Fiesta Selective Weed Killer

Fiesta Selective & Post-Emergent Lawn Weed Killer is a selective, broadleaf weed killer that leaves lawns healthy and weed-free using a specially formulated iron chelate solution. Fiesta® works quickly, delivering visible same-day results, even in cool weather. And since Fiesta® is made from iron, it has no unpleasant odor during or after application, and pets and people can reenter the treated area once the spray is dry. Suitable for broadcast application or spot treatment, Fiesta® is a versatile, patented product that will help grass look its best, even in pesticide restricted areas such as parks, golf courses, cemeteries, sports fields, and playgrounds. This product is ideal for lawn care where pesticide bans exist.
