Thirty-two isolates of Fusarium from Hawaiian Acacia koa exhibiting wilt/dieback disease symptoms were compared for their pathogenic potential on young Douglas-fir germinants in controlled laboratory tests. Only three isolates (one each of F. oxysporum, F. solani, and F. subglutinans) exhibited low virulence. All others, including isolates of F. semitectum and F. equiseti, were non-pathogenic. ...

Jasmonate (JA)-mediated defences play important roles in host responses to pathogen attack, in particular to necrotrophic fungal pathogens that kill host cells in order to extract nutrients and live off the dead plant tissue. The root-infecting fungal pathogen Fusarium oxysporum initiates a necrotrophic growth phase towards the later stages of its lifecycle and is responsible for devastating Fu...

Wilt is an important disease of tomato crop causing significant reduction in yield. In present study, the pathogenic fungus was isolated from infected plant and identified based on morphological and cultural characters as Fusarium oxysporum f.sp.lycopersici whose pathogenicity was confirmed by Koch’s postulate on tomato seedling. In vitro evaluation of extracts of 20 plant species was done by p...

lentil wilt, caused by fusarium oxysporum f. sp. lentis is one of the main limiting factors to successful lentil cultivation. effect of four antagonistic fungi, namely: piriformospora indica, sebacina vermifera, trichoderma viride and trichoderma harzianum as well as combinations among them were evaluated against fusarium wilt of lentil. in in vitro experiments, the effect of the antagonistic f...

Fusarium wilt (Fusarium oxysporum f. sp. phaseoli) is one of the most common diseases in bean (Phaseolus vulgaris) crop, and viable alternative for its control use resistant cultivars. However, number “carioca” cultivars, important commercial group Brazil, which has a good level resistance to this disease, still low. To obtain populations with higher degree resistance, seven parents different l...

The effectiveness of aqueous extract of seven locally available medicinal plants i.e. Trachyspermum ammi (seeds), Zingiber officinale (rhizome), Tinospora cordifolia (leaves), Cymbopogon citratus (leaves), Moringa oleifera (bark) were evaluated against the plant pathogenic fungus i.e. Fusarium oxysporum f. sp. lini (causing wilt in linseed). The plant extracts were screened for their antagonist...
