Arsenal PowerLine Herbicide contains isopropylamine salt of imazapyr, an effective compound that targets various weeds and brush. With added Transport Technology, this active ingredient penetrates the weed more easily and circulates throughout its system. It translocates to the weed's growth region and disrupts protein synthesis, causing cell growth interference and death. It works on many annual and perennial grasses, including woody plants and some emergent aquatic weeds.

Where to Use Arsenal PowerLine

Wherever weeds grow rampant, Arsenal PowerLine kills them on target. You can use this powerful weed killer in grass pastures, range lands and noncrop sites like railroads and utility areas. It helps to keep weed infestations from causing problems on petroleum tank farms, pipelines and fence rows. Apply it on highway rights of way and nonirrigation ditches and for maintaining wildlife openings in protected areas. 

Target Weeds and Brush

Although Arsenal PowerLine works effectively on its own, you can use it with a tank mixture for even more control of annual and perennial weeds and grasses. It helps to kill annual bluegrass, fescue, foxtail and wild oats in various settings. You can also apply it to knock down barnyardgrass, crabgrass and clover. In areas where cattails thrive, Arsenal PowerLine provides an effective solution for eradicating and suppressing future growth. It also controls: 

  • Fleabane
  • Pigweed
  • Smartweed

  • Henbit
  • Wild lettuce
  • Little mallow
  • Honeysuckle
  • Poison ivy
