How Roundup Custom Aquatic and Terrestrial Herbicide Works

Roundup Custom Aquatic and Terrestrial Herbicide contains glyphosate, a chemical ingredient that kills weeds without harming crops. It inhibits the weed's enzymes that are involved in the synthesis of tyrosine, tryptophan and phenylalanine, three important aromatic amino acids. The glyphosate penetrates the foliage of actively growing plants and only works as a postemergent herbicide. You should use Roundup Custom with a nonionic surfactant to improve coverage and control.


Where to Use Roundup Custom Aquatic and Terrestrial 

Use Roundup Custom Aquatic and Terrestrial Herbicide in crop and noncrop areas such as agricultural farms and ornamental turf. It's helpful in preventing invasive weed growth near aquatic areas; however, you should never apply this herbicide directly to the water. Otherwise, it could kill fish and other aquatic invertebrates. Apply Roundup Custom on industrial and commercial sites to keep landscapes free of weeds. You can also use it to prevent woody brush from growing in reforestation sites or along roadsides.


Roundup Custom Target Weeds

Roundup Custom Aquatic and Terrestrial Herbicide targets numerous weeds that prevent turfgrass and plants from receiving vital soil nutrients and sunlight. Apply this herbicide as a handheld injection to control hemlock, knotweed and Canadian thistle. It also targets other species such as:

  • Barnyardgrass
  • Bluegrass
  • Chickweed
  • Crabgrass
  • Fleabane
  • Foxtail
  • Nightshade (black)
  • Ragweed
  • Smartweed
  • Velvetleaf

Application Tips

Enjoy a Weed-Free Lawn and Field With Roundup Custom Herbicide

Roundup Custom Herbicide is a useful herbicide and kills up to 200 different weed species. It targets both annual and perennial weeds, offering broad-spectrum control throughout each season. Because this herbicide only works on actively growing plants, you'll need to use a pre-emergent product for weed prevention. However, Roundup Custom is more than enough to combat post-emergent weeds in many settings. If weeds threaten your lawn or crops, round them up with Roundup Custom herbicide.


It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Do not apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application.
