Will Dismiss work on bittercress in my dormant northern Virginia fescue in winter temperatures of 30-40 degrees?


Dismiss Turf Herbicide has no temperature restrictions unless it’s above 90 degrees.  But the weeds would need to be actively growing in order for the proudct to be effective, and that is usually when temperatures are above 55 degrees.  For control of bittercress in your fescue lawn at lower temperatures, you can use something with an Ester formula like SpeedZone.  Keep in mind that the weeds would still need to be growing for best results.
