Hi, my name is José Luiz Dias and I have recently joined the University of California Cooperative Extension (UCCE) team. I am writing this blog with the goal to introduce myself, share some of my previous work experiences, as well as to share some of the short- and long-term goals I plan to implement in my extension and research programs.
Area of work
As a UCCE field crops agronomy and weed management advisor, I plan to work closely with the growers, consultants and industry personnel to develop applied research and extension activities in the Northern San Joaquin Valley (SJV) which includes...

A new year and a new farm advisor in Colusa‐Sutter‐Yuba
Hello, I’m Mark Lundy, a new Agronomy Advisor in Colusa‐Sutter‐Yuba, based out of the Colusa office. With 2014 underway, I wanted to send out a brief note to introduce myself and give a brief sketch of some of the work I’ve initiated since I began in July of 2013.
Where are you from?
I’m from Arizona originally, but I’m starting my 9th year living here in California. For most of that time I’ve lived in or around Davis where I was a graduate student for 6 years and earned an MS in International Agricultural Development and a PhD in Horticulture and Agronomy. Prior to graduate...

A quick post today with information about MSMA herbicides. There has been concern and lack of certainty about the registration status of MSMA and other organic arsenical herbicides. I was forwarded the attached press release and current labels for MSMA 6.6 and MSMA 6 Plus.
For those that may not know, MSMA (monosodium acid methanearsonate)is a product used in cotton, golf courses and sod farms, and rights of way.

Winged primrose willow is an invasive weed that was identified in Butte County rice fields in 2011. Most infestations were along borders of fields and canals; however, this weed can thrive in the flooded environment within rice fields. Winged primrose willow can disperse through seeds and plant fragments floating in the irrigation water and tillage and harvest equipment.
Greenhouse tests showed that winged primrose willow can be controlled with rice herbicides. Early, into-the-water applications of Bolero Ultramax, Cerano or Granite GR effectively killed young plants. Foliar applications of Sandea and...

Abstract: Farmers view weed management and the risk of lower yields as barriers to transition from conventional to organic agriculture. The 3 years of transition before organic certification can be used to implement strategies to suppress weeds and improve soil fertility. The objective of this research was to evaluate the effects of five organic transition strategies on soil quality, weed suppression, and yield of tomato (Solanum lycopersicum) and potato (Solanum tuberosum) in the first year of organic production. The transition strategies included a tilled fallow, nontreated weedy, high diversity prairie mixture, smother crops, and vegetable rotation. Subplots with and without compost application were...
