This brief interlude of rain nudged me to remind folks about the excellent new boxwood blight resources that were published last spring by Oregon State University. There are fact sheets to help with diagnosis and management. In addition these resources are available in Spanish, poster, and mobile-friendly formats. Check the link for details. Robin

Japanese beetle outbreak detected in Washington County
August 29, 2016... A record number of invasive Japanese beetles have been detected in Washington County within the city of Portland this summer. To date, the Oregon Department of Agriculture has found 265 Japanese beetles in traps placed in the area as well as numerous live beetles causing feeding damage on roses and other plants. The evidence suggests a breeding population of the non-native insect has been established.
“What we know right now is that this infestation is localized yet producing enough adult beetles that we can find them feeding on roses and other plants in this area,” says Clint Burfitt, manager of ODA’s Insect Pest Prevention and Management Program. “Without community action, this pest will spread and cause an increased use of pesticides by homeowners and producers of agricultural crops such as cannabis, hops, nursery plants, and wine grapes.”
Additional traps have been placed in the vicinity of Northwest Saltzman and Northwest Thompson roads. It appears the infestation has been present for at least more than a year but not detected until this summer.
Japanese beetle is a major plant pest in other parts of the US. As a grub, it can be very destructive to turf. As an adult, the bright metallic green beetle with copper-colored wing covers will feast on a wide variety of plant material including trees, shrubs, flowers, fruits, and vegetables. It is a pest that can be destructive in urban and agricultural environments, and is also subject to agricultural quarantine regulations. ODA has been using an early detection, rapid response approach for years to find and eradicate populations of the pest. In the past, Japanese beetle has made its way into Oregon through air cargo carriers with multiple detections over the years near Portland International Airport. In recent years, ODA has conducted eradication projects in residential areas of Portland and Cave Junction.
No eradication plans have been made yet in response to the most recent outbreak. ODA will continue to trap for Japanese beetles in hopes of pinpointing the location of the breeding population and potential treatment next year.
“We encourage residents to cooperate with field technicians who are maintaining traps and to be aware that this infestation can be spread by the movement of plants, roots, and soil that originate from this area,” says Burfitt.

Rufus at the WxCafe® ponders on Perseid and the weather prognosis. Robin
Friday August 12
An excellent Perseid Meteor Show last night, with another one on the way tonight after the moon sets (target 2 - 4 am for best viewing). In the what-will-our-weather-be-like department, seasonal summer conditions will be the show, as well. Here's the latest.
Generally milder temps west side this weekend on into early next week because Nature's marine air conditioner will tap down temps with an onshore flow, esp west side of the Cascades, from Saturday through Tuesday. Here's where we have been getting two different long-range model outlooks.
Solution A: heat may rebuild again beginning next Wed the 17th (earlier than previously expected). Temps by Thu & Fri, Aug 18,19 will get uncomfortable as the hottest afternoons of summer may verify. A tap-down in the temps will occur over the weekend of Aug 20,21 as mid-level moisture from the south will trigger thunderstorms over the eastern basins and add muggy humidity readings across the PNW. Dry and summer-like all the way through to August 28.
Solution B: westerly flow aloft increases again (think July), with cooler temps moving back in after the Aug 20,21 weekend. Showers and much cooler weather arriving to present a rather cool, wet cycle in the Aug 23-27 period. This solution ties into the cold air mass over building over the Chuckchi Sea, NW of Alaska, which we pondered over a morning beverage earlier.
Your WxCafe (TM) will lean towards A - keeping summer alive with seasonal, dry and hot conditions to run out the Aug 18-28 period. Hey, definitely a more straight forward projection than that of our politicians.
Should the thunderstorm activity move in, FIRE issues will come into play across the eastern slopes of the Cascades. This, too, is seasonal for August.

Dr. Lloyd Nackley has accepted an offer to become the new Nursery and Greenhouse Crops Production and Management faculty member at the NWREC. Nackley will begin his work on September 16 after relocating his family from Davis,California, where he is currently a post-doc researcher.
Nackley’s appointment culminates a five-year vacancy in this key position at NWREC—following the resignation of Jim Owen when he accepted a new position at Virginia Tech University in 2011.“We are very excited to make this announcement and, finally, get this important faculty position hired,”said Mike Bondi, NWREC Director. “We appreciate everyone’s patience with the process. It has been a long road with the recession, tight budgets,and a failed search along the way. But, the important thing is that we had excellent candidates in our last recruitment pool and we are very pleased to have someone with Lloyd’s experience joining our staff at NWREC.”
Dr. Nackley has a PhD from the University of Washington (2012) in Plant Physiological Ecology and a B.S. in Environmental Horticultural Science at California Polytechnic State University (2003). In addition, he is completing his second post-doc research position. Nackley has a broad background and experience that should provide him with an excellent foundation to address the needs of nursery and greenhouse growers in theWillamette Valley. Nackley has researched bioenergy crops for the National Science Foundation, developed garlic growing practices for the Korean Department of Agriculture, investigated how climate change and invasive species were threatening citrus growers in South Africa, and provided research-based solutions for specialty crop growers challenged with water shortage, pollutants and pathogen issues in the California Central Valley.
Welcome to Oregon, Lloyd!
