Aspects of Integrated Pest Management

Insecticides should not be the only plan of action when trying to control insect pests. But they are also an important and valuable tool. The National Roadmap for IPM supports chemical management as an option, but a main focus is to reduce the risk of resistance that may develop when a system relies too heavily on chemical management strategies.

Active ingredients in pesticides target different aspects of an organism’s growth. So, when implementing an insecticide use plan, it is very important to try to rotate chemistries, also known as modes of action (MoA).

Familiarize yourself with pesticide ‘group numbers’, and try to make choices that AVOID repeated use of the same product or MoA group. Otherwise, you may inadvertently be contributing to insecticide resistance, which means that sprays will be less effective, wasting your time and money. Group numbers are usually shown on a product’s label.

If you want to know more about this concept, may I suggest this video and other material available from the Int’l Resistance Action Committee (IRAC-online(dot)org). Other great resources include OSU’s Integrated Plant Protection Center (IPPC) and the National Pesticide Information Center (NPIC).
