• Herbicide

The new standard in pricklypear control

Pricklypear, by nature, is notoriously slow to show symptoms, die and melt away. Faster symptoms with MezaVue® herbicide deliver a piece-of-mind benefit that the herbicide is working. Faster control means native grasses are able to respond sooner to get rangeland back into production. And, the more cactus you control, the more of that area you open to grazing.

MezaVue® herbicide provides faster visual activity — so you can trust it’s working. But you also get a higher level of control with quicker speed of kill to help restore grass productivity sooner.

Faster, long-term control

Pricklypear treated with MezaVue shows significant yellowing — so you know it’s dying — within three to four months. This quick activity ultimately leads to a faster death. The sooner pricklypear is out of the way, the sooner desirable forage grasses can reclaim that space and begin feeding more grazing livestock. 

More-consistent control

MezaVue doesn’t leave you wondering about your pricklypear control. First, there’s faster visual activity, so you know it’s on the job. And then you get more-consistent results, so you can trust MezaVue is going to kill more of the plants you treat. That’s especially true when treating individual plants, for which control can reach as high as 93 percent 12 months after application.

Improved oak tolerance; faster recovery

When you treat for pricklypear, your aim is a high level of control. But, depending on your individual goals, preserving oaks, forbs or other desirable plants is important, too. MezaVue supports ecosystem diversity through tolerance among many species and a quick recovery by species exhibiting signs of injury.

  • Application Method

    Ground broadcast applications: Spray volumes greater than 10 gallons per acre generally provide better coverage and better control, particularly in dense and/or tall foliage.

    Aerial broadcast applications: Use 4 gallons or more per acre total spray volume. Five gallons per acre or greater will generally provide better coverage and better control, particularly in dense and/or tall foliage.

    Individual plant treatment: Apply the spray mixture to individual plants until the pads and stems are wet, but not to the point of runoff. Results will be faster and more consistent if you spray both sides of the pricklypear pads.
