My answer was related to the fact that within the government's tool bag are a number of things that can be done, short of banning something outright, to manage risks. That's what was done with road salts. The government did not ban road salts; road salts save people's lives in winter.
The government developed management practices to reduce the risks, while still continuing to use them and save people's lives. That's the risk management aspect of it. That's what these beneficial management practices and their adoption are meant to do. They're encouraged to be adopted through farm stewardship programs and incentive programs. They're meant to manage the risks, not eliminate the use of the substance.
