Abstract:

Cucumber vascular wilt pathogen, Fusarium oxysporum f. sp. cucumerinum is one of the most destructive organisms that hampers the cucumber production under protected cultivation and results in huge economic loss to farmers. Trichoderma spp., a potent biocontrol agent screened against F. oxysporum f. sp. cucumerinum in vitro resulted that T. virens TRI 37 effectively inhibited the mycelial growth of pathogen to about 68.0% compared to other isolates. An oil based formulation of effective Trichoderma spp. was developed with initial conidial concentration of 1 1010. The formulation remained stable for more than 180 days with conidial concentration of 1 108. Efficacy of oil based formulation on growth parameters of cucumber seedlings in protray experiments revealed that oil based formulation of T. virens TRI 37 effectively increased the shoot length (28.74 cm, 14.54 cm), root length (14.64 cm, 19.14) and stem girth (1.76 cm, 1.72cm) in comparison to other isolates in vermicompost: sand: soil (1:1:1) and coir pith medium respectively.
