Item type:Publication, Antagonistic effects of Chaetomium globosum and Trichoderma viride against Chili Anthracnose(2026-01-01); The research demonstrated that Trichoderma viride and Chaetomium globosum inhibited Colletotrichum acutatum by 90.30% and 88.20%, respectively, primarily via competition for nutrients/space and parasitism, with no observed antibiosis. the field trials revealed that both fungi significantly reduced anthracnose severity. Trichoderma viride applications at 1, 2, and 3 g/L decreased disease incidence by 80.68%, 91.16%, and 92.27%, respectively, while Chaetomium globosum reduced it by 87.61–92.65%. Both exceeded synthetic fungicide Antracol (83.48–89.37% reduction) as a controlled treatment. Attack intensity followed a similar trend, with Trichoderma viride (95.12–97.46% suppression) and Chaetomium globosum (92.76–96.83%) surpassing Antracol (89.95–93.80%). Additionally, Trichoderma viride and Chaetomium globosum enhanced salicylic acid levels in chili plants, suggesting induced systemic resistance. These findings highlighted the potential of antagonistic fungi as sustainable biocontrol agents which would develop to be biofungicide, offering effective anthracnose management while reducing chemical residues. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Control of rice blast disease caused by Magnaporthe oryzae by application of antifungal nanomaterials from Emericella nidulans(2022-01-01); ; Kanokmedhakul, SomdejMetabolites of Emericella nidulans (EN) were separated by chromatographic methods from crude hexane included emericellin and sterigmatocystin, while crude ethyl acetate found demethylsterigmatocystin. These metabolites proved to be antagonistic to Magnaporthe oryzae, the causal agent of rice blast. Crude extracts and nano-particles derived from EN inhibited M. oryzae. The ethyl acetate crude extract derived inhibited M. oryzae with an effective dose (ED<inf>50</inf>) of 66 μg/mL. The nanoparticles showed better inhibition of M. oryzae than crude extracts at low concentrations. Nanoparticles, namely from crude ethyl acetate, crude methanol and crude hexane of EN were active against M. oryzae with ED<inf>50</inf> of 4.2 μg/mL, 4.5 μg/mL, 8.9 μg/mL, respectively. It detected sakuranetin (rate of flow value is 0.09) in nano-EN treated rice leaves. These nanoparticles inhibited M. oryzae and acted as a new elicitor to induce immunity. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Research investigation on microbial technology for plant disease control: a short communication(2022-01-01); Chaetomium spp. are isolated, identified and screened to control plant pathogen isolated in China. Disease interacting pathogens were found in peach diseases which were Pythium, Rhizoctonia solani (twig die back), Fusarium spp (wilt) Phomopsis, Colletotrichum dematium, Colletotrichum gleosporiodes, Phoma, Fusarium, Fusarium, Phomopsis, and Alternaria. The main primary organism caused infection to peach supposing to be Phomopsis and Fusarium destroying roots and vascular bundle, and the pathogens infected above peach tree in stem, twigs and leaves found Colletotrichum dematium, Colletotrichum gleosporiodes, and Alternaria. Bi-culture test between Chaetomium antagonistic fungus and phytopathogens was evaluated to know the control mechanism which tended to give good results. Futher testing bioproduct of Chaetomium had been also tested in tea, peach, grape and old trees with different phytopathogenic isolates and reveiced a good result to control and recovery plants from disease incidence.
