In alphabetical order:
Isabelle Aicklen (2)
Isabelle Aicklen is currently working on her Ph.D. project, which focuses on confirming and characterizing MCPA resistance in green pigweed at both the physiological and molecular levels. In 2022, she published two papers that describe the response of MCPA-resistant green pigweed in corn and soybeans, which will be included as separate chapters in her thesis. These papers highlight the effects of the resistant weed on Ontario's two most significant field crops and provide a foundation for future experiments. Although the resistance to MCPA and other auxinic herbicides can limit the choices available to farmers, there are still alternative solutions.

Meghan Dilliott (5)
The focus of Meghan’s research was on improving the level and consistency of multiple-herbicide-resistant Canada fleabane control in soybean. The addition of saflufenacil to 2,4-D ester, halauxifen-methyl, dicamba, or pyraflufen-ethyl/2,4-D improved the level and consistency of multiple-herbicide-resistant Canada fleabane in soybean. The addition of saflufenacil or dicamba to bromoxynil improved the level and consistency of multiple-herbicide-resistant Canada fleabane control. The addition of saflufenacil to dicamba improved the level and consistency of multiple-herbicide-resistant Canada fleabane control in Roundup Xtend soybean. Glufosinate did not provide acceptable control of multiple-herbicide-resistant Canada fleabane; the addition of metribuzin of dicamba improved the level and consistency of control. The addition of a PPO-inhibiting herbicide to glufosinate does not improve multiple-herbicide-resistant Canada fleabane control.
The addition of very low rates of PPO-inhibiting herbicides to glufosinate does not improve the control of GR Canada fleabane. Weed Technology 36:358-367.

James Ferrier (2)
James Ferrier studied the control of multiple-herbicide-resistant waterhemp control with pyroxasulfone and flumioxazin. The predicted doses of pyroxasulfone and flumioxazin for 80% control 8 weeks after application are 110 and 80 g/ha, respectively. The co-application of pyroxasulfone and flumioxazin resulted in a synergistic improvement shortly after waterhemp emergence; however, by mid-season the interaction was additive. Pyroxasulfone/flumioxazin caused transient soybean injury.

John Fluttert (7)
John published seven manuscripts from his MSc thesis research! The goal of John’s research was to refine the recommendations for weed control in corn with tolpyralate. John identified Merge as the best adjuvant to apply with tolpyralate, tolpyralate + atrazine, and tolpyralate + bromoxynil. The co-application of tolpyralate with reactive oxygen species generating herbicides (atrazine, bromoxynil or glufosinate) results in an additive or synergistic improvement in weed control.

Mohsen Hesami (4)
These publications represent comprehensive reviews on various aspects of cannabis cultivation and biotechnology. Together, they lay the groundwork to identify gaps in out current understanding and guide future research efforts in the cannabis space. This directly contributes to Mohsen's thesis where he is studying the epigenetic changes that occur in cannabis plants during growth and various biotechnological processes. They represent outstanding publications in a new and exciting field.

Teles Marie (1)
Telesphore Marie is currently completing his Ph.D. project testing a core hypothesis that is outlined in his paper published in Frontiers in 2022. His thesis examines the importance of deploying supplementary lighting systems, specifically those using LEDs (light-emitting-diodes) to enhance year-round production of two of Canada's major greenhouse, vegetable crops (i.e., tomatoes and cucumbers). In the perspective paper he shows that the time of application of specific light cues such as a shift in spectral quality and intensity can be used to alter crop development patterns. His article significantly extends our understanding of how LEDs systems can be deployed to alter natural circadian rhythms associated with primary metabolism associated with photosynthesis and respiration and further how such cues can be used economically to entrain tomato crop development patterns year-round.

Marco Pepe (2)
These publications represent the development of a system to study plant carbon relationships in plant tissue culture using cannabis and tomatoes as model organisms. This platform has the capability of quantifying photosynthesis and respiration at the single plant level, which will help conduct high throughput studies on various aspects of plant growth and development. In his thesis, Marco will use these techniques to further investigate in vitro plant and fungal growth to further our understanding of carbon relationships and establish improved in vitro systems.

Hannah Symington (2)
Hannah completed her research on determining the “fit” of acetochlor for weed management in corn, soybean, and dry bean in Ontario. There is an adequate margin of crop safety in Phaseolus vulgaris market classes of dry beans to acetochlor applied preplant incorporated; in contrast, acetochlor causes unacceptable crop injury in azuki beans (Vigna angularis). Acetochlor tankmixes applied preemergence in corn and soybean provide excellent control of multiple-herbicide-resistant waterhemp. Of the Group 15 herbicides evaluated, pyroxasulfone provides the longest residual control of multiple-herbicide-resistant waterhemp.

Nicole Unterlander (1)
Nicole's thesis studied the link between flavanol catabolism and senescence-related processes in plants. Nicole's recently published an article in Planta that represents the first data chapter from her thesis. As a first author on the paper, most of the experimentation, data analysis and writing of the manuscript was performed by Nicole. The study presents evidence for degradation of flavonol rhamnosides, specifically those of the kaempferol type in ageing leaves of two crucifer family plants Arabidopsis and radish, including during postharvest storage of radish. Moreover, Nicole established evidence for an enzymatic basis for the catabolism of kaempferol rhamnosides in these plants, which has improved our understanding of the link between flavanol metabolism and senescence in plants.
