FIESTA is a new Iron-based selective bio-herbicide with low toxicity that controls weeds, moss & algae on commercial and residential lawns, golf courses, parks, rights of way, schools and playgrounds.
FIESTA is a selective broadleaf bio-herbicide that works quickly, even in cool weather and is rainfast in 3 hours.
This effective organic weed killer's mode of action is to cause iron toxicity (oxidative damage) at the cellular level. Fiesta is quickly absorbed by the leaf tissue and transported down to the root. Toxicity of the contacted leaf tissue cells also occurs turning the leaves black or brown.
Broadleaf weeds (dicots) absorb more iron than grasses (monocots) which provides the mechanism of selectivity. For this reason, adequate coverage is important.
FIESTA controls and suppresses weeds such as:
Mix 1 part FIESTA with 24 parts water (5 oz. To 1 gallon)
Broadcast Treatment: Apply the mixed solution at a rate of 2.5-10 gallons/1000 ft2. Uniform coverage is important.
Spot Treatment: Thoroughly spray weeds to point of runoff using any standard hand-held or backpack sprayer. Use a coarse nozzle setting to reduce drift.
Repeat treatment in 3 to 4 weeks for best results.
