Meet the New Product Enhancing Bareground Results for Utility Substations

April 1, 2022
As vegetation managers work to maintain total vegetation control on utility substations, a new herbicide product is available to help practitioners conquer incompatible vegetation that threatens both utility infrastructure and worksite safety.
Vegetation managers know the importance of controlling incompatible plant species, as they threaten worksite safety and the integrity of utility infrastructure. That’s why beds of rock or stone are commonly laid throughout utility substations.

This impactful strategy is a safety measure taken to reduce hazards for on-site personnel. When weeds or other forms of incompatible vegetation develop in substation yards, they not only pinpoint weak spots in surface materials, but also pose a variety of threats to worksite safety and equipment. These hazards include, but are not limited to:

  •  Infrastructure interference
  • Risk of electrocution due to compromised insulation
  • Collection of flammable organic debris
  • Habitat development for wildlife species, including venomous snakes
  • Increased risk of equipment corrosion due to moisture and high humidity
  • Line-of-sight issues for equipment, as well as tripping and slipping hazards

Herbicide applications are most often used by vegetation managers to maintain total vegetation control (TVC) throughout utility substations. However, many targeted plants grow resistant to repetitive treatments over time. As problematic vegetation becomes less susceptible to commonly used chemistries, it’s imperative vegetation managers revisit their product options to optimize results in the field. That’s why industry professionals are encouraged to consider the benefits of a refined formulation that can enhance bareground results: Piper® EZ herbicide.


Piper® EZ herbicide is a new suspension concentrate liquid formulation that offers enhanced results and program flexibility for utility vegetation managers working to achieve TVC throughout utility substations. As a leader in vegetation management solutions, Corteva Agriscience recently reached an agreement with Valent U.S.A. LLC to become the exclusive distributor of Piper EZ within the United States. Now available through Corteva authorized distributors for the 2022 season, this new bareground solution delivers two new modes of action that can control and impede the development of problematic species that commonly invade utility substations, including select grasses and a variety of broadleaf weeds. Other product benefits include: 

  • Fully registered by the U.S. Environmental Protection Agency
  • Knocks incompatible species back and prevents emergence of germinating seedlings
  • Enhances resistance management with two active ingredients featuring differing modes of action
  • Maintains activity on EPSP synthase-resistant weeds

As a highly effective preemergence herbicide, Piper EZ also can be used in tandem with tank-mix partners, such as TerraVue® herbicide from Corteva, to provide months-long residual and postemergence activity after targeted species emerge earlier in the year.

Integrating this performance-enhancing herbicide can be the linchpin to improving the efficacy of substation management programs in 2022 and beyond. Learn more about Piper EZ and the plant species it can effectively control by visiting the complete product page online.
