Research Interest

The goal of my research program is to develop weed management strategies that are applicable and appropriate for agricultural systems in the southwestern United States. To accomplish this goal, my students and I study weed and crop responses to combinations of tactics including herbicides and cultural practices. Through diversification, we aim to make weed management programs more reliable, more cost-effective in the long-term, and less threatening to non-target organisms.

Highlights from Specific Projects

  • New herbicides for specialty crops. Chile pepper and onion have few herbicide options compared to other crops commonly grown in New Mexico. To increase the number of herbicides available for chile pepper and onion, we conduct studies that support local registrations for new herbicides. Our goal is to identify herbicides with greater efficacy, lower cost, and lower risk to the environment than currently registered herbicides. For more information on a preliminary project that guided current herbicide studies in onion, please click here.

  • Weed seedbank management. For many weed species, reserves of seeds in soil (i.e., seedbanks) enable population persistence and increase management costs. Accordingly, tactics that target seedbanks are critical components of successful weed management programs. To communicate the importance of weed seedbank management, we developed an interactive, educational model that allows farmers and consultants to better understand ecological and economic implications of weed seeds in New Mexico chile pepper production. The educational model can be found in the .zip file below.
