Two groups issued contrasting reports on Thursday on the state of biotech crops, with one touting acreage growth while the other cited continued resistance by governments and consumers. The biotech industry-supported Acquisition of Agri-Biotech Applications (ISAAA) said that with U.S. farmers leading the way, the global area planted with genetically modified crops grew 13 percent to 252 million acres in 2006. The number of farmers planting biotech crops grew 2 percent to 10.3 million, because of substantial economic, social, environmental, and agronomic benefits, ISAAA said.
