“…Hydrolyzed starch as an agent in encapsulating pesticides (metabolites produced by Bacillus thuringiensis) because it protects environmental factors and improves the formulated product. In addition, encapsulation can be efficient for the formulation of biofungicides, biopesticides, and/or biological fertilizers in agriculture (Do Nascimento Junior et al, 2021). Cell encapsulation in polysaccharide polymers such as alginate as a technique for ensuring the controlled incorporation of beneficial plant microorganisms into the soil.…”

Tea (Camellia sinensis L), is a popular agricultural product enjoyed by people around the world. Bio-fertilizers that use bacteria found in soil called endophytes, have proven effective for increasing growth and plant productivity. Endophite bacteria can also produce growth hormones such as auxins, ethylene, and cytokinins. This research aims to determine the effectiveness of auxin-producing endophytic bacterial microcapsules on tea growth. The research design used was a completely randomized design (CRD), 16 treatments with 2 replications. The first factor was immersion of endophite bacterial suspension consisting of S0 = 0 hours; S1 = 24 hours; S2 = 36 hours and S3 = 48 hours and the second factor was the addition of microcapsules consisting of I0 = 0 gr; I1 = 5 gr; I2 = 10 gr; I3 = 15 gr. Isolation from tea roots and stems obtained 6 isolates of endophite bacteria. Auxin test showed that the six isolates were able to produce auxin. Observation of plant height showed that the best treatment was in treatment I3 (17.04 cm). Observation of leaves amount was in treatment I3 (6.88 strands). For the leaf area parameter, the highest number was in the S1 treatment (22.8 cm2). For stem diameter parameter, highest data was in treatment I2 (1.69 mm). The test results showed that the application of suspension and endophite bacteria microcapsules significantly increased the growth of tea.

“…Otherwise, an increase in the use of natural polymers is seen, and non-hydrolyzed biopolymers have been widely used in agriculture due to their availability and low cost. Among them, hydrolyzed starches stand out as agents in the encapsulation of Bt pesticides (metabolites produced by Bacillus thuringiensis ) because they protected environmental factors and improvement in the formulated product [ 7 ]. Moreover, encapsulation can be efficient for formulations of biofungicides, biopesticides, and/or biofertilizers in agricultural fields, becoming an economically viable technique for farmers [ 12 ].…”

This review presents an updated scenario of findings and evolutions of encapsulation of bioactive compounds for food and agricultural applications. Many polymers have been reported as encapsulated agents, such as sodium alginate, gum Arabic, chitosan, cellulose and carboxymethylcellulose, pectin, Shellac, xanthan gum, zein, pullulan, maltodextrin, whey protein, galactomannan, modified starch, polycaprolactone, and sodium caseinate. The main encapsulation methods investigated in the study include both physical and chemical ones, such as freeze-drying, spray-drying, extrusion, coacervation, complexation, and supercritical anti-solvent drying. Consequently, in the food area, bioactive peptides, vitamins, essential oils, caffeine, plant extracts, fatty acids, flavonoids, carotenoids, and terpenes are the main compounds encapsulated. In the agricultural area, essential oils, lipids, phytotoxins, medicines, vaccines, hemoglobin, and microbial metabolites are the main compounds encapsulated. Most scientific investigations have one or more objectives, such as to improve the stability of formulated systems, increase the release time, retain and protect active properties, reduce lipid oxidation, maintain organoleptic properties, and present bioactivities even in extreme thermal, radiation, and pH conditions. Considering the increasing worldwide interest for biomolecules in modern and sustainable agriculture, encapsulation can be efficient for the formulation of biofungicides, biopesticides, bioherbicides, and biofertilizers. With this review, it is inferred that the current scenario indicates evolutions in the production methods by increasing the scales and the techno-economic feasibilities. The Technology Readiness Level (TRL) for most of the encapsulation methods is going beyond TRL 6, in which the knowledge gathered allows for having a functional prototype or a representative model of the encapsulation technologies presented in this review.

“…Encapsulation involves the active ingredient being enclosed within the polymer. The size of the capsule, which provides controlled release of the active ingredient after plant protection product application, varies from 2-50 µm, or 1-2 µm [91,92]. For encapsulation of microorganisms, various materials are used, including natural and synthetic polymers such as agar and agarose, starch, corn syrup, polyacrylamide, and polyurethane from artificial materials [93,94].…”

Plant protection in contemporary agriculture requires intensive pesticide application. Their use has enabled the increase in yields, simplifying cultivation systems and crop protection strategies, through successful control of harmful organisms. However, it has led to the accumulation of pesticides in agricultural products and the environment, contaminating the ecosystem and causing adverse health effects. Therefore, finding new possibilities for plant protection and effective control of pests without consequences for humans and the environment is imperative for agricultural production. The most important alternatives to the use of chemical plant protection products are biopesticides. However, in order to increase their application and availability, it is necessary to improve efficacy and stability through new active substances and improved formulations. This paper represents an overview of the recent knowledge in the field of biopesticides and discusses the possibilities of the use of some new active substances and the improvement of formulations.
