At the crop level, the main treatments in pear trees are centered on the fungus prevention and treatmentbecause if the atmospheric conditions for its development are met, its control is very complicated.

Source of copper for the prevention and control of pear diseases

Copper is a material that can be interesting to use, especially as a preventive measure. Due to maximum quantity restrictions in their application, more and more are being used complexed forms of coppers nutritional values ​​(less than 9% w/w) in pear treatments.

Different forms of organically complexed copper, such as gluconate or heptagluconate, have been shown to be able to introduce a significant amount of copper at the cellular level, even above other phytosanitary formulations.

In general, nutritional copper applications are usually recommended at the onset of budding. To promote leaf fall or preventive activity in the wood and greater persistence in the tree, there is a tendency to use phytosanitary forms of copper mixed with ureawhich promotes the rapid decomposition of leaves fallen to the ground and slows down the persistence of fungi in the soil.
