Journal of Nanobiotechnology, Journal Year: 2022, Volume and Issue: 20(1)

Published: Jan. 4, 2022

Nanomaterials (NMs) have received considerable attention in the field of agrochemicals due to their special properties, such as small particle size, surface structure, solubility and chemical composition. The application NMs nanotechnology dramatically overcomes defects conventional agrochemicals, including low bioavailability, easy photolysis, organic solvent pollution, etc. In this review, we describe advances pesticides fertilizers, which are two earliest most researched areas agrochemicals. Besides, article concerns with new applications other bio-pesticides, nucleic acid pesticides, plant growth regulators (PGRs), pheromone. We also discuss challenges industrialization trend Constructing nano-agrochemical delivery system via facilitates improvement stability dispersion active ingredients, promotes precise reduces residual pollution decreases labor cost different scenarios, is potential maintain sustainability agricultural systems improve food security by increasing efficacy inputs.

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

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: Feb. 16, 2023

Over the years, synthetic pesticides like herbicides, algicides, miticides, bactericides, fumigants, termiticides, repellents, insecticides, molluscicides, nematicides, and pheromones have been used to improve crop yield. When are used, over-application excess discharge into water bodies during rainfall often lead death of fish other aquatic life. Even when fishes still live, their consumption by humans may biomagnification chemicals in body system can cause deadly diseases, such as cancer, kidney diabetes, liver dysfunction, eczema, neurological destruction, cardiovascular so on. Equally, harm soil texture, microbes, animals, plants. The dangers associated with use necessitated need for alternative organic (biopesticides), which cheaper, environment friendly, sustainable. Biopesticides be sourced from microbes (e.g., metabolites), plants exudates, essential oil, extracts bark, root, leaves), nanoparticles biological origin silver gold nanoparticles). Unlike pesticides, microbial specific action, easily without expensive chemicals, environmentally sustainable residual effects. Phytopesticides myriad phytochemical compounds that make them exhibit various mechanisms likewise, they not release greenhouse gases lesser risks human health compared available pesticides. Nanobiopesticides higher pesticidal activity, targeted or controlled top-notch biocompatibility biodegradability. In this review, we examined different types merits, demerits biopesticides, but more importantly, x-rayed appropriate approaches acceptability commercial usage phytopesticides, nanobiopesticides plant nutrition, protection/yield, animal/human promotion, possible incorporation integrated pest management system.
