Dr. Nevin Lawrence

About

Nevin directs the weed management research and extension program for the Panhandle region of Nebraska. My research and extension focus is the development of weed management programs that leverage crop rotations and other cultural practices to supplement the sometimes limited weed control options available in Western Nebraska. Specific projects include controlling herbicide-resistant kochia and pigweed species using multi-year integrated management plans, integrating cover-crops into crop rotations where establishment opportunities are limited, and developing tools to assist stakeholders with modeling the economic costs of using diversified herbicide-based weed management plans. Non-crop research and extension projects include the management of invasive weeds in rangeland.

Professional Responsibilities and Activities

• Research Interests
  
  Early season weed control in no-till production fields
  Emergence dynamics and interference of nightshade with dry beans
  Managing herbicide-resistant and difficult to control weeds through crop rotation and other cultural practices
  Control of invasive and undesirable weeds in rangeland and natural areas
  The impact of drought and climate instability on weed communities
• Extension Interests
  
  Providing growers with the latest information on herbicide efficacy, application technology, adjuvant use, and rotation restrictions for Western Nebraska
  Developing applications and web resources to help growers choose herbicide options that balance efficacy, resistance management, and input costs
  Designing weed control programs that work within the herbicide rotation restrictions, high pH soils, and unique the climate of Western Nebraska
  Demonstrate the value of diverse crop rotations to disrupt weed life cycles and delay the development of herbicide resistance weeds
