Integrated pest management systems: rationale, objectives, and design
The objective of the project was to develop integrated crop management systems for weed, insect and disease populations and evaluate the efficacy and cost/benefit of the various management practices. The strategy of integrated management of crop pests seeks to understand the factors that influence changes in pest populations and to utilize these factors to regulate population levels. Field experiments were established in the fall of 1996 on the Kernen Crop Research Farm at the University of Saskatchewan and on the Agricultural Research and Development Farm of Saskatchewan Wheat Pool at Watrous. Six systems were based on combinations of tillage and herbicide inputs. A four-year crop rotation of wheat, canola, barley and field pea was used from 1997 to 2000. Agronomic and pest population data were collected yearly. The economics and energy efficiency of the six systems were compared. Carabid beetle diversity was used as an assessment of soil health.
