About

Professor Adam S. Davis is a Professor and Head of the Department of Crop Sciences at the University of Illinois. He currently serves as the Head of Department and is not taking on new lab group members during this period. His research group has focused on various aspects of crop sciences, including weed management, herbicide resistance, soil nutrient provisioning, and sustainable intensification of production agriculture. The group has produced numerous alumni who have pursued careers in academia, research, and applied agricultural sciences, reflecting the broad impact of his mentorship and research. Professor Davis's work encompasses participatory research, extension services, and the application of hierarchical models to understand herbicide resistance evolution, contributing significantly to the field of crop sciences and agricultural sustainability.

• Extending Plant Defense Theory to Seeds

  Annual Review of Ecology Evolution and Systematics · 2020 · 104 citations

  Plant defense theory explores how plants invest in defenses against natural enemies but has focused primarily on the traits expressed by juvenile and mature plants. Here we describe the diverse ways in which seeds are chemically and physically defended. We suggest that through associations with other traits, seeds are likely to exhibit defense syndromes that reflect constraints or trade-offs imposed by selection to attract dispersers, enable effective dispersal, ensure appropriate timing of seed…

• Seed-shattering phenology at soybean harvest of economically important weeds in multiple regions of the United States. Part 1: Broadleaf species

  Weed Science · 2020 · 33 citations

  Abstract Potential effectiveness of harvest weed seed control (HWSC) systems depends upon seed shatter of the target weed species at crop maturity, enabling its collection and processing at crop harvest. However, seed retention likely is influenced by agroecological and environmental factors. In 2016 and 2017, we assessed seed-shatter phenology in 13 economically important broadleaf weed species in soybean [ Glycine max (L.) Merr.] from crop physiological maturity to 4 wk after physiological mat…

• The critical period for weed seed control: A proposed framework to limit weed seed return

  Weed Research · 2021-05-20 · 28 citations

  articleOpen accessSenior author

  Abstract Proliferation of herbicide‐resistant weeds demands re‐evaluation of fundamental weed control objectives. Yield loss mitigation remains a priority, but limiting weed seed return (WSR) to the soil seedbank is key to preventing herbicide‐resistant annual weeds from multiplying. The critical period for weed seed control (CPWSC) is the period of the growing season during which weed control can minimise weed seed production. The CPWSC provides a framework to limit WSR by targeting weeds durin…

• Metabolic Pathways for<i>S</i>-Metolachlor Detoxification Differ Between Tolerant Corn and Multiple-Resistant Waterhemp

  Plant and Cell Physiology · 2021 · 27 citations

  Abstract Herbicide resistance in weeds can be conferred by target-site and/or non-target-site mechanisms, such as rapid metabolic detoxification. Resistance to the very-long-chain fatty acid–inhibiting herbicide, S-metolachlor, in multiple herbicide-resistant populations (CHR and SIR) of waterhemp (Amaranthus tuberculatus) is conferred by rapid metabolism compared with sensitive populations. However, enzymatic pathways for S-metolachlor metabolism in waterhemp are unknown. Enzyme assays using S-…

  Pest Management Science · 2020 · 27 citations

  BACKGROUND: Two waterhemp (Amaranthus tuberculatus) populations from Illinois demonstrating multiple-resistance to acetolactate synthase (ALS)-, 4-hydroxyphenylpyruvate dioxygenase, and photosystem II (PSII)-inhibiting herbicides (designated CHR and SIR) also displayed reduced sensitivity to very-long-chain fatty acid-inhibiting herbicides, including S-metolachlor. We hypothesized that a physiological mechanism, such as enhanced metabolism, could be responsible for the reduced efficacy of S-meto…
