Stripe rust
Posted on: May 6, 2015 by Bill Buhrig
Stripe rust has been found in a winter wheat field in Malheur County. The infected field had small patches of stripe rust but was not thoroughly distributed. This discovery falls in line with stripe rust being found in Canyon County. Work with your field consultants and incorporate good scouting procedures for your fields to develop a plan of action as necessary.
Please check out the links attached. One is from the PNW Plant Disease Management Handbook and the other is from Juliet Marshall with the U of I and has been linked prior on the PNWPestalert site. Both have great information on stripe rust.

Posted on: May 5, 2014 by Bill Buhrig
Alfalfa weevil are being found in forage alfalfa fields in Malheur County. They appear to be most prevalent in fields with older stands. Some fields have already been treated. Control options include applying an insecticide or harvesting the crop before damage becomes too great. If insecticides are used, be aware that the pre-harvest interval may be up to three weeks depending on the product used. Utilize proper scouting procedures in conjunction with your crop consultant to determine if you are approaching the economic damage threshold and what options for control may be best for your situation.

Spotted Wing Drosophila
Small Fruits Treasure Valley - Oregon
Spotted wing drosophila
Posted on: October 15, 2013 by Stuart Reitz
Spotted wing Drosophila has been detected in Malheur County. Larvae were found infesting raspberries collected from a homeowner’s garden in Ontario. Spotted wing drosophila (SWD), Drosophila suzukii, is an invasive insect pest of economically valuable small fruit and tree fruit crops that was first identified in the Western United States in late 2008. Spotted wing drosophila has previously been confirmed in 2012 and 2013 in neighboring counties in Idaho (Canyon and Payette) so the discovery in Malheur County is not unexpected. In those Idaho counties, it has been found infesting raspberries, grapes and peaches.
Spotted wing drosophila differs from the common drosophila species such as Drosophila melanogaster that occur in Pacific Northwest fruit crops in that it can attack healthy, undamaged ripening fruit; the common species will only attack overripe, damaged, or dropped fruit. Drosophila larvae in sound ripening fruit are likely to be spotted wing drosophila. Spotted wing drosophila have the potential to be a very serious pest of tree and small fruits. Commercial fruit producers and home gardeners should take all appropriate management efforts for this pest, including:
Monitoring: check fruit regularly for ripeness, damage and presence of SWD. Commercial or home traps are useful for monitoring for SWD adults, and may be useful for control.
Sanitation: remove and destroy infested and overripe or damage fruit
Early harvest: harvest as early as possible to reduce exposure to SWD
Netting: while not practical for large commercial operations, netting may be useful small fruits, and small or single trees or tree branches.
Pesticides: This pest is new and limited information is available on pesticides for control of SWD, but sprays must be timed to kill adults before they lay eggs in fruit.
Please see the following websites for information on identification, biology, monitoring and management of spotted wing drosophila for additional and specific information. Because of the relatively recent nature of this introduction, the provided information is subject to change as we learn more about the biology of this pest.

ODA restricts use of certain dinotefuran pesticides
Announcements Treasure Valley - Oregon
Posted on: June 27, 2013 by Stuart Reitz
June 27, 2013... The Oregon Department of Agriculture is restricting the use of 18 pesticide products containing the active ingredient dinotefuran while it continues the investigation of a large kill of bumblebees in Wilsonville and Hillsboro this month. By adopting a temporary rule, ODA is taking action, in an abundance of caution, to avoid the potential of similar large bee kills this summer due to specific pesticide applications.
“I have directed the agency to take this step in an effort to minimize any potential for additional incidents involving bee deaths connected to pesticide products with this active ingredient until such time as our investigation is completed and we have more information,” says ODA Director Katy Coba. “Conclusions from the investigation will help us and our partners evaluate whether additional steps need to be considered.”
The ODA restriction focuses on ornamental, turf, and agricultural pesticide products that are used by both professional applicators and homeowners. Products with the active ingredient dinotefuran registered in Oregon for other uses, such as flea and tick control on pets or home ant and roach control, are not affected by the restriction. ODA’s concern is focused on those uses that may impact pollinators.
By statute, ODA has legal authority to establish limitations and procedures deemed necessary and proper for the protection of bees and other pollinating insects. The temporary rule, which goes into effect immediately, will be enforced for 180 days, by which time ODA is expected to complete its pesticide use investigations of the Wilsonville and Hillsboro incidents. Those investigations will determine if the pesticide applications were in violation of state and federal pesticide regulations, and will assist ODA in addressing any potential future actions.
ODA’s Pesticide Program has established a website with more information on the dinotefuran restriction, including a list of specific products affected as well as instructions for those who may have purchased these products. Go to
Agricultural products containing dinotefuran include:
Product Name EPA Reg. No. Registrant
Safari 20 SG 33657-16-59639 Valent USA Corporation
Safari 20 SG 86203-11-59639 Valent USA Corporation

Posted on: March 14, 2011 by Steve Norberg
Onion Maggot Control Area in Malheur County
603-052-0360
Control Area: Onion Maggot -- Malheur County
(1) A control area is established within the boundaries of Malheur County for the protection of
the onion industry by the eradication or control of the insect pest known as the onion maggot.
This control area order is based on IPM principles first recognized and used by Malheur County
growers in 1957.
(2) The following methods of eradication and control are declared to be the proper methods used
in this control area order:
(a) All cull or waste onions in Malheur County shall be disposed of by a method approved by
this control order prior to March 15 each year; for onions sorted after that date until July 1, the
resulting cull and waste onions shall be disposed of within one week after such sorting;
(b) Disposal of cull or waste onions shall be accomplished only as set forth below:
(A) Disposal by covering in a dump site approved by the Oregon Department of Environmental
Quality (DEQ). Culls and onion debris shall be dumped and covered by at least 12 inches of
onion-free soil by March 15 each year;
(B) Disposal by animal feeding. Culls and onion debris shall be completely removed from
feeding areas by March 15 and buried under 12 inches of onion-free soil. Onions tramped into
the soil so they cannot be removed shall be plowed to a depth of 12 inches;
(C) Disposal by chopping or shredding. Chopped or shredded onion debris that is incapable of
sprouting may be returned to the field at a tonnage rate no higher than the DEQ-approved rate of
80 tons per acre and plowed to a depth where no onion parts are exposed on the surface;
(D) Composting. All onion debris shall be incorporated into the compost bed and completely
covered by 12 inches of onion-free soil;
(E) Disposal of residue in onion producing fields. Commercial onion fields where sort out bulbs
are left at harvest shall be disked to destroy the bulbs and shall be plowed to a depth of at least
12 inches by March 15 each year. Seed bulbs shall be disposed of in the same manner following
the last harvest. The owner of the field is ultimately responsible for compliance with this rule;
(F) If inclement weather prevents plowing, the culls will be treated with an EPA-labeled
insecticide currently listed in the PNW Insect Control Handbook at prescribed intervals until
proper disposal occurs.

Be scouting alfalfa weevil as numbers are increasing and I have seen fields with some damage.
Pest description and crop damage Larvae are about 0.375 inch long, yellow to green, with a white stripe down the back. They feed in and on the buds and leaves of alfalfa.
Sampling and thresholds
Treat when—
1. Thirty percent of plant terminals show feeding damage. Either cut and then treat stubble or treat the standing crop, depending on how close to cutting it is.
2. Damage is noticeable 1 week or more before estimated cutting time, and larvae exceed 10 per 90°-sweep, sometimes called a straight-line sweep).
3. Larvae number 20 or more per sweep (180° sweep, sometimes called a half-circle sweep). Thresholds based on larvae per sweep are a general guideline; weather, plant vigor, irrigation schedules, cutting date, history of weevils in the area, and a complex of other factors may determine whether treatment is warranted.
Management—chemical control
Most of these insecticides are hazardous to bees and should not be applied if bees are actively foraging in the alfalfa.
1. carbaryl at 1 to 1.5 lb ai/a. PHI 7 days for grazing or cutting. REI 12 hr. If pretreatment damage is extensive, cut alfalfa and treat the stubble for alfalfa weevil larvae. This product is not effective against adult alfalfa weevils. Do not apply more than once per cutting. Carbaryl may burn or yellow hay under some conditions, and applying to wet foliage or during high humidity may injure tender foliage. Latex-based formulations, such as Sevin XLR Plus, are less hazardous to bees.
2. carbofuran (Furadan 4F) at 0.25 to 1 lb ai/a for larvae and 0.5 to 1 lb ai/a for adults. PHI for grazing or cutting is 7 days at the 0.25 lb ai/a rate, 14 days at 0.5 lb ai/a, and 28 days at 1 lb ai/a. REI 48 hr. Do not apply more than once per season and apply only to pure stands. Do not move bees into alfalfa fields within 7 days of application. Do not apply near waterfowl nesting and feeding areas.
3. chlorpyrifos (Lorsban 4E) at 0.5 to 1 lb ai/a. PHI for grazing or cutting is 14 days at 0.5 lb ai/a or 21 days above 0.5 lb ai/a. REI 24 hr. Do not apply more than four times per season or reapply within 10 days of an earlier application. Minor phytotoxicity possible on young, tender, rapidly growing plants.
4. cyfluthrin (Baythroid 2) at 0.025 to 0.044 lb ai/a. PHI 7 days for grazing or cutting. REI 12 hr. Do not exceed 0.05 lb ai/a per cutting or 0.2 lb ai/a total per season.
5. dimethoate at 0.25 to 0.5 lb ai/a. PHI 10 days for grazing or cutting. REI 48 hr. For suppression only. Do not apply during bloom or exceed one application per cutting.
6. gamma-cyhalothrin (Proaxis) at 0.01 to 0.015 lb ai/a. PHI 1 day for forage harvest or 7 days for hay harvest. REI 24 hr. Do not exceed 0.015 lb ai/a per cutting or 0.06 lb ai/a per season. Do not apply within 25 ft of an aquatic habitat, 150 ft if applied by air, or 450 ft if applied by ULV.
7. indoxacarb (Steward) at 0.065 to 0.11 lb ai/a. PHI 7 days for cutting. REI 12 hr. Do not exceed one application per cutting or 0.44 lb ai/a total per season. Not for seed alfalfa.
8. lambda-cyhalothrin (Warrior) at 0.02 to 0.03 lb ai/a. PHI 1 day for forage harvest or 7 days for hay harvest. REI 24 hr. Apply only to pure stands and avoid applications when bees are actively foraging. Do not exceed 0.03 lb ai/a per cutting or 0.12 lb ai/a per season. Do not apply within 25 ft of an aquatic habitat, 150 ft if applied by air, or 450 ft if applied by ULV.
9. malathion 5 EC at 0.75 to 1 lb ai/a. PHI 0 days. REI 12 hr. For alfalfa weevil larvae only. Not effective below 65°F.
10. methomyl (Lannate LV) at 0.9 lb ai/a. PHI 0 days, 7 days for grazing or cutting. REI 48 hr. For alfalfa weevil larvae only. Do not exceed 10 applications per season or 3.6 lb ai/a total in one season.
11. permethrin at 0.1 to 0.2 lb ai/a. PHI 0 days at 0.1 lb ai/a or less, 14 days at more than 0.1 lb ai/a. REI 12 hr. Do not exceed 0.2 lb ai/a per cutting.
12. phosmet (Imidan 70-W) at 0.7 to 0.93 lb ai/a. PHI 7 days for grazing or cutting. REI 5 days. Do not apply more than once per cutting or apply during bloom. Do not use latex- or pineolene-based adjuvants.
13. zeta-cypermethrin (Mustang) at 0.028 to 0.05 lb ai/a. PHI 3 days for grazing or cutting. REI 12 hr. Wait at least 7 days to reapply. Do not exceed 0.05 lb ai/a per cutting or 0.15 lb ai/a per season. Do not apply within 25 ft of an aquatic habitat or 150 ft if applied by air.

Irrigation Conference:
Farmers and ranchers who might be thinking of purchasing a sprinkler system, or already use sprinklers in their operation should plan to attend the Sprinkler Irrigation Conference being offered by Oregon State University Malheur County Extension. The conference will be held at the Four Rivers Cultural Center in Ontario on January 6, 2009, from 8:30 a.m. to 2:45 p.m. For certified crop advisors 5 CEU's are available in the area of "Soil and Water".
According to Steve Norberg, Field Crops and Watershed Management Agent at the Malheur County office, experts in the field will be presenting timely information that will be useful to growers as they make plans for new sprinkler irrigation systems and improve on the systems they already have in place.
Growers will learn some of the advantages of using sprinklers in their operations, along with a local grower panel discussion, a segment on TMDL, and other topics such as reduced tillage systems with sprinklers, soil moisture monitoring/scheduling, runoff as impacted by irrigation systems, wheel track management, costs of pivots, followed by lunch, courtesy of several sponsors.
In the afternoon session, growers will receive information on working with their local irrigation districts, nutrient savings when using pivot irrigation, trouble-shooting sprinklers, some options with sprinkler systems, electrical options and programs and Environmental Quality Incentive Programs (EQIP) concerning irrigation.
If possible, please contact the Malheur County Extension office at 881-1417 by January 2, 2009 to RSVP.

There is a frost warning for this evening in the Treasure Valley. With many fruit trees blooming and other crops breaking it could cause damage. If the temperatures fall lower than 28 degrees over ten percent of flowers present on the fruit crops will be destroyed. Other crops could be stunted. Orchardists use heaters if available, or turn on wind machines. If you do not have use of these machines overhead sprinkle your trees this will create a protective cover of ice over the buds and blossoms. Remember that ice forms at 32 degrees and will insulate your future crop.

Iris Yellow Spot Virus
Onion Treasure Valley - Oregon
Posted on: July 27, 2005 by Jerry Neufeld
Lynn Jensen from the Oregon State University, Malheur County Cooperative Extension Office is reporting that Iris Yellow Spot Virus has been identified in onion fields in the Treasure Valley area including fields in Weiser, Fruitland, Ontario and Nyssa. There are currently no known fungicide treatment options for this virus. The virus is transmitted by onion thrips. Growers should keep their fields as stress free as possible by keeping thrips populations in check and by maintaining good irrigation practices.

Minimizing Root-Knot Nematode Problems On Potato In This Sea
All Crops Treasure Valley - Oregon
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.

Cereal Leaf Beetle Larval Hatch Starting
Small Grains Treasure Valley - Oregon
Posted on: May 8, 2003 by Ben Simko
Cereal Leaf Beetle (CLB) larval hatch is just beginning in spring grains near Adrian, OR and in winter wheat near Fruitland, ID. Adults, eggs and a few 1st instar larvae were observed in preferred hosts of spring barley but also in Brundage variety winter wheat. CLB counts collected in a Steptoe barley field near Adrian had average egg numbers at 3 per plant. A winter wheat field near Fruitland had average egg levels at 0.8 per stem or tiller. Based on thresholds established in eastern US production areas the barley field has reached an economic threshold but the winter wheat is at sub economic levels at this stage. Fieldmen and growers are advised to monitor populations of CLB and the larval hatch to assess potential economic damage to grain crops. See CLB Reference Page for more information on identification, action thresholds and crop protection chemicals. USDA APHIS staff are looking for a fields in Oregon for potential biocontrol release site of beneficial CLB parasites. For more information contact the Malheur County extension office at 541.881.1417.
