chelated copper herbicide Chelated Copper EDTA Fertilizer 14%Chelated Copper EDTA 14% Cu is a single ingredient, 100% water soluble micronutrient fertilizer that corrects copper deficiency in plants. The EDTA chelate holds copper plant available across roughly pH 4 to 9, including the neutral and alkaline soils where unchelated copper sulfate reacts with carbonates and phosphates and becomes unavailable to roots. Copper is an essential micronutrient and a cofactor for more than 30 plant enzymes involved in
Chelated Copper EDTA 14% Cu is a single-ingredient, 100% water-soluble micronutrient fertilizer that corrects copper deficiency in plants. The EDTA chelate holds copper plant-available across roughly pH 4 to 9, including the neutral and alkaline soils where unchelated copper sulfate reacts with carbonates and phosphates and becomes unavailable to roots.
Copper is an essential micronutrient and a cofactor for more than 30 plant enzymes involved in photosynthesis, respiration, and lignin formation. Because copper is immobile in plants, deficiency shows first on new growth as pale young leaves, twisted shoots, and tip dieback. This product dissolves completely with no residue, making it suitable for soil application, foliar spray, drip fertigation, and hydroponic systems without clogging emitters.
Copper is a trace nutrient with a narrow margin between deficiency and toxicity, and it accumulates in soil — confirm the need with a soil or tissue test, follow label rates, and retest before repeat applications. This is a nutritional product, not a fungicide.
CDFA registered and independently lab tested for heavy metals, with results consistently well below required limits. Copper is highly toxic to sheep — do not apply where sheep graze.
