The US Manager of BCI, the Better Cotton Initiative, Scott Exo, and BCI's San Joaquin Valley Coordinator, Carlos Silva, visited the longstanding NRI Project field in Five Points, CA on March 28, 2017 as part of a tour hosted by CASI's Jeff Mitchell. BCI is a not-for-profit organization that encourages a holistic approach to sustainable and brings together people who are involved in cotton's complex supply chain, - from farmers to retailers. Initiated in 2005, BCI exists to make global cotton production “better for the people who produce it, better for the environment it grows in and better for the sector's future, by developing Better Cotton as a sustainable mainstream commodity.” Exo and Silva visited the NRI Project field to learn about the work that has been done over the years on cotton production in this field using no-tillage and cover crop practices and the benefits that stem from the use of these approaches in lower costs, fewer dust emissions, greater carbon and nitrogen storage in the soil, increased soil aggregation and water infiltration, reduced soil water evaporation, and other positive changes in soil biology that have been documented since the project was started in 1999. They also discussed with Mitchell the California Farm Demonstration Network, a broad group of partners who are working throughout the State on establishing local farm demonstrations of improved performance, conservation ag, climate-smart and healthy soils systems, and BCI's potential involvement in the network as a partner.

Abstract: The psyllid Diaphorina citri is the vector of the bacteria associated with huanglongbing (HLB), which is the most destructive citrus disease worldwide. Chemical control is the primary tactic against this insect. However, alternative methods are important to achieve a more effective control in an integrated pest management programs. Thus, this research was carried out to assess the influence of different kaolin formulations on the settling and probing behavior of D. citri. In both studies, two wettable powder (WP) kaolin formulations (Tessenderlo Kerley, Inc./NovaSource) were sprayed three times at different concentrations on sweet orange plants. In the experiment to assess the settling behavior, three concentrations (3, 5 and 7% w/v) of both formulations were tested. A non-choice test was performed, where 16 adult psyllids were released in a cage with seedlings of the same treatment, and the number of psyllids/plant at different time intervals was counted. For the probing trial, the electrical penetration graph (EPG) technique was used. Adult psyllids were monitored for 6 h on nursery citrus trees treated with two kaolin formulations at 3 and 5% w/v. The two kaolin formulations have a repellent effect on D. citri, causing an overall reduction of 40% of psyllids settled on treated seedlings compared with untreated control. Moreover, both formulations disrupt D. citri probing behavior, with a significant reduction (60%) in the proportion of psyllids that reach the phloem compared with untreated nursery citrus trees. In general, there were no differences between the kaolin formulations and among the concentrations tested in both experiments (settling and probing). Then, both formulations could be used in an integrated D. citri management program. These findings reinforce the recommendation of kaolin application on young citrus planting as a useful strategy for HLB management, mainly on the edge of the farms.

The deadline for submitting nominations for the ANR Staff Appreciation and Recognition (STAR) program for the fiscal year 2016-17 has been extended to April 3.
The program provides cash awards to eligible staff in recognition of outstanding achievement. Managers may nominate individuals and teams demonstrating exceptional performance, creativity, organizational abilities, work success and teamwork.
ANR staff in PSS and MSP titles, as well as members of the Clerical Unit (CX), are eligible to be nominated for cash awards. Nomination forms and program guidelines are attached. To simplify the process, we've streamlined the nomination form.
Send your nominations to firstname.lastname@example.org. The deadline to submit is Monday, April 3.
The purpose of the STAR program is to recognize and reward outstanding staff individual and team performance within Agriculture and Natural Resources.
Under the STAR plan, managers can recognize, acknowledge and reward staff employees for exceptional performance or significant contributions related to and supportive of individual, departmental, divisional or organizational goals and objectives.
A review committee will review the applications and recommend up to 20 individuals and two teams to the vice president, who has authority to approve STAR awards. Individuals who are eligible may receive cash awards of $1,250. For teams of 12 or fewer, team members may receive $1,000. Teams of 13 or more will share $12,000. Some restrictions may apply to eligibility for cash awards.
STAR Awards will be celebrated during an ANR recognition event at the Second Street building in Davis.
