Опубликована: Янв. 27, 2025

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.

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.

Опубликована: Окт. 18, 2023

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. This review focuses on recent developments isolation, identification, preservation, substrates, consortium, quality control, mass production, field performance, registration, commercialization formulations strategic development next-generation multifunctional biological

Опубликована: Янв. 28, 2024

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). The effects treatments FOC biocontrol studied under growth chamber conditions. results showed that Şampiyon most resistant, while Gence to disease. colonization rates (8.91–24%), spore densities (16.4–50.4 spore/10 g soil), extent which a plant needs mycorrhizal conditions grow its maximum potential (i.e., dependencies—18.3–51.9%) recorded by treatment. Both single combined applications suppressed FOC. Suppressive more pronounced when used alone (when used, severity decreased 90 68%, p < 0.05). also best promotion phosphorus content release. indicate an interesting use in management onions.

Trichoderma application methods differentially affect the tomato growth, rhizomicrobiome, and rhizosphere soil suppressiveness against Fusarium oxysporum

Trichoderma spp. are widely used to enhance crop growth and suppress diverse diseases. However, inconsistent field efficacy remains a major barrier their use as reliable alternative synthetic pesticides. Various strategies have been investigated the robustness of application. Here, we evaluated how T. virens application methods (pre-, at-, post-transplant) affect two tomato varieties rhizosphere fungal bacterial communities. Although greatest abundance was observed in post-transplant application, at-transplant promoted most, indicating that greater does not necessarily result better growth. None significantly altered global communities tested varieties. Changes specific microbial genera guilds may underpin enhanced We also whether resulting microbiome changes mycelial conidial germination Fusarium oxysporum f. sp. lycopersici F. radicis-lycopersici , soilborne pathogens tomato, upon exposure volatile compounds emitted by culturable microbes metabolites extracted from soils after treatments. Volatile produced cultured suppressed both than those other Similarly, water-soluble soil samples most effectively rate spores. Overall, our results suggest is advantageous for promoting building suppressiveness against fusaria. further studies needed before applying this method support production. discuss critical future questions.

A new bacterial consortia for management of Fusarium head blight in wheat

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Май 2, 2024

Abstract Fusarium head blight (FHB) is a significantly important disease in cereals primarily caused by species. FHB control largely executed through chemical strategies, which are costlier to sustainable wheat production, resulting leaning towards sources such as resistance breeding and biological methods for FHB. The present investigation was aimed at evaluating newly identified bacterial consortium (BCM) biocontrol agents understanding the morpho-physiological traits associated with of spring wheat. Preliminary evaluation antagonistic plate assay vivo assessment indicated that BCM effectively inhibited growth wheat, reducing area under progress curve (AUDPC) deoxynivalenol (DON), potentially causing type II V resistance, improving single spike yield (SSPY). Endurance infection application better sustenance photosynthetic performance light energy harvesting its utilization. Correlation path-coefficient analysis maximum quantum (QY_max) directly influencing improvement SSPY reduction grain DON accumulation, corroborated principal component analysis. chlorophyll fluorescence might be applied phenotyping tool large-scale identification sensitivity

Trichoderma: A Review of Its Mechanisms of Action in Plant Disease Control

Trichoderma has been widely studied for its potential as a biocontrol agent against plant pathogenic organisms. Trichoderma&#039;s biological control mechanisms include competition, modification of environmental conditions, antibiosis, induction defensive mechanisms, and mycoparasitism. species are known to produce variety secondary metabolites that have antifungal activity. These peptaibols, gliotoxin, trichokonins. also produces chitinases β-1,3-glucanases can degrade the cell walls fungal pathogens. In addition direct antagonism pathogens, induce systemic or localised resistance in plants, which is achieved through production elicitors such chitin oligosaccharides β-glucans activate defence responses. form mutualistic associations with plants. these associations, colonises roots plants promotes growth by increasing nutrient uptake inducing resistance.
