The initial study was published in 2021 with an article titled "Local adaptation to continuous mowing makes the noxious weed Solanum elaeagnifolium a superweed candidate by improving fitness and defense traits."

A study published in Nature's Scientific Reports has found that frequent mowing of Solanum elaeagnifolium may help create a "superweed."

“I hate to use the ‘superweed’ term, but you know, these are more superweeds than the Roundup-resistant weeds when they were called superweeds,” says Pat Tranel, a crop scientist at the University of Illinois.

“I thought they were kind of pretty. I didn’t know about the whole superweed thing.”

Palmer amaranth has taken root as a herbicide-resistant ‘superweed’ in many US cotton fields.
