Herbicide Application

In addition to annual tree trimming and right-of-way maintenance, DREMC uses selective low-volume herbicide application for controlling vegetation in the cooperative’s rights-of-way.

Herbicide application is typically scheduled from May through September (the typical growing season), to effectively manage tall-growing tree vegetation in the DREMC power line rights-of-way to improve electric reliability for our members and provide DREMC the access we need when restoring power after storm events. We have a three-year rotation schedule to cover approximately 2,000 miles of electric line annually; this is vital to controlling tree growth and maintaining service reliability.

Below is DREMC’s current herbicide mixture and application practice to help manage tree and vegetation growth near the rights-of-way:

Low Volume Foliar Mix*

Arsenal .5% + 52 ounces Method + 2 oz. Escort+ 100 gallons water

Hack & Squirt Mix*

20% Rodeo + 2% Arsenal + Blue Dye

– All branded products are to be furnished in custom blend in returnable containers where available.

– All mixes applied shall have blue dye, surfactant and drift control agent added to effectively control drift and visual marking after application.
