Lontrel XC provides excellent control of Canada thistle and other broadleaf weeds in close proximity to most tree species.

Why use Lontrel XC?


This Group 4 herbicide provides superior

control against tough broadleaf weeds such as Canada thistle and sow thistle by moving througout the entire plant system.

The following year after a Lontrel XC application, thistle stands are shown to be reduced by 73%.

Reliable protection

Lontrel has an all-new XC formulation for unmatched protection in even the toughest and most challenging conditions.


You choose the rate to match the size and scope of your thistle issues. Customized rates allow for complete control of target weeds while being safe for grass and other non-target vegetation.
