The potential of virgin coconut oil (VCO) as Bio-pesticides to control Ganoderma boninense (Pat.) In Vitro / Nur Ashilah Datu Dasir

The availability of fewer antifungal agents with fungicidal actions prompted this present study to investigate the potential of virgin coconut oil as bio-pesticides to control Ganoderma boninense (Pat.) in vitro. The objectives of the study were to determine the effectiveness of VCO in inhibiting G. boninense and to determine VCO effective concentration to suppress growth of G. boninense. Isolates of G. boninense were obtained and their susceptibility to virgin coconut oil and fungicide with hexaconazole as active ingredient were studied by using dual culture assay test and degradation test. Their effectiveness is determined by determination of Percentage Inhibition of Radial Growth (PIRG). It was found out that each concentration of VCO showed 0% inhibition toward G. boninense. The results of this study showed that virgin coconut oil was not able to inhibit growth of G. boninense at any concentration in vitro. Fungicide with hexaconazole as active ingredient showed increase of PIRG with increasing concentration of fungicide.
