Around 10 years ago, in the fierce heat of the Kansas summer, many of the noxious kochia weeds invading Phillip Stahlman's research fields simply wouldn't budge when sprayed with a mixture of two.../h5>/h3>/h2>

Weed Science-Based Summer Scholars Opportunity at Cornell University
Guess what, undergraduates! Cornell AgriTech in Geneva has received the green light to proceed with the 2021 season of the Summer Scholars Research Program, which offers students the opportunity to work with faculty, their graduate students and postdocs, and staff on horticulture, plant pathology, and entomology research projects. The goal of the program is to provide undergraduates with the opportunity to plan and conduct experiments, evaluate data, communicate results, and learn about opportunities in agricultural and food research.

However, once I started visiting fields, it quickly became apparent that this was not late watergrass (phenotypically-speaking). It also did not appear to be barnyardgrass (Echinochloa crus-galli), although the Echinochloa species are notoriously difficult to identify, and phenotypically quite variable in...
