Engineered cotton uses weed-suppression chemical as nutrient

by Kay Ledbetter, Texas A&M AgriLife

A newly developed fertilizer system will provide nutrition to engineered cotton crops worldwide and a deadly dose to weeds that are increasingly herbicide resistant, according to a Texas A&M AgriLife Research study.

The new system applies phosphite to cotton crops engineered to express a certain gene — a gene that makes cotton able to process the phosphite into nutrition while the same compound suppresses weeds that are unable to use it, researchers said. Continue reading
