Trichoderma spp. are ubiquitous soil-borne fungi that widely used in biological control to promote and regulate healthy plant growth, as well protect against pathogens. However, with many materials, the relative instability of propagules limits its practical use industrial applications. Therefore, there has been significant research interest developing novel formulations various carrier substances compatible these fungal can enhance shelf-life overall efficacy Trichoderma. To this end, herein, we investigate a variety biopolymers nanoparticles for stabilization atrobrunneum T720 conidia control. The best-performing agents-agar cellulose nanocrystals (CNC)-were then preparation oil-in-water emulsions encapsulate T720. Emulsion properties including oil type, oil:water ratio, biopolymer/particle concentration were investigated respect emulsion stability, droplet size, viability over time. Overall, agar-based yielded highly stable small sizes, showing no evidence drastic creaming, or phase separation after 1 month storage. Moreover, able maintain ~ 100% conidial 3 months storage, 70% 6 months. We anticipate results demonstrated herein will lead new generation significantly improved KEY POINTS: • Various evaluated improving stability Oil water was prepared using agar interface stabilizers Agar-based showed encapsulated

Chickpea wilt caused by Fusarium oxysporum f. sp. ciceris (FOC) is one of the most prevalent and damaging diseases in chickpea-growing areas. To manage FOC an environmentally friendly sustainable manner, current studies were carried out 2023 2024, emulsion-based bioformulations two potential Trichoderma isolates, T. harzianum AMUTH-1 viride AMUTV-1 prepared tested under field conditions. For comparison, Pseudomonas fluorescens AMUPF-1, Grow-Power™ (commercial bioagent) fungicide (carbendazim) used as benchmarks. Field have shown that chickpea variety RVG-202 was highly susceptible to developed severe at vegetative stage. However, application bioformulation significantly reduced severity (55%) enhanced plant growth yield 23–33% 31%, respectively. The effect this emulsion formulation also par with fungicide, carbendazim commercial bioagent, Grow-Power™. Hence, may be considered alternative control measure for multi-pathogenic plants. This outcome could devise a suitable integrated management module safeguard plants from FOC.

The coating agent is critical in ensuring the success of seed biopriming. In this study, various biopolymers (sodium alginate, carboxymethylcellulose, gum arabic, xanthan gum) were tested for their efficacy as a bioagent (Trichoderma asperellum) bioprimed to Brassica rapa (pak choy) seeds. Seeds and first treated separately biopolymer solutions, examined germination spore viability, respectively, measure compatibility. suitable concentrations then used coat T. asperellum seeds, percentage entrapped, viable count determined reflect efficacy. with efficient was selected employed on radicle length determined. Results revealed that benefited Spore viability higher when all (89–100%) than without (84%). Higher achieved sodium alginate (1.5% w:v) which entrapped more spores during biopriming (83.63 ± 0.86%) retained (4.01 0.01 log seed-1) after 24 h post-priming. Biopolymers have no adverse effect germination, although increasing inhibited elongation. short, using 102 spores/mL therefore recommended seeds (90.67 2.88%) overall benefits can be achieved.
