citrus growers and packers to complete a brief, anonymous survey about a disorder some call “greasy green.”

The symptoms of the disorder are consistent with greasy spot, but a direct causal relationship has not been proven. The disorder may also be related to other possible factors. These include variety, nutrient application method/amount, phytotoxicity from different tank mixes and field temperatures.

As a result of the disorder, citrus fruit regreening continues to reduce fresh packouts for some Florida blocks later in the season. However, it is also impacting packouts as early as December.

Growers and packers are asked to offer input concerning conditions, cultivars, current practices and any other observations they might have related to this disorder. Take the survey here.  

Those with questions about the survey can contact Mark Ritenour, professor at the UF/IFAS Indian River Research and Education Center in Fort Pierce. His office number is 772-577-7359, his mobile number is 772-201-5548 or he can be reached at ritenour@ufl.edu.

Citrus grower George Hamner, of Vero Beach, Florida, referred to the greasy green problem in a recent Citrus Industry article.
