Product Description


FIESTA® Turf Weed Killer is a selective post-emergent, broadleaf weed killer that uses a specially formulated iron chelate solution. Fiesta® works quickly, delivering visible same-day results, even in cool weather.  This bio-herbicide is perfect for spot treatment of broadleaf weeds in lawns, turf, parks ,playgrounds and athletic fields.

*For best results apply with Yucca Extract*


Iron HEDTA has no expected toxic effect on honey bees when used as directed.


Fiesta is Registered with the EPA as a Biopesticide and meets these 3 qualifications:

·       Only has efficacy against the target pest

·       No concerns associated with human health or the environment

·       Non-toxic mode of action



"We have observed that Fiesta is very consistent in providing broadleaf weed control in our trials. Multiple applications are required, and even then we don’t get 100% control, but it is more consistently effective than any other selective alternative to synthetic herbicides we have evaluated."


-Matt Elmore, Rutgers Extension Service Weed Science Specialist



"The use of high rates of chelated iron, available in products such as FIESTA®, have been shown to provide excellent post-emergence control of many broadleaf weeds. This technology has been in use in Ontario, Canada for many years since the “Cosmetic Pesticide Ban” from 2010 that removed ALL synthetic pesticides from the lawn care market. "

-Dr. Frank S. Rossi, Cornell Extension Turfgrass Specialist
