Effect of rhizosphere bacteria to reduce Fusarium infection in tomato plant

Abstract

Fusarium Saprophytic fungi, which are widely distributed in the soil, are recognized to formassociationswith plants and cause a variety of plant diseases, including tomato Fusarium wilt. In order to mitigatetheimpacts of Fusarium wilt, this study examined the effects of rhizosphere bacteria on tomato plant growthparameters, including shoot length, root length, and fresh and dry weight of the shoot and root. Basedonthe impact of bacterial treatments on growth metrics, infected plants treated with isolated three bacteria, particularly B1, showed the highest growth parameters. the notable improvement in growth characteristicsof tomato seedlings treated exclusively with bacteria as opposed to the control group. The diseasedtomato seedlings, on the other hand, showed the lowest growth metrics. Additionally, the applicationofisolated bacteria reduces the stress caused by fungal infection. This was demonstrated by the observationthat proline concentrations were low in plants treated with bacteria and high in plants infectedwithFusarium.
