While conducting a field experiment testing herbicides for control of sahara mustard in Borrego Springs in 2011, out of a corner of my eye I saw a ring of rusty brown around an ant hole.
Being curious I looked closer. It was an organized mound that was maybe 1 inch high and 3 inches across of redstem filaree (Erodium cicutarium) fruit. It was exclusively filaree, nothing else.
So I explored a little more on my knees and saw these small black ants a foot or so away on a well-beaten trail. Most of the ants had a filaree fruit in its mouth. I don't know the species of ant, but a quick Google search suggests that it is a species of...

Good news for minor tree crop weed managers - Chateau SW (active ingredient: flumioxazin) recently received a Supplemental Label that allows use in bearing olive and pomegranate orchards.
Flumioxazin is a cornerstone preemergence herbicide for many tree and vine crop weed managers. Prior to this supplemental label approval, it could only be used in non-bearing olive and pomegranate. This allowed time for the manufacturer and the USDA-IR4 program to complete the residue testing neccessary for use in bearing orchards (standard proceedures). I'm glad to see this bearing label as it gives another weed management tool for these increasingly important crops in the state...
