Research (30%) - Small grains, soybeans, corn, and cotton
My lab's research objectives include the improvement and expansion of integrated pest management practices and knowledge for insect pests of field crops. This focuses on four broad areas:
1. Evaluation and establishment of sampling procedures for estimating pest abundance in major field crops.
2. Evaluation and establishment of economic thresholds for major and emerging pests of corn, wheat, soybean, and cotton.
3. Evaluation of insecticides and alternative management tactics (e.g. varietal tolerance, planting dates, and other cultural, physical, and mechanical tactics) to minimize insect damage and environmental impacts.
4. Developing integrated pest management practices on various spatial and temporal scales using global positioning system (GPS) and geographic information system (GIS) technologies.
I also wish to characterize important biological and ecological factors of arthropod pests and associated organisms of field crops, including the delineation of pest flow through major and minor agricultural crops.
Extension (70%)- Small grains, soybeans, corn, and cotton
Field crops are vital to North Carolina’s economy and are grown throughout the state. They represent a significant part of land dedicated to agriculture in the state. Consequently, management decisions for these crops have wide-ranging systemic effects on the state. Increasing urbanization and recent changes in agronomic practices within and among crops have affected which insects are pests and how these pests are managed. My goal in extension is to bring relevant, timely and scientifically based information and solutions to North Carolina's field crop producers. I strive to harmonize producer concerns with environmental impacts and the general public's needs, with the overarching goal of enhancing the profitability and efficiency of field crop production in the state.
