Iron Selective Weed Killers (For Spraying on Turf to Kill Only Weeds)

Fiesta® Selective Weed Killer is a selective, broadleaf weed killers that kill only the weeds and not the desired turf.  Using a specially formulated iron solution, Fiesta is a game changer in the organic lawn care industry, the first effective weed killer that Does Not contain the synthetic weed chemicals 2,4-D or Dicamba.  The choice of professional applicators, Fiesta iron-based weed killer leaves lawns healthy and weed-free!

Fiesta works quickly, delivering visible same-day results, even in cool weather. With a unique ground breaking iron-based formulation, Fiesta is highly effective and has no unpleasant odor.

Fiesta Application Instructions

Large Areas (Broadcast Sprays):

  1. Add 5 oz. of Fiesta per gallon of water.
  2. Apply 2.5 gallons of water per 1,000 sq. ft. (or 12.5 oz. product per 2.5 gallons of water per 1,000 square feet).
  3. Repeat in 3-4 weeks for optimal knockdown of weeds.

Spot Sprays:

  1. Use 5 oz. of Fiesta per gallon of water and spray enough to wet weeds as needed.

    Fiesta General Application Notes:

    • Thoroughly spray weeds to point of runoff.
    • Ensure turf is well watered prior to application.
    • Do not apply when the daytime temperature will be below 50°F or above 85°F.
    • Do not apply to bentgrass.
    • Iron can stain some stone, concrete, clothes, equipment and other such things. Any desirable plants or structures accidentally contacted should be rinsed with water.
    • Do not apply to stressed lawns, such as drought stress.
    • Use standard spray equipment, with a coarse nozzle, such as a hand-held or backpack sprayer.  Hose-End sprayers are not compatible.
    • Repeat treatment in 3 to 4 weeks for best results and a longer-lasting weed kill.
    • Occasionally a darkening of the grass leaf blades can occur; however the grass will recover within a few days to weeks.
    • Allow 3 hours before rain or watering so the product can dry.
    • Do not apply during windy conditions to avoid over-spray.
    • May leave a rusty stain on concrete, pavers or other lightly colored areas; avoid such areas when spraying turf.

        Great price for a great product
        Color: Coal Black
        Excellent quality and great price to boot. Easy to assemble and folds up easily to be stored. We are using it as a privacy screen when we have company that needs to sleep on the couch and also to block off a hallway leading to a guest suite. It looks great and is as described in the ad

        No.
        Color: Coal Black, Color: Coal Black
        This was horribly made and a nightmare to put together. You have to basically bend the bars to get the coverings attached. The sizes don't match. The stickers that label the parts are impossible to remove and if you do get them off theres a lot of residue left behind. On top of that once it was put together I noticed theres a big dirty foot print on it which is definitely not mine.

        You have to add weight to it
        Color: Coal Black
        It does its job and it was easy to put together but it's a little on the flimsy side and it will easily be knocked down. So you're going to have to figure out a way to make the legs heavier? I used cinder blocks, single cinder blocks and it works just fine. Just know that it will knock over super easy

        My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.
