ABSTRACT Bacillus velezensis SQR9 or Trichoderma harzianum NJAU4742‐amended bioorganic fertilizers might significantly improve the soil microbial community and crop yields. However, mechanisms these microorganisms act are far away from distinctness. We combined amplicon sequencing with culturable approaches to investigate effects of on pear tree growth, rhizosphere nutrients mechanisms. The T4742 treatments increased total biomass trees by 68% 84%, respectively, compared conventional organic fertilizer treatment (CK). tends increase matter available phosphorus, while more effectively enhances nitrogen, potassium, iron zinc levels.

Soilborne pathogens reduce 60% of the yield onion crops. A common fungal pathogen causing wilt disease and severe losses is Fusarium basal rot (FBR). In this study, combination Arbuscular Mycorrhizal Fungi (AMF) with Trichoderma harzianum was investigated against FBR. Onion samples were collected from Ankara–Polatlı region. Among isolates, isolate S6 identified as F. oxysporum f. sp. cepae (FOC) using morphological molecular methods pathogenicity tests. Different combinations AMF (Funneliformis mosseae pure strain commercial AMF) T. inoculated on susceptible cultivars (Seç, Gence, Şampiyon).

Trichoderma spp. has the ability to inhibit fungal plant pathogens through several mechanisms like production of hydrolytic enzymes, mycoparasitism, coiling, and antibiosis is therefore recommended as a potential native biocontrol agent for effective control soil-transmitted diseases. Various species Trichoderma, T. virens, asperellum, harzianum, etc., have been explored their activity against phytopathogens. There are different strains with respect pathogens. Efforts made develop efficient methods, such microencapsulation use polymers, adjuvants, or carriers, increase shelf-life efficacy formulations. The crucial aspects success include developing validating formulations, improvement in shelf-life, cost-effectiveness, easy accessibility, improved delivery systems, broad spectrum action, robust performance (biocontrol), integrative strategies sustainable disease management.

ABSTRACT Fungal seed‐ and soilborne diseases are economically devastating threats to global agriculture. The pathogenic fungi infiltrate seeds during production, storage, or planting persist within the soil, posing a significant challenge crop health yield. use of microbial consortia has become promising alternative for their management. In this study, 15 isolates (six fungal nine bacterial) were evaluated broad‐spectrum antagonistic activities against eight major pathogens, namely, Rhizoctonia solani (rice), Fusarium verticillioides (maize), Macrophomina phaseolina F . udum (redgram), oxysporum f. sp. ciceris (chickpea), Sclerotium rolfsii (groundnut), Aspergillus niger Alternaria sesami (sesame) under in vitro conditions. All showed variations inhibitory capabilities all pathogens. Evaluation plant growth‐promoting traits identified Trichoderma asperellum (Tricho1 Tricho2) Bacillus subtilis (B3, S4KB5 S8KB2) as most effective biocontrol isolates. three (MC1, MC2, MC3) developed using compatible potential reducing disease incidence promoting growth groundnut chickpea. consortium MC1 comprising Tricho1 + S8KB2 was both chickpea, which recorded lowest collar rot wilt 9.33% 8.33%, respectively. study consortia.

Abstract Background Wheat stem rust (WSR), caused by Puccinia graminis f. sp. tritici (Pgt), represents a significant threat to global wheat production. Biocontrol agents, such as Trichoderma harzianum HE22 (TH), offer sustainable strategies for managing this disease. This study evaluates the efficacy of TH cultured in potato dextrose broth (PDB) supplemented with various chemical inducers (TSDCIS), including potassium tartrate (T1), mixture micronutrients (T2), and thiamine (T3). These treatments were compared unmodified (T4) evaluate their potential controlling WSR at both seedling stage under field conditions, primary objective enhancing disease management while improving yield quality. Results Under greenhouse T1 significantly reduced severity 86.2% 77.7%, respectively, decreased area progress curve (AUDPC) 77.5% untreated control. also extended incubation latent periods, pustule density, mitigated oxidative damage. Biochemical analyses revealed elevated levels total phenols enhanced activity antioxidant enzymes, peroxidase (POD) polyphenol oxidase (PPO), along increased concentrations ascorbic acid proline. Additionally, lipid peroxidation, lowered H₂O₂ concentrations, minimized electrolyte leakage, demonstrating its protective effects on plant tissues. Microscopic using transmission electron microscopy (TEM) scanning (SEM) confirmed these effects. Treated plants exhibited intact cellular membranes, well-organized chloroplasts, integrity, whereas showed severe structural damage, plasmolysis distorted chloroplast morphology. Conclusion T. (T1) demonstrates an environmentally friendly highly effective strategy rust. approach not only reduces but enhances overall health, making it promising tool agricultural practices.

These peptaibols, gliotoxin, trichokonins. also β-1,3-glucanases chitinases can break down fungal pathogens’ cell walls. In addition to direct antagonism against pathogens, trigger localised or systemic resistance in plants, which is achieved through the production elicitors such chitin oligosaccharides β-glucans activate defence responses. form mutualistic associations with plants. colonises roots these partnerships, enhancing by boosting nutrient uptake triggering resistance.
