Turfgrass insecticides

This is the second in our series of Chemical Updates, covering turfgrass insecticides. Each year we revise the Updates to provide you with the most up-to-date and complete lising of its kind. Here you'll find the information you need to review your control options for virtually every significant turfgrass pest.

Using the Updates This Update covers insecticides registered for use on turfgrass. The information is broken out into several sections providing important information for your pest-control planning.

* Chemical name. You may know a chemical by its brand name. However, the same active ingredient may be present in numerous brands. Therefore, we list chemicals by the trade or common name of the active ingredient(s). This eliminates redundancy and reduces confusion with brand names.

* Chemical class. Chemical rotation is an important aspect of integrated pest management, helping to slow the development of resistance in pests that require repetitive treatments. Effective rotation means not just switching chemicals but also using chemicals from different classes. This section gives you the information you need to do this.

* Mode of action. The section tells you whether a chemical works through direct contact or via ingestion (or both).

* Application form. This is a key aspect of product selection. Many applicators specialize in one form of application (such as liquid or granular), so it's important to know whether a chemical will suit your operation.

* Insects controlled. This section comprises the heart of the Insecticide Update. After all, you use insecticides for a specific reason-to control insects. You need to know the products that are labeled for the specific pests for which you need to treat.

* Brands and suppliers. On page 40, you'll find a table that lists suppliers and their brands for each active ingredient. The following page provides you with contacts if you need more information about products that interest you.

Rely on labels Remember that product labels are the ultimate source of information for pesticides. They give you important details about using the product, maximizing its effectiveness and minimizing risk. Use these tables for preliminary planning only, and always read and follow label instructions each time you use a pesticide. The Updates are not a substitute for label information. When a label leaves you in doubt about how to use a chemical, contact the manufacturer directly. Cooperative Extension agents also are reliable sources of information.

Pest control information on the web Many turf and ornamental professionals now rely on the Internet as a tool for their businesses. This applies to pesticides in significant ways. Most chemical manufacturers maintain websites (which we list on page 41) and, in many cases, you can download chemical labels. This is a tremendous resource for applicators seeking detailed information about a product.

Grounds Maintenance now offers the Chemical Updates in searchable form through our website-www.grounds-mag.com. This on-line supplement to the tables you see here is an easy way to view your pest-control options. You can choose an insect pest and find which chemicals are labeled for it or, conversely, choose a chemical and then view a list of pests it controls.

Be sure to look for the other Updates as they appear throughout the year. In the following months you'll find tables that cover turf fungicides, pesticides for use on ornamentals, fertilizer/pesticide combination products, non-selective herbicides, plant growth regulators and vertebrate pest controls.
