Armyworm damage in eastern Idaho wheat fields
Small Grains Eastern Idaho
armyworm
Posted on: October 6, 2020 by Jerry Neufeld
The following information is provided by Dr. Arash Rashed, Associate Professor, Department of Entomology, Plant Pathology and Nematology at the University of Idaho.
There have been reports of fall armyworm damage in some wheat fields between American Falls and Firth in eastern Idaho. Please inspect your fields as managing this pest is more effective during the early stages of development. Fall Armyworms are active during dark, so field inspections need to be done with a flashlight after sunset. They have a wide host range but prefer grasses; at this time of the year, wheat, barley, alfalfa, volunteers, and pasture are examples of crops that can host fall armyworms. They feed on foliar tissue and can consume young seedlings to the ground. During the day they hide in plant litter and/or just below the soil surface. There are no set thresholds and management recommendations depend on the stages of plant and larval development and the extent of the damage. More than 2-3 larger larvae (> 1/2in) per square foot may require control. Scout as many spots as possible within a field. Damage by fall armyworm is usually patchy and spot insecticide treatment is a possibility, where needed. Larvae cannot survive freezing temperatures and are also susceptible to diseases caused by entomopathogens at high densities.
For other closely related species and damage, you can visit pages 493-499 of the publication in the first link below:
You can also learn more about this pest from the PNW Insect Management Handbook in the second link below:

Grasshoppers
Small Grains Eastern Idaho
Grasshoppers
Posted on: August 27, 2020 by Jerry Neufeld
The following information is provided by University of Idaho Extension Specialists, Drs. Arash Rashed and Juliet Marshall.
Recent reports from Montana are indicating the presence of grasshoppers in large numbers, an observation which has raised concern for winter wheat planting across the region. Although grasshopper populations are expected to decline in late summer and fall, young winter wheat and barley fields may be at risk if large numbers of grasshoppers are present at planting and crop emergence. The presence of 11-20 grasshoppers in one square yard (9 square feet) of natural border vegetation around a recently planted wheat field would be alarming and could result in significant damage upon seedling emergence.
Insecticide applications in form of seed treatments, foliar applications, and/or baits are primary approaches when large number of grasshoppers are present. However, delayed fall planting is also recommended to be integrated into the management protocol as it would minimize the window of fall crop exposure to grasshoppers. Monitor fields and surrounding vegetation. If large grasshopper populations are present, contact Idaho State Department of Agriculture (ISDA Mormon Cricket and Grasshopper Control Program at the link below. ISDA’s Mormon Cricket and Grasshopper Control Program provides pest management recommendations and assistance to producers and ranchers across Idaho.

Seed Piece Decay Due to Soft Rot
Potato Eastern Idaho
Pectobacterium spp.
Posted on: June 5, 2017 by Kasia Kinzer and Phillip Wharton
In the past few weeks we received three separate unrelated calls regarding poorly performing and rotting potato seed pieces in fields in eastern Idaho. Based on field visits and samples that were brought in to the extension seed potato lab in Idaho Falls, the predominant problem appears to be soft rot. The common theme of these samples were that they were from fields which were waterlogged, and most of the seed pieces that we looked at had enlarged lenticels.
Soft rot is caused by bacteria that produce pectolytic enzymes that break down pectin (polysaccharides found in plant cell walls). The soft rot pathogens can also grow and reproduce in environments where oxygen levels are low, a situation that can occur in wet soil. Soft rot pathogens need wounds or enlarged lenticels to gain entry into the potato tuber. They are not able to breach an intact, healthy, uncompromised tuber, which is why soft rot often appears after seed piece decay caused by Fusarium species. More rarely in Idaho, soft rot may follow seed piece decay caused by Pythium leak or late blight. Another important note about soft rot pathogens is that, although they can be tuber-borne, they can also be found in soil and water in the environment.
The seed pieces had been treated with a fungicide dust treatment immediately after cutting, and consequently, low levels to no Fusarium dry rot were observed on the samples. In all three cases, the fields were planted within 48 hours of seed being cut, which means the wounds from cutting were not fully healed. Our spring was particularly wet in most locations across Idaho. The combination of the enlarged lenticels, likely due to wet field conditions, and unhealed wounds on seed pieces planted in wet soils seems to have created the perfect environment for soft rot to thrive.
Unfortunately, there are few measures that can be taken to control soft rot after planting apart from drying out the soil to the extent possible, such as by shutting off or reducing irrigation. In some cases, if soft rot has affected over 50% of the field, and there is sufficient seed available, the grower may want to consider plowing up the field waiting for it to dry out sufficiently and the soil temperature to rise above 55F and then re-planting.

Potato Diseases Update
Potato Eastern Idaho
late blight, early blight, white mold, bacterial stem rot
Posted on: August 8, 2015 by Phillip Wharton
In the Treasure Valley area Dr. Mike Thornton reports that they are primarily seeing white mold, bacterial stem rot and early blight. The crop is beginning to senescence in some fields, and growers should be carefully monitoring soil moisture to make sure they match water applications to crop use.
In the rest of southern and south eastern Idaho conditions remain favorable for late blight. With the current frequent rain showers and thunderstorms moving through the area and cooler night time temperatures growers should be very vigilant for late blight. In the past two weeks, Dr. Jeff Miller has reported that most of the late blight out breaks have been spread by the thunderstorms moving through the area. This is evident by the uniform levels of disease spread throughout infected fields instead of in isolated infection points or at the edge of fields spreading inwards.
In the past week, the University of Idaho has confirmed 4 more positive infections in Power county and two more in Bingham county but none in Minidoka county. To date, the late bight out breaks appear to be limited to these three counties. All isolates from these outbreaks have been identified as the US 23 genotype and mefenoxam (Ridomil) sensitive.
As we move towards harvest, growers affected by late blight need to be aggressive in managing the disease at the end of the season and going into storage. Growers should be aware that in addition to attacking foliage, late blight can infect tubers at any stage of development before and after harvest and in storage, with symptoms and rot usually only showing up in storage. Late blight infection of tubers is characterized by irregularly shaped, slightly depressed brown to purplish areas on the skin. These symptoms may be less obvious on russet and red-skinned cultivars. A tan to reddish-brown, dry, granular rot is found under the skin in the discolored area, extending into the tuber usually less than half an inch. For more information and photos of late blight tuber symptoms see the attached link (http://bit.ly/1KWFt6a).
Late in the season it is advisable to avoid excessive irrigation as tubers become infected with late blight when spores wash down through the soil from infected leaves. Vines should also be killed at least two weeks before harvest, especially in blight infected fields. This interval minimizes the chance of tubers getting contaminated with late blight inoculum during harvest, and allows previously infected tubers to decompose in the field. If blight is present in the field or in the vicinity of the field at harvest, it may also be beneficial to spray foliage after vine killing with labeled fungicides to kill living late blight spores on the foliage.
For more detailed information on a late season checklist for managing late blight and fungicide fungicide recommendations see the attached link (http://bit.ly/1Kb3ELg).

Weekly Potato Disease Update
Potato Eastern Idaho
Late blight
Posted on: July 17, 2015 by Phillip Wharton
Potato diseases are starting to pick up across the state with the recent wet weather. Dr. Mike Thornton reports that in the Treasure Valley area, there were locally heavy rains associated with thunderstorms much of the past week with some hail damage in a few isolated areas. Cooler temperatures, when combined with the rain are favorable for diseases such as late blight, white mold and aerial stem rot (with hail damage). As such field men should be vigilant and fields should be scouted on a regular basis and growers are urged to apply protectant fungicides.
In the Magic valley early blight and white mold is on the increase due to recent rain showers. Again, due to the weather growers should be vigilant for signs of late blight.
In south eastern Idaho there are currently three confirmed fields in Bingham Co. with late blight. Genotyping of isolates have identified the strain as US 23. It is imperative that field men and growers bring in any suspected late blight samples to the university offices at Idaho Falls or Aberdeen for confirmation and so that we can monitor the late blight strains causing the epidemic. A knowledge of the strains involved in the outbreak will allow us to make better fungicide recommendations to growers. All sample origin information will be kept confidential with only the county of origin being reported.
Since the strains from the current outbreak in Bingham county are US 23, we are dealing with a mefenoxam sensitive strain of late blight. The most effect product for the control of mefenoxam sensitive late blight strains is Ridomil Gold Bravo. Ridomil has been shown to have curative properties and may halt a late blight epidemic if it is applied early enough in the outbreak (less than 1% field infection). Do not use Ridomil if you don't know what strain you have in your crop, as most other strains of late blight are resistant to Ridomil.
In fields where only a few random late blight lesions have been found evenly distributed throughout field (0 - 1% foliar infection), an application of Ridomil Gold Bravo should be made followed by a systemic fungicide such as Revus, Forum, Curzate 60DF, Ranman, Tanos, Gavel or Previcur Flex 5 - 7 days after the first application. The field should then be monitored closely until the end of the season and protectant fungicide applications (EBDC or Chlorothalonil products) made every 7 days until harvest. A late season application of Gavel has been shown to provide additional protection from tuber blight.
In infected fields with one or more (up to 5) loci spreading from the edge of the field or from several centers within the field (1% overall field infection but locally heavily infected plants 5 - 10%), infected areas should be destroyed with Reglone or a similar vine killing herbicide. Destruction of infected areas within the crop with late blight should follow the rules that 30 rows either side of the newest lesions at the border of the late blight locus and 100 feet along the row (either side) are killed with Reglone or with Gramoxone. Although harsh, research has shown that the latent period between infection and symptom development is about seven days and although not visible plants within this area are already infected. An application of Ridomil Gold Bravo should then be applied as above and followed by an alternative fungicide 5 days later. Protectant fungicide applications should then be made every 7 days until harvest.

Stripe Rust in Moreland Winter Wheat, Ririe
Small Grains Eastern Idaho
Posted on: July 23, 2008 by Juliet Windes
While small amounts stripe rust had previously only been confirmed in the Treasure Valley, yesterday I found it in Moreland hard red winter wheat in Ririe, ID. It was a significant infection, occurring on about 30-40% of the total leaf surface. The crop was in late milk to early dough, and it was too late to spray fungicides. In addition to significant stripe rust, there was about 30% white heads forming from foot rot fungi, probably take-all. Black chaff was also prevalent.
Addtional surveys will be conducted to see if the fungi have moved beyond the winter wheat fields into adjacent susceptible spring wheat. At this time, I consider this to be an isolated incident. Early season conditions were extremely conducive to the development of the disease, but there was no reported stripe rust. Spread of the current infection from this focus should be limited due to hot, dry weather conditions.
Information on control and effective fungicide treatments is availbale on our cereals website: http://www.ag.uidaho.edu/scseidaho/ then click on "Publications" for Plant Disease Management Reports, "Cereal Diseases" and / or "Routine Fungicde Yield and Economic Data".

Early blight forecast
Potato Eastern Idaho

The P-Day threshold for early blight has been reached in the three locations in eastern Idaho where weather data are being collected (Aberdeen, Fort Hall, and Rexburg). The threshold was reached on July 3 for Aberdeen and Fort Hall and July 5 for Rexburg. These predictions are based on early crop emergence dates. Potatoes should be treated for early blight at this time.
Stripe Rust in Wheat - Ririe, ID
Small Grains Eastern Idaho
Posted on: June 9, 2006 by Juliet Windes
A 5-acre field of Moreland hard red winter wheat in Ririe, ID, has stripe rust. This site is about 100 miles north-northeast of the last confirmed location. Please scout susceptible varieties often! The ten-day forecast predicts stormy, cooler weather that will be conducive to stripe rust spread and infection. Right now, spring wheat will be especially vulnerable. You can report new locations and varieties affected by calling Juliet Windes at 208-529-8376 or emailing jwindes@uidaho.edu. This is only to allow us to track the spread and infection of varieties and to alert growers in affected areas for the potential need to apply fungicides.

Stripe rust was found in two fields at the Aberdeen Research and Extension Center, both incidents were on Deloris hard red winter wheat. Small pustules were found on tips of flag leaves on two plants within the one field. While not (yet) extensive, this indicates inoculum is present in the area, and known susceptible varieties should be scouted regularly.

Posted on: May 30, 2006 by Juliet Windes
This is a follow up to Friday's report of stripe rust in irrigated Moreland HRW in Weston, ID. The grower reports stripe rust now in dryland Utah 100 HRW. Last Thursday, I saw chlorotic areas in Utah 100, but no active pustules. The infection was about a week behind that in the irrigated fields. Conditions over the holiday weekend were conducive to stripe rust spread and infection. PLEASE scout susceptible varieties and report occurences of stripe rust to your local county extension personnel.

Stripe rust was first seen in the Weston area on Monday, the 22nd of May. It was confirmed today, May 25th, and samples were taken in irrigated Moreland, hard red winter wheat. No pustules were visible on dryland wheat (Utah 100). Although current levels were at about 5-10% leaf area affected, most of the plants had stippling and chlorotic areas indicating a severe infection was still latent.

Stripe rust of wheat has been found in Power County south of American Falls. Regional conditions continue to be excellent for disease development, with cool wet temperatures favoring disease infection and spread. Fields of Deloris hard red winter wheat south of American Falls are severely affected (up to 80% incidence in some fields), but both spring wheat and winter wheat fields are beginning to show symptoms. Currently, Brundage soft white winter wheat had a minimal amount of visible pustules (about 1%), and no disease was yet found in Weston. Both Brundage and Weston are usually stripe rust susceptible varieties. The hard red spring cultivar Sunstar King was showing a few pustules in large areas where chlorotic plants were visible, similar to a nitrogen deficient crop. Scout such yellowing areas aggressively for signs of pustule development. More information and pictures will be available on the Cereals Agronomy website at http://www.ag.uidaho.edu/scseidaho. Please ! report infections of additional varieties by emailing Juliet Windes at jwindes@uidaho.edu, or by calling 208-529-8376, ext 13 and leaving a message. We need to monitor the area closely to determine if changes in the stripe rust pathogen have left previously resistant varieties susceptible. Current reactions in the Palouse region indicate that the same races of stripe rust are present that were there last year.

Late blight
Potato Eastern Idaho
Posted on: August 27, 2004 by Jeff Miller
Late blight has been confirmed near Blackfoot and east of Rexburg. Recent rains have made conditions ideal for disease spread. Intensive fungicide programs are needed up to vine kill. When vines are killed, make sure the vines die as quickly as possible. If you are using a slow vine kill method, then a fungicide application at vine kill is recommended.

Late blight
Potato Eastern Idaho
Posted on: August 20, 2004 by Jeff Miller
More fields have been identified with late blight, but they are all close to the original 5 identified focal points (3 in western Bingham county, 1 each in Cassia and Minidoka). Scouts in Bingham county have not found any late blight in the eastern portion of the county.
Recent thunderstorms have significantly increased the risk of late blight spreading to unprotected fields. Growers need to apply fungicides immediately after thundershowers to maintain adequate protection. As fields begin to die, fungicide application intervals can be stretched, but growers need to scout fields to be sure the pathogen does not come in at the end of the season.
If blight is found in a senescing field, the vines in the affected area should be killed. Anything that reduces the time of exposure of tubers to infected vines aboveground will reduce the risk of tuber blight in storage.
Potato Blight
Potato Eastern Idaho
Posted on: July 27, 2004 by Jeff Miller
Late blight has been found in Bingham county. So far, only one outbreak has been confirmed. However, the thundershowers that came across eastern Idaho Monday had the potential to spread the spores widely across the eastern portion of the state.
Most late blight fungicides are like sunscreen. They offer good protection wherever you get coverage and the fungicides get worn off over time. If you havent applied a fungicide in the last week, apply as soon as possible. As long as the current weather pattern persists, fungicides should be applied on a weekly schedule.
Standard protectant fungicides, such as EBDC or chlorothalonil are effective. Performance can be improved by adding Curzate, Acrobat, Previcur, or SuperTin. The add-in fungicides just mentioned should not be used alone. Gavel and Omega are two stand-alone products that are extremely effective against late blight.
For more information, call University of Idaho Extension personnel at the following numbers:
Treasure Valley: 722-6701 (Mike Thornton)
Magic Valley: 736-3600 or 423-6621 (Nora Olsen)

Posted on: June 21, 2004 by Jeff Miller
The weather in southerin Idaho has been extremely favorable for late blight. Disease forecasting models indicate that 2004 may be a late blight year. Apply protectant fungicides just prior to row closure and again 7 days later. After that, adopting a wait and see approach may be valid. Scout wet field areas weekly after row closure. If you have any questions, please contact Jeff Miller at 397-4181.
Minimizing Root-Knot Nematode Problems On Potato In This Sea
Potato Eastern Idaho
Posted on: September 24, 2003 by Dr. Saad Hafez
A severe winter is one of the characteristics for Idaho's weather. But, mild winter conditions during the current year followed by an early warm spring and a hot summer produced a perfect condition not only for the growth of potato but also for the 'unseen enemy' nematode. It has been a perfect condition for the nematode multiplication, resulting in severe damage on the 2003 potato crop.
Among all abiotic factors, temperature plays an important role on the nematode life cycle, feeding and multiplication rate. Deep frost and lower temperatures during the winter season reduce the nematode population and there by minimize the nematode damage on the succeeding potato crop. This year crop season is characterized by unusual mild winter with very early warm spring, which leads to the more nematode generations within a short period. This environment is highly congenial for the development of all nematodes. Although the nematode diagnostic lab can determine the initial nematode population before planting of potato, no method is available to determine the accurate population during the crop growth period. But, when there is a will there is a way. Yes, one of the ways by which growers can minimize the root-knot damage on potato is to harvest the crop early and not to keep the crop in storage. Adoption of such a practice will be highly useful to the growers whose field has a previous history of root-knot nematodes.

Pink rot
Potato Eastern Idaho
Posted on: August 20, 2003 by Jeff Miller
Severe pink rot has been identified in several fields in central and eastern Idaho. Plants appear wilted with leaves dying and plant lying down. This is different from the typical flagging symptoms associated with Verticillium wilt. Infected plants are showing lesions on the below ground stem that resemble severe Rhizoctonia. Infected stem tissue easily sloughs off. The pathogen grows from an initial below-ground stem infection up and down the stem. Tubers are becoming infected by the pathogen growing out the stolon or by direct contact if tubers are touching infected stems. Some fields have shown extremely high infection rates. In these cases, immediate vine kill is advised to prevent the pathogen from growing into healthy tubers. The severity of the problem is most likely caused by the extended high temperatures we have experienced the last several weeks. Maximum soil temperatures have been above 80 F for much of July and the early part of August. Extra water that may have been applied to help manage heat stress has compounded the pink rot problems. The University of Idaho would like to receive pink rot samples in order to determine fungicide sensitivity. Please contact Jeff Miller at 208-397-4181 or by email at jsmiller@uidaho.edu.
