TURFGRASS INSECT REFERENCE

Turfgrass insects are most effectively managed through a combination of sensible cultural practices and insecticide applications. This is a method commonly referred to as integrated pest management (IPM). Key IPM cultural elements include selecting turfgrass species most appropriate for a site and proper thatch management, mowing, irrigation, fertilization, and aeration. Management of these factors, along with appropriate insecticide applications, goes a long way toward preventing turfgrass damage.

Turf-damaging insects can be divided into three categories: those that feed below ground on turfgrass roots, those that feed in the thatch layer on turfgrass crowns and stems, and those that feed above ground on turfgrass blades. As with any turf or ornamental pest - weed, disease, or insect - close inspection and proper identification are important prerequisites for control and critical to proper management. (If and when you decide on an insecticide application, please read the insecticide label on the container and follow the intructions on rates and application.)

When turf-damaging insects are present in populations high enough to warrant control, it's important to select the appropriate insecticide. Some insecticides offer broad-spectrum control of many insects, while others are more limited. Likewise, it's important to apply the product to ensure adequate contact with the target pest. Most insecticides are applied on a curative basis following identification of insect populations above an allowed threshold. However, some products can be used proactively on high-risk areas or sites with a history of serious infestation. For example, there are insecticides available to prevent white grubs when applied prior to egg lay.

Whether you take a proactive or reactive approach to turf and ornamental insect control really isn't the most important issue. What is important is proper insect identification and conscientious insecticide usage. Both will go a long way toward protecting the lawn and landscape, as well as the environment.
