Genetically engineered crop plants have been developed to allow for better control of weeds using herbicides, but excess use has raised concerns about the impact on human health and some weeds have developed resistance to common herbicides.
Purdue - University - Researchers - Compound - Weeds
Now, Purdue University researchers have developed a compound effective for controlling weeds that is also safe for people and the environment. They also developed a simple system for farmers to create plants resistant to this new herbicide.
"Herbicide use is essential for modern agricultural production worldwide," said Chunhua Zhang, an assistant professor of botany and plant pathology in Purdue University's College of Agriculture. "The herbicide we...
