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...

This training utilized the 128th acre sprayer calibration method (more on that below).

I thought I'd make a quick post today to share links to several recent articles in the trade publication "CAPCA Advisor". This magazine is targeted towards Pest Control Advisors (CAPCA = California Association of Pest Control Advisors) and is published every two months. Most issues of CAPCA Advisor have at least one article written by UC Cooperative Extension pest control researchers.
The magazine has a nice web interface with the last 12 issues of the magazine and here are links to four reports by UC weed science researchers:
