Abstract
Evaluation of tea tree oil (TTO) was conducted to determine its efficacy on the enzymatic activity in Cavendish banana when challenged by FocTR4. At screenhouse, there was a significant increased accumulation of pathogenesis-related proteins in plants with sustained application of TTO at 6ml/L. This resulted to induction of resistance manifested by the lowest degree of rhizome discoloration, pseudostem splitting and stunting at 10 weeks after TR4 inoculation. Similar observations were noted in the field wherein there was an increase of enzymatic activity in TTO-treated plants compared to untreated samples. This increase was demonstrated by a significant lower incidence of the disease both in GN and FW-tolerant selection.
