Research Area
- Deployment of a unique treatment threshold in cotton which incorporates the action of beneficial insects (PDF)
- Modification of treatment thresholds in wheat to minimize unnecessary inputs while maintaining yield potential. Thresholds have been modified for control the aphid vectors of barley yellow dwarf virus and armyworm.
- Implementation of a biological control program for spotted knapweed in Arkansas. Current project is the release of two weevils in Arkansas (Larinus minutus and Cyhpocleonus achaetes) already present in the Pacific Northwest.
- Evaluation of the movement of pest and beneficial insects among agricultural, natural and biofuel (canola and switchgrass) crops.
