All About Glyphosate: An Issue of the Journal 'Pest Management Science' Dedicated to the Active Ingredient

Glyphosate was commercialized in 1974. Since then, it has become one of the most widely used (and studied) herbicides. According to Duke (2018b), almost 20,000 scientific publications and patents have included glyphosate as a focus; only 2,4-D surpasses it with respect to citations. The articles in...

Multiple independent origins of glyphosate resistance in Italian ryegrass

The evolution of herbicide resistance in weeds is an ongoing problem in California agriculture. Resistance to glyphosate has become particularly widespread across the state. Normally, glyphosate kills weedy plants by inhibiting 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), an enzyme that is...

Student research on the temperature effects on glyphosate performance on junglerice

Several researchers in the UCD weed science program have been working on various aspects of glyphosate-resistant junglerice (Echinochloa colona) for the past few years.   One of our undergraduate student interns, presented a poster at the 2018 Plant and Soil Conference (the California...

What junglerice (Echinochloa colona) genes can tell us about glyphosate resistance in California

Each of us have the entire blueprint for our bodies contained in every cell, and the same is true of plants. This information is stored in the form of an extremely long molecule known as DNA (in human cells its length is ~6 feet). Studying and understanding DNA in plants has led to many advances in...
