New Herbicide Targets Broadleafs

 

The flowers are attractive, but wild violets are a nuisance in southeastern lawns.

Wild violets can take over lawns in the humid southeastern portion of the country. According to Greg Constantino, Richmond, Va. branch manager for IKEX Inc., (a distributor of horticultural products), a relatively new herbicide can be used on turf to control wild violets and many other hard-to-control broadleaf weeds. It’s called carfentrazone. This material is rain-fast in three hours, and you can reseed the treated area two weeks after application. For violet control, it needs to be used in early to mid-April, when the violets are just starting to grow.
