First Brown Marmorated Stink Bug found in Ada County

Brown Marmorated Stink Bug
Posted on: October 30, 2014 by Paul Castrovillo
On October 20, 2014 the first capture of a brown marmorated stink bug (Halyomorpha halys) in Ada County was confirmed. An alert homeowner in the Boise North End found the living insect in his garage and brought it to ISDA for verification of his identification. A follow-up inspection of the property failed to turn up any more specimens, which at this time would be attempting to locate suitable protected overwintering sites. In the spring, when stink bug activity would be expected to resume another inspection will be made and brown marmorated stink bug pheromone traps will be set up in the neighborhood to determine whether or not a population has established. Brown marmorated stink bug is an invasive pest from Asia. In the US it was first collected in Pennsylvania during the late 1990’s and since then has been detected in 41 states, with large infestations in the East and even some outbreak areas in Oregon, Washington and Utah. It feeds on a number of fruit and vegetable crops and can be a nuisance pest when congregating in human dwellings. In 2012 several specimens were transported from Maryland to Nampa, with reports of a few escaping, however no evidence of an established population has been uncovered in that area through subsequent inspections or trapping.

2014 Japanese Beetle Field Season Finishes
Announcements All Locations
Japanese Beetle
Posted on: October 6, 2014 by Paul Castrovillo
Traps all over the state came down last week signifying the end of Japanese Beetle (JB) monitoring in Idaho for the 2014 field season. In total 1,283 adult beetles were collected in the traps between June 19 and October 1. That is a 58% reduction compared to the 3,058 JB captured during 2013. This is attributed to the effect of targeted insecticide treatments that were part of the current JB eradication program in Boise. One area in the Warm Springs neighborhood where 1,930 beetles were trapped in 2013, and which was subsequently treated, produced only 92 adults this summer – down 95%. JB were not found in traps located anywhere else in the state.
Data is currently being analyzed and plans being made for monitoring/treatment of JB in 2015. This information, once finalized, will be available on the Idaho State Department of Agriculture website. With questions please contact Paul.Castrovillo@agri.idaho.gov or call 208-332-8627.

Only one potato psyllid was found this week, in Twin Falls County, at one of our “intense” monitoring fields. Very few fields remain as we are nearing the end of the season. None of the psyllids tested from last week was positive for liberibacter (Lso), the bacterium that causes zebra chip.

potato psyllids
Posted on: September 26, 2014 by Erik Wenninger
Most of our fields have now undergone vine kill and are no longer being monitored. The busy harvest season has delayed delivery to our lab of some cards from this week (including those from a few sites in western Idaho that have been trapping the most potato psyllids); those results will be posted as early as possible next week. Among the few remaining sites still being monitored, we did trap one psyllid in Cassia County (the first capture at that site this year) and a few psyllids at two different sites in Canyon County.
In addition, a psyllid that was collected from a Canyon County field on Sept 8 tested positive for liberibacter, the bacterium that causes zebra chip.

potato psyllids
Posted on: September 19, 2014 by Erik Wenninger
Potato psyllids continue to be trapped at relatively high rates in just a few fields in Western Idaho (Canyon, Owyhee, and Elmore counties). We also trapped one psyllid in a field in Jerome County this week. None of the psyllids tested from last week was positive for liberibacter (Lso), the bacterium that causes zebra chip. During this busy harvest season, we are still waiting for some cards to come into our lab, so those results will be posted as early as possible next week.
Many of the fields we are monitoring have undergone vine kill. For those fields that have yet to be vine killed, it is important to consider management options for psyllids and zebra chip in order to keep the crop protected until harvest—especially in western Idaho where psyllid numbers have been higher.

Posted on: September 12, 2014 by Erik Wenninger
A potato psyllid collected from a grower’s field in Owyhee County last week tested positive for liberibacter (Lso), the bacterium that causes zebra chip disease. This psyllid was collected on a sticky trap in the same field that trapped an Lso-positive psyllid two weeks before. During this week we trapped an additional eight psyllids (average of two per card) in that same field that will be tested for Lso. We also trapped psyllids in a few other sites in Canyon and Elmore Counties this week. Again, psyllid captures were higher this week in western Idaho than central and eastern Idaho; only one psyllid was found on a sticky trap in the Magic Valley this week (Twin Falls County).
Many of the fields we are monitoring have undergone vine kill. For those fields that have yet to be vine killed, it is important to consider management options for psyllids and zebra chip in order to keep the crop protected until harvest—especially in western Idaho where psyllid numbers have been higher.

Idaho psyllid monitoring update

potato psyllids
Posted on: September 5, 2014 by Erik Wenninger
Potato psyllid captures in our monitoring program were at similar levels to the previous two weeks (i.e., slightly higher than in previous weeks, though still relatively low compared to previous years). Again, most psyllids—nearly all this week—were found in the Treasure Valley (Canyon and Owyhee Counties) or Elmore County. In addition we captured one psyllid at a site in Twin Falls County. Psyllid numbers were the highest we’ve seen yet this year (1.25 or 1.75 on average per card). This is not surprising given the trend of increasing psyllid numbers toward the end of the season that we have observed during the last two years. It is important to consider management options for psyllids and zebra chip in order to keep the crop protected until harvest.

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.

Potato Late Blight Continues to Spread
Potato All Locations
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.
