New genetic vulnerability to herbicide found in nearly 50 sweet and field corn lines
URBANA, Ill. — When a sweet corn breeder reached out in 2021 to report severe injury from the herbicide tolpyralate, Marty Williams hoped it was a fluke isolated to a single inbred line. But two years later, after methodical field, greenhouse, and genetic testing, his new Pest Management Science study not only confirms sensitivity to tolpyralate in 49 sweet corn and field corn lines, but also reveals a new genetic vulnerability that may affect corn more generally.
Tolpyralate is a relatively new ...
