“…Humans and animals as part of the environment can also be affected by the use of compounds that help control pests and plant diseases. Lin et al (2020) mention that the use of chemical fungicides in fruits or vegetables could modify the composition of the intestinal microbiota. Therefore, a more complete study is required on the application of wastewater in pest control, either as a direct application or compounds recovery of interest, considering the present economic-environmental impact.…”

Pests have a negative impact on the economy and the environment. There is an increased urgency for adequate pest control because many pests show high adaptation and climate change has created favorable circumstances for pests. For pest control, synthetic chemicals are used that are lethal to non-target organisms and are toxic to pollinators and aquatic invertebrates. Chemical compounds in plants and derivatives from lignocellulosic materials act against pests. The wastewater from lignocellulosic biomass is a potential source of new compounds with bactericidal, fungicidal, and pesticidal effects that have demonstrated inhibitory activity against plant pathogens. Fungicidal, nematicidal, insecticidal, larvicidal, and bactericidal activities have been proven. Inorganic and organic compounds, such as phenols, aldehydes, esters, and furanics, are the main ones identified. Due to the antimicrobial activity of wastewater, applying it to the soil can modify the composition and structure of key microbial communities. Deep research about richness, biodiversity, functionality, and microbials is needed. This review provides a comprehensive overview of wastewater types that have been applied and possible sources to obtain potential compounds for pest control. Moreover, associated active compounds, recovery techniques, and environmental impacts are reviewed.

“…In addition, pesticides are considered a powerful biological risk because they can persist in the environment for years (Sharma et al 2020). Chemical fungicides are widely used because they are effective in sterilizing (Lin et al 2020). However, they have also been reported to induce resistance in fungal plant pathogens (Swett et al 2020).…”

“…Fungicides are widely applied to control fungal pathogens on growing crops to improve yields (Cintia et al, 2021;Lin et al, 2020;Miller et al, 2021;Nermine et al, 2021;Patrick et al, 2021;Regueiro et al, 2015). Metrafenone (MF) is a new type of benzophenone derivative fungicide, which is a brand-new active ingredient in the field of phytochemical protection (structure in Fig.…”

Aqueous photodegradation of the benzophenone fungicide metrafenone: Carbon-bromine bond cleavage mechanism

et al. 2021

Metrafenone (MF), as a new type of benzophenone fungicide, has been widely used in agriculture and is persistent in the environment. Understanding its photochemical fate is essential for the comprehensive evaluation of its ecological risk.In the present work, we reported a detailed study on the photochemical transformation of MF in aqueous solution under irradiation (at λ > 290 nm using a high pressure mercury lamp). MF was relatively photo-reactive showing a low polychromatic quantum yield of photolysis (1.06×10 -4 ) counterbalanced by a significant light absorption above 290 nm. A series of photoproducts were identified by high resolution mass spectrometry (HR-MS) analysis, and three different pathways, including oxidation of the methyl group, debromination and replacement of bromine by hydroxyl group were proposed. Among them, debromination was identified as the dominating process that could be achieved via homolytic C-Br bond cleavage from singlet and triplet MF, as confirmed by laser flash photolysis (LFP) experiments and density functional theory (DFT) calculations. Toxicity assessment revealed that photochemical degradation reduced the ecotoxicity of MF efficiently. Nitrate ions and humic acid promoted the MF photolysis, while bicarbonate exhibited no effect.Results obtained in this work would increase our understanding on the environmental fate of MF in sunlit surface waters.

“…Persistent exposure to these toxic chemicals has since been associated with several human health (producers, workers, and consumers) ailments including potential weakening of homeostatic processes, immune disruption (Liamin et al, 2017) and even onset of cancers (J.

Increasing concerns toward food safety and public health have rendered the use of synthetic chemicals in agricultural environments unacceptable. A shift toward biologically safe approaches has been considered a preferred strategy within the food handling chain and has received increasing attention over the past years in managing undesirable microbial growth. Although several studies have looked at the mode of action of most antagonists,
