What do Floridians think about water issues? February 19, 2013

Although water is one of Florida’s most abundant resources, groundwater resources are being depleted by population growth, development and business and agricultural needs of the state. Residents and UF/IFAS Center for Public issues education (PIE Center) stakeholders routinely identify water as one of the most pressing issues in the state, according to PIE Center Director Tracy Irani, so water was the logical topic for launching the ambitious research series.

“Even though we are surrounded by water on all three sides, we’re finding that in this state, water is a resource to be concerned about,” Irani said. “There’s a greater and greater understanding that this resource needs to be conserved and that individual citizens have a role to play in that.”

Alexa Lamm, assistant professor of public opinion analysis in the UF/IFAS Department of Agricultural Education and Communication., developed and distributed an online survey in late 2012 to a panel of Florida residents demographically representative of the state based on 2010 Census results.

When asked to rank where water was most needed, state residents left their landscaping at the bottom of the list; 60.7 percent of surveyed citizens said having enough water for household landscaping was either highly or extremely important.

Agriculture held the highest need for plentiful water, with 88.6 percent of respondents saying it was extremely or highly important. Recreation followed at 86.1 percent and golf courses at almost 84.8 percent. Commerce and industry ranked ahead of landscaping, as did freshwater resources and cities.

“People are more concerned with recreation activities and golf courses than they are with their own personal household landscapes,” Lamm said. “Water conservation efforts have been occurring and more people are more aware that their landscape doesn’t need as much water as they once thought.”

When compared to the needs of cities, commerce and recreation, Lamm speculated that Floridians seemed to be sacrificing their gardens for the greater good of the state.

It’s A Bird… It’s A Plane… It’s A Whitefly!!! July 13, 2012

I guess they never asked Superman to get rid of whitefly pests! Otherwise it would have been a painful defeat for the super hero against thousands of little warriors (each adult is approx. 2 mm long)

Whiteflies love South Florida and I am not kidding. Go outside and look at some palms or that black, sticky and sugary substance aka “honeydew” all over Miami-Dade county cars and landscape…yup! That was probably caused by an innocent whitefly population.

If you are annoyed by these white fellows, imagine growers and landscapers who have to deal with thousands of whiteflies attacking their crops. Just as an example, Ficus (rubber trees) used in fences are a heaven on Earth for one type of whitefly. Another whitefly likes pretty much any green plant (they are voracious)…Homeowners, pest control agencies, municipalities and green industry in general are literally pulling their hair to manage this pest.

The University of Florida Extension Office located in Homestead is putting together a program: “Whiteflies for ornamentals on in South Florida” August 7th with two Ornamental entomologists, your UF-Extension agent and industry representatives will be together in the same location for you to get all the research based information needed to learn how to identify and understand better types of management based on an accurate identification of each type of whitefly.
