Biological Control, Год журнала: 2024, Номер 188, С. 105439 - 105439

Опубликована: Янв. 1, 2024

Beneficial microbes play crucial role in modern agriculture, serving as biopesticides, biostimulants/biofertilizers, and mitigating abiotic stress crops. Their multifaceted functions contribute significantly to crop health sustainability, aligning with the principles of regenerative agriculture by minimizing carbon footprints reducing dependence on agrichemical inputs. The concept 'microbial consortia', involving combination multiple fungal bacterial species or strains, has gained recognition for its potential advantages over single species/strains applications. This method aims employ a spectrum ecological functions, encouraging biological equilibrium within agricultural systems. Recent research highlights how microbial consortia can directly indirectly enhance plant health, through various mechanisms interactions their host plants. review presents examples demonstrating efficacy biopesticides biostimulants/biofertilizers. These exhibit managing diseases pests, while also promoting growth specific biotic stresses examines real-world considering instances success failure, discusses methodologies employed evaluating interactions, addresses challenges selection, production, application optimal use providing valuable insights current future prospects agriculture.

Trichoderma atroviride seed dressing influenced the fungal community and pathogenic fungi in the wheat rhizosphere

Scientific Reports, Год журнала: 2022, Номер 12(1)

Опубликована: Июнь 11, 2022

Abstract Fusarium crown rot and wheat sharp eyespot are major soil-borne diseases of wheat, causing serious losses to yield in China. We applied high-throughput sequencing combined with qPCR determine the effect winter seed dressing, either Trichoderma atroviride HB20111 spore suspension or a chemical fungicide consisting 6% tebuconazole, on fungal community composition absolute content pathogens pseudograminearum Rhizoctonia cerealis rhizosphere at 180 days after planting. The results showed that significantly reduced amount F. soil ( p < 0.05), also changed structure community. In addition, field disease investigation measurement T. treatment whiteheads an average control 60.1%, 14.9% higher than treatment; increased by 7.7%, which was slightly more treatment. Therefore, found have potential replace fungicides extended range improve yield.

Assessment of Tunisian Trichoderma Isolates on Wheat Seed Germination, Seedling Growth and Fusarium Seedling Blight Suppression

Microorganisms, Год журнала: 2023, Номер 11(6), С. 1512 - 1512

Beneficial microorganisms, including members of the Trichoderma genus, are known for their ability to promote plant growth and disease resistance, as well being alternatives synthetic inputs in agriculture. In this study, 111 strains were isolated from rhizospheric soil Florence Aurore, an ancient wheat variety that was cultivated organic farming system Tunisia. A preliminary ITS analysis allowed us cluster these isolates into three main groups, T. harzianum (74 isolates), lixii (16 isolates) sp. (21 represented by six different species. Their multi-locus (tef1, translation elongation factor 1; rpb2, RNA polymerase B) identified afroharzianum, one lixii, atrobrunneum lentinulae These new selected determine suitability promoters (PGP) biocontrol agents (BCA) against Fusarium seedling blight (FSB) caused culmorum. All exhibited PGP abilities correlated ammonia indole-like compound production. terms activity, all inhibited development F. culmorum vitro, which is linked production lytic enzymes, diffusible volatile compounds.

Establishment of Biocontrol Agents and Their Impact on Rhizosphere Microbiome and Induced Grapevine Defenses Are Highly Soil-Dependent

Phytobiomes Journal, Год журнала: 2023, Номер 8(2), С. 111 - 127

Опубликована: Ноя. 7, 2023

With a reduction in available chemical treatments, there is an increased interest biological control of grapevine trunk diseases. Few studies have investigated the impact introducing beneficial microorganisms rhizosphere on existing indigenous soil microbiome. In this study, we explored effect two biocontrol agents (BCAs), Trichoderma atroviride SC1 (Ta SC1) (Vintec; Certis Belchim) and Bacillus subtilis PTA-271 (Bs PTA-271), bacterial fungal microbiome as well plant defense expression using high-throughput amplicon sequencing quantitative real-time polymerase chain reaction (PCR), respectively. Additionally, quantified both Ta Bs over time droplet digital PCR. The was more affected by factors such type, BCA treatment, sampling compared with Specifically, application produced negative impacts diversity, whereas BCAs did not affect diversity. Interestingly, survival establishment showed opposite trends depending indicating that physicochemical properties soils role establishment. Fungal co-occurrence networks were less complex than but highly impacted application. Soils treated presented stable networks, higher number positive correlations. Induced defenses also differed according to soil, being inoculation sandy soil. findings research emphasize relationships among highlight significance taking into account various factors, time, their influence structure dynamics microbial communities.

Effects of Trichoderma harzianum and Arthrobacter ureafaciens on control of Fusarium crown rot and microbial communities in wheat root-zone soil

Phytopathology Research, Год журнала: 2025, Номер 7(1)

Опубликована: Май 15, 2025

Abstract Biocontrol by inoculation with beneficial microbes is a proven strategy for reducing the negative effect of soil-borne pathogens. The effects Trichoderma harzianum LTR-2 and Arthrobacter ureafaciens DnL1-1 on Fusarium crown rot (FCR) disease influencing microbial community structure in wheat root-zone were evaluated plot experiment. experimental design consisted four treatments: (1) control, (2) pseudograminearum Fp (FP), (3) F. + (LFP), (4) (HFP). results showed that seeds coated spore suspension combination had relative control efficacies 50.77% 67.73% FCR disease, increased yield 58.32% 64.19%, respectively. Illumina MiSeq sequencing revealed bacterial fungal abundance diversity significantly higher ( P < 0.05) both treatment groups (HFP LFP) than FP groups. Principal coordinates analyses communities distinctly separated among Fungal composition analysis demonstrated phytopathogenic fungi Alternaria , Cladosporium decreased Mortierella Gamsia was more enriched HFP LFP group. Bacterial microbes, such as Bacillus Streptomyces abundant LEfSe indicated key different genera, e.g. Tetracladium (fungus), Sphingomonas Ramlibacter (bacteria), which negatively correlated TP treatment. It concluded application may recruit variety phosphate-solubilizing to promote growth. Overall, these confirm following alone combined accumulated easily compared

European Journal of Plant Pathology, Год журнала: 2023, Номер 167(4), С. 453 - 476

Опубликована: Сен. 8, 2023

Abstract Many Fusarium species cause serious diseases for cereal cultivation. These include head blight and crown rot on wheat bakanae disease rice. represent a major concern both in terms of food security safety. The latter is connected with the risk mycotoxin contamination grains. Biological control has proven its potential controlling cereals caused by number studies, indeed several commercial products are under development. We review current knowledge mechanisms underlying biological focus fungal biocontrol agents, also challenges related to co-occurrence species. Several established (antibiosis, competition, hyperparasitism induced resistance) can act simultaneously, thus resulting and, consequently, reduction contamination. roles some many mycotoxins produced species, which they detoxified enzymes or other fungi how agents (BCAs) stimulate their degradation. Finally, effect resident microbiota, as well microbiota performances BCAs, discussed. New perspectives use management cereals.
