Are plants conscious? “We tend to think of plants as passive organisms, the backdrop for looking at more interesting animals roaming around in the foreground. But the world of plants is by no means docile, it is simply working on a separate time scale and in a different medium, and we’re only just starting to decipher it.” (Josh Davis, iflscience.com) https://bit.ly/2pQZjwr
Red meat allergy associated with tick bites could also be passed on by tiny mites. “After a series of strange medical cases, researchers discovered that bites from the lone star tick can induce a severe and persistent allergy to red meat. In the six or so years since this was identified, it has been determined that bites from multiple other tick species can also cause it. Now, evidence indicates that bites from another type of small, parasitic arachnid known as a “chigger” may do the same.”(iflscience.com) https://bit.ly/2zLQokc

Remembering with Fondness and Gratitude: Ray McNeilan

It is with sincere sadness we report that Ray McNeilan, OSU Professor of Horticulture and head of the Extension Master Gardener program from 1978 to 1996, died on October 4, 2018.
It is impossible to overstate the impact that Ray had on Oregon’s Master Gardener Program and on home gardeners across Oregon. He taught generations of Master Gardeners, was a gracious colleague to fellow horticulturists, and authored several books and countless Extension fact sheets.
Ray was instrumental helping to establish the Oregon Master Gardeners Association (comprised of individual, county Chapters), as a non-profit 501(c) organization dedicated to raising funds and supporting the Oregon State Master Gardener program.
Upon his retirement, he continued to volunteer his time and expertise to the Master Gardener Program and to the Oregon Master Gardener Association. In honor of his contributions, the Oregon Master Gardener Association funds a scholarship for an OSU Horticulture student, in Dr. McNeilan’s name.
His smile was huge, as was his heart. Together with his wife Jan (who was also an OSU Extension Professional, and the Coordinator of OSU’s Master Gardener Program from 2003 to 2007), the McNeilans helped to establish the Statewide Master Gardener Endowment Fund at OSU, which has been integral to keeping the program strong, to this day.
A giant in the world of horticulture, Ray was humble, generous, and always smiling. His legacy will live on in the many Master Gardeners he trained, the students who study horticulture at OSU via the Ray McNeilan scholarship, and the many colleagues he has supported and encouraged.
The metro-area Master Gardener program remembers Ray with fondness and deepest gratitude, knowing the significant, positive difference that he made to the OSU Master Gardener program, the gardening public and horticulture in Oregon!
In lieu of flowers, the family suggests tax-deductible memorial donations to the program closest to his heart: OSU Master Gardener Program Endowment, OSU Foundation, 850 S.W. 35th St., Corvallis, OR 97333-4015.

The Brown Widow Spider (Latrodectus geometricus) recently identified (October 2018) in Oregon City, OR, is a tropical species unlikely to survive outdoors in the northwest. The hourglass mark on the ventral abdomen is orange instead of red as on the Black Widow (L. hesperus). (http://cisr.ucr.edu/brown_widow_spider.html)
Almost everybody loves to hate spiders. Especially during the late summer and fall, when the males are dashing around the house searching for females.
Well, let me introduce the Brown Widow Spider, Latrodectus geometricus, a relative of the black widow. Now, people have another spider to worry about. (The western black widow, L. hesperus, is scarce in western Oregon, more abundant in the south and east sections.)
A first-ever record for Oregon, the brown widow was found in Oregon City earlier this year. It resembles an adult-sized version of an immature black widow, a variable combination of off-white, brown, tan and black. It can be challenging to differentiate between the 2 species until they’re more than half-grown. Finding an egg sac makes it easier; the brown widow’s is “spiky” whereas the black widow’s is smooth.

Trellis Rust on pear was submitted to the Clackamas County MG office last month (October 2018). To date, reported cases in the metro counties have been mild, with the unusual eruptions (“acorns”) on the leaf reverse of only a few leaves on each infected tree. (Client image)
An alert client submitted images of Trellis Rust on 3 y.o. pear trees to the Clackamas County MG office last month (October 2018), a disease first identified in Oregon during 2016. Signs, symptoms, and the alternate host (juniper) are quite different from those of the more common Pacific Coast Pear Rust (alternate host incense cedar).
The MGs reported the infection to Jay Pscheidt, the OSU Plant Pathologist. Here’s his response:
Looks like we have this disease on pear in Benton, Marion, Clackamas and Multnomah counties. I have not heard of any other places. No one has made mention of it on Juniper which is interesting in itself.
From our experience this year in the Corvallis area it has not been too severe on pear. A few leaves on a few trees. In the home landscape, leaf removal seems a viable option for the moment.
I suspect chemical management may help but timing is everything. Bonide Fruit Tree and Plant Guard RTS is registered for pear but also contains an insecticide in addition to a group 7 + 11 fungicide. It should have some activity on both scab and rust. But we don’t need to be spraying pear trees now as the spores are heading to the juniper alternate host. Infuse Systemic Disease Control is registered for juniper and may have some activity to prevent infection of rust. In other words, spray pears in the spring and junipers in the fall if you want to use chemical protection.

Message from State Master Gardener Coordinator Gail Langellotto:
“Several Master Gardeners and members of the general public have called on Extension to provide guidance on glyphosate use. Kaci Buhl (OSU Statewide Pesticide Safety Education) and Chip Bubl (OSU Extension Horticulture/General Agriculture) collaborated to develop a list of Q&As that might be helpful to MGs.” See the document below…
Glyphosate Questions & Answers
Kaci Buhl, Chip Bubl, Oregon State University Extension
What is glyphosate?
It’s a weed-killing chemical found in Roundup and many other weed killers. Like other herbicides, it is usually combined with one or many other ingredients to make the final product.
Does OSU have an official position for or against using glyphosate?
No. It is our mission to educate, not to legislate. We’re happy to answer questions and help find solutions using any legal, effective methods, while considering the risks.
Does glyphosate cause cancer in humans?
Maybe, at high enough doses. If it caused cancer at realistic exposure levels from using weed-killers, then farmers and other applicators would be the first to show this effect. The largest study ever published, looking at farmers and other applicators, found no association between glyphosate and solid tumors, including Non-Hodgkin’s Lymphoma (NHL).
That study found a potential association between glyphosate exposure and a certain type of blood cancer that was not statistically significant. Another study suggested that using fertilizers could account for this risk.
Why do regulators disagree about this?
They don’t. Not really.
The International Agency for Research on Cancer (IARC), an arm of the World Health Organization (WHO), determined in 2015 that glyphosate is a probable human carcinogen. That determination was surprising to many. IARC responded to critics by clarifying its intent – to identify potential hazards. They asked, “Can it cause cancer under any circumstances?” They group hazards based on the strength of evidence, not the potency of the carcinogen(s). They defer to national and international bodies to take the next step, which is risk-assessment. Risk assessment is based on expected levels of exposure and background cancer rates.
Many governments have published risk assessments about glyphosate, finding it is unlikely to cause cancer in humans when used according to the label directions as required.
International assembly of experts: FAO/WHO May 16, 2016
To put the IARC determination in context, they put the following items in the same category as glyphosate, Group 2A “Probable human carcinogens.”
Red meat
Indoor emissions from burning wood
High-temperature frying
Late-night work shifts
The following items were placed in a stronger-evidence category, “Known human carcinogens.”
Processed meats
All alcoholic beverages
Sunlight
Engine exhaust
Outdoor air pollution
The work of hazard identification is important, but it’s only the first step in understanding risk.
What about the other ingredients in Roundup?
Researchers reviewed the scientific literature on glyphosate, its major metabolite AMPA, formulated Roundup® products manufactured by Monsanto, and the surfactant POEA. They concluded that none of the components caused cancer. However, POEA can be harmful to a variety of aquatic wildlife (i.e. minnows, frogs, micro-organisms).
It can be difficult to determine the risks associated with other ingredients in pesticide formulations, including Roundup. This is because manufacturers are not currently required to identify “other ingredients” on product labels.
How have the courts ruled?
Courts have ruled in different ways on this issue. A California jury found Monsanto liable in August 2018 for causing a man’s cancer. The man used glyphosate weed-killers for years. The case has been appealed. In contrast, a federal judge in California ruled in June 2018 against the state’s case for placing warning labels on containers of glyphosate under Proposition 65. It would have required warnings about the potential for glyphosate to cause cancer. The judge cited a “heavy weight of evidence” that the risk was very low. The courts will likely evaluate more cases in the future.
Are foods with glyphosate residue safe to eat?
A tiny amount of glyphosate is not likely to cause harm, even if we eat those foods daily. There are residue limits for glyphosate on many fruits, vegetables, corn, grains, milk, and eggs. The FDA monitors the level of glyphosate on foods in the marketplace. So far, they have not found foods with too much residue, based on risk assessments. The dose makes the poison.
How can I reduce my risk?
If you choose to avoid glyphosate exposure altogether, seek out organic foods with the official logo from USDA. Glyphosate is not allowed to be used in organic settings. Use alternative methods of weed control. Talk with your local master gardeners about what’s working for them..
If you choose to use glyphosate weed-killers, make sure to follow the product label carefully. The label is the law. While glyphosate is poorly absorbed through the skin, some parts of the body are more absorptive than others. Minimize your exposure, and keep others away until sprays have dried. Talk with your neighbors about any concerns they might have, and take steps to accommodate their needs.
Ringing in the New Year! The ‘Master Gardener New Year’ That Is!
‘Ringing in the New Year’ may sound like we are pushing the seasons a bit – but for the metro-area Master Gardener program, October 1st is the beginning of our new year. Like the start of any new year – we take the time to reflect on the past and look to a promising future.

More Continuing Education Opportunities
Photo credit: Aaron Anderson, Oregon State University
Many have enjoyed and learned from the Master Gardener Training Webinars, brought to us from Brooke Edmunds and her OSU colleagues.
3 more timely topics are being presented as live webinars in 2018.
Monday 10/22 at 11am PT. Aaron Anderson (OSU Ph.D. student in the Department of Horticulture) will present First Look: OSU Research on Native Plants in the PNW Garden. Details and pre-registration here: https://learn.extension.org/events/3494
Monday 11/19 at 11am PT. Melodie Putnam (OSU Plant Clinic) will present on The Weird and Wonderful World of Plant Galls. Details and pre-registration here: https://learn.extension.org/events/3493
Monday 12/17 at 11am PT. Kaci Buhl (OSU Extension) will present on Weed Management in the Garden & Landscape: Understanding Herbicides. Details and pre-registration here: https://learn.extension.org/events/3501
We are excited to have a new online volunteer reporting system (via Qualtrics) to ease the process of submitting your volunteer hours and signed 2018-2019 Conditions of Volunteer Service form.
If you still need to submit your 2018 forms, please consider reporting using the online system – follow the links re-sent to you in an email from Marcia McIntyre on October 2nd
The online system prompts you through several questions to record your volunteer hours, a space to upload your volunteer log sheet, plus the opportunity for you to rate your satisfaction with the Master Gardener program. A separate link allows you to upload your signed, Conditions of Volunteer Service Form.
You still need to record your volunteer hours onto a Word or Excel form – but now you can upload those hours via the new online system.
NOTE: You can refer to your CERVIS log to track your hours – but you also need to log all CERVIS hours on your volunteer log sheet. Most “Program” hours are recorded in CERVIS. “Partner” events and activities are not recorded in CERVIS. Be sure to record all your volunteer hours and continuing education hours on your log sheet.
You know the rule about pesticides: “Read and follow label directions.”
Well, that catchy little phrase has become more critical than ever. Several popular home-use products have changed their formulations with minimal fanfare. There’s no indication of “new” on the label.
To compound the confusion, labels on the revised formulation closely resemble the old ones. Unless the user is more observant than average, it’s very likely something may go awry. The application method may have changed; the precautions may have been modified; and/or the end result may be different than expected.
Sevin is a familiar insecticide brand name for home gardeners used to control insects in lawns, on ornamental plants, and on vegetables. Sevin and the active ingredient carbaryl are practically synonymous. Recently, the active ingredient in some Sevin products was changed from carbaryl (a carbamate) to zeta-cypermethrin (a pyrethroid).” . . . This pyrethroid is less toxic to mammals but both carbaryl and zeta-cypermethrin are highly toxic to bees and aquatic species. The new label on Sevin Insect Killer states that it controls more pests than the old product containing carbaryl, which may seem great, but the product may also kill some of the good bugs like lady beetles (ladybugs).
Product labels often look very similar, even when the ingredients change. On the left is the recently released product containing zeta-cypermethrin; the former version on the right contains carbaryl.
Another very important difference is the time the products can safely be applied on fruits and vegetables before harvest (called preharvest interval or PHI). Following the PHI reduces your pesticide exposure when you eat the food. For fruits such as apples and peaches, the PHI for the zeta-cypermethrin Sevin is 14 days, but for the Sevin with carbaryl it’s 3 days. For other fruits and vegetables, the PHI for the new Sevin label may be shorter than the carbaryl label. Again, check the label.
When Roundup is no longer glyphosate
Another familiar pesticide name is Roundup, a product known historically for containing the herbicide active ingredient glyphosate. Monsanto, the manufacturer of Roundup, now produces an extensive line of Roundup products containing multiple active ingredients, rather than just glyphosate alone. Many of these products contain triclopyr or diquat in addition to glyphosate. Some don’t contain any glyphosate at all
“Roundup Landscape Weed Killer” is a new product which contains pendimethalin instead of glyphosate. It’s both a non-selective herbicide and a pre-emergent.
When Corry’s Slug and Snail Killer is no longer metaldehyde
In 2012, the active ingredient of the well-known Corry’s Slug and Snail Killer was changed from metaldehyde to sodium ferric EDTA, but the general look of the product box didn’t change. This relatively new active ingredient is less toxic and less attractive to dogs and still effective against snails and slugs. However, the amount users apply and how quickly it works both differ from the previous active ingredient. If you are familiar with the old product you may have noticed a change, but unless you read the label, you may not know why.
A Bonus Snippet on a different topic
MGs who volunteered this summer probably received multiple inquiries about the seemingly overabundant wasps this summer. Well, the general public is seriously confused concerning the differences among bees, yellowjackets, and paper wasps. When they see a somewhat elongated yellow and black insect, they assume “wasp;” that is, yellowjacket. (Don’t bother asking how I know.)
But yellowjackets have a near twin: European paper wasps, Polistes dominulus, invasive insects officially identified in Oregon years ago. Most paper wasps are mild-mannered whereas P. dominulus is nasty. To easily differentiate them from yellowjackets, check the antennae. Text and images are at “Invasive paper wasp responsible for increasing yellow jacket complaints.” (http://ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=11412 )
