DAVAO CITY — Major banana growers and exporters said they oppose a plan to conduct field-testing of genetically modified (GM) bananas in Mindanao, saying this will affect the marketability of the region’s produce.

Stephen A. Antig, executive director of the Pilipino Banana Growers and Exporters Association, Inc. (PBGEA), said in an interview last week that such trials pose a danger to the country’s second-biggest agricultural export commodity as “it might send a wrong signal to the markets where we sell our bananas.”

Mr. Antig said those behind the plan to conduct the test should consult industry stakeholders.

“They must remember that any news will have a very huge impact on the industry,” he cautioned.

It was reported on a local television network in November that researchers from Australia are planning to carry out field trials for GM bananas that will address Fusarium wilt, also known as the Panama disease.
