Capitol Public Radio broadcast a report on spotted spurge this morning, including an interview with UCCE Farm Advisor Whitney Brim-DeForest.
A few months ago I wrote about starting some tests looking at various postemergence herbicides for non-crop use.

Weeds are easiest to control when they are tiny emerging plants, reported Jeanette Marantos in a Los Angeles Times blog post. Marantos got tips on weed management from Cheryl Wilen, UC Cooperative Extension integrated pest...
After four years of drought, turfgrass has taken a beating. Some people have turned off the water—the turf has turned into a few patches of grass, but mostly weeds, if anything is growing at all (Figure 1.) Others have reduced irrigation amount or frequency resulting in sparse grass and more weeds (often perennial weeds and/or drought tolerant weeds such as bermudagrass, dallisgrass, field bindweed, dandelion, narrow or broadleaf plantain, knotweed, hairy fleabane, star thistle and others.) Other people of course have removed the grass and replaced the landscape without turfgrass. There also has been a concerted effort to get people to reduce the grass in the landscape by painting with a broad brush that grass is a heavy water...

In a recent blog post, Dr. Clyde Elmore discussed weed species changes in urban environments in response to the ongoing drought. One weed that can thrive under dry conditions is field bindweed, a significant weedy pest for homeowners, land managers, and farmers, alike.
Field bindweed was first named by Linnaeus in 1753; its Latin binomial (Convolvulus arvensis) is derived from convolvere ("to roll together") and arvense ("in the field"). Which is pretty appropriate, if you ask me.
Field bindweed is a persistent perennial in...
