Bayer announces new post-emerge herbicide MOA in early development

bayer logoBayer has announced a herbicide molecule in Phase 2 of early development that has demonstrated effective control of key resistant grasses in research trials, according to a company news release.

At the same time Bayer researchers are working to identify and develop a corresponding trait to convey herbicide tolerance to crops.

Discovery of this molecule is being complemented by a discovery-phase program to identify and develop a corresponding biotechnology trait to convey herbicide tolerance and initial approaches are under evaluation.

The announcement comes at a time when an increasing number of weed species have developed resistance to multiple modes of action, leaving growers with fewer weed control measures in their toolbox.

Phase 3 covers late development, and Phase 4 involves filing registration packages with the U.S. Environmental Protection Agency and other countries’ regulatory bodies.

Should the product come to market, it would mark the first new post-emergence mode of action for broad-acre weed control in 30 years. The last new family of herbicides were the HPPD inhibitors.

Each new herbicide takes at least 10 years and more than $250 million to bring to market.

Bayer has not yet announced a brand name for either the active ingredient or the individual products.
