The Effects of Biopesticide and Fusarium oxysporum f.sp. vanillae on the Nutrient Content of Binucleate Rhizoctonia-Induced Vanilla Plant

Binucleate Rhizoctonia (BNR) fungi are essential for the germination of vanilla seeds. Chemical control of the soil-borne pathogen
might adversely a2ect BNR. )e purpose of this study is to determine the e2ect of Nicotiana tabacum extract biopesticides and
Fusarium oxysporum f.sp. vanillae (Fusarium) on vanilla plant nutrient content induced by BNR. Materials and Methods. )e
research design was completely randomized design with two factors and three replications. )e 5rst factor was biopesticide
(dosage of 0, 10, 20, and 30 ml/seedling), and the second factor was the application of Fusarium. Results. )e increase in the
nitrogen, phosphorus, and potassium content of vanilla was a2ected by biopesticides and Fusarium inoculation. Fusarium
inoculation has no signi5cant e2ect on nitrogen and phosphorus levels but signi5cantly a2ects potassium levels. )e biopesticide
dosage is signi5cant for nitrogen, phosphorus, and potassium. )e interaction of biopesticides with Fusarium inoculation did not
signi5cantly a2ect the parameters of nitrogen and phosphorus content, but signi5cantly a2ected potassium content. Conclusion.
)e application of biopesticides and Fusarium inoculation after induction of BNR can increase nitrogen, phosphorus, and
potassium content of vanilla plants.
