Dr. Knutson develops educational materials and programs on integrated pest management (IPM) of insect pests of cotton, wheat, sorghum, pecans, corn and other crops and supports county extension agents with educational programs in IPM. He serves as statewide coordinator for biological control programs for Extension entomology faculty; develops cooperative programs on biological control and educational materials.

Areas of Expertise:

  • Integrated pest management of major row crops and pecans
  • Biological control of insect pests and weeds
  • Use of pheromones for monitoring and mating disruption
  • Host plant resistance in cotton to plant bugs
  • Sampling methods for beneficial insects in cotton
