For the second year in a row, BASF conducted a survey of mostly Midwest row crop growers to find out their experiences during the 2013 growing season. The survey questions covered topics such as tough weeds, glyphosate resistance, current weed control strategies, whether or not they plan to change weed control strategies in 2014 and how they would do so. Results show, for example, that over 65 percent of respondents said waterhemp was the toughest weed to control last season followed by ragweed species and lambsquarters. Nearly two-thirds of growers said they’ll be changing up their weed control program by applying a preemergence herbicide before planting.
