Fiesta® Turf Weed Killer is a selective, broadleaf weed killer that uses a specially formulated iron chelate solution. Fiesta® works quickly, delivering visible same-day results, even in cool weather and is rainfast after 3 hours.
Fiesta® is suitable for broadcast application or spot treatment and is a versatile, patented product that will help turf look its best, even in pesticide restricted areas such as parks, golf courses, cemeteries, sports fields, and playgrounds. It is ideal for turfcare specialists looking for an IPM approach to weed control.
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. This product is ideal for lawn care where pesticide bans exist and has been approved by the EPA’s Biopesticide Division.
Mode of Action
Iron is bound to a chelating agent, hydroxyethylene-diaminetriacetic acid (HEDTA), which keeps the iron soluble and readily available for plant uptake. Broadleaf weeds absorb Fiesta easily and in larger quantities than grass does, which leads to cellular damage and ultimate plant death in broadleaf weeds while grass remains unharmed.
