A surge in traditional (non-glyphosate-resistant) soybean varieties “could signal a sea change in the seed industry,” reports University of Missouri Plant Sciences Research Associate Howard Mason.

The University of Missouri Variety Testing program saw a significant increase in non-glyphosate-resistant varieties in 2009, amounting to almost 15% of total varieties, “the biggest jump we've seen,”Mason says.

The number of non-glyphosate varieties dropped most of the past decade, falling to a low of 1% in 2006, he reports.
