The U.S. Environmental Protection Agency (EPA) has granted a Section 18 quarantine exemption for the active ingredient myclobutanil to control soybean rust on soybeans in Minnesota and South Dakota. This is the first fungicide to receive a Section 18 exemption for this use. Myclobutanil is a systemic fungicide effective for treating a variety of plant diseases. The Dow AgroSciences formulations of myclobutanil are Laredo® EC and Laredo® EW fungicides. Dow AgroSciences is also working with other states for Section 18 exemption for Laredo for this use.
Use of myclobutanil under this quarantine exemption will not be allowed until the presence of soybean rust has been confirmed in the continental United States by the Animal and Plant Health Inspection Service of the U.S. Department of Agriculture (USDA-APHIS), and will be limited to a maximum of two applications under this Section 18.
Soybean rust can cause yield losses of 30-50%.
The Section 18 labeling for the Laredo EC and Laredo EW will be available from the Minnesota Department of Agriculture at www.mda.state.mn.us/, and Dow AgroSciences at www.dowagro.com.
