Ornamental pest controls

The appearance of turf may seem to get all the attention, but landscape ornamentals can be just as critical. Just wait until a tree dies, or gets covered with tent caterpillars. Or the annuals you were banking on for a big splash of color become infested with mites or some disease that ruins the bloom. Such problems bring home the importance of healthy, pest-free ornamentals, and how ornamental pest problems can ruin a landscape's appearance.

Integrated pest management in ornamentals depends heavily on choosing plants that tolerate prevalent pests, as well as maintaining plants in a healthy, vigorous condition. If you address these two issues, you will reduce or eliminate many pest problems. Still, it's inevitable that some outbreaks will occur, and when they do, you need a way to control them.

Fortunately, pest control choices for ornamentals are numerous. The tables on the following pages provide you with a summary of pest-control options for ornamentals. You'll find listings for:

* Insecticides. This table shows you active ingredients that have registration for insects, mites and other categories of landscape pests. It includes basic product characteristics such as form of application (spray, granular, trunk injection, etc.), mode of action, chemical family and systemic properties. The table also shows the chemicals that are registered to control the listed pests.

* Fungicides. The fungicide table shows similar information, including categories for the major fungal pests of ornamentals.

* Herbicides. This table lists herbicides-both pre-emergents and post-emergents-with registration for use in landscape ornamentals.

Each table also lists available brands and suppliers for each active ingredient. On page Contractor 8, you'll find ways to pursue additional product information directly from the suppliers.

This Update cover only pests of landscape ornamentals. Structural, nuisance and household pests are omitted, as are pests of greenhouses and container- and field-grown ornamentals. Pests controlled are grouped together due to space limitations. However, you must identify the specific pest you wish to control and then ensure that the labeling of the product you wish to use allows that use.

These tables are not recommendations or substitutes for label information. They are for preliminary planning only.

Although many of the products listed here possess registration for turf in addition to ornamentals, many do not. Therefore, do not assume that products you see listed here are suitable for use on turfgrass.
