The U.S. Environmental Protection Agency (EPA) has authorized Section 18 emergency exemptions for the active ingredient myclobutanil to be used in Iowa for the control of soybean rust.
Use of myclobutanil – marketed under the brand names Laredo® EC and Laredo EW fungicides by Dow AgroSciences – 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 (APHIS) of the U.S. Department of Agriculture. Under this Section 18, use of this systemic triazole fungicide will be limited to a maximum of two applications.
