PreventionPrevention of Nightflowering Catchfly is less expensive and less time-consuming than trying to control it. Make sure when you are seeding a new area you are doing so with certified weed-free seeds. If there is an infested area on your property, be sure to drive around, instead of through it. Finally, make sure to give all equipment that has been in infested fields a good clean, to make sure no seeds are transferred. Night-flowering Catchfly Control:Cultural ControlThe use of grass and forage crops, that is mowed yearly, should provide control in areas where mowing is acceptable. The infested area should be left with forage crops for at least 5 years to accomplish significant reduction of the weed seed population. Chemical ControlTrying to control older and larger plants is much more difficult and time consuming, therefore timely application is critical. Herbicides will be ineffective if applied when the plant is under stress. The herbicides will have more effect right before or right after rain due to the fact that the roots of the plants are taking in water at the time, which in turn means they will be taking in the herbicide as well. There are very few herbicides that provide adequate control over Night-flowering Catchfly. The main herbicide combination suggested is bromoxynil + MCPA.
