Aqueous leaf extract of four different species of Datura viz. D.stramonium L., D. innoxia Mill.Gard, D. metal L. and D. ferox L. Amoen were tested for their antifungal activity against phytopathogenic molds in terms of mycelial growth of Alternaria solani and Fusarium oxysporum f.sp. udum causing early blight of tomato and wilt of pigeonpea respectively. The extract of Datura sp. at 5, 10, 15 a...

ABSTRACT Fusarium species can cause severe root disease and damping-off in conifer nurseries. Fusarium inoculum is commonly found in most container and bareroot nurseries on healthy and diseased seedlings, in nursery soils, and on conifer seeds. Isolates of Fusarium spp. can differ in virulence; however, virulence and colony morphology are not correlated. Forty-one isolates of Fusarium spp., mo...

Essential oils from four plants, i.e. geranium, rosa, lemon and mint were tested for their activity in vitro and in vivo against Rhizoctonia solani and Fusarium oxysporum f. sp. phaseoli, the cause of root rot and wilt of beans. In vitro, they were found to have an inhibitory effect against the mycelial growth of R. solani and F. oxysporum f. sp. phaseoli. Complete inhibition in fungal growth w...

Forty-three Fusarium oxysporum strains and one Fusarium solani strain were analyzed for genetic diversity. These strains represent a wide range of geographic locations and were collected primarily from tomato (Lycopersicon esculentum) roots. Among all 43 F. oxysporum strains, 21 were not pathogenic to tomato, 20 were pathogenic, including 13 strains of Fusarium oxysporum lycopersici and seven s...

fusarium oxysporum f. sp. albedinis (foa) is a soil borne fungus causing the most serious disease of date palm (phoenix dactylifera l.) called “bayoud”. in the present study, five medicinal plants from the algerian sahara (southwest of algeria): limoniastrum feei (aerial part, roots), launeae arborescens (batt.) murb. (aerial part, roots), fredolia aretioides moq. et coss. (aerial part, roots),...

BACKGROUND Biotrophic interaction between host and pathogen induces generation of reactive oxygen species that leads to programmed cell death of the host tissue specifically encompassing the site of infection conferring resistance to the host. However, in the present study, biotrophic relationship between Fusarium oxysporum and chickpea provided some novel insights into the classical concepts o...

Crown disease (CD) is infecting oil palm in the early stages of the crop development. Previous studies showed that Fusarium species were commonly associated with CD. However, the identity of the species has not been resolved. This study was carried out to identify and characterize through morphological approaches and to determine the genetic diversity of the Fusarium species. 51 isolates (39%) ...

during 2003-2004, a number of rhizospheric soil samples were collected of either healthy or symptomatic field grown melon plants infected with fusarium oxysporum f. sp. melonis race1/2 (fom). twenty one bacterial strains capable of inhibiting fom including burkholderia sp., bacillus sp., streptomyces sp. and pseudomonas fluorescens were isolated. the strains colonized roots of “long melon” cult...

fusarium wilt of chickpea, caused by fusarium oxysporum f. sp. ciceris, is one of the most important diseases of this plant in iran. in order to control this disease biologically, fluorescent pseudomonas were isolated from the rhizosphere of chickpea plants and enumerated using king’s medium b (kb). antifungal activity of 80 bacterial isolates against fusarium oxysporum f. sp. ciceris was evalu...
