Fusarium oxysporum is a destructive plant pathogen with robust survival mechanisms, complicating control efforts. This study aimed to develop nanoformulated fungicides, screen antagonistic bacteria, and evaluate their combined efficacy. A novel self-emulsifying nanoemulsion (DZW) was formulated using zein benzaldehyde-modified wheat gluten (BgWG) as carriers for dimethachlon (DTN). The preparation process optimized material ratios emulsification techniques. Concurrently, bacterial strains against F. were screened via the plate standoff method, identifying Bacillus velezensis MLY71 both compatible DTN. DZW achieved particle size of 93.22 nm, an encapsulation efficiency (EE) 90.57%, DTN loading capacity (LC) 67.09%, sustained release over 96 h. combination (0.04 mg·mL⁻¹) B. (1 × 10⁴ CFU·mL⁻¹) 76.66% inhibition rate MLY127, 1.71 times greater than alone, indicating significant synergy. At concentration 0.20 mg·mL⁻¹, showed synergy coefficient 1.33. also observed in soil environments, its adaptability controlling soil-borne pathogens. As sustainable management continues gain attention agricultural disease control, this offers promising strategy achieving higher efficacy same fungicide dose or satisfactory reduced application. excellent drug-loading performance BgWG expanded applications by-product gluten.

Introduction The cotton aphid Aphis gossypii poses a global, serious threat to yield and quality. Although chemical pesticides are effective, pollution resistance increasingly prominent, making development of new biopesticides priority in the context green agricultural development. Methods Given that reports on activity surfactins against A. limited, here, 107 Bacillus strains isolated from extreme environment Chinese Taklamakan Desert were screened for insecticidal using leaf-dip method. Active characterized by morphological observation, 16S rRNA gene sequencing, phylogenetic analysis. Secondary metabolite synthesis genes identified whole-genome sequencing antiSMASH Results B. australimaris strain TRM82479 showed 75.00% 48-h mortality . An analysis this contains several clusters related nonribosomal peptide (NRP) fengycin lichenysin lipopeptide analogs. Cluster 1 has highest similarity 52% with cluster, 8 92% cluster. It is inferred can produce analogs distinct lichenysin, so we its NRPs. results surfactin main substance, an LC 50 0.857 mg/mL 95 4.350 aphids aqueous solution. zebrafish acute toxicity experiment low-toxic fish, indicating good biological safety. Discussion This study not only provides resources control but also demonstrates potential as biopesticides, laying foundation their future application.

Nicotiana tabacum possesses significant economic value and has been used medically recreationally due to its mildly irritating properties. In recent years, Corynespora cassiicola emerged as a major cause of yield losses in Chinese tobacco crops, yet effective control measures remain undeveloped. This present study characterised the morphological characteristics C. isolated from tobacco. For biocontrol purposes, strain (YZU 173039) exhibiting strong inhibitory effects on mycelium growth was identified, demonstrating an inhibition rate 66.0% vitro. identified Bacillus velezensis based features sequence analyses 16S rRNA gyrB gene. Not only did fermentation broth inhibit mycelial cassiicola, but volatile organic compounds (VOCs) also reduced melanin content downregulated expression genes associated with synthesis. Three scytalone dehydratase (SCD) family were predicted be potentially involved synthesis pathogenicity. Furthermore, found activate defence mechanisms tobacco, evidenced by changes plant defence-related enzymes (Phenylalanine Ammonia-lyase (PAL), peroxidase (POD), polyphenol oxidase (PPO)) levels three (NtAOS, NtMYC2a, NtJAZ1). Results greenhouse experiments indicated that could significantly reduce disease severity caused cassiicola. As promising agent, B. YZU 173039 potential occurrence spread leaf spot crops.

Bacillus halotolerans, a halophilic bacterial species of the genus Bacillus, is emerging as biological control agent with immense potential for sustainable agriculture, particularly in extreme conditions and environmental rehabilitation. This review summarizes current state research on B. emphasizing its diverse applications biocontrol plant pathogens, growth promotion under salinity stress, nematode management, bioremediation. halotolerans utilizes several mechanisms such production siderophores phytohormones, secretion exopolysaccharides, release antifungal nematicidal compounds, which allows it to mitigate both abiotic biotic stresses various crops, including wheat, rice, date palm, tomato, others. In addition, genomic metabolomic analyses have revealed secondary metabolite that improves antagonistic growth-promoting traits. Despite significant progress, challenges remain translating laboratory results into field applications. Future should focus formulating effective bioinoculants trials maximize practical utility agriculture resilience.
