Ho Ho Holy Cow its going to be cold (in other parts of the country) this holiday break.
Winter and the New Year are great times to think about preventing weed management problems. With the onset of winter rains in many parts of California, weeds have emerged on roadsides, wildlands and the edges of fields. Its a good time to monitor what has emerged and decide if those weeds will need to be treated soon.
Preventing weeds also requires preventing the breakdown of application equipment. We can’t prevent every malfunction, but keeping equipment in good working condition is a good practice. Winter is an excellent time to winterize equipment (as the name suggests) and to also repair any...

My title is Regional Advisor – Invasive Plants, but I really think of myself as a Weed Scientist (which sometimes gets an interesting response from some people; those that likely have a smoking habit).
Weed is a simple word; everyone knows the word and has an idea of what it is referring to, right? It’s a plant that someone doesn’t like for some reason. Or perhaps it is a plant existing somewhere it doesn’t belong. The definition that the Weed Science Society of America (yes there really is a Weed Science Society of America, and no they do not do research on “WEED”) uses is, “any plant that is objectionable or...

From Stephen Powles (Australia)
Attached are details on a good opportunity for a scientist focused on crop-weed issues in the Northern cropping zone of Australia. This is a University of Queensland position, in an initiative known as QAAFI. The appointee will lead a small team based at the beautiful small city of Toowoomba, Queensland. I consider that this is a good opportunity for a mid-career scientist or an...

Prior to the latter half of the 20th century, weed control in agriculture was achieved almost exclusively through mechanical means (e.g. plowing, cultivating, disking, hoeing, and hand-pulling) (Timmons 1970). The earliest (mid-1800’s to mid-1900’s) investigations into chemical weed management focused, primarily, on the use of inorganic compounds such as sodium chloride, sulfuric acid, sodium arsenite, and copper- and iron-sulfate (Appleby 2005; Timmons 1970). Although some products provided an acceptable level of weed control efficacy, the extensive adoption of these chemicals was decidedly limited (Appleby 2005; Timmons 1970).
The successful debut of 2,4-D (1946), an auxinic compound...
