Sugarbeets Magic Valley
sugarbeet root maggot
Posted on: May 25, 2010 by Jerry Neufeld
The degree day calculator (hosted by the Integrated Plant Protection Center at Oregon State University) for the sugarbeet root maggot fly shows that—depending on your location in the Magic Valley—we have accumulated about 237 degree days since March 1, 2010. Peak emergence of root maggot flies should occur around 350 accumulated degree days when the maximum high temperature exceeds 80 degrees F. In the Mini-Cassia area, this usually occurs around the 2nd of June. With recent temperatures being cooler than average, peak flight should occur slightly later (around the 5th of June in the Rupert area).
Monitoring flies adjacent to your sugar beet fields using orange sticky stake traps will provide even more useful information regarding the local population densities of flies. The Amalgamated Sugar Company monitors flies with sticky stake traps throughout the Mini-Cassia area and posts the counts on their website: http://www.srcoop.com/ The economic threshold for application of granular insecticides against root maggots is an accumulative total of 40-50 sugarbeet root maggot flies per sticky stake trap (the threshold varies depending on your contract price per ton). In the Mini-Cassia area, which historically has had high root maggot pressure, growers should consider an insecticide application 10 days before exceeding threshold captures on sticky stakes. Otherwise, insecticide applications should be made within 10 days before or after reaching the threshold (the closer to the threshold date, the better). Activation of granular insecticides should be accomplished by irrigation as soon after application as possible. See University of Idaho publication CIS 999, IPM Guide to Sugar Beet Root Maggot: http://www.uiweb.uidaho.edu/sugarbeet/insc/sbmaggot.htm
You can monitor degree day accumulation for sugarbeet root maggots as follows:
1) Log onto: http://uspest.org/cgi-bin/ddmodel.pl?spp=srm
2) Select “Sugarbeet Root Maggot Bechinski et al. 1990” degree day model from the “Select degree day model….” drop down box at the top of the form
3) In the “Select location” box, select a location in the drop down box best describing your location (e.g. “RUPERT id agmet” in the “Washington, Idaho” box if you want information for a field near Rupert). Make sure to select “None” at the top of the lists in the other two location boxes.
4) Leave the “Or upload your own…” box blank
5) In the “Forecast:” area, enter your zip code or your city, state in the “NWS zipcode/city, state” box, or the location nearest your field from the “or weather.com site” drop down box to the right). This selection forecasts 7 days forward based on the local weather forecast (beyond 7 days the forecast is based on the historical average). The predicted date of peak fly flight will vary depending on the forecast location selected, so pick the one closest to your location. Select “none” to have the forecast based only on the historical average.
6) Select the location nearest your field in the “Select historical average forecast location” area. Your selection here should match, as close as possible, your selection in the “Select location” area above: there may not be an exact match. As above, select “none” in the other two boxes.
7) Make sure the “Table” and “graph” boxes are checked (and the “precipitation” if you want rainfall information) and click the “Calc” button. A table with the current degree day accumulations matching your selection should appear. There should also be a graph near the bottom showing the current year accumulation compared to the historical average for your selections.

bacterial blight in barley
Small Grains Magic Valley
bacterial blight
Posted on: May 25, 2010 by Jerry Neufeld
UI Extension Plant Pathologist Oliver Neher is reporting that bacterial blight has been found in barley in the Paul area (Magic Valley). Bacterial blight is favored by several factors including high moisture (rain or irrigation), cool temperatures, and mechanical damage such as equipment or wind which transports sediment. There are no products labeled to treat bacterial diseases. About the only practical treatment a grower can employ is to reduce moisture (irrigation) if bacterial blight is found in your fields.

sugarbeet root maggot
Posted on: May 18, 2010 by Jerry Neufeld
According to a representative from Amalgamated Sugar Company, growing degree day models indicate that adult sugarbeet root maggot flies will begin their spring emergence and begin flying in the very near future. Adult flies will lay eggs near sugarbeet plants. After the larvae hatch they will begin feeding on the young sugarbeets. AMSCO representatives have not seen any adult flies yet, but warn they will be flying any day now. Look for these pests to appear in the western end of the Treasure Valley first. If you haven’t applied a treatment for sugarbeet root maggot, now is the time to do so. Consult your crop advisor or field representative from AMSCO for treatment options.
lygus in alfalfa seed
Alfalfa Seed Treasure Valley - Idaho
lygus bug
Posted on: May 18, 2010 by Jerry Neufeld
The Lygus degree day calculator hosted by Integrated Plant Protection Center at Oregon State University (http://pnwpest.org/cgi-bin/ddmodel.pl?spp=lyg) shows that, depending on your location in the Treasure Valley, we have accumulated about 227 degree days since January 1, 2010. Peak emergence of lygus bug 1st and 2nd instar nymphs should occur right around 272 accumulated degree days: this usually occurs around mid-May, and is the time monitoring for lygus bugs in alfalfa seed fields should begin. Right now that is predicted to occur on about May 27 in the Caldwell area.
When using most insecticides, fields should be treated when numbers of lygus bugs reach 4-5 lygus bug nymphs per 180 degree sweep. Growers using Rimon, Assail, or Beleaf, as stand-alone sprays should treat before 4th instar nymphs are detected. You can monitor degree day accumulation using the link provided above as follows:
1) Select “ lygus bug [alfalfa seed]Ben Simko 2000” degree day model from the “Select degree day model….” drop down box at the top of the form
2) In the “Select location” box, select a location in the drop down box best describing your location (e.g. “parma id agrimet” in the “Washington, Idaho” box if you want information for a field near Parma). Make sure to select “None” at the top of the lists in the other two location boxes.
3) Leave the “Or upload your own…” box blank
4) In the “Forecast:” area, enter the your zip code or your city, state in the “NWS zipcode/city, state” box, or the location nearest your field from the “or weather.com site” drop down box to the right). This selection forecasts 7 days forward based on the local weather forecast (beyond 7 days the forecast is based on the historical average). The predicted date of peak 1st and 2nd instar will vary depending on the forecast location selected, so pick the one closest to your location. Select “none” to have the forecast based only on the historical average.
5) Select the location nearest your field in the “Select historical average forecast location” area. Your selection here should match, as close as possible, your selection in the “Select location” area above: there may not be an exact match. As above, select “none” in the other two boxes.
6) Make sure the “Table” and “graph” boxes are checked (and the “precipitation” if you want rainfall information) and click the “Calc” button.

frost injury in winter barley
Small Grains Treasure Valley - Idaho
frost
Posted on: May 18, 2010 by Jerry Neufeld
Cereals Specialist Dr. Brad Brown from the UI Parma Research and Extension Center is reporting that yesterday some winter barley was brought in with all the symptoms of frost injury. Awns were twisted and the flag leaf was bound and twisted and was hindering head emergence. Some heads at the top had spikelets burned which were entirely white with no green color, and some spikelets below them were green but no discernible developing seed which may have aborted from the frost injury. The symptoms are similar to and commonly mistaken for 2,4-D injury, but differ in that frost injury shows parts of the head that are sterile. The publication “Spring Freeze Injury to Idaho Cereals”, Idaho Cooperative Extension Bulletin 724 describes the injury from frost in more detail. Click on the pdf below to read this publication.

Fieldmen from Landview Fertilizer are reporting that cutworms have been found in several established mint fields south of Nampa. According to U of Idaho CIS 773, Insect Control Recommendations for Mint Production in Idaho, “ The first sign of cutworm damage is when the mint is not growing, or only part of a mint field is growing in the spring. If you examine mint plants closely and find the underground rhizomes are cut off or seriously damaged, cutworms may be nearby in loose soil or plant debris.” Click on the link below to read CIS 773.

GAP Audit
Posted on: April 2, 2010 by Nora Olsen
The University of Idaho has updated the previously available Potato GAP Audit Organizational Manual. The UI manual is designed to simplify the collection of information necessary to pass the USDA GAP Audit and is now available for download at the UI Kimberly R&E Potato Storage website: http://www.kimberly.uidaho.edu/potatoes/gap.htm.
In November of 2009 the USDA replaced the May 11, 2007 version of their Good Agricultural Practices (GAP) & Good Handling Practices (GHP) Audit Verification Checklist. The new version has three major changes: 1) new identification of records, policy or documentation requirements, 2) new numbering, wording or point values for previously asked questions, and 3) the addition of new questions and traceability questions were added to each section. The updated UI GAP Audit Organizational Manual incorporated these changes into the newest version and this manual will be useful in preparing for the 2010 GAP Audit.
