Eficaz Cu 80 is an ecological copper fungicide with systemic action and sulfur for foliar fungi. It also has bactericidal and plant defense stimulating properties. The elemental copper is complexed with an organic molecule that ensures high stability and ease of plant absorption.

100% complexed copper corrector for quickly and effectively preventing and correcting copper deficiencies caused by imbalances and/or poor assimilation.

Eficaz Cu 80 features 100% copper complexed with the most specific chelating agent for this metal: gluconic acid.

The copper in Eficaz Cu 80 acts as a catalyst for many enzymatic reactions, is part of many protein groups, and serves as a catalyst in the electron transport chain during photosynthesis.

Eficaz Cu 80 is compatible with most plant protection products and fertilizers used in agriculture. However, due to the wide variety of third-party products used in different mixtures, it is essential to carry out a prior compatibility and selectivity test.

Foliar Application

• Fruit trees, Citrus, and Olive: 200–300 cc/hl, 2–3 applications starting at bud break.
• Vegetables: 150–300 cc/hl, 3–4 applications depending on crop development.
• Grapevine: 200–300 cc/hl, until veraison.

Precautions:

• Do not apply during flowering or on copper-sensitive varieties.
• Do not apply at high temperatures. In humid or cold areas, phytotoxicity may occur.
• At high doses, it can cause defoliation of cotton and fruit trees at the end of the growing period.

Fertigation

• Fruit trees, Citrus, and Olive: 6–12 L/Ha, 2–3 applications: the first near vegetative dormancy, the second at bud break, and the last during full vegetative activity.
• Vegetables: 5–10 L/Ha, 3–4 applications depending on crop development.

Copper assimilation deficiencies are common in fruit trees, citrus, vegetables, grapevines, and extensive crops. In these crops, it is recommended to start applications before deficiency symptoms appear and during early growth or development stages.

Do not apply before fruit color change begins.
