Technical Abstract: Pesticides exert a selection pressure on pest populations and pests that are not controlled may produce progeny with genetic resistance to the pesticide. Pesticide classification systems based on site/mode of action have been developed and knowing a pesticides’s mode/site of action is key to planning effective resistance management strategies. Growers should select pesticides with different modes of action and not use pesticides with the same mode of action every year in the crop rotation to slow the development of pesticide resistant pest populations. Tank mixing pesticides with different mode of actions can also the development of pest resistance. Pests resistant to different pesticides with the same mode of action are termed cross-resistant. Multiple resistance occurs when pests are resistant to two or more pesticides with different modes of action. Utilizing other pest control practices, such as sanitation or cultivation will help delay buildup of pesticide resistant pest populations. Preventing seed production of annual weeds that escape herbicide treatments is the surest way to prevent build up of herbicide resistant weed populations. Recognizing pesticide resistance, factors affecting pesticide resistance, and resistance management are discussed.
