OligoActiv Copper

OligoActiv Copper is a liquid with a high concentration in copper used to prevent and correct copper deficiencies. Due his high solubility and special formulation enhance plant uptake and making it more bioavailable for the plant. Because chelates enter the plant easily they are extremely useful for rapidly correcting nutrient deficiencies.

OligoActiv Copper as a copper product it exercises certain preventive control on endoparasitic fungi and bacteria due to the fungicidal and bacterial action of the micronutrient. Furthermore, its use as a defoliant in certain crops (e.g. fruit trees) is recommended. This causes premature leaf fall, accelerating the entry of the crop into dormancy to anticipate pruning. It’s an ideal product to complement NPK fertilizers. It can be applied by fertirrigation and foliar application. The product does not cause any burns or phyto-toxicity on the surface of the leaves or to the root system. Foliar applications have been carried out in tomato and cucumber crops with fruit and no spot or damage has been detected. Anyhow, foliar application test is recommended before application.

OligoActiv Copper is compatible with the majority of manures and phyto-sanitary products normally used. It should not be mixed with alkaline reactive products. It is recommended to perform a test before mixing.
