Amaryllis Lesion Nematode, Pratylenchus hippeastri Inserra (EENY546/IN975)
Amaryllis lesion nematode is an important nematode pest of amaryllis in Florida. It reduces plant vigor, flower yield, and bulb size. As the nematodes tunnel through the root, the damaged cells die and collapse, forming lesions on the exterior and the interior of the root tissue. This 4-page fact sheet was written by William T. Crow, and published by the UF Department of Entomology and Nematology, January 2013. http://edis.ifas.ufl.edu/in975

Management of Insect and Mite Resistance in Ornamental Crops (ENY843/IN715)
Resistance of arthropods to crop management chemicals has been problematic since the early era of synthetic organic pesticides. During the 1970s and early 1980s leafminer outbreaks heavily damaged herbaceous ornamental crops such as chrysanthemum, gypsophila, aster, and marigold in fields, shade houses and greenhouses. Several effective insecticides including organophosphates, carbamates, pyrethroids, and a triazine were identified for leafminer control during the outbreak; however, control was short-lived as the leafminer developed resistance to each insecticide. This 11-page fact sheet was written by James F. Price, Elzie McCord, Jr., and Curtis Nagle, and published by the UF Department of Entomology and Nematology, November 2012. http://edis.ifas.ufl.edu/in715

UF/IFAS Finds Water Supplies Not as Threatened as Believed

droughtGAINESVILLE, Fla. — Although reports of drought conditions, water wars and restrictions have often painted a bleak picture of the nation’s water availability, a new University of Florida study (http://news.ufl.edu/2013/01/30/water-supply/) finds that conditions aren’t quite so bad as believed.

Jim Jawitz, a UF soil and water science professor, and Julie Padowski, a postdoctoral researcher at Stanford University, looked at the problem from a fresh perspective.

Past assessments of urban water supplies typically used what is known as a “runoff-based approach,” which takes into account factors such as river flows and rainfall amounts. These assessments do not consider the infrastructure used to maintain urban water supplies, such as water stored in aquifers, lakes, reservoirs or water that’s pumped into an area and stored.

So Jawitz and Padowski looked at 225 U.S. metropolitan areas with populations of more than 100,000 from an ‘infrastructure’ point of view.

The difference was dramatic. The older runoff-based studies found 47% of the U.S, population was vulnerable to water scarcity. The new infrastructure-based study found that only 17% of the population was vulnerable.

The researchers expected Atlanta – where legal battles over water rights with neighboring states initially prompted the researchers to tackle the survey – to be fairly vulnerable to water scarcity. But in fact Atlanta falls near the middle of the range – not nearly as vulnerable as they thought.

Another unusual finding: Miami, with its lush, tropical landscape, landing in the top 10 most vulnerable cities. Jawitz, a South Florida native, said although the Miami area generally enjoys an abundance of rain, it’s not stored anywhere. That means during periods of drought, the area becomes quite vulnerable.

Here’s a website that ranks the 225 largest U.S. urban areas based on water availability and vulnerability: http://soils.ifas.ufl.edu/hydrology/cities/

SWFWMD Offers Mini-FARMS Cost-Share Program – 2 of 2

MiniFarmsThe Florida Department of Agriculture and Consumer Services (FDACS) has established a cost-share program to help producers enrolled in FDACS BMPs purchase on-site weather stations and temperature sensors.  Funds are available on a first-come, first-served basis.

Producers who own operations with less than 300 acres of production land may apply for one station and up to five temperature sensors for each operation.  Producers who own larger operations may apply for one station and up to five temperature sensors for each 300 acres of production land on the operation(s).  FDACS will provide 75 percent of the cost up to a $25,000 maximum per producer, with a $5,000 cap per station/sensors set (see table below).

300 acres or less production land

1 weather station and up to 5 temperature sensors

75% with $5,000 cap for each operation

$25,000 total maximum per producer

More than 300 acres of production land

1 weather station and up to 5 temperature sensors per 300 acres

75% with $5,000 cap for each 300 acres

The stations will be installed by a company that agrees to meet the approved specifications, at the on-site location(s) the farmer designates.

These weather stations will collect real-time information throughout the year on rainfall, air temperature, relative humidity, dew point, wind speed, and wind direction.  The information will be accessible to producers on their smartphones and computers, through a University of Florida Automated Weather Network (FAWN) website.

Why purchase a weather station?
The use of weather stations helps producers:

  • Better determine when to delay irrigation after rainfall and when to irrigate during frost/freeze events, which can reduce water use and save costs on pump operation.
  • Better determine when to use fungicide or pesticide sprays or foliar fertilizer applications, which can avoid waste and save related costs.
  • Enhance the potential for reducing the pumping of surface and ground water and the runoff and leaching of fertilizers and other farm chemicals into water resources.

For more information on this cost-share program, and assistance with applying, please contact:
