In the toolbox: the Weedometer

The Weedometer is a tool built by Ed Luschei, a former Department of Agronomy faculty member, using data collected from the Weed Garden at the Arlington Research Station from 1998 until 2001. The Weedometer will chart emergence and flowering times for a wide array of weed species at many locations throughout the United States.

The Weedometer website has detailed instructions for using the tools. The following diagrams provide abbreviated instructions for how to use the Weedometer. Click on the image to make it larger.
