Florida Homeowner Herbicide Guide: Considerations, Applications, and Selection

When applying herbicides, be sure to wear long sleeves and pants, closed-toe shoes, socks, gloves, and any other required PPE listed on the label to avoid potential exposure.

While some people opt for professional lawn maintenance companies, some homeowners may wish to perform their own landscape pest control in order to save money, to have more control of what is applied, or simply because they enjoy it. This EDIS publication is for Florida gardeners, horticulturalists and homeowners who want to utilize herbicides to control weeds in their landscape. This new 9-page publication of the UF/IFAS Environmental Horticulture Department discusses common herbicides available at retail stores and how homeowners can use these them safely and effectively.

Butterfly Pea (Clitoria ternatea) Flower Extract (BPFE) and Its Use as a pH-Dependent Natural Colorant

BPFE extract at normal pH (blue), lowered pH (green), and raised pH (purple)

Butterfly pea (Clitoria ternatea), a twining vine native to Southeast Asia, produces deep blue to purple flowers that bloom nearly year-round in ideal conditions. When extracted in a liquid, the addition of a mild acid such as lemon or lime juice turns the naturally deep blue to purple color into a much lighter pink or purple color, giving the extract its color-changing ability. This new 5-page publication of the UF/IFAS Environmental Horticulture Department outlines the use of butterfly pea flower extract (BPFE) as a pH-dependent natural colorant, including an explanation of the science behind the color change, detailed parameters for flower extraction, instructions for storage and processing of the extract as well as a discussion of some of the other benefits of using BPFE. Written by Sean Michael Campbell and Brian Pearson.
