Their incidence has increased over last two decades, mainly after ban of sodium arsenate, carbendazim, benomyl early 2000s. Since then, considerable efforts have been made to find alternative approaches manage these limit their propagation. Biocontrol is a sustainable approach fight against GTD-associated several microbiological control agents tested at least one pathogens involved diseases.

The Clonostachys genus is a saprophytic soil microfungus (Ascomycota). It exhibits significant ecological adaptability and plays crucial role in maintaining the balance of microorganisms. Species within this are natural antagonists insects nematodes, they also combat phytopathogenic fungi through mycoparasitism. This process involves producing lytic enzymes competing for space nutrients. species effective biocontrol agents agriculture have been utilized to manage pests affecting many high-value commercial crops, acting as biopesticide. They inhabit plant tissues, boosting defenses activating genes water nutrient uptake, enhancing performance. Additionally, produce bioactive metabolites with antimicrobial, antifungal, nematocidal, anticancer, antioxidant properties. can degrade plastic waste remove hydrocarbons from crude oil-contaminated sites when functioning endophytes, positioning promising candidate reducing environmental pollution. There still challenges limitations, such continuous surveillance safety on plants, establishment applications, formulation viability, variability due field conditions. These issues will be addressed. review provides an overview ecology, morphology, classification, biotechnological emphasizing its significance various fields.

Prevention of fungal diseases caused by Fusarium species, including F. culmorum, and thus the accumulation mycotoxins in wheat ears, is a constant challenge focused on development new, effective crop management solutions. One currently most ecologically attractive approaches biological control using natural antagonistic microorganisms. With this mind, potential thirty-three Clonostachys Trichoderma strains was assessed work. Screening tests were carried out vitro cultures, observed selected verified field semi-field experiments with two forms wheat: winter cv. Legenda spring Bombona. Three strains, namely C. rosea AN291, T. atroviride AN240 viride AN430 reported to be inhibiting growth culmorum KF846 synthesis DON, 3AcDON ZEN under both laboratory semi-controlled conditions. Observations contact zones tested fungi dual cultures exposed their mycoparasitic abilities against KF846. In addition, studies liquid have demonstrated ability these eliminate toxins. Meanwhile, AN35 cremeum AN392 used as soil inoculants experiment showed different effect content toxins ears (grains chaffs), while improved yield parameters, mainly grain health cultivars. It concluded that high reduce adverse effects ear infection; therefore, they can further considered context biocontrol factors improvers.

Fungi colonizing plants are gaining attention because of their ability to promote plant growth and suppress pathogens. While most studies focus on endosymbionts from grasses legumes, the large diverse group ericaceous has been much neglected. We recently described one very few fungal endophytes promoting Ericaceae Vaccinium macrocarpon (American cranberry), notably Codinaeella isolate EC4. Here, we show that EC4 also suppresses pathogens, which makes it a promising endophyte for sustainable cranberry cultivation. By dual-culture assays agar plates, tested potential suppression (or biocontrol) other microbes, 12 pathogenic fungi oomycete reported infect not only but blueberry, strawberry, tomato plants, rose bushes olive trees. Under greenhouse conditions, protects plantlets infected with notorious cranberry-plant Diaporthe vaccinii , known cause upright dieback berry rot.

The worldwide occurrence of wheat crown rot, predominantly caused by the pathogen Fusarium pseudograminearum, has a serious impact on production. Numerous microorganisms have been employed as biocontrol agents, exhibiting effectiveness in addressing wide array plant pathogens through various pathways. mycelium white-rot fungus Phanerochaete chrysosporium effectively inhibits growth F. pseudograminearum tightly attaching to it and forming specialized penetrating structures. This process leads release intracellular inclusions eventual disintegration cells. Furthermore, volatile organic compounds fermentation products produced P. exhibit antifungal properties. A comprehensive understanding mechanisms modalities action will facilitate advancement implementation this fungus. In order gain deeper mycoparasitic behavior chrysosporium, transcriptome analyses were conducted examine interactions between at 36, 48, 84 h. During mycoparasitism, up-regulation differentially expressed genes (DEGs) encoding fungal cell-wall-degrading enzymes (CWDEs), iron ion binding, mycotoxins mainly observed. Moreover, pot experiments revealed that not only promoted quality but also hindered colonization seedlings. led delay development stem base reduction disease severity incidence, activation plant’s self-defense mechanisms. Our study provides important insights into against rot pseudograminearum.

Pathogens obtained from naturally Esca-affected ‘Nero di Troia’ vines cropped in Grumo Appula (Puglia region, Southern Italy). antagonistic activity of each challenge organism was verified a dual culture. TH PO completely overgrew the three pathogens. Partial replacement characterized PE-FM, PE-PM, PE-PC AA-PC interactions. Deadlock at mycelial contact observed AA-FM AA-PM cultures. calculated antagonism index (AI) indicated PE moderately active antagonists (10 < AI 15), while AA weakly (AI 10). maximum value re-isolation (s) associated with deadlock among AA-PM, PE-FM always re-isolated when replaced confirmed their efficiencies inoculated on detached canes combination FM, PC PM.
