In the report, the union questions biotechnology's ability to increase crop yields and claimed that successes to date have not been the result of genetic engineering.

Responding to the report, Sharon Bomer Lauritsen, executive vice president of BIO, said: "It's absurd to deny biotechnology's contribution, among other factors, to increased crop production. Since the introduction of agricultural biotechnology in 1996, we have seen double-digit growth in corn and soybean yields."

Referencing the US Department of Agriculture's 2009 Annual Summary Crop Production Report, she noted that 80pc of the nation's corn acreage is planted with biotech varieties, and yields have increased 36pc since 1995, the last year before biotech varieties were commercially planted.

And with about 92pc of the US soybean acreage now planted with biotech varieties, yields have increased 12pc since 1995.

Acres planted to biotech crops in the US have been steadily rising each year, with 309 million acres planted in 2008.

"At a time when the US and the world are looking for science-based solutions to help meet the demands of a growing population, agricultural biotechnology is able to deliver heartier crops that yield more per acre in a more environmentally and economically sustainable way," Lauritsen said.

"The biotechnology industry is committed to providing solutions to enlist in that effort."
