“…The European Union regulations enforce maximum Cu residue levels (i.e., 5 mg/kg fresh mass in or on foods). However, agricultural goods with levels of Cu residues exceeding this legal threshold are reported (Kurnik et al 2012). These copper spray residues may have adverse effects on agricultural products, on both external and internal quality parameters including appearance or taste.…”

Since the initial use of Bordeaux mixture in 1885 for plant disease control, a large number of copper-based antimicrobial compounds (CBACs) have been developed and applied for crop protection. While these compounds have revolutionized crop protection in the twentieth century, their continuous and frequent use has also raised concerns about the long-term sustainability of copper (Cu)-based crop protection system. Here, we review CBACs used in crop protection and highlight their benefits and risks, and potential for their improvement and opportunities for further research to develop alternatives to CBACs. The major findings are (i) the relatively high toxicity to plant pathogens, low cost, low mammalian toxicity of the fixed Cu compounds, and their chemical stability and prolonged residual effects are major benefits of these compounds; (ii) phytotoxicity, development of copper-resistant strains, soil accumulation, and negative effects on soil biota as well as on food quality parameters are key disadvantages of CBACs; (iii) regulatory pressure in agriculture worldwide to limit the use of CBACs has led to several restrictions, including that imposed by the regulation 473/2002 in the European Union; and (iv) mitigation strategies to limit the negative effects of CBACs include their optimized use, soil remediation, and development and application of alternatives to CBACs for a sustainable crop protection. We conclude that recent research and policy efforts have led to the development of a number of alternatives to CBACs, which should be further intensified to ensure that growers have sufficient tools for the implementation of sustainable crop protection strategies.

“…The uncontrolled release and inefficient metabolism of the reactive oxygen species are the major consequences of CuNP applications (Anjum et al 2015). The cupric ions released by CuNPs do not form complexes with other molecules and may cause phytotoxic effects in crop plants (Kurnik et al 2012).…”

Nanotechnology is a rapidly evolving field that has the potential to revolutionise food systems and counter the present-day challenge of food security. It envisages taking agriculture from the era of indiscriminate natural resource use and environmental degradation to the brave new world of advanced systems with enhanced material use efficiency and targeted applications to reduce crop losses caused due to abiotic-biotic stresses as well as to give due considerations to the environment. To manage plant diseases and insect pests, pesticides are inevitably used in agriculture. However, the higher dosage of these chemicals on a per hectare basis has resulted in many environmental and health hazards. To tackle the conventional pesticide related issues, a new field of science called nanotechnology has led to the development of nanopesticides that have less active ingredients, but better efficiency. The nanopesticides contain the carrier molecule or the active nanosized ingredient with a very high surface area to the volume property that provides them unique exploitable-advantages. Several formulations, viz., nanoemulsions, nanosuspensions, nanogels, metal compound-based nanopesticides, have been developed for different modes of action and vivid applications. The biggest advantage comes due to the small size of the particles that help in properly spreading the ingredients on the pest surface and, thus, producing a better action than conventional pesticides. The use of nanoparticles in the form of nanopesticides, nanofertilisers, and nano delivery systems is on the increase day by day due to their higher efficiency and reduced dosage requirements. However, human beings and other organisms are also getting exposed to the nano-entities during the application or afterwards. The interactions of these engineered nano-entities with biological systems are relatively unknown thus far. Therefore, before their wider usage in crop production and protection, a better understanding of their interactions, and adverse effects, if any, is also crucial for a sustainable transition.

“…Both the CFF1 and Cu-ZnB1 treatment during each growing season at 120 DAT reduced the disease index by 45.4-78.7%, compared with BDM and control treatments. Copper fungicides have been found to lessen the spore germination rate of pathogenic bacteria and the growth of fungal hyphae [35]. When copper fungicides were sprayed on the leaves, Cu ions were released and destroyed cell protoplasm, thus killing the pathogenic bacteria.…”

“…A large accumulation of copper was observed in soils of apple and grapevine plantations resulting from longterm application of BDM and this has led to detrimental effects on soil fertility and local ecologies [35]. Longterm foliar application of copper fungicides can lead to excessive Cu accumulation within the soil, through direct application, drift, or dripping from leaves [45,46].…”
