2023 Dry Bean Field Day Agenda
- Author: Michelle Leinfelder-Miles
Diagnosing problems in the field is never an easy task, but it is one of the most interesting aspects of my job because I usually never encounter the same set of circumstances twice. This summer, I have been called out on a few interesting diagnostics calls, and I wanted to share some observations.
I visited a blackeye bean field that was planted at the end of June. Since June was unusually cool this year, the grower's planting was delayed. Blackeyes shouldn't be planted until the soil temperature reaches at least 65 degrees F, and the cool spring conditions kept the soil cool. About six days after planting, the beans were only sporadically emerged. The plants that had emerged looked healthy, but the overall stand was poor. The grower said that soil moisture was good at the time of planting. I scratched down and found the seed about three inches deep, which is perhaps a little bit deep for blackeyes. Seed had germinated, and the germinated seed looked healthy with no apparent seedling diseases. Seedling diseases include Pythium and Rhizoctonia. Pythium symptoms appear as water-soaked lesions, and the hypocotyl eventually ‘dampens off'. Rhizoctonia symptoms appear as reddish-brown lesions that can girdle the stem. We felt better that it didn't appear to be a disease problem. I reached out to my farm advisor colleague, Rachael Long, to get her take on the situation, and she agreed that this was likely delayed emergence due to cool soil and a deeper planting depth. In the end, we decided to test our patience, wait a few more days, and see what would happen. After another five days, the grower let me know that the plants had emerged, and the stand looked good!
The UCCE network has a breadth of experience to help identify problems and provide potential management solutions. Please don't hesitate to contact me if you'd like help with diagnosing problems in the field.

Dry Bean Field Day Agenda
- Author: Michelle Leinfelder-Miles
UC Davis and UC Cooperative Extension will host the UC Dry Bean Field Day on Thursday, September 1, 2022 from 9:00am to 11:00am. The field day will begin at the Campbell Tract on the UC Davis campus, which is a different location from where it has been in recent years. The agenda is pasted below, and a downloadable version is attached to the bottom of this post. CCA continuing education credits have been requested (2.0 units of Crop Management). Thanks for your interest, and we hope to see you at the field day!
Agenda:
Attendees are invited to venture into the fields to look at the lima breeding materials, cooperative dry bean nursery, and heirloom-like dry beans at the student farm (38.541667, -121.767111), with Travis Parker, UC Davis
UC Dry Bean Field Day Agenda

I am pleased to announce the following meetings and webinars.
1. The Rice Experiment Station (RES) Annual Field Day will takes place next Wednesday, August 25, 2021 from 7:30am to 12:00pm, followed by lunch. The RES is located at 955 Butte City Highway (Hwy. 162), approximately two and one half miles west of Highway 99, north of Biggs, California. The field day is an opportunity to learn about the research being done at the RES, including variety development. It is sponsored by the California Cooperative Rice Research Foundation (CCRRF) and University of California (UC). For more information, please visit the RES website.
2. Farmers' Rice Cooperative and Wetlands Preservation Foundation will host a Delta Rice Field Day next Thursday, August 26, 2021 from 8:30am to 1:45pm. The event will start at Canal Ranch (23011 Blossom Road, Thornton, CA 95686), followed by a bus tour of nearby Delta rice production. I will be present to answer questions about my rice research and extension program, including the Delta variety trial, armyworm monitoring, herbicide trials, and weedy rice outreach. Space is limited, so please see this flyer to reserve space.
3. The UC Dry Bean Field Day will take place on Tuesday, August 31, 2021 from 9:00am to 11:30am. The field day will begin at Honey Bee Haven, Bee Biology Road, on the UC Davis campus. Due to Covid-19 safety precautions, preregistration for this event is required. There is no registration fee. I invite you to view the agenda and register here. CCA continuing education credits (2.0) are available (0.5 of NM; 0.5 of PM; 1.0 of CM).
4. The UC Alfalfa and Forage Field Day will take place on Thursday, September 23, 2021 from 8:00am to 12:15pm, followed by lunch. The field day will take place at the Kearney Research and Extension Center, 9240 S. Riverbend Ave., Parlier, CA 93648. Due to Covid-19 safety precautions, preregistration for this event is required. There is no registration fee. I invite you to view the agenda and register here. We have applied for DPR, CCA, and N management (ILRP program) continuing education credits.
5. The Vertebrate Pest Council is hosting vertebrate pest webinars on September 28 (field rodents), September 29 (use of rodenticides), and September 30 (managing commensal rodents). The webinars run from 8:00am to 10:00am each day, and registration is required. Please see this flyer for more information.
Finally, the Covid-19 pandemic is a fluid situation. At this time, I plan to hold an in-person field meeting at the Delta field corn variety trial, as I have done in the past. The date is TBD but will take place in late-September or early-October. I will send a separate blog announcement when the date has been set.
Thank you for your interest in our programs. Stay healthy, and hope to see you soon at one of these events.
