Integrated pest management (IPM) is not so much a collection of products as it is an approach, a program. Once considered to be innovative, it’s become standard procedure as growers across the country have adopted the common-sense course of action that includes scouting and prevention as well as application of chemical and biological controls.
In planning to incorporate IPM, growers follow general guidelines, which include setting an action threshold. This entails evaluating the possible pest threats as well as environmental conditions, and then determining the point at which control action must be taken. A few sightings – the result of careful scouting and observation – may not require intervention. But at what level of infestation does a pest become an economic threat?
Proper cultural practices should be employed in an attempt to prevent pests, but that doesn’t guarantee an infestation will never occur. Careful monitoring helps to identify threats, a critical step in any successful control program. Accurate, precise identification will help to prevent misuse of chemical applications, should an infestation imperil the plants.

If controls become necessary, the grower weighs the options available to provide the most effective method that also poses the least threat to plant and environment.
Common sense, but effective.
Whether you’re a grower, a landscape professional or a garden center retailer, you probably already practice some form of IPM. So you know how to track down, locate and identify the most common threats to your plants. (Or you rely on a local Extension agent to be your trusty detective.)
The trickier part is determining what needs to be done once an infestation is confirmed. You can do nothing and hope the situation resolves itself. You can count on mechanical means to rid your valuable plants of the threat, using such methods as sticky traps or a blast of water. But if your evaluation leads you to conclude that further intervention is required, you’ll have to choose among the myriad selections of biological and chemical controls.
To make your task just a bit easier, we’ve compiled a list of companies that offer products designed to help you battle the pests that threaten your crops and your livelihood. We need to state, however, that inclusion in the list does not imply an endorsement by American Nurseryman or Moose River Media. If you work with a product or company that’s not included here, we’d like to share that information with our readers.
