Coppura is a liquid and acid-reactive formulation of concentrated copper sulfate pentahydrate, which is in hydrated ionic form. Coppura’s innovative technology allows copper ions to remain bioactive until they are fully absorbed by plant tissues. The great penetrative capacity of copper ions in plant tissues results in the required doses of Coppura being small compared to other traditional forms of copper preparations, thus reducing the toxicity of the preparation and the possibility of its application even in sensitive stages of plant development during the vegetative period.
