Larry P. Pedigo

Professor; Ph.D., Purdue University (1967)

Department Position: 50% research, 50% teaching

Dr. Pedigo's research seeks to improve pest management in Iowa field crops through a comprehensive understanding of crop-plant response to stress caused by insects and other pests. His primary focus is soybean and alfalfa ecosystems. His major emphasis is developing sound economic thresholds and pest-sampling programs for grower-based management decisions. A companion effort is the development of management tactics that reduce pesticide use and provide economic advantages.

Recommendations from IPM research on this project have emphasized pest economic thresholds and pest population monitoring, thus reducing pesticide inputs, improving grower profits, and conserving environmental quality. Additionally, research focuses on pest-resistant cultivars, pest complexes in transgenic soybean systems, and site-specific management, which will improve the decision-making capabilities of Iowa farmers. Alternative management tactics developed from this research will allow growers to establish sustainable farming practices that are economically acceptable and environmentally compatible.
