A report from a working group of Danish scientists on the co-existence of genetically modified crops with conventional and organic crops concludes that for maize, beets, potatoes, barley, wheat, oats, triticale, rye, lupine, broad beans and peas coexistence seems feasible, if an extensive list of farming measures was taken. However for "oilseed rape, grass seed, clover seed, and vegetable seed, the problem is so extensive, that further evaluation is required" the scientists write. Additional costs for farmers will vary considerably the group estimates.</p><p><a href="http://www.zs-l.de/gmo/downloads/dk_coexistence_sum.pdf">Summary of the working group report</a></p><p><a href="http://www.fvm.dk/high_final.asp?page_id=455 ">More information, some in English, available here</a>
