Florida Asian Soybean Rust Site  Page updated 5-2-07

2007: Current information regarding detections in FL and management recommendations is now posted to www.sbrusa.net. In addition, the Florida rust hotline is a nation-wide toll free number (866 361 9942) and can also be used to get updated information on soybean rust in Florida.

Pest and Host Information

1-06  Three new field hosts identified.  University of FL plant pathologists and agronomist identify soybean rust on three more legumes in Quincy trial.  Just before the winter holiday, Drs. Jim Marois and David Wright collected samples from a legume trial on the Quincy, FL, research farm.  Three of the legumes tested positive for soybean rust, and were confirmed by PCR analysis at the Gainesville, FL, lab of Dr. Philip Harmon and at the federal level by the APHIS/PPQ/NIS identifier, Mary Palm.  Detailed sample information and photographs have been submitted to Plant Disease for publication.  The three legumes identified were lima bean, kidney bean, and scarlet runner bean.  Pustules and spores were found on all three species.  The plants were fully mature but leaves had not yet begun to senesce.  No disease was found on the plants prior to 12-7-05; the plants were being scouted one last time before impending frost when they were found.  The legume trial is a collaborative effort with Dr. Glen Hartman, USDA Soybean Research Laboratory, IL.  The trial was not inoculated, but was exposed to spores produced by a border row from a soybean fungicide trial.

Researcher says not to panic over soybean rust on dry beans
Stop Soybean Rust News - Lenexa,KS,USA 5/2/2005 -- Now that Asian soybean rust has been found in volunteer soybeans in southwest Georgia with a field of commercial snap beans nearby, concern is ...

2005: Research is limited to growth chambers.  Inoculations may be done in growth chambers only (no greenhouses, no field studies).  An in-state permit Form 208 must be obtained through the Division of Plant Industry by contacting Dr. Tim Schubert at 352-372-3505.  The purpose of this restriction is to limit pathogen movement via humans.  The disease is localized presently and we don't want to be the mechanism of spread.  This restriction may be modified or lifted pending state-wide spread of the disease.   Permit form 1   Permit form 2 (Note, this restriction was lifted in 2006).

Fungicide Labels/Management

Management recommendations for the state of Florida are posted at http://www.sbrusa.net/; you will need to zoom in on FL to see them.  These are updated often, especially around conducive weather events and new county finds.
