Benefits of HEROCU Copper Fertilizer
✔ High copper concentration – 380 g Cu/L
✔ Thanks to modern production technology and high-temperature micronisation, extremely fine copper oxychloride particles are obtained. These particles are evenly dispersed and remain stable in suspension.
✔ The formulation contains substances that improve adhesion and wetting while helping the particles spread evenly. As a result, HEROCU 380 AZUL copper fertilizer forms a uniform and persistent coating on the plant surface.
✔ In addition, the formulation helps the particles remain on the leaf surface for longer. This improves coverage, reduces the risk of wash-off and extends the contact time of copper with the treated surface.
✔ Thanks to these properties, HEROCU 380 AZUL copper fertilizer is well suited for foliar application where uniform coverage and effective copper nutrition are important.
✔ Easy-to-use liquid suspension
✔ Suitable for use in organic farming in accordance with applicable legislation

Compatibility of the Copper Fertilizer
Do not mix with products that have a very acidic or very alkaline reaction. When preparing tank mixes with other products, it is recommended to carry out a compatibility test beforehand.
Under certain conditions, copper may cause phytotoxicity in sensitive crops or varieties. Therefore, a small-scale trial application is recommended before use over a larger area.
