Abstract:Pesticides used in Korea are grouped by four classes of hazard (extremely, highly, moderately and slightly hazardous) based on acute oral and dermal toxicity in the rat. However, there is little information of carcinogenic effects. The aim of this study was to evaluate potential carcinogenicity for active ingredients of pesticides used in Korea. A total of 1,283 pesticide items were registered under the Pesticide Control Act of which 987 were commercially available. Of these 987 items, 360 active ingredients n… Show more
“…The modern farming market in the Asia–Pacific and Latin American regions has already reached a value of billions in USD [ 22 ]. It was estimated in 2009 that agriculture producers globally supply approximately USD 40 billion worth of pesticides annually, which are used to eliminate pest-related diseases worldwide [ 23 ]. The global use of pesticides significantly increased from 1990 to 2007, and this trend then changed after 2007 and 2014 [ 24 ].…”
This review delves into the mesmerizing technology of nano-agrochemicals, specifically pesticides and herbicides, and their potential to aid in the achievement of UN SDG 17, which aims to reduce hunger and poverty globally. The global market for conventional pesticides and herbicides is expected to reach USD 82.9 billion by 2027, growing 2.7% annually, with North America, Europe, and the Asia–Pacific region being the biggest markets. However, the extensive use of chemical pesticides has proven adverse effects on human health as well as the ecosystem. Therefore, the efficacy, mechanisms, and environmental impacts of conventional pesticides require sustainable alternatives for effective pest management. Undoubtedly, nano-agrochemicals have the potential to completely transform agriculture by increasing crop yields with reduced environmental contamination. The present review discusses the effectiveness and environmental impact of nanopesticides as promising strategies for sustainable agriculture. It provides a concise overview of green nano-agrochemical synthesis and agricultural applications, and the efficacy of nano-agrochemicals against pests including insects and weeds. Nano-agrochemical pesticides are investigated due to their unique size and exceptional performance advantages over conventional ones. Here, we have focused on the environmental risks and current state of nano-agrochemicals, emphasizing the need for further investigations. The review also draws the attention of agriculturists and stakeholders to the current trends of nanomaterial use in agriculture especially for reducing plant diseases and pests. A discussion of the pros and cons of nano-agrochemicals is paramount for their application in sustainable agriculture.

“…The triazoles 1-(4-chlorofenoxy)-3,3-dimethyl-1-(1H- 1,2,4-triazol-1-yl)butan-2-one (triadimefon®) (TDM) and 1-(4-chlorophenyl)-3-cyclopropyl-2-(1H-1,2,4-triazol-1-yl)butan-1-ol (cyproconazole®) (CPZ) (Fig. 1 ) are used to control B. cinerea in grapevine [ 12 – 14 ], but its use is widely questioned [ 15 – 17 ]. Fig.…”
Triadimefon (TDM) and cyproconazole (CPZ) are two triazoles widely used as fungicides. Several azoles were synthesised starting from commercial TDM and CPZ. The compounds were evaluated against phytopathogenic filamentous fungi, including Aspergillus fumigatus (AF), A. niger (AN), A. ustus (AU), A. japonicus (AJ), A. terreus (AT), Fusarium oxysporum and Botrytis cinerea isolated from grapevine in the province of San Juan, Argentina. Three of the synthesised compounds (1-(Biphenyl-4-yloxy)-3,3-dimethyl-1-(1H-1,2,4-triazol-1-yl)butan-2-one, 1; 2-(Biphenyl-4-yl)-3-cyclopropyl-1-(1H-1,2,4-triazol-1-yl)butan-2-ol, 3; 3-Cyclopropyl-2-(4’-fluorobiphenyl-4-yl)-1-(1H-1,2,4-triazol1-yl)butan-2-ol, 4) presented remarkable in vitro fungicidal properties, with better effects than TDM and CPZ on some of the target fungi. Cytotoxicity was assessed using human lung fibroblasts MRC5. Derivative 1, with IC50 values of 389.4 µM, was less toxic towards MRC-5 human lung fibroblasts than commercial TDM (248.5 µM) and CPZ (267.4 µM). Docking analysis and molecular dynamics simulations suggest that the compounds present the same interaction in the binding pocket of the CYP51B enzyme and with the same amino acids as CPZ. The derivatives investigated could be considered broad-spectrum but with some selectivity towards imperfect fungi.
