A federal US court overturned government approval of a variety of sugar beet, saying federal regulators wrongly approved the commercialization of the genetically engineered sugar beet two years ago.

The agriculture giant, Monsanto, developed the concerned sugar beets that pose resistance to Monsanto's glyphosate herbicide roundup and promoted the sugar beets as "Roundup ready."

Judge Jeffrey White said that Agriculture Department did not reflected on the issue weather "Roundup Ready" sugar beets would finally share their genes with other crops.

Critics' main concern is that the herbicide-tolerant plant could spread to conventional sugar beet plants via cross pollination and will pose danger to the entire environment.

Judge Jeffrey White said, "The potential elimination of farmers' choice to grow nongenetically engineered crops or consumers' choice to eat nongenetically engineered food ... has a significant effect on the human environment."

In response to the court ruling, Louis-based Monsanto defended it product and said the ruling was based on procedure.
