“…The above results were consistent with literature [62,63]. Nanopesticides could be more potent than conventional pesticide formulations against harmful target organisms, due to their larger specific surface area which could increase the adsorption and accumulation of the active ingredient by the pest [64,65].…”

The solid nanodispersion of 15% emamectin benzoate was prepared by the method of solidifying nanoemulsion. The mean particle size and polydispersity index of the solid nanodispersions were 96.6 ± 1.7 nm and 0.352 ± 0.041, respectively. The high zeta potential value of 31.3 ± 0.5 mV and stable crystalline state of the nanoparticles suggested the excellent physical and chemical stabilities. The contact angle and retention compared with microemulsions and water dispersible granules on rice, cabbage, and cucumber leaves indicated its improved wettability and adhesion properties. The bioassay compared with microemulsions and water dispersible granules against diamondback moths and green peach aphids provided an evidence of its enhanced biological activity. This formulation composition could avoid organic solvents and obviously reduce surfactants. It is perspective in raising bioavailability and reducing residual pollution of pesticides and further improving agricultural production and environmental safety.

“…The poorly water soluble BP was formulated into water dispersible NP as reported earlier by Anjali et al (2010). Briefly, BP was dissolved in n-butyl acetate and to this, soybean lecithin with 92 % soybean phosphatidylcholine (SbPC), ammonium glycyrrhizinate (AG) and secondary butyl alcohol (SecButOH) were added to constitute the oil phase.…”

“…To combat the resistance, application of a higher dosage of pesticide along with its toxic solubilizers (Wright et al 1982) has elevated the pesticide pollution and environmental toxicity (Figà-Talamanca et al 2001). In accordance, poorly water-soluble Bulk permethrin (BP) was formulated into hydrodispersible nanometric form by rapid evaporation of pesticideloaded oil-in-water (O/W) microemulsion (Anjali et al 2010). The obtained Nanopermethrin (NP) was freely dispersive in water with improved stability and target specificity.…”

Permethrin, a poorly water-soluble synthetic pesticide belonging to the pyrethroid family, was formulated into water-dispersive nanometric form by rapid evaporation of pesticide loaded oil-in-water microemulsion. The mean hydrodynamic diameter of Nanopermethrin was found to be 199.01 ± 1.4 nm. The efficacy of the Nanopermethrin was comparatively investigated with its bulk form against 2-3 days old adult mosquitoes by WHO cone bioassay for 60 min. The median knockdown concentration of Culex tritaeniorhynchus, Culex quinquefasciatus and Aedes albopictus were found to be 7.20 × 10(4), 7.53 × 10(4), 0.42 × 10(3) mg/L for Bulk permethrin, and 0.98 × 10(4), 1.17 × 10(4), 0.05 × 10(3) mg/L for Nanopermethrin, respectively. The obtained results extrapolate the improved efficacy of Nanopermethrin even at low-level concentrations. Hence, the formulated Nanopermethrin will serve as an effective alternative pesticide in controlling the mosquito population with reduced environmental toxicity.

“…Some of the nanopesticides and herbicides are available as water-or oil-based nanoemulsions having uniform suspension of pesticide or herbicide which can be mixed with gels, creams, liquids, etc. Generally neem oil (Anjali et al 2010 ;Jerobin et al 2012 ;Xu et al 2010 ), garlic essential oil (Yang et al 2009 ), Artemisia arborescens L essential oil (Lai et al 2006 ) and Lippia sidoides oil (Abreu et al 2012 ) are used as target substances. Various scientists suggested use of nanodelivery systems for pheromones (Bhagat et al 2013 ;Hellmann et al 2011 ), capsaicin from chili peppers (Bohua and Ziyong 2011 ) and Lansiumamide B extract from the seeds of Clausena lansium (Yin et al 2012 ).…”

Agri-nanotechnology has the potential to transform the agricultural practices. Nanoparticles of interest can be produced both by various physical and chemical methods. The biogenetic production of nanoparticles is now of high interest due to simplicity of the procedures and their versatility. Several species of bacteria and plants are able to synthesize nanoparticles or help in the process of their production. Implementation of nanoparticlebased smart delivery system and nanosensors holds the promise of controlled release of agrochemicals and site-targeted delivery of various macromolecules needed for improved plant disease resistance, effi cient nutrient utilization and improved plant defence in an environment-friendly manner. Nanoparticle-mediated plant transformation has the potential for genetic modifi cation of plant improvement.
