Cuperdem Chelated Copper Systemic

Cuperdem Chelated Copper Systemic

R150.00 – R310.00

Cuperdem is an organic, chelated copper treatment that plants actually absorb — instead of sitting on the leaf as gritty particles the way standard copper sprays do. Bound to a natural sugar acid called heptagluconic acid, it dissolves fully in water and moves systemically through roots, stems, and leaves.

Because it’s fully water-soluble, a lower dose covers more surface area and leaves far less copper behind in your soil over time.

  • Enhances crop immunity
  • Improves photosynthesis
  • Combats fungal diseases
  • Works as foliar spray, soil drench, or through drip systems

OMRI Listed and SHC certified for organic growing, with a zero-day harvest interval on edible crops like lettuce, fruit, and vegetables.

Cuperdem Chelated Copper Systemic — Copper Your Plants Can Actually Use

Copper is one of the most important nutrients a plant can get. It’s essential for photosynthesis, strong stems, and natural disease resistance.

Most copper products — deficsulphate, oxychloride, hydroxide — barely dissolve in water. Instead of soaking in, they sit on the leaf as gritty particles, rinse off in the next watering, and then settle into the soil. Over time this can harm soil life , while the plant itself remains copper deficient.

How Cuperdem Works

Cuperdem binds copper to heptagluconic acid — a naturally occurring, fully biodegradable sugar acid. This locks the copper into a stable, water-soluble complex instead of a solid particle. The result: copper that dissolves completely, moves into the leaf or root on contact, and travels systemically through the whole plant. You get full coverage at a lower dose, with far less left behind in the soil.

What It Does For Your Plants

  • Enhances crop immunity — copper at the right level makes it harder for fungal and bacterial pathogens to take hold
  • Improves photosynthesis — copper is a building block of the enzymes plants use to convert light into energy
  • Combats fungal diseases — works as both a protective barrier and a systemic treatment
  • Feeds roots and leaves — fully water-soluble, so it works as a foliar spray, soil drench, or through drip systems
  • Keeps soil healthier long-term — lower doses do the same job as heavy conventional copper applications

Cuperdem effective rate

Is copper a “heavy metal”?

Yes, by the common physical definitions (density 8.96 g/cm³, a high-atomic-weight transition metal). Copper is an essential heavy metal (like iron and zinc), whereas lead, mercury, cadmium, and arsenic are non-essential and serve no biological role. Essential metals are homeostatically regulated by the body; the toxic four are not and tend to bioaccumulate.

  • OMRI Listed — approved for use in organic production
  • SHC (Sohiscert) certified — recognised organic farming input
  • Zero-day harvest interval — safe to use right up to picking day on edible crops like lettuce, fruit, and vegetables

For Cannabis cultivation: Because the final harvest is often dried and inhaled or vaporised, it is recommended to switch from foliar spray to a soil drench once flowering begins, rather than spraying the plant directly during flower.

How to Use Cuperdem Chelated Copper Systemic

Foliar spray (preventative) 1 ml per liter of water Every 15 days
Foliar spray (active infection) 2 ml per liter of water Every 10 days
