Evaluation of fungicides and biopesticides for the control of Fusarium wiltof tomato

Fusarium wilt is highly destructive soil borne pathogen in tomato. current study was carried out to evaluate commercially available fungicides and bio-fungicides in-vitro and in-vivo,for their efficacy against fusarium oxysporum f.sp. lycopersici. firstly four fungicides were evaluated under laboratory conditions. three promising fungicides,two biopesticides and trichoderma harzianum were further applied both in greenhouse and field experiments. during in-vitro studies pda amended with fungicides with different treatments @ 1% almost completely inhibited the growth of fol with varying degree of success whereas nativo being the most effective treatment with 98% reduction in growth as compared to control. nativo significantly reduced the disease incidence (32.75 %) at concentration of 1%. while poly-beta-hydroxyl-butyric-acid effectively promoted the tomato growth. maximum reduction in disease (30.14 %) was expressed by nativo followed by teagro (25.06 %) under field conditions. nativo was found to be the most effective fungicide for management of fol both in vitro and in vivo.further field evaluations of the fungicides are required. © 2017,pakistan botanical society. all rights reserved.
