Kassim Al-Khatib, Director of the UC-Statewide Integrated Pest Management (UC-IPM) Program, sent a couple links about the identification of Palmer amaranth and comparison to other amaranth (pigweed) species. I thought they were useful and potentially of interest to California weed managers so I thought I'd share:
In this first link, Dr Bill Johnson and Travis Legleiter, weed scientists from Purdue University have a video explanation for helping growers identify Palmer amaranth and explain differences between other related species in Indiana (click here for...

Rather than applying herbicides, try a cover crop to prevent weeds in anchor rows.
Cover crops in anchor rows can suppress weed growth and additionally help to minimize soil erosion and nutrient and sediment loss when it rains. Densely planted cover crops can outcompete weed seedlings germinating from the soil and prevent wind-dispersed seeds from reaching the wet soil surface. Check out the newly revised weed section in the Caneberries Pest Management Guidelines on the UC IPM web site.
Caneberry growing tunnels have the advantage that even when it rains caneberries remain dry. This helps with disease prevention and assures fruit quality. However,...

This is the third in my series of posts outlining current University of California weed science research published in the California Weed Science Society (CWSS) Research Update and News (June 2013, Volume 9, #2).
Kurt Hembree and Tom Turini (both UCCE Farm Advisors in Fresno Co) discuss some issues related to herbicide persistence and crop safety in processing tomato that appears to be related to changing irrigation practices. Historically, tomato crops were sprinkler irrigated after...

A repost of an article by Luis Espino (UCCE Farm Advisor, Colusa Co) on the UC Rice Blog.
You can see the originl post HERE
He also had a post on a similar topic earlier HERE that had some results from Albert Fischer and Jim Eckert's research on smallflower umbrella sedge.
