All results refer to responses from sampled producers concerning specific practices.
The producers were asked how many acres of a specific commodity they had, and what pesticide management practices they used. Pests were defined as weeds, insects, and diseases. If the respondent used a specific practice on a crop, it was assumed the practice was used on all of the acres of that crop. Rotating crops to control pests was the leading pest management practice on corn, used on 67 percent of the acres. Rotating crops to control pests was also the most widely used pest management practice on alfalfa acreage, at 48 percent.
