Plant Pathology Extension

Addressing diseases that threaten grain and vegetable production across the Texas High Plains

Extension Services, Diagnostics, and Applied Research Against Plant Disease Threats

Plant pathology extension programs at Amarillo revolve around delivering plant disease control and management solutions that are based on applied research. Our work focuses primarily on grain and vegetable crops produced in the Texas High Plains, which continue to face challenges from old and new diseases. Management solutions developed by the plant pathology program at Amarillo are informed by field trials and experiments to characterize plant pathogens and the diseases they cause.

Our work to deliver plant disease management solutions includes:

  • Applied Research
  • Operation of the Texas High Plains Plant Disease Diagnostic Laboratory
  • Training of agents
  • Coordination with producers and producer groups
  • Dissemination of plant disease fact sheets
