Pest control in turf often is a more intense affair than it is in ornamentals. After all, ornamentals allow landscape managers certain luxuries not possible with turf. For example, you can choose from a wide variety of ornamentals that have relatively few pest problems, and you can change plantings-such as color beds-from year to year to better suit conditions and avoid pest problems. Nevertheless, ignoring a pest outbreak in ornamentals usually is no more of an option than in turf. Obviously, chemical controls are just one part of an integrated pest-management program. But when you must stop an ornamental pest problem in its tracks, nothing can substitute for the right chemical.
Although most of the available landscape-pest controls are tailored to turf uses, many are available for use in ornamentals, and few ornamental-pest problems are without a chemical solution. The tables on the following pages provide you with a summary of your ornamental-pest-control options. You'll find listings for: * Insecticides. This listing shows active ingredients that have registration for insects, mites and other common landscape pests such as nematodes and snails. It includes basic product information such as form of application (such as spray, granular and trunk injection), mode of action and chemical family. The table also shows the major groups of landscape pests and whether chemicals are registered to control them. * Fungicides. The fungicide tables show similar information, including categories for the control of the major fungal and bacterial pests of ornamentals. * Herbicides. These tables show nearly all herbicides-both pre-emergents and post-emergents-with registration for use in landscape ornamentals. Due to the large number of weeds, we do not list them by species or genera. However, for post-emergents we show the groups-broadleaves, grasses or sedges-on which selective herbicides are active, or we indicate whether the the chemical is non-selective.
This "Update" does not cover registrations for greenhouse, container- or field-grown ornamentals, nor does it include products specifically intended for household, nuisance or structural pests. Although these tables group pests together for the sake of brevity, remember that you must identify the specific pest you wish to control and then ensure that the labeling of the product you wish to use lists it. In addition, although many of the products listed here also possess registration for turf, many do not. Therefore, it is not safe to assume that products you see listed here are suitable for use on turfgrass (and vice versa).
These tables are not recommendations or substitutes for label information. They are for preliminary planning only. If you would like more information about a product, you can contact the manufacturer with the information provide on page C 12. Suppliers can answer any questions you have and are happy to provide you with product information, including labels.
