Who ever wrote this could have left out the "claim" part and just leave it as that. Between bayer/Monsanto and pioneer, they control about 70% of the market. The rest is distributed by other companies for instance ag reliant has 7% of the market share total, yet has extremely great products. What is not told in this is that we as agronomist, CCA's, and extension, are doing everything we can to inform the public, producers etc how to grow and manage these products where we limit resistance. These companies have a slug of technology coming down the pipeline. If producers, co-ops etc use good judgement there will few if any concerns about drift, resistance, etc. Good scouting. And good management will prevail as always.
