Herbicides to Kill Invasive Trees in Home Landscapes and Surrounding Natural Areas

A single-nozzle backpack sprayer is useful for foliar treatment of many woody invasive plants.

Several plant species that are invasive in natural areas of public lands also occur on private property. Invasive plants on private property that thrive within both landscaped and surrounding natural areas can serve as a source of infestation to other natural areas. Therefore, property owners are encouraged to remove invasive plant species from both areas. This 5-page fact sheet is a major revision that discusses different herbicides, hand-pulling, stump grinding, foliar herbicide application, cut stump herbicide application, basal bark herbicide application, hack-and-squirt, frill, or girdle herbicide application, licenses and training, and control of specific invasive plants. Written by K. A. Langeland and S. F. Enloe, and published by the UF Department of Agronomy, revised May 2016.

Body Fat and Health: How Can I Tell if I am at Risk for Health Problems?

Woman getting her weight.

Obesity is called an epidemic because there is a high rate of obesity in the United States. In fact, over 30% of all US adults were obese as of 2012, and more than two-thirds are either overweight or obese. This is concerning because excess body fat is linked to poor health and chronic diseases, such as diabetes and heart disease. The amount of excess body fat a person has is commonly sorted into weight status categories using Body Mass Index. This three-page fact sheet describes the body mass index and how to calculate it. Written by Kohrine A. Counts and Anne E. Mathews and published by the Food Science and Human Nutrition Department.

Engaging High Water Users in Water Conservation #2: High Water Users' Water-related Behaviors and Willingness to Act

John Cisar, a professor of Environmental Horticulture at the University of Florida's Fort Lauderdale Research and Education Center, is studying how turfgrass and other landscape plants can help prevent nitrogen from leaching through the soil into groundwater, Wednesday - Aug. 13, 2003. He said three years of research have shown that turfgrass is most effective in reducing nitrogen leaching and should be used in Florida landscapes. Other plants require more time to become established and slow nitrogen leaching through the soil.

Approximately 50% of Floridians’ daily water consumption is used for outdoor purposes, such as landscape irrigation; this is 20% higher than the national average. In order to alleviate the pressure on the precious water resources in Florida from various demands, increased public awareness and engagement in water conservation is needed especially among high water users. This four-page fact sheet is the second in a series discussing how Extension can improve high water users’ engagement in water conservation with a focus on high water users’ water-related behavior and willingness to act. Written by Pei-wen Huang and Alexa J. Lamm and published by the Department of Agricultural Education and Communication.

A chilling temperature is any temperature that is cold enough to cause plant injury but not cold enough to freeze the plant. Chilling injury can occur to tropical foliage plants if greenhouses become too cold or if plants are exposed to chilling temperatures outside of the greenhouse during packing and shipping. Dieffenbachia, commonly known as dumb cane, ranks among the top five most popular foliage plant genera produced and sold in the United States. This four-page fact sheet describes the chilling temperatures of Dieffenbachia cultivars in order to assist growers to better manage greenhouse temperatures.
