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).

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:

I'm sure you've noticed that different years have dominant weed species. For example this year in Southern California Russian thistle (aka tumbleweed Salsola tragus among other Salsola species) is abundant in many areas. Other years it is only moderately abundant and some years it seems to hardly hang on. The obvious question is why? Why is there so much variation in abundance between years?
Fortunately for us people have been working on this issue for a while and have a few general answers for us. Since the bulk of weeds in California are annuals I'll limit my discussion to those plants.
The seeds of annuals germinate only under a certain range of environmental conditions....
