Losses in crops caused by plant pathogenic bacteria and parasitic nematode are increasing because of a decrease efficacy traditional management measures. There is an urgent need to develop nonchemical ecofriendly based control diseases. A potential approach controlling disease the use biocontrol agents their secondary metabolites (SMs). Luckily fungi especially genus Trichoderma comprise great number fungal strains that producer bioactive metabolites. In this study from ten spp. were...

Salt stress is a constraint factor in agricultural production and restricts crops yield quality. In this study, salt-tolerant strain of Trichoderma longibrachiatum HL167 was obtained from 64 isolates showing significant salt tolerance antagonistic activity to Fusarium oxysporum. T. inhibited F. oxysporum at rate 68.08% 200 mM NaCl, penetrated under eventually induced hyphae breaking, according electron microscope observations. the pot experiment, pretreatment cowpea seedlings with reduced...

Cabbage Fusarium wilt (CFW) is a devastating disease caused by the soil-borne fungus oxysporum f. sp. conglutinans (Foc). One of optimal measures for managing CFW employment tolerant/resistant cabbage varieties. However, interplay between plant genotypes and pathogen Foc in shaping rhizosphere microbial community, consequent influence these assemblages on biological resistance, remains inadequately understood.

Matricaria chamomilla flower extract was used as a biocompatible material for synthesis of zinc oxide nanoparticles (ZnONPs). The synthesized NPs were evaluated their antibacterial potential in vitro and vivo against the Gram-negative bacterium Ralstonia solanacearum, which causes devastating bacterial wilt disease tomato other crops. Synthesized ZnONPs further analyzed by UV-visible spectroscopy, Fourier transform infrared x-ray diffraction, transmission electron microscopy, scanning...

Abstract Background Ralstonia solanacearum causes bacterial wilt disease in tomato and other crops resulting huge economic losses worldwide. Several measures have been explored for the control of R. , but desired level through sustainable ecofriendly way is still awaited. Main body In this study, fungal metabolites produced by Trichoderma harzianum were investigated form crude extract management both vitro planta plants. investigation, checked their antibacterial potential at different...

The postharvest losses of litchi caused by downy blight are considerably high. We identified a natural antifungal volatile pyrone, 6-pentyl-2H-pyran-2-one (6PP), synthesized Trichoderma erinaceum LS019-2 and investigated as biocontrol for preservation. 6PP significantly inhibited the growth sporangial germination Peronophythora litchii, causal agent blight, severe cellular intracellular destructions, evidenced electron microscopic analysis. Furthermore, in treatment, fruit kept better color,...

Intrusion Detection Systems (IDS) are crucial module of cybersecurity which is designed to identify unauthorized activities in network environments. Traditional IDS, on the other hand, have a number problems, such as high rates inaccurate positives and negatives lack explainability that makes it difficult provide adequate protection. Furthermore, centralized IDS approaches issues with interpretability data protection, especially when dealing sensitive data. In order overcome these drawbacks,...

Bacillus cereus strain Bc-cm103 shows nematicidal activity and, therefore, has been used as a biological control agent to the root-knot nematode Meloidogyne incognita. However, it remains unknown whether volatile organic compounds (VOCs) produced by B. are effective in biocontrol against M. Therefore, this study, we investigated of VOCs The significantly repelled second-stage juveniles (J2s) In vitro evaluation fermentation three-compartment Petri dish revealed mortality rates incognita J2s...

Trichoderma species have received significant interest as beneficial fungi for boosting plant growth and immunity against phytopathogens. By establishing a mutualistic relationship with plants, causes series of intricate signaling events that eventually promote improve disease resistance. The mechanisms contain the indirect or direct involvement in enhancing by modulating phytohormones pathways, improving uptake accumulation nutrients, increasing soil bioavailability nutrients. They...
