Contains linuron, the active ingredient used in Linex® 4L Herbicide
Synex™ 4 L contains the active ingredient linuron, a photosystem II residual herbicide from the urea chemical family. This distinction is important because it allows Synex 4 L to be effective against weeds that are resistant to the active ingredients atrazine and metribuzin. By using Synex 4 L at a pre-emergent timing, growers can manage tough broadleaf weeds and grasses while reserving other herbicide products for potential in-season use.
