(Fort Collins, Colorado-AP) -- A herbicide spray that comes from a weed and is kinder to the environment could be available to consumers within the next year or two.
The chemical is called catechin and it's found naturally in knapweed.
A scientist from Colorado State University recently identified and isolated it for the first time.
Jorge Vivanco says catechin is the reason why knapweed can spread across such a large area so quickly. The chemical kills all the plants around it.
Grasses and grassy-like plants such as wheat show some resistance to catechin.
That might mean it could be used on lawns to kill weeds or in wheat fields without damaging the crop.
