less risky pest controls are chosen first, including highly targeted chemicals, such as pheromones to disrupt pest mating, or mechanical control, such as trapping or weeding. If further monitoring, identifications and action thresholds indicate that less risky controls are not working, then additional pest control methods would be employed, such as targeted spraying of pesticides. Broadcast spraying of non-specific pesticides is a last resort. Do most growers use IPM? With these steps, IPM is best described as a continuum. Many, if not most, agricultural growers identify their pests before spraying. A smaller subset of growers uses less risky pesticides such as pheromones. All these growers are on the IPM continuum. The goal is to move growers further along the continuum to using all appropriate IPM techniques. How do you know if the food you buy is grown using IPM? In most cases, food grown using IPM practices is not identified in the marketplace like organic food. There is no AgriKultuur |AgriCulture national certification for growers using IPM, as the United States Department of Agriculture has developed for organic foods. Since IPM is a complex pest control process, not merely a series of practices, it is impossible to use one IPM definition for all foods and all areas of the country. Many individual commodity growers, for such crop as potatoes and strawberries, are working to define what IPM means for their crop and region, and IPM-labelled foods are available in limited areas. With definitions, growers could begin to market more of their products as IPM-Grown, giving consumers another choice in their food purchases. If I grow my own fruits and vegetables, can I practice IPM in my garden? Yes, the same principles used by large farms can be applied to your own garden by following the four-tiered approach outlined above. For more specific information on practicing IPM in your garden, you can contact your state Extension Services for the services of a Master Gardener.
