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.

Green Nanopesticide: pH-Responsive Eco-Friendly Pillar[5]arene-Modified Selenium Nanoparticles for Smart Delivery of Carbendazim to Suppress Sclerotinia Diseases

ACS Applied Materials & Interfaces, Journal Year: 2023, Volume and Issue: 15(13), P. 16448 - 16459

Published: March 21, 2023

Controlled-release delivery systems have been widely used to improve the efficacy and bioavailability of pesticides minimize environmental risks. Herein, a fungicide carbendazim (CBZ)-loaded, kind nanovalve including trimethylammoniumpillar[5]arene (AP5), methyl orange (MO)-functionalized mesoporous selenium (MSe) nanopesticides (CBZ@AP5/MSe⊃MO) were prepared. The endowed CBZ@AP5/MSe⊃MO with pH-responsive property, so can respond microenvironment pathogen Sclerotinia sclerotiorum (S. sclerotiorum). First, MO was shed due protonation, AP5-functionalized MSe gradually dissolved in an acid environment. Finally, CBZ released rapidly. It is reported that AP5 as host guest functionalized never applied agriculture. In vitro release experiments showed cumulative rate at pH 4.5 1.74 times higher than neutral addition, we found contact angle maize rape leaves effectively decreased, which could retain more after washout. also decrease dry biomass reducing sugar S.sclerotiorum. holds good safety profile for plants, animal cells, environment owing targeted properties. These results suggest environmentally friendly effective drug-loaded system against S. sclerotiorum. provides new strategy design development control
