Crude (1 µg.mL-1 ) obtained from PDB medium showed 2.50 ± 0.64 mm and 1.97 ± 0.21 mm inhibition zone against X. campestris and C. michiganensis respectively compared to positive reference (streptomycin) and negative refrence (EtOAc) using disc diffusion method. However, the same concentration of crude (1 µg.mL-1) showed 62.20 ± 2.51% ...

...otiorum is a serious phytopathogen resulting in significant loss of crop yield. Trichderma hamatum has the capacity to inhibit S. sclerotiorum growth by production of toxic metabolites and mycoparasitism. In vitro bioassays were used to evaluate the efficacy of T. hamatum and difenoconazole alone or its combinations against S. sclerotiorum. The results showed that T. hamatum could infect and destroy the mycelia and...

...ial activity against two phytopathogenic bacterial species (Clavibacter sp. and Xanthomonas sp.) and a human pathogenic bacterium (Escherichia coli) in 2016. Experiment was carried out by using complete randomized design with three replications in vitro. Phytochemical analysis reveals that the methanolic fraction of oil possesses metabolites like carbohydrates, amino acids, alkaloids, flavonoids and glycosides. To test the antibacterial activity of the extract...

Sonchus asper was assessed for its antifungal activity against R. solani. The methanolic
extract was prepared by soaking dried root biomass in methanol and analyzed by GC-MS.
Antifungal potential of the extract was detected in test tubes filled with malt extract broth.
The results revealed fungal biomass was significantly re...

On the other hand, Ganoderma boninense has been identified as the phytopathogen causing basal stem rot (BSR), a devastating disease in oil palm crop (Elaeis guineensis). In this study, the in vitro and in planta inhibition of G. boninense using Trichoderma isolates were evaluated. A total of 20 Trichoderma isolates were collected. Among...

Bacillus amyloliquefaciens IIHR BA2 (Indian Institute of Horticultural Research, Bacillus amyloliquefaciens 2) is one such potential bacterial bioagent that demonstrated effective nematicidal activity against root knot nematode, Meloidogyne incognita, a major biotic constraint in successful crop production. This study aims to decipher the mechanism of action of B. amyloliquefaciens IIHR BA2 again...

Recently, the application of phylogenetics to plant pathology greatly promotes the discovery of larvaceous fungi. For example, novel genera in Cryphonectriaceae were described as phytopathogens continuously in the past two decades. Cryphonect...

Extracts of the decomposed garlic and olive wastes gave inhibition percentages ranging from 25-100 %, against the tested fungal pathogens. Transmission electron microscopy (TEM) showed cyto-morphological alterations and empty cavities in hyphae of the treated R. solani. Moreover, qualitative and quantitative analyses of the phenolic compoun...

The major aim of this study was to isolate indigenous Trichoderma that can be used as a potential biocontrol agent (BCA). Currently, we isolated 14 native fungal isolates from vermicompost, agricultural soils and infected substrates, and identified them as Trichoderma spp. based on their morphological characteristics. Isolates d...
