Growers are concerned about common lambsquarter, marestail, ragweed and waterhemp—and the associated herbicide resistance, according to a survey of more than 800 growers, retailers, distributors and university experts.

The survey, commissioned by BASF Corp. of Research Triangle Park, N.C., found that lambsquarter and marestail were the top weed theats for 45 percent of respondents.

In addition, 43 percent said common or giant ragweed was a concern, and 41 percent said waterhemp was a problem.

Of those surveyed, 52 percent said glyphosate resistance was a major concern.
