Invora
Product Overview
The power to reclaim the land is in your hands.
Transform invasive brush into productive forage with Invora® Herbicide. Invora restores your land with innovative chemistry that redefines brush control by killing brush like mesquite and huisache with a single application.
Key Benefits
- New active ingredient for managing rangeland
- Effective long-term control of honey mesquite and huisache, two of the most problematic and wide-spread invasive brush species
- Long-term control assists landowners in land restoration efforts through brush canopy reduction, revegetation of desirable herbaceous species (when present), and improved moisture, nutrient, space and sunlight utilization.
- Proven extended treatment life, resulting in favorable economics compared to past standards
- Control of young, actively germinating weeds through both root and shoot uptake
- Targeted towards grazing lands use only, to avoid compost contamination from off-site transport of vegetation and manure.
Use & Control
- Invora herbicide is a patent protected, combination of aminocyclopyrachlor and triclopyr in an easy-to-use amine liquid formulation
- This product is labeled for use in Arizona, New Mexico, Oklahoma and Texas
- Rate range for broadcast sprays is 12-48 fl oz./A; see label for rates on specific species
- Broadcast applications targeting brush must include MSO-OS adjuvant, unless otherwise stated on the label
- Warm, moist conditions following treatment promote the activity of Invora herbicide
- Rain-fast at 1 hour after application
When considering the use of Invora herbicide, these criteria must be followed:
- Do not use on hay production sites
- Do not harvest, compost or move any treated vegetation from the site for a period of 2 years following treatment
- Treated brush must degrade on the treatment site and cannot be removed
- Manure resulting from animals grazing on treated vegetation within 2 years of application must remain on the treatment site
- Livestock that graze on the treatment site within 2 years following application must be fed for 3 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 recommendations to accomplish this requirement.
- Invora herbicide is a Restricted Use Product. Prior to spraying, all applicators must complete picolinic acid herbicide training.
