HARRISBURG - Be on the lookout for Palmer Amaranth! Pennsylvania's newest weed threat is resistant to glyphosate and other herbicides. And one plant produces over 100,000 seeds a season.

While it has not yet crossed into Pennsylvania, officials at the Pennsylvania Department of Agriculture believe that it’s only a matter of time before it shows up here. The aggressive weed has been found in Maryland, Delaware and Ohio.

While primarily a threat to agricultural row crops, the weed can easily become a nuisance in managed landscapes. And once you have it, it’s a devil to get rid of.
