sugarbeet root maggot
All Crops Treasure Valley - Idaho
Posted on: May 12, 2008 by Jerry Neufeld
Field representatives from the Amalgamated Sugar Company are reporting we reached the growing degree day threshold for sugarbeet root maggot fly emergence late last week in the Nyssa area. Adult sugarbeet root maggot flies will begin emerging and flying anytime now.
Adult flies will lay eggs near the sugarbeet plants 3 to 10 days after they emerge. After the larvae hatch they will begin feeding on the young sugarbeets. Potential maggot damage could be worse this year since there are so many replanted fields with small beets at the time the maggots are feeding. 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, contact your White Satin fieldman for further information.

Rimon Ovicide degree day applications
Tree Fruits Treasure Valley - Idaho
Posted on: May 7, 2008 by Tony McCammon
The Rimon label states that it wants to be on between 50-75 degree days(DD) in Western states. If we Include the success of the trials Wilbur Ellis completed with this product, appling material at 100 and 1000 DD,
The 1st generation has a window that could be from 50 to 100 DD giving large orchadists a little more time to cover their acres. The 2nd generation should be applied starting at 1000 degrees. Submitted by Tom Tankersly
Estimating DD with the projected forcast expect to reach 50 DD on Monday in most parts of the Treasure Valley.
Good Luck!

Potential Freeze Damage to Cereals
Small Grains All Locations
Posted on: April 29, 2008 by Steve Norberg
On Monday April 21 temperatures plummeted in the Treasure Valley Area. Readings at the Malheur Experiment Station went as low as 21 F. The effect on winter cereals in the area will be dependent on the stage of the crop on that day. Those fields that had the growing point above ground (jointing) when this freeze event came may have moderate to severe damage. Producers can split open some stems and check the developing head. If the head is green or light greenish in color and seems firm, it is probably fine. If the head is yellowish and mushy, it may have freeze injury.” Healthy tillers will help compensate for yield losses to main stems. The links below have a summary of growth stages, the temperatures required for wheat and barley freeze damage, primary symptoms and yield effects.

cutworms in sugarbeets
Sugarbeets Treasure Valley - Idaho
Posted on: April 24, 2008 by
Amalgamated Sugar Company Field Reps are reporting cutworms were found in sugarbeets near Bruneau and Grandview. There are many species of cutworms that attack sugarbeets, but all are nocturnal, so you may see injury but not readily find the insect damaging the plants. If you see skips in the field, dig around in the soil where you would have expected a plant and you will likely find the lower portion of a cut plant. Larvae are often found less than an inch below the soil surface near a damaged plant. If you have any questions, contact your Amalgamated Fieldman.
Tree Fruit Frost Alert through Tuesday
All Crops Treasure Valley - Idaho
Posted on: April 18, 2008 by Tony McCammon
Frost warnings that are in effect through Tuesday. Low temperatures will be dropping to the mid to low 20’s. Fruit blossoms and buds will be susceptible to losses.
See attached Table on critical temperatures for flower and bud damage.
Orchardists use heaters if available, or turn on wind machines.
Homeowners use overhead irrigation, but this can be costly. The idea is to cover the buds and blossoms with water that will freeze, forming an ice layer. Remember that water freezes at 32 degrees F, and a permanent, uninterrupted layer of ice throughout the frost period will insulate flowers and buds. The ice must remain until the daytime air temperatures rise above freezing.
The last freeze will occur 2 out of 10 years after May 4 at a temperature of 28 degrees or less in Payette County, May 6th in Emmett and Parma, May 13th in Weiser, and April 27th in Caldwell.
tree stages:
Apple Peach Cherry Apricot
Payette 1/2"green pink bud-swell bloom
Fruitland cluster pink bud-swell bloom
Parma pre-pink pink bud-swell post-blm
Emmett cluster bloom white bud post-blm
Sunnyslope cluster bloom white bud post-blm
A 10% loss of a tree’s flowers may be tolerable for some growers. They may consider it as a thinning technique this year.
As you have seen we have had a cool spring thus far and are quite a bit behind what we have been in previous years. If this keeps up it may give growers the upper hand on coddling moth this year.
DD Temperatures as compared to the last 3 years
Here are DD from March 1 for the past years as of April 18 AM each year in Payette. Courtesy of Bill Ford:

New Potato GAP Website and Manual
Potato All Locations
Posted on: April 17, 2008 by Nora Olsen
The University of Idaho has designed a new comprehensive organizational manual and website for potato growers to help simplify the necessary requirements to successfully pass the USDA GAP Audit. At the website you can easily access the documents and make necessary changes appropriate to your farming operation. Documents also include examples of employee policy forms in both English and Spanish, Standard Operating procedures (SOP) as related to the current Audit, and additional website information. All information is present on the website to compile a hard-copy manual in a 3-ring binder with all related documents inserted.
The website is:
http://www.kimberly.uidaho.edu/potatoes/gap.htm
When changes occur to the audit or with the documents provided at this website, an email notification will be sent via PNWPestalert. Feel free to contact me directly regarding suggestions for the website and documents (Nora Olsen, 208-736-3621; norao@uidaho.edu).
Fungicides applied with Herbicides / stripe rust control
Small Grains All Locations
Posted on: March 31, 2008 by Juliet Windes and Brad Brown
We have had several questions in regard to early application of fungicides timed with herbicide applications and effectiveness in either increasing yield or providing disease protection. I only have 2 years worth of data (2 PDMRs) that directly address this question in spring wheat, which can be accessed at the South-central / Southeast Idaho Cereals website: http://www.ag.uidaho.edu/scseidaho/ under “Publications”. In 2006, we had enough late season stripe rust to damage yield in a very susceptible spring wheat variety. In the 2006 experiment, we saw a 1.3 bu increase with reduced rate (7 fl oz/A) of Quilt applied at herbicide timing and a 2.8 bu increase with (6 fl oz/ A) Headline applied at herbicide timing over the untreated control. We have NOT seen a statistically significant yield benefit with application of fungicides at herbicide application in 2006 or 2007, where the plants were in the 4-5 leaf stage at time of herbicide treatment. In 2006, where stripe rust was present at damaging levels late in the season, early application of Headline and Maestro at Feekes 3 did not reduce stripe rust over the untreated control (63.8% leaf area affected with early Headline versus 65.6% in the untreated control). Disease control with Headline alone at Feekes 8 resulted in 26.3% leaf area diseased and 82.5 bu/A as opposed to the early Headline treatment at 63.8% disease, and 72.5 bu/A. The yield and disease differences were significant at the 5% level.
In 2007, we did not have significant stripe rust. In experiment 2 (2007) we saw a 0.9 bu increase with 6 oz/A Headline, a 1.0 bu increase with reduced rate of Quilt (7 oz/A), and 1.3 bu decrease with a reduced rate of (6 oz/A) Stratego, when these fungicides were applied with herbicides. For Quilt, the rates were at a ½ rate of 7 fl oz/A at herbicide application versus 14 fl oz/A for full application at heading. Headline was applied at 6 fl oz/A with an herbicide and at 6 fl oz/A at heading. Stratego was 6 fl oz/A with herbicide or 10 fl oz/A at heading. Obviously, results may vary depending upon year and location, and multiple replicated trials over several years will give us the best answer. Talking with our BASF rep, early Headline recommendations are full rate (6 fl oz/A), for which they say they consistently (80% of the time) see 2-3 bu/A increase, and more often an average 6 bu/A increase in yield in unreplicated on-farm trials in wheat and barley.
In general, fungicides are recommended to control disease and protect yield when there is disease in the area; for example, as soon as stripe rust is present. In varieties that are very susceptible, that may mean an early protective fungicide application in with the herbicides when stripe rust or other diseases are in the area. However, in many cases, effective disease control and yield protection is achieved with one application to protect the flag leaf and / or the developing head, as late as allowed by the label. In the past, when disease becomes an issue, the greatest benefit to yield is application between flag leaf emergence and flowering, depending upon when the disease is present. Experiments in Kansas do not support split applications of fungicides to control disease. In years with low disease pressure, an overall 2.5% increase in yield was seen with split applications of fungicides, but fungicide applications were NOT timed for application with herbicides (Erick De Wolf, Bill Bockus, Bob Bowden, Kansas State University).
I do not think there would be any benefit of foliar fungicides for control of root rots, as those that are "locally" systemic are not readily translocated down into the root system. Any systemic translocation will more likely be in an upward direction, so control of root rots is highly unlikely. Root rot control would be best managed with seed health practices, such as in-furrow fertility and seed treatments, even with second-year grain. As far as second year of wheat or barley, if there are foliar pathogens present early (and it depends on the disease, like scald in barley), then I think there may be some benefit in disease control, but little benefit in yield. Diseases like scald and spot blotch tend to dissipate with warmer, dryer weather anyway. So I am not recommending foliar application of fungicides simply because a grower went back-to-back grain. Spraying fungicides for disease control is really only effective when disease is present and only after flag leaf emergence to heading. There seems to be no real benefit from 2 applications of fungicides within a season. Appropriate rotation and plant health practices remain the best insurance for a healthy crop (in our area). Fungicides are effective when disease threatens yield and the best yield protection comes after flag leaf emergence, but especially at heading to flowering.
DO NOT delay weed control applications to target potential disease problems. You will lose more yield to weed competition than gain by trying to target an early season fungicide application.
At current prices, a 2-3 bu yield increase should pay for most fungicides when incorporated into the herbicide treatment. However, in our area, we usually have very little foliar disease pressure. In areas where disease pressure can be significant early in the season (say, stripe rust in the Palouse), then I would consider early-season application based on significance of disease in the area. However, routinely applying low-levels of fungicides for “just-in-case” protection may contribute to the occurrence and buildup of fungicide resistance in fungal populations and is counter to the integrated pest management principals developed to reduce pesticides in the environment and we need to carefully consider any additional input costs.
