“…Antifeed-ant, repellent, irritant, growth inhibition, and lethal effects have been reported, but they are not always reproducible, possibly due to the concentration of the copper molecule or the method of contact with the mollusc. Previously, we demonstrated that the copper hydroxide fungicide functioned as a repellent and feeding deterrent for 4 mollusc species (Capinera & Dickens 2016). Results of the current study reported herein provided the same responses for the snail Z. provisoria under laboratory conditions.…”

“…Previously, we reported that copper hydroxide fungicide significantly suppressed foliage consumption by 4 mollusc species in choice and no-choice laboratory tests (Capinera & Dickens 2016). Copper hydroxide also has been reported to function as a repellent in laboratory bioassays against Leidyula floridana (Binney, 1851) (Gastropoda: Veronicellidae).…”

Repellents and feeding deterrents are underutilized tactics for plant pest damage suppression. Here I report on laboratory and screenhouse studies that assessed a copper hydroxide-based fungicide as a chemical barrier to prevent the Cuban brown snail, Zachrysia provisoria (Pfeiffer, 1858) (Gastropoda: Pleurodontidae) from accessing plants and from feeding on foliage. This snail species is considered to be one of the most important molluscs affecting plants in Florida. Studies were conducted as a follow-up to previous research with different molluscs that demonstrated the potential usefulness of copper hydroxide formulated in a commercial fungicide as a repellent. Although the residue of copper hydroxide displayed repellency to Z. provisoria in laboratory studies, it did not effectively prevent snails from climbing the sides of pots to access plants in screenhouses. Addition of 2 spreader-stickers, Bonide Turbo ® and Southern Ag ® , to the copper hydroxide to enhance retention of the fungicide did not improve performance. However, when copper hydroxide was applied to pots and foliage, feeding on vegetation was significantly suppressed under screenhouse conditions. I attribute these results to better fungicide residue persistence on foliage than on plastic pots.

“…At the same time, Cu acts as a broadspectrum biocide at higher concentrations due to its interaction with nucleic acids, disruption of enzyme active sites, interference with the energy transport system, and finally the disruption of the integrity of cell membranes (Fleming and Trevors 1989). A number of inorganic Cu formulations have been developed and used as biocides to contain plant pathogenic bacteria, fungi, oomycetes and in some instances, invertebrates and algae (Schüder et al 2004;Capinera and Dickens 2016) (Table 1). In addition to the direct application on plants in the field, CBACs are also used for seed treatment to prevent infection of seedlings by plant pathogens (Carisse et al 2000;Verma et al 2011).…”

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.

“…It is estimated that around 85% of all plant diseases are fungal in nature. To combat fungi, farmers have been evolving their practices by using various types of chemical fungicides such as mancozeb, kitazin, copper hydroxide, and many others . However, fungi respond to the use of fungicides by developing resistance against the componds .…”

Recent advances in engineering lead to the fabrication of nanomaterials with unique properties targeted toward specific applications. The use of nanotechnology in agriculture, in particular for plant protection and production, is an under‐explored area in the research community. Fungal diseases are one of the leading causes of crop destruction and, in this context, the antifungal effect of nanoparticles of cobalt and nickel ferrite against phytopathogenic fungi is reported here. As a proof of concept, it is also shown how such nanoparticles can be used as fungicides in plants. The developed cobalt and nickel ferrite nanoparticles (CoFe 2 O 4 and NiFe 2 O 4 ) are successfully tested for antimycotic activity against three plant‐pathogenic fungi: Fusarium oxysporum, Colletotrichum gloeosporioides , and Dematophora necatrix . In addition, it is also observed that these ferrite nanoparticles reduce the incidence of Fusarium wilt in capsicum. The study suggests that nanoparticles of CoFe 2 O 4 and NiFe 2 O 4 can be used as an effective fungicide in plant disease management.
