Potential Strategies in the Biopesticide Formulations: A Bibliometric Analysis

Abstract

Biopesticides are pest and pathogen management agents based on living microorganisms or natural products (botanical origin). Due to their natural origins, they stand out as an environmentally friendly tool, since they quickly decompose and minimize pollution problems produced by synthetic pesticides. However, these products present significant challenges that affect the bioactivities of the active components, due to the degradation of the biomass or bioactive metabolite by factors such as air, light, and temperature. Therefore, in this study, a systematic search of the Scopus database was conducted and scientometric tools were used to evaluate formulation techniques and approaches that seek to improve the bioactivities of natural preparations. The results showed that published research on biopesticides has significantly increased by 71.24% in the last decade (2011–2021). Likewise, the bibliometrics showed, through temporal flow analysis, and in the period from 2010 to 2021, investigations evolved have toward the use of nanotechnology, with the purpose of improving and potentiating the formulations of biopesticides. Consequently, nanotechnology tools can be classified as current strategies of interest that allow the increase and protection of bioefficacy to a greater extent than traditional biopesticide preparations. This review constitutes an important contribution to future research and expands the panorama in relation to biopesticide formulations for the control of agricultural pests.

Advances in the Development of Biofertilizers and Biostimulants from Microalgae

“…W/O are of interest because the oil traps water, which delays evaporation, and the contact time of the active ingredient increases [ 41 ]. In the case of O/W, they are a type of emulsion that prevents the degradation of molecules without affecting biological activity; this is because it combines the protection provided by the hydrophobic environments created within the droplets with the greatest dispersion of metabolites in an aqueous medium [ 40 , 42 ]. Furthermore, these emulsions are environmentally friendly, less toxic to plants, and scalable in industrial processes [ 43 ].…”

“…On the other hand, encapsulation can be defined as the process in which a substance (active agent and core) is trapped and totally or partially covered by a carrier material (encapsulating agent), called a wall material, capsule, membrane, shell, matrix, or external phase, to form a system of particles [ 40 , 47 ]. This technique is used to encapsulate solid, liquid, or gaseous compounds with small particle sizes that can range between 1 and 100 nm (nanoparticles) and between 100 nm and 1000 µm (microparticles) [ 48 , 49 , 50 ].…”

Allelopathy as a source of bioherbicides: challenges and prospects for sustainable agriculture

“…It is estimated that the agro-tech sector may encounter many difficulties in securing food production for the rapidly growing human population in the coming years. The world's population is expected to increase by 2 billion persons in the next 30 years, from 7.7 billion currently to 9.8 billion in 2050 (Hernandez-Tenorio et al 2022). Out of the United Nations' 17 sustainable development goals, the second goal focuses on agriculture, aiming for zero-hunger levels worldwide while also being sustainable over time (OECD/FAO 2022).…”

The Insecticidal Activity of Azadirachta indica Leaf Extract: Optimization of the Microencapsulation Process by Complex Coacervation

“…The use of sustainable and environmentally friendly strategies safely protects the crops [ 2 ]. Therefore, research efforts have been focused on biocontrol, particularly through the use of plant extracts [ 3 ].…”
