Weed Science Research

We have been conducting field and greenhouse research at the Leyendecker Plant Science Research Center since 1988. Research has included field evaluations of candidate herbicides for use in chile pepper, onion, cotton, grain sorghum, corn, and pecans; determination of the economic benefit of herbicides and cultivation for weed management in chile pepper; effect of weeds on yield and quality of chile pepper; and growth characteristics of some of the problem weeds found in southern New Mexico production systems. The research has defined the problems that weeds pose in production agriculture in New Mexico and has provided information concerning the effectiveness of herbicides in our soils and under our environmental conditions.

This research program has sponsored undergraduate and graduate student research projects each year. Many of the students conducting research projects in this program have had the opportunity to present the results of their work at a professional meeting. Working in our program offers students an opportunity to participate actively in interdisciplinary research; students have the chance to experience how to work collaboratively with groups on project and methods development, design, analysis, and interpretation of data. In addition, we maintain a weed garden for use by students taking the weed science classes at NMSU, other programs in the college, and the public.

Current projects are mostly collaborative efforts with other scientists in the Entomology, Plant Pathology, and Weed Science and Plant and Environmental Sciences Departments. The current work can be separated into two broad areas: the interaction between weeds and other pests that are problematic in chile pepper and rotation crops and a project under the Rio Grande Basin Initiative.
