Suppression
Control of Canada thistle
For in crop control of top growth of Canada thistle, apply Lontrel 360 at the rate of 170 mL/acre. This will suppress
top growth of Canada thistle for 6 to 8 weeks. Some re-growth may occur by the end of the season but this will not
interfere with the harvesting of the crop.
For season long control of top growth of Canada thistle, apply Lontrel 360 at the rate of 227 mL/acre. This rate will
generally provide season long control of Canada thistle. Not all rhizomes will be killed and some re-growth may
occur by the end of the growing season.
For season long control of top growth, with a reduction of Canada thistle population in the following year, apply
Lontrel 360 at the rate of 336 mL/acre. This rate will provide season long control of Canada thistle and suppression
into the following season, resulting in a reduction of the total number of Canada thistle shoots in the treated area.
