Since herbicide-tolerant transgenic cotton varieties became widely available in 1997, the no-till cotton acreage has nearly doubled in the United States. A recent survey by the National Cotton Council indicates that no-till made up 29 percent of total cotton acres while reduced tillage made up 30 percent of all cotton acres in 2002.

Many growers looking for a new way to provide both burndown and season-long weed control will soon have a new tool available in their herbicide arsenal. That’s because a compound named Expert from Syngenta Crop Protection was recently approved by the U.S. Environmental Protection Agency for use in corn and grain sorghum.
