A nanobiosensor for the electrochemical detection of genomic DNA of P. palmivora in cacao and soil samples was developed. Through the funding of DOST-PCAARRD, the same nanobiosensor is being developed for L.theobromae. The preliminary use of the nanobiosensor to detect genomic DNA of P. palmivora in cacao and soil samples shows its potential for use in the analysis of field samples. Further optimization and field validation of the detection method is recommended for its potential to be fully realized. An ongoing project intends to perform in-house and field validation of the developed portable nanobiosensor for early detection and rapid response to manage cacao diseases. This would further increase the production of good quality cacao beans for local and international markets.
