A few months ago I wrote about starting some tests looking at various postemergence herbicides for non-crop use. This project was initiated due to new ordinances some cities in southern California were considering or adopted that limited the use products containing glyphosate on city owned property.

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.
NOMENCLATURE:
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...
