“…Tu et al evaluated the inhibitory activity of distinct EOs encapsulated within alginate–chitosan microcapsules against five species of Ralstonia solanacearum (GIM1.71, GIM1.74, GIM1.76, GMI1000, and RS-5), a soilborne pathogenic bacterium responsible for vascular wilt disease in more than 200 different crop species . Ten EOs (from camphor, bay, artemisia, lavender, peppermint, cinnamon, lemon, lemon amine, anise-star, and tea tree) were encapsulated within alginate–chitosan microcapsules, with average particle sizes of 870.4 μm by a complex coacervation method.…”

Biological plant protection agents (BPPAs) are proposed as sustainable alternatives to chemical-based pesticides to face threats caused by pests and diseases emerging due to climate change. The present Review was conducted to identify the most promising materials to encapsulate and deliver BPPAs for pest and disease control with improved efficacy, increased systemic activity, and lower environmental impact. Searches on Scopus and Web of Science databases from inception up to June 30, 2022, revealed a total of 98 reports that met the eligibility criteria, 45% of which described the use of (1) naturally sourced polymers, such as chitosan (36%), alginate (23%) and plant-based proteins (16%); (2) synthetic polymers (35%); (3) inorganic materials (19%); and (4) microorganisms (1%). The review confirmed that micro- and nanoencapsulation of BPPAs using carrier materials of marine/terrestrial/synthetic sources should provide the agricultural community access to safer and more sustainable plant protection products.

“…Among the biotic stresses, bacterial wilt disease caused by Ralstonia solanacearum poses a significant threat to tomato cultivation, leading to devastating effects (Artal et al., 2012; Yuliar et al., 2015). This disease has become a major constraint for tomato growers worldwide with yield losses estimated to range from 35% to 90% in India alone (Gupta & Kamalachandran, 2018). In fact, R. solanacearum is ranked as the second‐most important bacterial plant pathogen globally in terms of scientific and economic significance (Balamurugan et al., 2020).…”

Pseudomonads produce a wide array of antimicrobial compounds including 2,4‐diacetylphloroglucinol (DAPG), which possess a broad‐spectrum antagonistic effect against phytopathogens. Rhizospheric soil samples were collected from the Solanaceous crops for isolation of fluorescent pseudomonads (FPs). Out of the 32 fluorescent bacterial isolates, 21 showed antagonistic activity against Ralstonia solanacearum (NAIMCC‐B‐01630) with the highest zone of inhibition at 38.33 mm. Among them, 11 bacterial isolates depicted the production of DAPG in Kings' B medium. DAPG production was detected by TLC and quantified through HPLC analysis. Moreover, the bacterial isolate OD13 exhibited higher DAPG production. Further, the presence of the DAPG‐encoding phlD gene within the size of 629 bp and 725 bp was also validated through amplification. These bacterial isolates belonged to the genera Pseudomonas as confirmed by morpho‐physiological characterization using the VITEK 2 system. The higher DAPG‐producing bacterial isolate was identified as Pseudomonas aeruginosa by polyphasic approach with GenBank accession number OQ781265. Thus, the DAPG‐producing rhizospheric Pseudomonas strains can be used as biocontrol agents for bacterial wilt. However, field study is highly essential before its successful application.
