HARRISBURG - The Pennsylvania Department of Agriculture released a pamphlet on two new invasive weeds in Pennsylvania, Palmer amaranth and waterhemp. Both are members of the pigweed family, produce tremendous amounts of seed and are resistant to glyphosate and other herbicides.
One plant of either species produces over 100,000 seeds a season. It has come into Pennsylvania on farm equipment transported into the state from areas with the weeds. Left unchecked, they quickly take over agricultural land, making the land unusable.
