Acetochlor Use in Minnesota


The United States Department of Agriculture's National Agricultural Statistics Service (NASS) and MDA's Minnesota Agricultural Statistic Service (MASS) collect pesticide use information through interviews with farmers and pesticide applicators. Approximately 100 to 400 interviews are made in the state during each survey to calculate statewide averages on corn pesticide use.

Collection of NASS data on acetochlor use in Minnesota started in 1994, the year acetochlor was introduced as a new product. Due to budget constraints or other program considerations, data for pesticide use on corn was not collected in 1995, 2000, 2004, 2006, and beyond.

Between 1996 and 2005, NASS data show the percentage of Minnesota corn areas receiving acetochlor has fluctuated between 28% and 42% (Figure 2). During the same time period, acetochlor application rates have fluctuated between 1.27 and 1.79 pounds per acre (Figure 3), and the total amount of acetochlor applied in the state has ranged between 2.9 million and 4.4 million pounds (Figure 4).

There appears to be a decrease in total pounds of acetochlor applied to Minnesota corn from 2001 to 2005. Other apparent trends in acetochlor use are not discernable from the NASS data.
