Dehydrated onions may be at the top of the list, one that also includes alfalfa, sugar beets, carrots, Bermuda grass for seed and hay and Sudan grass for hay – the crops Corky Wycuff is responsible for as farm manager for Ruegger and Ruegger in Westmorland.

Corky has been a GORAB board member since 2006. A 1972 graduate of Cal Poly with an animal science major, his first job was with the Templeton Livestock Market. After three years there he turned to other commodity and career interests, and hasn’t relied on his major since.

He has been with Ruegger and Ruegger for the past 15 years, and a proud resident of Westmorland and the Imperial Valley. He is serving his second term (sixth year) as a member of the Westmorland Union Elementary School District.

emergence and growth of onions.Research support by GORAB focused on the

evaluation of pre-emergence and post emergence herbicides applied at several rates and application timings on two different soil types. Results showed that DCPA (Dacthal) applied post-plant and pendimethalin (Prowl H2O) applied at or before the loop stage reduced kochia, lambsquarters and hairy nightshade density compared to untreated plots. An additive effect occurred when the two herbicides were applied in combination, especially for kochia control.

Wilson’s studies refute a long held belief that Dacthal becomes tied up in the fine textured, high organic matter Tulelake soils. His data show that Dacthal applied

after planting is effective and economical when used at affordable rates in combination with Prowl H2O. Prowl H2O applied at the loop stage worked in most situations, but under heavy kochia pressure,

Rob Wilson, Station Director Tulelake (IREC) discusses weed control at the IREC Field Day

IREC Research Station Manager Rob Wilson emphasized weed control for onions and garlic at the Tulelake station’s annual field day on August 13, part of a full day’s program attended by an enthusiastic group of Allium specialists, growers and researchers.

Wilson’s research, including studies sponsored by GORAB, has focused on control of early emergence weeds such as kochia, common lambsquarters, redroot pigweed and hairy nightshade. Kochia in particular slows the

GORAB took advantage of a timely opportunity to inform several members of various state water boards about critical water needs and growing conditions when it was included in this year’s California Specialty Crops Council (CSCC) tour in July.

Altogether 47 federal and state regulatory personnel took part in the tour. They heard Kevin Lehar of Woolf Farming describe the onion harvesting process underway at a tour stop at Jayne and Lassen Avenues. As the bus continued to Sequoia Packing in Coalinga Lehar teamed with Aubrey Bettencourt to discuss water needs and Westside growing conditions.

Bettencourt, director of the California Water Coalition in Hanford, joined that leg of the tour at GORAB’s invitation. A walk-through of Sequoia Packing, led by Christian Marrione and David Anderson was especially informative.

Further opportunities to discuss the conditions and needs of Westside agriculture and onion and garlic production occurred as the tour group continued through the Salinas Valley, where vegetable and tomato production were emphasized. It showcased other northern valley farming sites and centers, and eventually concluded in Sacramento.

The tour, the opportunities to communicate directly with the participants and the potential for continuing dialogue with those who took part confirms the purpose of CSCC and GORAB’s participation in it. Plans are already underway for next year’s tour, and word is spreading among potential participants about its hands-on educational value.

applications prior to emergence gave the best control with no phytotoxicity.

The GORAB research committee has been working with BASF Corporation to grant a Special Local Need Section 24(c) registration that will allow use before onion emergence and when onion radical development has reached 75 percent. Hope is strong that resolution on this needed use will be available by the 2015 season.

UC Davis Extension Plant Pathologist Mike Davis’s preliminary results show that garlic juice/oil or onion/garlic processing waste can be used effectively as a biostimulant to induce white rot sclerotia germination (without the presence of an Allium crop), followed by a conventional fungicide the next season.

The loss of diallyl disulfide (DADS) as a biostimulant requires that the industry search diligently for a tool to complement conventional fungicides in managing white rot.

Advisory Board Renewal on the DocketAs it completes its tenth year of service and commitment to the onion and garlic industries, it is time for GORAB

to meet one of the important obligations of the California Food and Agriculture Code of holding a continuation hearing every five years, as stated in Chapter 1 of Part 2 of Division 21 of the California Food and Agriculture Code.

The hearing will be held Wednesday, November 12 at the Harris Ranch restaurant in Coalinga beginning at 9:30 a.m. in the Golden Gate Room. A notice to all growers, handlers and processors has been sent. All stakeholders are encouraged to attend and voice their opinions regarding continuation of the market order.

Significant progress has been made through research programs on behalf of both the onion and garlic industries. Future goals include focusing on the development of a white rot management program that utilizes natural by-products of the two industries, including processing waste, culls and garlic juice/oil.

The following statement of GORAB’s core objectives may help members and others attending the hearing determine how well it has maintained its focus.

• Provide a unified voice for all California Allium crops.

• Continue strict adherence to White Rot Master Plan to prevent further spread of the disease.

• Consider new white rot integrated strategies including biotech, biopesticides and cultural control, with emphasis on use of natural biostimulants.

• Develop Thrips Management Plans for the Imperial Valley, San Joaquin Valley and the Tulelake growing areas based upon strategies developed through our research programs.

• Expand scope of Research Board to include all Allium crops, including work with dry bulb industry on an ad hoc basis and with seed production companies on joint objectives.

• Continually update research objectives with input from all of the Allium industry.

• Continue work on weed control, pest management and disease control as needed.

• Participate with National Onion Growers Association and other state university Allium research on common industry objectives.

GORAB Director Bob Ehn and UC Farm Advisor Tom Turini, liaison to the Research Board, have participated with the University of California in developing a long range strategic plan for the West Side Research and Extension Center in Five Points.

In the process they have looked at major objectives for the station as well as obstacles and action plans to move forward. The major objectives of water management, quality, storage and availability were the most significant concerns of the stakeholders involved in the session.

Some elements of the long term plan are being implemented now. Lab equipment to allow diagnostic work on plant disease and other pests has been installed at the center, and improvements are expected to continue.

Instead of sending plant samples to Davis or Monterey County, much of the work can now be done at the station. Ehn said it was gratifying that GORAB was included in the group that developed the long

range plant. When finalized, the plan will be available on the UC West Side REC web site.

Funds for rot research sought; proposals submitted

The GORAB research committee has been actively pursuing outside funding to support continued work on white rot. Its request was part of a submission made by Mike Havey, University of Wisconsin/USDA that included several work issues for onions and garlic.

The GORAB segment requested funding for the use of onion and garlic by-products as biostimulants for white rot, but that US Onion and Garlic project was not funded this year. Possibilities for resubmission as part of the 2015 Farm Bill are being evaluated.

Grant proposals for funding have been submitted to the California Department of Pesticide Regulation Pest Management Advisory program and the USDA Western Region IPM Center. Instrumental in preparing those proposals were Rob Wilson, UCCE Tulelake; Mike Davis, UC Davis; Tom Turini, UCCE Fresno; Jeremiah

Dung, Oregon State Madras Research Station, and Michael Quan, Food Science Department, Oregon State University.

GORAB aids MRL meeting

As a member of the CA Specialty Crops Council, GORAB helped plan the annual Maximum Residue Levels(MRL) Workshop in San Francisco this past June. It drew people from all over the U.S., Canada, Mexico and a number of Pacific Rim countries, many of which have developed their own positive lists for imported food crops with pesticide residue. The event was well attended, with 121 registered. Presentations from the session are available on the CASCC web site.

The California Department of Pesticide Regulation has notified all parties that the 2013 pesticide use report (PUR) data will indicate that the San Joaquin Valley emission inventory exceeds both the trigger level and the State Implementation Plan(SIP) goals for VOC emission.

This means that it is unlikely that pest control advisers can recommend, nor growers use, high VOC products containing abamectin, chlorpyrifos, gibberellins or oxyfluorfen in the San Joaquin Valley during the period between May 1 and October 31, 2015 and 2016. Affected crops are alfalfa, almonds, citrus, cotton, grapes, pistachios and walnuts.

The regulation will be in place for two years or until VOC levels are below the 18.1 SIP and 17.2 tons per day trigger after two years, causing regulations to revert to 2013 rules. DPR suggested, but did not specify in the order, that additional products may be added if an exceedance occurs. Bifenthrin (Capture, Bifen) and fenpyroximate (Fuji-Mite) are candidates to be added.

Although the regulation does not affect use on onions and garlic grown in the San Joaquin Valley, it does affect three of the four listed products which also have high use on onions and garlic. However, it will affect availability of these products in any formulation other than low VOC.

Corky expects to become a grandfather for the fifth time in December, with an assist from his son K. J. and daughter in law Denee. His daughter Whitney has made him a four-time grandpa, and expects to up the total to five in February.

The solid agricultural background he brings to Ruegger and Ruegger and to the GORAB board of directors includes several years of farming in the Salinas Valley and in Kern County.

• FONTELIS FUNGICIDE. DuPont Crop Protection has been granted a California supplemental label for use of Fontelis Fungicide for control of soil borne disease Rhizoctonia seedling blight (Rhizoctonia spp.) and white rot (Sclerotium cepivorum) when applied at plant, pre-plant incorporated, in-furrow, transplant drench or drip irrigation time. The previous label only allowed use as a foliar application. The expanded applications allows for white rot control at 16-24 fluid ounces per acre in a 4 to 6-inch band in furrow at planting. This provides an additional tool for white rot management.

• PROWL H2O (pendimethalin) Herbicide Section 24(c). Work continues with BASF to gain approval for a third party Section 24(c) label to allow Prowl H2O for kochia weed control in processed onions. It will call for application at the delayed emergence timing (after onion seed sprouting, but before emergence). Use is requested in Siskiyou, Shasta, Lassen and Modoc Counties. The Section 24(c) label was submitted to the CA Department of Pesticide Regulation (DPR) early this year, but has encountered difficulties. BASF and DPR have been unable to resolve wording in waiver and release of liability and indemnification language for the label. It is hoped this issue can be resolved before the 2015 planting season. Trials have also been initiated with Kurt Hembree, UCCE weed scientist in Fresno County to look at weed control and plant safety with a similar application timing for Valley onions.

• ABAMECTIN garlic clove drench. GORAB was granted a “A” priority for IR-4 work to register abamectin (Agri-Mek, Abba CS, Abacus) as a garlic clove drench following hot water treatment to gain bulb and stem nematode control. The registration of abamectin on bulb vegetables for thrips and other pest control provided an opportunity to pursue a clove drench treatment on garlic using the same tolerance.

In discussion IR-4 had with basic registrant, concerns were expressed for mixer, loader, applicator safety with a drench treatment, resulting in reluctance to approve the project. GORAB proposed a third party 24(c) registration for California only to be held by the Board. The proposal is under consideration.

• SYNGENTA’S NEW RUST MITE MATERIAL shows excellent garlic rust control in CA fields. The fungicide, Solatenol is under joint review in the US, Canada and Mexico , with registration due on major crops December 18, 2014. Bulb vegetables are being registered through an agreement with IR-4 (Interregional USDA Minor Crops Program) with registration anticipated in 2016. Ryan Bounds, Syngenta research biologist worked with the GORAB research committee to get this use entered in the IR-4 program, and provided an opportunity for CEO Bob Ehn to view plots this summer. Field results show this new fungicide to be significantly better than the standards azoxystrobin (Quadris) and tebuconazole (Folicur, Orius).

John Duffus, The Garlic Co.Dehy onions spice Wycuff crop menu

Dehydrated onions may be at the top of the list, one that also includes alfalfa, sugar beets, carrots, Bermuda grass for seed and hay and Sudan grass for hay – the crops Corky Wycuff is responsible for as farm manager for Ruegger and Ruegger in Westmorland.

Corky has been a GORAB board member since 2006. A 1972 graduate of Cal Poly with an animal science major, his first job was with the Templeton Livestock Market. After three years there he turned to other commodity and career interests, and hasn’t relied on his major since.

He has been with Ruegger and Ruegger for the past 15 years, and a proud resident of Westmorland and the Imperial Valley. He is serving his second term (sixth year) as a member of the Westmorland Union Elementary School District.

Desert off-roading in his jeep is a frequent and restful pastime. A more socially oriented hobby is

emergence and growth of onions.Research support by GORAB focused on the

evaluation of pre-emergence and post emergence herbicides applied at several rates and application timings on two different soil types. Results showed that DCPA (Dacthal) applied post-plant and pendimethalin (Prowl H2O) applied at or before the loop stage reduced kochia, lambsquarters and hairy nightshade density compared to untreated plots. An additive effect occurred when the two herbicides were applied in combination, especially for kochia control.

Wilson’s studies refute a long held belief that Dacthal becomes tied up in the fine textured, high organic matter Tulelake soils. His data show that Dacthal applied

after planting is effective and economical when used at affordable rates in combination with Prowl H2O. Prowl H2O applied at the loop stage worked in most situations, but under heavy kochia pressure,

Rob Wilson, Station Director Tulelake (IREC) discusses weed control at the IREC Field Day

IREC Research Station Manager Rob Wilson emphasized weed control for onions and garlic at the Tulelake station’s annual field day on August 13, part of a full day’s program attended by an enthusiastic group of Allium specialists, growers and researchers.

Wilson’s research, including studies sponsored by GORAB, has focused on control of early emergence weeds such as kochia, common lambsquarters, redroot pigweed and hairy nightshade. Kochia in particular slows the
