"Pigweed Emerging as Farmers’ Super Pest"

"Pigweed, with its ability to quickly adapt genetically, has developed Roundup herbicide resistance nearly as quickly as the crops altered by scientists to do so.

Researchers at Kansas State University said pigweed not only has an ability to alter genetics at a fast rate when faced with threats, but it can also cross among several varieties in this region to create new hybrids.

The persistence of pigweed, a soil sapping broad­leaf, is evident in Marion County fields of various crops even though farmers use various techniques to control it."
