2015 | Total Landscape Care | Chemical Guide 17 HERBICIDES Turfgrass Herbicides W hen it comes to controlling weeds in turf, you've got options. Lots of them. There are active ingredients and formulations to combat nearly every known species of weed. Some seek out weeds and kill them selectively while others kill indiscriminately. With so many options available, it is challenging to quickly find what you need to solve weed problems, but the following charts are designed to offer you a comprehensive, quick resource to herbicides. Our charts are in table format because this is the most practical way to take you from the problem (the pest you're trying to control) to the solution (the chemical that will control the pest). This format also allows us to provide other useful information. 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 formulation is liquid or granular, selective or not, and whether the product is also labeled for ornamental use. Note that the purpose of this chart is to list chemicals registered for use on turfgrass. Some of these are also labeled for ornamentals. However, we'll profile products designed strictly for ornamentals in a chart of their own. 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: s 0REEMERGENT OR POSTEMERGENT s .ONSELECTIVE OR SELECTIVE s ,ABELED FOR ORNAMENTAL USE s ,IQUID OR GRANULAR s 0LANT TOLERANCES WHICH MAJOR TURFGRASS species are tolerant of the chemical) The two pages after that table list which of these chemicals (again, by ac- tive ingredient) you could use to control grassy weeds and sedges. Notice 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 informa- tion for those companies. As always, use these tables for prelimi- nary planning only. Always read and follow label instructions for each chemical you use. The Chemical Guide is not a substitute for label information.
