2) Research and consider potential control options
3) Choose control options and make a plan
4) Implement weed control plan
5) Track results and modify treatments as necessary
6) Maintain weed population control through monitoring and continued control efforts
If one of...

In summer 2015, USDA-ARS and UC Davis Dept of Plant Sciences set up a water hyacinth control study with California Department of Boating & Waterways. The goal of the study was to determine the best of several different surfactants to pair with an aquatic-use formulation of glyphosate.
Aquatic weed trials are tricky compared to terrestrial trials, because the test sites are three-dimensional and they move around. In addition, water hyacinth is free-floating. In order to establish secure test plots, we built floating 1-m2 quadrats out of PVC pipe, swim noodles, and construction fencing.
On 31 July, we anchored the quadrats in open water within a sunken island in the Sacramento delta. Quadrats were...

A recent announcement for the Twentynine Palms (CA) annual weed show got me thinking about how we (okay...I...) view unwanted plants. As a weed scientist, I spend >99% of my time thinking critically about weeds...specifically, their biology, ecology and management. The remainder of the time, I am actually enjoying them as botanical specimens worthy of admiration. In honor of the Twentynine Palms Historical Society's 75th (75th!!!!!) annual weed show (November 7 and 8, 2015), I'm providing you with something completely different...a few of my photographs highlighting weeds in their own unique glory.
Enjoy.
