At a meeting yesterday, Joe DiTomaso mentioned a new book: The Weed Agency written by Jim Geraghty.
I wonder if it's anything like Curse of the Giant Hogweed (Peter Shandy Mysteries) by /span>

Joe DiTomaso and I, with several other coauthors, have almost finished the “Medusahead Management Guide for the Western States.” This project is supported by a grant from Western IPM. In requesting funding for this project, we noted that
- Medusahead is a problem both on low-elevation foothill rangeland and in Great Basin ecosystems, and management is very different in these two regions. As a result, there is often confusion about the best management strategies for different areas.
- Each of the coauthors is asked to give several talks per year on medusahead control to growers' meetings in and out of state.
- There hasn't been a comprehensive, multi-state guide for growers recently, if ever, and...

Hand weeding is undoubtedly the oldest method of weed control, as old as agriculture itself. The weed uprooted by hand pulling or with a hoe dies from desiccation. If a hoe were an herbicide (in reality a hoe is a pest control device), the active ingredient would be steel, and the mechanism of action would be cell collapse from lack of water. There are exceptions like common purslane and bermudagrass which will survive uprooting and can survive to re-root in a new location.
Hand weeding is an effective method of weed control, and in normal commercial practice weed control of over 90% can be achieved. If two trips are made through the field near 100% weed control can be achieved. However, hand weeding is expensive...

In this case that means educating land managers and related professionals on how to efficiently and accurately apply herbicides to large areas. That's what the Cooperative Mule is all about, so sit back, I hope...

Tips on applying herbicides
The table below is from training that my colleagues Dr. Cheryl Wilen, Area Advisor, UC IPM; Dr. Milt McGiffen, Extension Specialist, UC Riverside; and I did in southern California at four locations in 2009/2010 with a total of 80 people that all had previous experience applying herbicides on invasive plants. This training utilized the 128th acre sprayer calibration method (more on that below).
