Two unique workshops on soil quality will be provided this week. One will be held on Tuesday,
December 10, 2013, on the UC Davis campus in 3001 PES (Physical and Environmental Sciences) at 11:00 am and the other will take place in Five Points on Wednesday, December 11, s013, also at 11:00 am.
The sessions will feature Brendon Rockey, a farmer from Center, CO and Jay Fuhrer, an NRCS District Conservationist from Bismarck, ND. They’ll be leading the workshop that will also include a lunch and a follow-up discussion.
For further information, please contact Jeff Mitchell, CE Cropping Systems Specialist, Kearney Agricultural Research & Extension Center, at (559) 303-9689 or firstname.lastname@example.org.
'Biotic farming' considers all living things, not just the crop being grown.

Daane and his research associates followed moth populations in organic and conventional fields to document this observed change and determine if there were any specific causes for increases in raisin moth densities. In a 2013 season study, UC Kearney Agricultural Research and Extension Center entomologists found that spring to early summer pheromone trap catches of raisin moths were prevalent across numerous vineyards, regardless of management practices. However, overall seasonal damage in 2013 was low.
“The primary difference between vineyard sites with or without raisin moth damage appeared to be well-timed and effective insecticide sprays,” Daane said. “One problem for organic sites may be the availability of insecticide materials that have long enough residual activity to control the larvae of adult moths entering the vineyard, and once the larvae are deep inside the grape cluster they are difficult to control.”
In addition to Daane’s report, the San Joaquin Valley Grape Symposium includes the following research updates:
- Rootstocks for raisin production by Sonet Von Zyl, Fresno State University
- Raisin production canopy management by Matthew Fidelibus, UC Cooperative Extension specialist in the Department of Viticulture and Enology at UC Davis, based at the UC Kearney Ag REC in Parlier
- Raisin grape breeding program by Craig Ledbetter, USDA Agricultural Research Service, based in Parlier
- Economics of producing raisins, by Annette Levi, Fresno State University
- Grapevine trunk diseases and grower survey
The symposium begins with registration at 7 a.m. and concludes following lunch at 1 p.m. at the C.P.D.E.S. Hall, 172 W. Jefferson Ave., Easton, Calif.
Registration is $15 in advance and includes lunch. Registration at the door is $20. To preregister, send the names of attendees and a check payable to UC Regents for $15 each to San Joaquin Valley Grape Symposium, 550 E. Shaw Ave., Suite 210-B, Fresno, CA 93710.
