My research program at Washington State University is focused on basic aspects of weed biology and ecology with the goal of integrating such information into practical and economical methods of managing weeds in the environment. Currently, ongoing projects include physiological, biological and ecological studies on prickly lettuce, a common and troublesome weed in crops, range, and noncropland throughout the inland Pacific Northwest. Prickly lettuce is an invasive weed with wind dispersed seeds that crosses boundaries at multiple scales – from field borders to regional boundaries. It infests Conservation Reserve Program (CRP) land and appears to cause significant economic losses in wheat-based cropping systems. Future research will focus on improving understanding of the biology of this species and the implications of control inputs in different adjacent managed ecosystems (wheat and CRP). This project will test the hypothesis that weed control practices resulting from policy directed economic limitations in CRP will have a direct effect on production practices and profitability in adjacent agroecosystems. Those same control practices may have also have contributed to the development of herbicide resistance. To test this hypothesis, the effects of policy-induced prickly lettuce control practices in CRP on fecundity in response to typical (low) input versus effective (high) input, seed movement and seed rain dynamics to adjacent crop ground that result from those inputs, and density-dependent yield losses (and thus the economic costs) based on seed production in crops and seed movement out of CRP and into adjacent crop fields. This information would allow more accurate guidance for policy makers and growers on how to manage this destructive weed for the benefit of both ecosystems.

Other projects include an assessment of the changes in the soil seed bank in response to 8 years of crop rotation at the Cook Agronomy Farm, biological and physiological aspects ofArtemisia annua cultivation in eastern Washington, and physiological and biochemical investigations with aminocyclopyrachlor, a new growth regulator type herbicide.
