Nanobiopesticides in sustainable agriculture: developments, challenges, and perspectives

Abstract

The environmental friendly nanomaterials with biodegradable, responsive and biocompatible properties have attracted considerable interest to explore safe and efficient pesticides, and applying nanotechnology to develop new nanopesticide formulations would avoid...

Biopesticides as a promising alternative to synthetic pesticides: A case for microbial pesticides, phytopesticides, and nanobiopesticides

“…Generally, nanoparticles can be produced from chemical or biological agents (mainly plants or microbes; Omole et al, 2018 ). Nanoparticles of biological origins that are used as pesticides are termed nanobiopesticides and are also very important as plant protectants ( Pan et al, 2023 ). Nanobiopesticides have found application as pesticidal agents in agriculture because of their excellent physicochemical characteristics like size, reactivity, surface area, and so on.…”

“…Nanobiopesticides have found application as pesticidal agents in agriculture because of their excellent physicochemical characteristics like size, reactivity, surface area, and so on. Besides, nanobiopesticides have unambiguous biological interactions with plants, as well as clear transport and fate in the environment ( Bratovcic et al, 2021 ; Kumar et al, 2022 ; Pan et al, 2023 ).…”

“…Nanobiopesticides can be defined as biological protection products that are developed using nanotechnology to enhance efficacy and reduce an environmental load of pesticides ( Chaudhary et al, 2021b , d ). Nanobiopesticides are formulated from nanomaterials and applied specially fixed on a hybrid substrate, encapsulated in a matrix or functionalized nanocarriers for external stimuli or enzyme-mediated triggers ( Agostini et al, 2012 ; Khati et al, 2018 ; Kumari et al, 2020 ; Agri et al, 2021 , 2022 ; Chaudhary et al, 2022 ; Pan et al, 2023 ). They are nanostructures with two or three dimensions used for carrying agrochemical ingredients and can help increase water solubility and bioavailability, and protect agrochemicals against environmental degradation.…”

“…Biopesticides are cheap, environment-friendly, specific in their mode of action, sustainable, do not leave residues, and are not associated with the release of greenhouse gases ( Borges et al, 2021 ). These biopesticides can be in the form of phytopesticides (plant origin; Idris et al, 2022 ), microbial pesticides (microbial origin; Harish et al, 2021 ), and nanobiopesticides (nanoparticles produced from biological agents; Abdollahdokht et al, 2022 ; Pan et al, 2023 ). Unlike synthetic pesticides, microbial pesticides are specific in action, can be easily sourced without the need for expensive chemicals, and are environmentally sustainable without residual effects ( Harish et al, 2021 ; Hummadi et al, 2021 ).…”

“…Phytopesticides have myriad of phytochemical compounds that make them exhibit various mechanisms of action, likewise, they are not associated with the release of greenhouse gases and are of lesser risks to human health compared to the available synthetic pesticides ( Malahlela et al, 2021 ; Idris et al, 2022 ). Nanobiopesticides have higher pesticidal activity, targeted or controlled release with top-notch biocompatibility, and biodegradability compared to the synthetic pesticides ( Abdollahdokht et al, 2022 ; Pan et al, 2023 ). Biopesticides act through different mechanisms, which include the inhibition and destruction of the plasma membrane and protein translation of pathogens/pests.…”
