There’s a lot of information about Invora® herbicide that could be useful to you. For example, it has the highest rating in the ERM-1466 Chemical Weed and Brush Control Reference Guide for Rangeland, and it reduces canopy cover better than any other herbicide to restore rangeland like nothing else.
Invora herbicide has a “very high” rating for mesquite and huisache in the ERM-1466 Chemical Weed and Brush Control Reference Guide for Rangeland. According to the guide’s definitions, this means that Invora herbicide kills 76%-100% of target plants. Products with a “high” rating kill 56%-75%.
Brush/woody plants: Catclaw acacia, coyotillo, huisache, honey mesquite, western honey mesquite, catclaw mimosa, Texas mountain laurel, common persimmon, Texas persimmon, flameleaf sumac, yucca.
Broadleaf weeds: Common broomweed, musk thistle, wild carrot, dogfennel, bitter sneezeweed, cocklebur, wooly croton, dandelion, bull thistle, horsenettle, kochia, prickly lettuce, marestail, western ragweed, tall ironweed, velvetleaf.
Ten years after treatment, huisache canopy cover was 8.33% in Invora herbicide-treated plots versus 100% with traditionally used chemical treatments; mesquite canopy cover was 2.0% in Invora herbicide-treated plots versus 30% with traditionally used chemical treatments.
Invora herbicide is a patent protected group 4 herbicide consisting of a combination of aminocyclopyrachlor and triclopyr in an amine liquid formulation. It is labeled for use in Arizona, New Mexico, Oklahoma and Texas.
The active ingredients are absorbed through the leaves and the root system via both the xylem and phloem and transported to the crown and bud zone to stop new growth before it starts. It also offers PRE- and POST-control of many broadleaf weeds through both root and foliage uptake.

“When Invora herbicide came along, we started seeing pretty high consistent effects, on huisache in particular. And so, we’re monitoring this over a seven-year period. And the results to me are very startling because there’s been very little reinfestation.” - Dr. C. Wayne Hanselka // Texas A&M Extension professor emeritus and Invora herbicide trial supervisor |
Other key factors such as grazing management and environmental conditions can impact treatment longevity, resulting brush cover, treatment life, forage production and more.
