Concentration of metolachlor in 2017 registered products range from 16% to 86.4%. This is referred to as the active ingredient, or a.i., of a metolachlor product.
Minnesota registration information for metolachlor and other pesticide products is available through the Kelly Registration Systems or the National Pesticide Information Retrieval System. Examples of metolachlor product labels are available through the Crop Data Management Systems (CDMS). Note that pesticide product labels change over time. The only official product label is the label attached to the container of the pesticide being used.
The MDA collects pesticide sales data to provide long-term trends in pesticide use. Sales data should not be used as an indicator of pesticide use in a given year as product bought one year may be held over and used the following year or may be returned unused to the distributor.
In 2017, over 3.5 million pounds of metolachlor’s active ingredient was sold in Minnesota (Figure 1). Fifty-nine percent of metolachlor sold in 2017 was metolachlor-only products and 41% was pre-mix combination products of metolachlor and another herbicide or herbicides.
