The Philippines has recently approved the sale and planting of a fourth biotech corn developed by Monsanto Company.

Merle Palacpac, chief of the Plant Quarantine Service of the Bureau of Plant Industry, Department of Agriculture, said that the fourth biotech corn, referred to as stacked-trait corn, is resistant to the Asiatic corn borer pest and is tolerant to glyphosate, a herbicide.

The latest approved corn combines the traits of two earlier approved biotech corn varieties developed by Monsanto, the Round-up Ready corn and Bt maize.
