Bayer’s Invora Herbicide Receives EPA Federal Approval


The Vegetation Management business within Bayer CropScience LP, announces the label for its latest product. InvoraTM Herbicide has received federal approval from the U.S. Environmental Protection Agency (EPA). The herbicide is federally registered for use on privately-owned, non- hayed rangeland and non-hayed perennial grasslands managed as rangeland in the states of Arizona, New Mexico, Oklahoma and Texas.

Invora herbicide provides the following key benefits:
• New active ingredient for managing undesirable woody brush and weeds on rangeland
• Effective long-term control of honey mesquite and huisache, two of the most problematic and wide-spread
invasive brush species in the four-state region
• A tool for use in rangeland restoration efforts
• Proven extended treatment life, resulting in favorable economics compared to past standards
• PRE and POST control of many broadleaf weeds through both root and shoot uptake
• Bayer’s next generation stewardship strategy to avoid impacting the compost industry or neighbors

“We are so pleased to see Invora herbicide receive federal approval from the EPA,” said Bayer Head of Vegetation Management Marketing, North America, Tiffany Fremder. “It is truly exciting to provide ranchers with an innovative brush solution for their rangeland restoration needs by reducing the negative impacts of difficult-to- control brush, such as mesquite and huisache. The power to reclaim the land is now in their hands.”

When considering the use of Invora herbicide, the following criteria must be followed:
• Do not use on hay production sites

• Do not harvest, compost or move any treated vegetation from the treatment site for a period of two years
following treatment

• Treated brush must degrade on the treatment site and cannot be removed

• Manure resulting from animals grazing on treated vegetation within two years of application must remain
on the treatment site

• Livestock that graze the treatment site within two years following application must be fed for three days forage not previously treated with this herbicide before transport off the property or to sites other than privately-owned non-hayed rangeland or privately-owned non-hayed perennial grasslands managed as rangelands. See label for suggestions to accomplish this requirement.

• Invora herbicide is a restricted use product. Prior to spraying, all applicators must complete picolinic acid herbicide training.

• Always read and follow label use directions, restrictions, and application and stewardship requirements. Pesticide labels provide critical information on how to safely and legally handle and use pesticide products. It is the responsibility of the landowner and/or applicator to read and follow label directions.

First sales of Invora herbicide are anticipated in April 2020 following state registrations.
