“…Although the literature shows high copper use efficiency through foliar fertilization for bean crop (Karamanos et al, 2004;Hummes et al, 2019), the present study demonstrates the opposite. In this case, copper had a high affinity to adsorb into soil particles, and then become unavailable to plants uptaking.…”

Conducting a field study to investigate the effects of foliar and soil fertilization with copper on the nutritional and physiological parameters and grain yield of common bean. The experimental design was a randomized block, in a 2 x 5 factorial scheme. The first factor was the site of application of copper fertilization. The second factor was copper doses: 0, 1, 2, 3, and 4 kg ha-1 (6 replicates). The following were evaluated: leaf nitrogen and copper contents, relative chlorophyll index (RCI), gas exchange, photochemical efficiency of photosystem II, and grain yield. The data were subjected to analysis of variance and F test (p-value < 0.05), using the Scott & Knott for qualitative data and polynomial regression for quantitative data. Leaf Cu content was higher with soil application (4% and 28%), both at 24 and 45 DAE, respectively. Net photosynthesis reached a maximum index of 18.77 µmol m-2 s-1 with foliar Cu fertilization at the dose of 4 kg ha-1. The application of 2.0 kg ha-1 Cu was the one that led to the highest grain yields; however, soil application stood out with a yield about 12% higher of the foliar. Soil fertilization proved to be more efficient in terms of Cu absorption and RCI rates, improving grain yield (12%) in relation to foliar, especially at the dose of 2 kg ha-1. The dose of 2 kg Cu ha-1 provided the best differential profit, reaching US$ 581.96 ha-1 and US$ 503.01 ha-1 for soil and foliar application, respectively.

Agricultural Use of Copper and Its Link to Alzheimer’s Disease

Copper is an essential nutrient for plants, animals, and humans because it is an indispensable component of several essential proteins and either lack or excess are harmful to human health. Recent studies revealed that the breakdown of the regulation of copper homeostasis could be associated with Alzheimer’s disease (AD), the most common form of dementia. Copper accumulation occurs in human aging and is thought to increase the risk of AD for individuals with a susceptibility to copper exposure. This review reports that one of the leading causes of copper accumulation in the environment and the human food chain is its use in agriculture as a plant protection product against numerous diseases, especially in organic production. In the past two decades, some countries and the EU have invested in research to reduce the reliance on copper. However, no single alternative able to replace copper has been identified. We suggest that agroecological approaches are urgently needed to design crop protection strategies based on the complementary actions of the wide variety of crop protection tools for disease control.

“…The abuse of fungicides in vineyards is currently a cause of public concern, owing to their resulting presence as residues in water and wine products used for human consumption [18,19]. Cu-based fungicides, such as Cu(OH) 2 , copper oxychloride (3Cu(OH) 2 •CuCl 2 ), CuSO 4 , and Cu 2 O, are authorized and necessary for organic grapevine cultivation [20] (according to EC regulation 473/2002, 8 kg Cu ha −1 , which should be further decreased to 6 kg Cu ha −1 after four years of vine cultivation [21]). In addition, synthetic fertilizers and fungicides contain other heavy metals, such as mercury (Hg), cadmium (Cd), arsenic (As), lead (Pb), nickel (Ni), and zinc (Zn), which cause an alarming combination of environmental and health problems [22].…”

Climate change and disproportionate anthropogenic interventions, such as the excess of phytopharmaceutical products and continuous soil tillage, are jeopardizing viticulture by subjecting plants to continuous abiotic stress. One of the main physiological repercussions of abiotic stress is represented by the unbalanced redox homeostasis due to the overproduction of reactive oxygen species (ROS), ultimately leading to a state of oxidative stress (detrimental to grape quality). To these are added the direct and indirect damages caused by pathogens (biotic stresses). In light of this scenario, it is inevitable that sustainable techniques and sensitivity approaches for environmental and human health have to be applied in viticulture. Sustainable viticulture can only be made with the aid of sustainable products. Biostimulant (PB) applications (including resistance inducers or elicitors) in the vineyard have become interesting maneuvers for counteracting vine diseases and improving grape quality. These also represent a partial alternative to soil fertilization by improving nutrient absorption and avoiding its leaching into the groundwater. Their role as elicitors has important repercussions in the stimulation of the phenylpropanoid pathway by triggering the activation of several enzymes, such as polyphenol oxidase, lipoxygenase, phenylalanine ammonia-lyase, and peroxidase (with the accumulation of phenolic compounds). The present review paper summarizes the PBs’ implications in viticulture, gathering historical, functional, and applicative information. This work aims to highlight the innumerable beneficial effects on vines brought by these products. It also serves to spur the scientific community to a greater contribution in investigating the response mechanisms of the plant to positive inductions.
