92 Minor Use Registrations

—Ken Sapsford.

“If you have an issue, the system works very well.”

If you have specific weed or insect problems in crops that aren’t covered by herbicide or insecticide registration, you should bring the issue forward to your provincial commodity group, says Ken Sapsford, a weed specialist from the University Saskatchewan (U of S). The commodity group can then use the minor use program to work toward an important registration that a chemical company on its own could not justify, financially.

The program, co-ordinated by Agriculture Canada, was introduced in 1998. “Since the program was started we have looked at 50 different crops with 67 different pesticides. We now have 92 different minor use registrations available to Western Canadian farmers,” Sapsford says.

Decisions aren’t made overnight, but requests are reviewed in a timely manner, he says.

Here’s a quick overview of the process: Farmers make a request to the relevant commodity group, the commodity group then makes a request to the provincial minor use co-ordinator, and from there it is referred to the Agriculture Minor Use Centre for consideration. The centre selects 33 priority projects each year.

“If you have an issue, the system works very well,” says Sapsford.

For more information on the Minor Use Centre or for a complete list of all registrations in Canada, visit the centre’s website. It is a long website, so the simplest approach is to Google “Agriculture Canada Minor Use Registrations.” The webpage should be the first result that comes up.
