<o:p></o:p></span></h1>
<p class="m5697311525403449024govdheader" style="mso-margin-top-alt:6.0pt;margin-right:0in;margin-bottom:11.25pt;margin-left:0in">
<strong><span style="font-size:10.5pt;font-family:"Helvetica",sans-serif;color:black">WASHINGTON
</span></strong><span style="font-size:10.5pt;font-family:"Helvetica",sans-serif;color:black">– Today, the U.S. Environmental Protection Agency (EPA) is releasing for public comment its proposed registration for three end-use dicamba products for broadleaf
weed control in dicamba-tolerant cotton and dicamba-tolerant soybean. EPA has conducted a robust human health risk assessment for these proposed products and has not identified any human health or dietary risks of concern. Additionally, the agency is proposing
to put several measures in place to protect against the ecological risks found in EPA’s assessment. These new products would give farmers an additional tool to help manage crops and increase yields in order to provide a healthy and affordable food supply for
our country. <o:p></o:p></span></p>
<p class="m5697311525403449024govdheader" style="mso-margin-top-alt:6.0pt;margin-right:0in;margin-bottom:11.25pt;margin-left:0in">
<span style="font-size:10.5pt;font-family:"Helvetica",sans-serif;color:black">Dicamba is an herbicide that has historically been used for control of emerged broadleaf weeds in a variety of food and feed crops and in non-agricultural settings. These proposed
dicamba products would allow postemergence applications to dicamba-tolerant cotton and soybean, commonly referred to as "over-the-top" (OTT) use. OTT dicamba applications aim to remove emerged broadleaf weed species, particularly those resistant to other herbicides
that compete with cotton and soybean plants and potentially reduce crop yield. OTT dicamba products have high benefits in both cotton and soybean for controlling these herbicide-resistant weeds and managing resistance to herbicides in the future. <o:p></o:p></span></p>

<span style="font-size:10.5pt;font-family:"Helvetica",sans-serif;color:black">In addition to its proposed registration decision, EPA has also released its human health risk assessment, benefits and impacts assessment, ecological risk assessment and draft biological
evaluation. EPA has not identified any dietary, aggregate, non-occupational or occupational risks of concern for potential human health exposure from the proposed uses of dicamba on dicamba-tolerant cotton and dicamba-tolerant soybean. Additionally, EPA has
not identified any risks of concern for aquatic invertebrates, fish or aquatic plants. EPA concluded low risk for honeybees and other non-listed bees from the proposed uses of dicamba. <o:p></o:p></span></p>

<span style="font-size:10.5pt;font-family:"Helvetica",sans-serif;color:black">As expected of an herbicide, dicamba does pose risk to certain plants. In response to those findings, EPA has developed new, additional proposed mitigations to minimize impact to
certain species. With these proposed mitigation measures in place, EPA’s draft biological evaluation predicts that the use of dicamba will not result in a likelihood of future jeopardy for the survival of any listed species, or a likelihood of adverse modification
for any designated critical habitat. The proposed registrations also would not pose an unreasonable risk to human health or the environment with these mitigations. <o:p></o:p></span></p>
