Vegetation Management

Control Tough Brush with Invora Herbicide

The solution for controlling tough brush

Invora® herbicide is an innovative brush solution helping to restore rangeland by reducing the negative impacts of difficult to control brush species, like mesquite and huisache. Invora herbicide is labeled for privately owned non-hayed rangeland and privately owned non-hayed perennial grasslands managed as rangeland. Invora herbicide delivers an extended treatment life to manage undesirable brush, giving ranchers the opportunity to restore their rangeland.

About Invora

Invora herbicide helps restore rangeland health by reducing the negative impacts of difficult- to-control brush that compete with desirable vegetation for valuable nutrients, water, sunlight, and space. Invora combines two different active ingredients to provide better brush management and control a wide spectrum of undesirable trees, brush, and herbaceous weeds.

Trial Results:

Trial results collected four to six years after huisache applications (5 trials) and four to 10 years after honey mesquite applications (10 trials):

// By three years after treatment, huisache canopy cover was 30 percent with traditionally used treatments and only 2.5 percent in Invora herbicide treated plots

// Approximately 8.5 years after treatment, honey mesquite canopy cover was 25 percent with traditionally used treatments and only 2 percent in Invora herbicide treated plot

When considering use of Invora, these criteria must be followed:

// Do not use on hay production sites

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

// 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
