potato psyllids
Posted on: August 29, 2014 by Erik Wenninger
Potato psyllid captures in our monitoring program slightly increased last week and remained at similar levels this week. Most psyllids during the last two weeks were found in the Treasure Valley (Canyon, Payette, Owyhee Counties) or Elmore County.
In addition, one of the psyllids collected in Owyhee County last week tested positive for Lso (liberibacter; the bacterium that causes zebra chip). This is only the second psyllid that has tested positive so far in the commercial fields we have been monitoring.
We typically observe an increase in psyllid captures at the end of the growing season; however, it is likely that the heavy rains we have experienced recently have affected psyllid numbers. It is important to consider management options for psyllids and zebra chip in order to keep the crop protected until harvest.

Late blight
Posted on: August 22, 2014 by Phil Nolte
Two fields with late blight in Fremont County were confirmed today. There are multiple late blight fields in Madison, Bingham, Bonneville and Power Counties. The current recommendation is if anyone in the affected counties has not applied a protectant fungicide to their potato fields do so immediately. Until vine kill the University of Idaho recommends that potato fields be kept on a 7 day spray schedule. Rain is predicted to continue in all of the current late blight infected counties and rain is very efficient at moving late blight spore around. .
It is essential to protect green, growing vines with fungicide applications. Spores of the late blight pathogen are washed from the foliage into the soil causing tubers to become infected. Sometimes tuber infection can occur with very little foliar late blight. Protecting the foliage of Ranger Russet fields is particularly important because the vines remain green longer and the tubers are highly susceptible to tuber infection.
If late blight is present in your field, we recommend a post-harvest application of a phosphorous acid (phosphite) product going into storage at the rate of 12.8 fl oz/ton applied at a volume of 0.5 gal/ton of potatoes. Ensure you are not over-applying which may add too much water to the harvested potatoes. Potatoes should NOT be shiny wet, but rather barely damp. Apply at a point in the handling process where potatoes are rotating or dropping to ensure the best coverage. These post-harvest products will not cure infected tubers but will protect healthy tubers form becoming infected in storage.
Please bring any suspicious samples in to the University of Idaho or Miller Research for positive identification.

Potato Psyllids
Posted on: August 22, 2014 by Erik Wenninger
Potato psyllid captures in our monitoring program slightly increased this week in terms of numbers (but remain relatively low compared to previous monitoring years) and locations (Magic and Treasure Valleys). Psyllids were found on sticky traps in commercial potato fields in Owyhee, Canyon, Ada, Elmore, and Twin Falls Counties.
None of the psyllids found so far in commercial fields (except for one on Canyon County during mid-July) has tested positive for Lso (liberibacter; the bacterium that causes zebra chip).

Late blight
Posted on: August 20, 2014 by Phil Nolte
An additional potato field in Madison County has been confirmed with late blight.
Previously, late blight had been confirmed in Power County, Bonneville County, and Bingham County. The current recommendation from the University of Idaho is for everyone to apply a protectant fungicide immediately. The rain showers we have been experiencing lately provide perfect conditions for late blight to spread. Please remember that late blight also has the ability to infect tubers growing in the ground as spores move from the plants into the soil. Stay on a 7 day spray schedule and continue to scout fields carefully. Please bring any suspicious samples in to the University of Idaho or Miller Research for positive identification.
Sprout damage in grain

Rain at Harvest
Posted on: August 19, 2014 by Juliet Marshall
Guidance to Idaho malting barley producers experiencing higher than acceptable sprout damage in their 2014 malting barley crop
Growers are urged to be patient and not panic as they try to complete their 2014 growing season. We recommend producers follow these steps:
1. Follow best management harvesting practices, particularly avoid harvesting lodged barley. Beware that injured by sprout barley is more fragile and more susceptible to skinned and broken kernels.
2. Quickly harvest the remaining grain to prevent growth of molds. Sooty molds will increase off flavors in malt and reduce suitability for feed.
3. Store your barley with good aeration. Grain is stored best if it is cool, dry and clean. The recommended maximum moisture content for storage of clean sound barley during warm summer temperatures is 12%. Barley can be stored at slightly higher moisture content if it is kept cool.
4. Take a good bin sample as your put your barley into storage and work with your malting barley company to have the barley tested for injured by sprout.
5. Be patient and give your malting company time to determine what portion of your crop can be used as malting.
6. Try to avoid dumping your barley as feed at harvest as the commercial feed barley prices have been dropping rapidly.
Your malting companies are going to extraordinary lengths to test Idaho malting barley that has been injured by sprout and to determine how much can be used for malting. They are researching and micro malting samples to determine the highest limit of sprout damage they can take without compromising the malting and brewing process.
It is important to understand why sprout damage poses a risk in the brewing process. Pre-harvest sprouting (PHS) or pre-germination impacts the ability of barley to germinate. Problems can range from a slow loss of germinative energy or capacity over time in storage to the complete loss of germination at the time of harvest. Barley used for malting must exhibit vigorous and uniform germination. In malting, pre-harvest sprouted barley can lead to poorly modified malt that is unsuitable for the production of beer. Low extract yields, poor beer stability and off-flavors are just a few of the problems that can result from PHS damaged barley.
Barley kernels remain resistant to sprouting prior to physiological maturity. Some varieties maintain a level of resistance (dormancy) for a significant time after harvest. Certain conditions like heavy rainfall at maturity can reduce this level of resistance to germination.
The bottom line is that barley with sprout damage, even if it germinates well after harvest, can lose germination rapidly in storage. There are no tests that can predict when a sudden drop in germination will occur. Even if a relatively high degree of germination remains in a lot of barley, the germination may be uneven with some kernels germinating much slower than others in that lot resulting in a malt that does not meet brewers minimum specifications for beer production.

Late blight
Posted on: August 15, 2014 by Nora Olsen
Late blight has been positively confirmed in Idaho. Today one field has been confirmed in Power County and one field in Bonneville County. There are a total of three confirmed late blight fields in Bingham County. The current recommendation from the University of Idaho is for everyone to apply a protectant fungicide immediately. The rain showers we have been experiencing lately provide perfect conditions for late blight to spread. Please remember that late blight also has the ability to infect tubers growing in the ground as spores move from the plants into the soil. A quick reminder, tomatoes in home gardens are also susceptible to late blight infections. Stay on a 7 day spray schedule and continue to scout fields carefully. Please bring any suspicious samples in to the University of Idaho for positive identification.

Potato psyllid captures in our monitoring program were similar to recent weeks in terms of numbers (relatively low) and locations (Magic and Treasure Valleys). Psyllids were found on sticky traps in commercial potato fields in Canyon, Ada, Jerome, and Twin Falls Counties. This represents the first potato psyllid captured in Ada County in our monitoring network this year. We also captured four psyllids in vacuum samples at bittersweet nightshade sites in Twin Falls County.
None of the psyllids found so far in commercial fields (except for one on Canyon County during mid-July) has tested positive for Lso (liberibacter; the bacterium that causes zebra chip).

Farming with Pollinators and Beneficial Insects Field Day
The Northwest Center for Alternatives to Pesticides invites farmers interested in increasing pollinator and beneficial insect habitat on their farms to attend a Wednesday, September 3 field day.
Clay and Josie Erskine of Peaceful Belly Farm, located in the Dry Creek Valley north of Boise, will host the field day from 9 am – 12:30 pm.
The Erskines will show how they have incorporated pollinator and beneficial insect habitat on their farm by planting willows in a riparian area, native bunch grasses and clover on farm roads, perennials into a hedgerow, and the management of successive plantings of brassicas to flowering.
Jessa Kay Cruz, senior pollinator conservation specialist with the Xerces Society, will present her work with farmers to establish habitat for pollinators and beneficial insects in irrigated cropping systems. She will cover how to assess existing habitat and identify areas to improve, year-round beneficial insect and pollinator habitat requirements, and certified organic methods of site prep for establishing habitat.
Copies of the Xerces Society’s new book Farming with Native Beneficial Insects: Ecological Pest Control Solutions will be available to review or purchase.
The field day will conclude with a farm lunch and discussion of funding opportunities, including a new microloan program through Farm Service Agency and conservation funding through Natural Resources Conservation Service.
The cost is $15 and pre-registration is required. Register online at www.pesticide.org or contact Jen Miller (jmiller@pesticide.org or 208-850-6504) by August 27. Details at www.pesticide.org.
This tour is made possible by support from USDA Natural Resources Conservation Service Conservation Innovation Grant, USDA Risk Management Agency Education partnership funding, and University of Idaho Canyon County. This is an equal opportunity event.

Relatively few potato psyllids were captured in our monitoring program this week overall, and, similar to recent weeks, most psyllids captured were found in the Magic Valley. Of these, most were found in fields in Twin Falls County, though we did find two psyllids in a field in Minidoka County this week (the first finds this year in this county). In addition, we found a psyllid in Canyon County and, for the first time this year, in Payette County.

glyphosate-resistant kochia
Sugarbeets Treasure Valley
kochia
Posted on: August 4, 2014 by Jerry Neufeld
This is an update to the alert that was posted on June 11, 2014 regarding the suspected glyphosate-resistant kochia plants in Western Idaho and Eastern Oregon sugar beet fields. It has now been confirmed that the plants that escaped control in at least two fields in Eastern Oregon were indeed resistant to glyphosate. Tests done by the weed laboratory staff at Colorado State University in Fort Collins, CO confirmed the resistance. Kochia weed seeds will be collected from different fields at the end of the season in order to determine the distribution of glyphosate-resistant kochia in the region.
In the meantime, we would encourage growers to physically remove kochia plants that escaped control in sugar beet fields (if at all possible) in order to minimize the buildup of glyphosate-resistant seeds in the soil. Also, please report any suspicious kochia escapes to your local crop consultant, crop advisor, extension educators, Joel Felix (OSU weed scientist), or Don Morishita (UI weed scientist).

Posted on: August 1, 2014 by Erik Wenninger
Few potato psyllids were captured in our monitoring program this week overall, and psyllids were found this week only in Twin Falls County (however, results from several Treasure Valley sites have not yet been returned to us). One of these was a nymph, found in a vacuum sample from a commercial field; this is the first nymph found this summer in our monitoring program. In addition to the few psyllids found in our network of commercial potato fields, we also found four psyllids on yellow sticky cards near bittersweet nightshade sites in Twin Falls County, and several potato psyllids on sticky cards and in vacuum samples taken from insecticide trials at the Kimberly R&E Center. Nearly all of the Idaho Potato Team has been at the Potato Association of America meetings in Spokane this week. We regret the delay this has caused in testing psyllids for Lso (liberibacter; the bacterium that causes zebra chip). Samples are currently being processed and we expect to post results to the spreadsheets below by early next week.

Two-spotted spider mite
Posted on: July 31, 2014 by Bill Buhrig
Two-spotted spider mites are being found in sugar beet fields in the Treasure Valley. Implementing proper scouting procedures and working with your crop consultant should be done to determine if action is necessary. For more information on the two-spotted spider mite, consult the PNW Insect Handbook at the link below.
On a related note, there has been a Section 18 granted for specific counties in Idaho and Oregon for the use of the miticide Onager in sugar beets. This is a very specific label that includes expiration dates in the coming weeks. For the eligible counties in Oregon, this label expires August 14, 2014. For eligible counties Idaho, this label expires August 31, 2014.
As is the case with all pesticides, please read and follow the label carefully!

earworm
Posted on: July 29, 2014 by Jerry Neufeld
I am collaborating with Charter Seed Co. and Crookham Seed Co. on a project to trap corn earworm moths. We set out 7 traps in corn fields at various locations from near Melba to near Wilder. I am checking the traps every few days and posting the moth counts to this website. Below are the moth counts from this week. Once again, I did not find any adult corn earworm moths in the traps.
There are a couple of models that can be used to predict the emergence of the summer generation of corn earworm moths. This is the generation that lays eggs in corn that is silking at the time of their emergence.
One model uses January 1 as a biofix, 55 and 95 as the temperature parameters and predicts the summer moths will appear after 1300 growing degree days (GDD) and begin laying eggs in fresh corn silk. This model also estimates the eggs will hatch and larvae will begin feeding on corn ears 73 GDD later. According to this model, we reached 1300 GDD in the Parma area on 7/21 and 1300 GDD in the Caldwell area on 7/25, yet I have not found any adult moths. We will reach 1300 GDD in the Nampa area today.
The second model simply uses 8/1 as the default date; the date the summer moths will emerge and begin laying eggs in fresh corn silk.
Since I have not found any adult moths yet there could be several things going on. 1) The traps and lures are not working. I used these traps with CEW pheromones lures a few years ago and they worked just fine. 2) There aren’t any corn earworm moths this year. It could happen, but this is rather unlikely. 3) The model using January 1 as a biofix isn’t quite right for our area. My suspicion is that the model using January 1 as a biofix is not quite accurate for our area and we will soon see the summer generation of moths appear. I have talked to some industry people and like me, they have not yet seen the summer generation of CEW moths. Stay tuned, I will check the traps next week and let you know what I find out.

Posted on: July 25, 2014 by Erik Wenninger
Psyllid numbers captured in our monitoring program this week were similar to the numbers captured last week; however, we found for the first time this year potato psyllids on sticky traps in potato fields in the following counties: Owyhee, Gooding, Cassia, and Power. As reported earlier this week, one potato psyllid collected last week (Canyon County) tested positive for liberibacter (Lso), the bacterium that causes zebra chip disease. No other psyllids tested so far this year have been positive.
Potato psyllids are beginning to appear in more counties, including those that are further east in our monitoring network. Local monitoring and management programs should be in place in these areas.
