Chemical Specification Guide: Herbicides

Updated Jun 15, 2012

Herbicides are one of the most frequently used chemical tools in turf management. As such, there are formulations to combat nearly every known species of weed – and some that kill indiscriminately. With so many options available, it is challenging to quickly find what you need to solve your weed problem. To help, Total Landscape Care has put together a guide that lists herbicides and the weeds they control.

The following charts are designed to offer you a comprehensive, quick resource to herbicides. In them, you’ll find a list of active ingredients and which weeds (grassy and broadleaf) they control. They include a description of other chemical characteristics, as well, such as whether the herbicide is a pre-emergent or post-emergent, and whether it’s liquid or granular. You’ll also find a table at the end of the charts where you can cross-reference active ingredients to find the brand name of chemical you want and a list of suppliers.

User’s manual
When you turn this page, you’ll find a two-page chart that describes every chemical (by common name of active ingredient) listed within the entire herbicide guide. These pages describe each chemical’s characteristics, and define the following:

  • Pre-emergent or post-emergent
  • Non-selective or selective
  • Labeled for ornamental use
  • Liquid or granular
  • Plant tolerances (which major turfgrass species are tolerant of the chemical)

The next two pages chart which of these chemicals (again, by active ingredient) you could use to control grassy weeds and sedges. Notice that these are divided into pre-emergence controls and post-emergence controls.

Following that is our guide to herbicides that control broadleaf weeds. This, too, is divided into pre-emergence and post-emergence herbicides. Note that active ingredients are listed alphabetically, starting with pre-emergents.

Finally, the “Sources of Herbicides” table will provide you with a list of chemical brand names and who supplies them. On the last page, you’ll find contact information for those companies.
