In late 2018, NEWA’s Coordinator, Dan Olmstead, and its creator, Dr. Juliet Carroll, concluded an assessment of a 2017 user survey. They, and the NEWA State Coordinators, reviewed user demographics, website content needs, and user experience before passing it on to Cornell’s Survey Research Institute.
The electronic survey included a subset of questions first asked in the 2007 survey. A summary of the 398 participants from 14 states provided a clear picture of NEWA’s impact. A more detailed summary has been shared in four posts at the NEWA Blog http://bitly12UatlMMW
Here’s the bottom line:
-NEWA is a reliable and trusted source of information among uses.
-All respondents said they would recommend NEW to other growers.
-NEWA provides reliable IPM information to support responsible management practices, enhance decision-making, and increase awareness of risks.
-96% of users say NEWA improves the timing of pesticide applications.
-NEWA has a positive impact on IPM practices.

Fewer vegetable than fruit models are available on NEWA. Cabbage maggot and onion maggot models are popular among growers (Fig. 2). Use percentages were based on the number of respondents to disease and insect model questions, which were 35 and 20, respectively. NEWA vegetable tool development is an area for future growth. In addition, promotion and education on how to use existing vegetable tools would increase use.

When putting the above statements into dollar figures, consider this:
Growers are saving money on an annual basis—an average of $4329—by reducing use of pesticide spray.
Estimated savings from crop loss, again on average, was $33,048.
Who uses NEWA? 75% are growers and 60% of them manage diversified farm operations.
20% of respondents managed farms smaller than 10 acres.
57% of respondents managed farms between 11 and 1000 acres.
4% had farms greater than 1000 acres.
Most NEWA growers grew apples, but a majority produced two or more commodities such as other tree fruit, grapes, berries, and tomatoes. Existing fruit and vegetable forecast tools will soon be joined by additional tools for field crops and ornamentals.
NEWA also provides links to other tools such as NOAA radar maps, USDA drought maps and websites that target particular problems like late blight or cucumber downy mildew.

Our new Spotted Lanternfly video, Have YOU Spotted Lanternfly Egg Masses was just posted, but it has already reached the number two spot. This invasive insect is getting a lot of attention and we need your help to keep track of it in New York.
Boxwood blight, Cylindrocladium buxicola, was first identified in 2011 when submitted samples were examined at the Connecticut Agricultural Experiment Station. This marked the first confirmed cases outside of the UK and New Zealand. Since then, it’s been found on many cultivars of boxwood, Buxus spp., up and down the east coast.

Now, it’s not only showing up in many downstate counties and Long Island, but completely decimating formal gardens and landscape nurseries. With various landscape and cutting uses, Boxwood is a million dollar plus industry, including its use as a major component in holiday wreaths and decorations.

While boxwood blight might not be a concern in your yard, you’d notice its loss in many landscapes. This is a major concern of landscapers, horticulturalists and growers.
Boxwood blight shows up as dark brown spots on leaves. These lesions enlarge with dark borders until they merge with others. By then an entire leaf—and many nearby—may be covered. These browned out or straw-colored dead leaves drop in record time. “That’s why they call it a blight.”
Stem infection also occurs and shows up as long black lesions. This FUNGAL DISEASE forms sporadochia (fruiting structures), visible with a hand lens. In layman’s terms, sporadochia produce sticky spores—nasty seeds of destruction if you’re a fungal disease! Spores happily spread by wind, rain, splashing water, or by hitchhiking on you, your lawnmower and rake, your dog, even your favorite garden birds.
Why this sudden outbreak? Anyone who suffered through this swampy summer can guess. According to Cornell Alum and New York State Climatologist, Mark Wysocki, “This is more typical for the Gulf Coast states.” Syracuse, for example, sweated through 531 hours when the dew point, a standard measure of humidity, was at least 70 degrees. That’s more than double the number of sticky hours of the next closest year, 2005.
THIS CHART SHOWS # OF HOURS OF DEWPOINT >= 70 at Ithaca Tompkins Airport by year 1996-2018
With relatively new pests, IPM and conventional treatment options aren’t time-tested. Other factors such as soil health, over or under-watering and winter injury increase susceptibility, but this year’s humidity has come at a high cost to boxwood.
For more on boxwood blight, here are two great resources:
“I already found a tick on me!” – many people across NY
Many New Yorkers still equate tick activity with summertime, but blacklegged ticks, the ones that carry Lyme disease, anaplasmosis, babesiosis, Powassan virus, and Borrelia miamyoti, are most active in the spring and fall. (They can actually be active year round if the temperature and humidity levels are just right. Thus the heavy activity on the warm days in February.)
The goal is to prevent ticks from becoming embedded in the first place. But if you do find an embedded tick, remove it properly!
And in the springtime the blacklegged tick nymph turns to thoughts of questing. And nymphs are small. Poppy seed-sized small. If you are not intentionally conducting a daily tick check, you could easily miss one. And even if you are intentionally looking, one can occasionally get through your visual defenses. Which is why I was able to take this tick removal video after finding this tiny nymph on my leg when using my fingertips to search by feel. Since Powassan virus can be transmitted after 15 minutes of the tick being embedded, the incentive for not being bitten has risen dramatically.
Which brings us to the use of clothing treatments to protect ourselves. Permethrin is a pesticide that can be applied to clothing, footwear and gear before exposure. Researchers for the Center for Disease Control recently conducted a study showing how permethrin interferes with blacklegged, American dog, and lone star ticks’ ability to move and, thus, to bite. Read about it here.
Now the easiest option is to buy pretreated clothing or have your clothes professionally treated. The TickEncounter Resource Center has an excellent section of their website about tick repellent clothes, including where to get them.
For DIYers, permethrin can be purchased at many sporting goods and big box stores as a liquid or aerosol spray. But it must be applied safely and correctly. I try not to react in horror as people tell me they will spray the clothes they are wearing just prior to walking out the door. This product must NOT be applied to clothing while it is being worn. Or when one’s husband announces that he left his newly treated clothing in the basement. (And, yes, he sprayed the clothes down there too.) Permethrin must be applied outdoors. Don’t take my word for it. This information, and more, is found on the label. Let’s take a close look at the label from a commonly found product. (Does not imply endorsement.)
The label is the law and will tell you everything you need to know about using a pesticide correctly and legally.
The label, which is vetted through the EPA and, in NY, the DEC, provides information on the following topics (with a few examples thrown in):
Signal Word – this is your clue to how dangerous the pesticide is. To put it simply, categories include Caution (slightly toxic), Warning (moderately toxic), and Danger (highly toxic). This formulation of permethrin is labeled Caution.
DIRECTIONS FOR USE – includes, but is not limited to:
SHAKE WELL BEFORE USING. (Emphasis theirs. It must be important!)
This product must not be applied to clothing while it is being worn. Under no circumstances should bare skin or clothing on the body be treated. (Emphasis also theirs.)
Make all applications outside.
STORAGE & DISPOSAL
Store in a cool, dry place inaccessible to children.
Never place unused product down any indoor or outdoor drain
PRECAUTIONARY STATEMENTS – includes “Do not use on humans.”
FIRST AID – in case you didn’t follow the precautionary statements.
This product is extremely toxic to fish and other aquatic organisms.
We hit just some of the highlights, but it is all important. The label not only provides suggestions for using the product safely – the label is the law. That too is on the label: “Buyer assumes all risks of use, storage or handling of this product not in strict accordance with directions given herewith.”
So what is one to do? Why, follow the label of course. Decide which clothes you might wear into tick infested places and “select an outdoor area protected from the wind, spray outer surfaces of clothing (while not being worn) with a slow sweeping motion to lightly moisten the surface of the fabric, holding pump at a distance of 6 to 8 inches. Treat outer surfaces of each outfit, front and back, for 30 seconds on each side and allow to dry for at least 2 hours (4 hours under humid conditions). Pay particular attention to socks, trouser cuffs, and shirt cuffs.”
Then plan for the next application. “Clothing should be retreated after six weeks or after the sixth laundering to maintain adequate protection” I both mark the day I sprayed in my calendar and schedule an appointment for six weeks later.
By the way, professionally treated clothing also has a label, often found on the hang tag when purchased. Be sure to follow those instructions carefully as well.
If you’ve read our other posts on the blacklegged tick (aka the deer tick), you might guess—and rightly so—that it’s the tick that’s been on our radar the longest; the one we (still) give most of our time and attention to. And all for good reason.
Sheer numbers (how much Lyme disease we’ve seen; what the co-infections are and how commonplace they are; its reputation as the “great imitator”) keep the blacklegged tick in the spotlight. Meanwhile, with the exception of Long Island, the lone star tick is rarely seen in the metro New York area and points north. But it has colonized some islands off Connecticut and established a toehold on Cape Cod in Massachusetts.
The lone star tick is on a roll, with its own suite of diseases and syndromes, some still mysterious. (Credit CDC)
Indeed, the lone star tick’s potential for harm could, somewhere down the pike, become a force all northerners face.
And consider this: though deer serve as a great food source and taxi service for ticks, they are immune to Lyme disease. Not so with the lone star tick. Because given the right circumstances, it can kill even deer.
So … what diseases or conditions does this tick carry—and could any be fatal to people? Here’s the short list:
Ehrlichiosis is nasty. Upward of two percent of those who get it might die.
Tularemia is nasty too, though less so than ehrlichiosis.
Heartland virus is rare—and most people who do get it have mild symptoms; perhaps none at all. But yes, some will die.
Alpha-gal syndrome? Perhaps—especially if you don’t know it for what it is. While the symptoms can be frighteningly intense, not everyone reacts with that same level of intensity. Plus this syndrome’s transcontinental spread in places lacking lone star ticks leads to yet-unanswered questions.
So how about STARI, or southern tick-associated rash illness—can it do you in? My careful search turned up zilch, zip, zero. Doesn’t mean STARI won’t send you to an early grave. But if it could, I can’t find credentialed scientific sources to back up such a claim. You’ll be interested to know, though, that the rash STARI stands for can, on the surface of things, make you think you might have Lyme disease. And more unanswered questions: as of August 2017, the pathogen that causes STARI remains unknown.

We don’t have to go to wild places to find wildlife. A surprisingly wide range of species can be found in our sities and towns, from familiar animals like the raccoon to more exotic ones like the mountain lion. – Roger Tory Peterson
When I was younger, raccoons were my favorite animal. It was hard to resist their clever little hands and cute bandit masks. My stuffed raccoon was named Rickie. Even when I was old enough to learn about rabies, my love didn’t wane. But then, when taking a wildlife rehabilitation workshop, I learned about Baylisascaris procyonis (raccoon roundworm), an intestinal parasite passed in raccoon poo.
The speakers at that workshop recommended using a blowtorch to kill the eggs of this intestinal parasite which, terrifyingly, can enter our eyes and nervous systems. The cuddly raccoon lost its place in my heart.
My love-hate relationship with raccoons came to mind when I saw the CDC has released a fact sheet on raccoon latrines and Baylisascaris procyonis. I do work quite a bit with school and child care facilities with their obligatory playgrounds. The CDC notes that “young children or developmentally disabled persons are at highest risk for infection, as they may be more likely to put contaminated fingers, soil, or objects into their mouths.” But they fail to point out that sandboxes can serve as a raccoon latrine. (It’s listed as a possibility here.) Of course, cats, which carry their own suite of parasites, are more likely to use sandboxes as their own personal litter box. It’s good IPM to prevent all types of animals from accessing your sandboxes.
The idea is good, but the implementation is lacking. Without securing the tarp, animals can easily slip under it. Photo: Joellen Lampman
No need to rid your property of sandboxes — indeed, there are sensory and group play opportunities with sandboxes (just Google “sand play activities”). But you must prevent animals from gaining access. Here’s how:
Keep sanitation a priority to avoid attracting wildlife – ensure that trash is cleaned up and put in a sealed container at the end of each day. (This will also help with other pests such as rats and yellow jackets.)
Have a “no food in the sandbox” rule – there is no need to provide an enticement for local animals to check out the box.
Have a solid box bottom — not only will this help prevent sand loss, but it keeps critters from burrowing in from underneath.
Have a durable cover on your box and make sure it is only uncovered during playtime.
Pest proof your buildings (including outbuildings) to reduce den sites. Raccoons will gladly set up facilities in your attic or garden shed.

If you find a latrine, check out the CDC fact sheet that includes information on cleaning it up while protecting your health. (Spoiler alert: they also recommend using a propane torch, since chemicals will not kill the eggs.)
Just a note that raccoon latrines can be found in other areas, including (yikes!) inside buildings. Be sure to pest proof your buildings to prevent raccoons (and squirrels and bats and birds) from making your building their new den.

by Mary M. Woodsen Comments Off on Pollinators, awards — and IPM
It takes teamwork — whether you’re a bee or a researcher. (Photo Sasha Israel)
New York, like the rest of the world, is highly dependent on the hundreds of species of crop pollinators that collectively contribute roughly $170 billion a year to the global economy. Many are in decline and under threat in New York and elsewhere.
That’s why Dean Kathryn J. Boor ’80 recognized the Cornell Pollinator Health Team for their outstanding outreach accomplishments in a ceremony that celebrated research, extension and staff excellence.
On hand to accept from Dean Kathryn Boor (L) were (L-R) Jennifer Grant, Bryan Danforth, Dan Wixted and Scott McArt.
The seven-member team includes entomologists, extension outreach specialists and pest management experts — one being NYS IPM‘s director Jennifer Grant.
The team provides critical extension and outreach on pollinator declines, including information on
optimal habitats for honey bees, native bees, and other pollinators
diseases that afflict bees
how pesticides affect bees — other pollinators too
what to do when your honey bees are in decline
Hi. I’m a hover fly and I pollinate lots of plants too. Plus my larvae eat aphids for breakfast, lunch and dinner. And no, I won’t sting you. (Photo credit Susan Ellis.)
With its focus on extension and outreach, the team has given more than 70 extension talks over the past three years in New York and elsewhere on pollinator health, bee diversity, integrated pest management practices and pesticide recommendations that minimize risks to bees — to all pollinators, in fact. Their audiences have included beekeepers, farmers, and lawmakers — as well as state and national organizations such as the New York Farm Bureau, the Audubon Society and Future Farmers of America.
“In three short years, the work of this team has made a notable impact both in scope and relevance to beekeepers,” Boor said at the ceremony. “The pollinator health team represents a model for how collaboration among different units at Cornell can lead to highly integrative and creative extension and outreach.”

by Abby Seaman Comments Off on Got late blight in your garden? Here’s what to do.
Some varieties of potato — Elba, Kennebec, Sebago, and Serran among them — have some resistance; they will slow but not prevent late blight infection. If late blight becomes prevalent in your area, fungicides can protect your plants.
But act quickly, applying fungicide before plants are infected. Why? Products available for gardens cannot cure existing infections.
Want to track where late blight has been found? Sign up for text or email alerts on the usablight.org web site.
What to do if you find late blight in your garden
Take immediate action — otherwise you’ll be a source of infection for other gardens and farms. Infected plants release hundreds of thousands of spores that move on the breeze. But first confirm that what you have is late blight and not another tomato or potato disease.
County Cornell Cooperative Extension offices can offer a diagnosis or can submit a sample through the usablight.org web site. Reporting your find on usablight.org and submitting close-up and in-focus photos can sometimes be enough for us confirm a late blight infection.
Though we hate to say it, if the rainy conditions we’ve had so far this season continue, some of us will lose the battle against late blight. If that happens, you can find some suggestions for how to prevent your garden from being a source of infection for the whole neighborhood in the video What to Do if You Find Late Blight in Your Garden.
Good luck! And here’s hoping late blight doesn’t find you this season.
Lesions on leaves, stems, and fruit — it’s late blight in full bloom.

by Mary M. Woodsen Comments Off on It’s Invasive Species Awareness Week all over the U.S.
It’s Invasive Species Awareness Week — now. Pay it heed. Invasive species, it turns out, are a huge deal in the US, in New York. Everywhere, in fact.
Coping with invasive insects, pathogens and the like have cost, in the US as a whole, upward of … OK, I’m hedging already. Is it $40 billion a year? $120 billion, maybe? The estimates vary widely.
What about global losses? Ahhhhh. Nailing those, especially vital ecosystem-regulating services, is where “difficult” morphs into “impossible,” for now and perhaps forever. It’s tricky, measuring something when it’s gone.
So what about the price here in New York? Unknown, though not for lack of trying.
Example: My admittedly quick-and-dirty search uncovered a 2005 report which noted that costs for eradicating Asian Long-horned beetle from New York City and Long Island had ranged between $13 and $40 million.
Killer beetle has distinctive markings. See something? Say something. Photo credit Kyle Ramirez.
Likewise in of 2005, New York spent about a half million dollars to control sea lampreys in lakes Ontario and Erie — with no end in sight.
More recently, in 2016, I learned that oak wilt — first discovered In New York in 2008 — has cost $500 grand to control. Some midwestern states spend over $1 million a year to control it. Pretty pricey if you ask me.
What helped here? Partly it’s the luck of the draw — oak wilt arrived decades ago, making inroads throughout the Midwest slowly but relentlessly. It can take time to recognize the true nature of a pathogen — or most any invasive pest. Then it’s a catch-up game to stay on top of it. If you can.
On the loose all over the Midwest — and now here. Photo courtesy Iowa State Plant Disease Clinic.
New York saw what had happened elsewhere and has aggressively surveyed (good IPM!) and eradicated infestations quickly while still small. But that $500 grand price tag? Yow.
Still, the economic costs of losing every (yes, every) oak would far greater.
Yet to come — what to if you find Asian long-horned beetle, oak wilt, and the like.

It’s summer; the goldenrods will be blooming soon, with bumble bees buzzing around them. Photo courtesy David Cappaert.
When we think about bees, we mostly think about honeybees … a European native brought here by the very first colonists. Now honeybees are struggling, hammered by a constellation of 20-plus diseases and parasites — not to mention a range of insecticides and fungicides.
About 450 species of wild bees also populate our fields and gardens. They have similar problems. And they’re losing habitat.
This is serious business: we depend on pollinators for at least one-third of our food supply. Altogether, these pollinators boost New York’s economy by $1.2 billion.
And consider all those other critters: flower flies and hover flies, wasps, butterflies and moths; even hummingbirds — they are legion, they work hard for their living; they help too.
NYSIPM funds educational projects like this. Photo courtesy Jen Stengle.
What to do? For starters, we can make all these helpers even more at home in our fields and gardens.
Indeed, it’s through bringing together everything IPM knows about host and pest biology and habitat; about pesticides and their EIQs; about habitat protection and biodiversity — these are the things we excel at, and these are what we’re putting into play now to find the answers we need.
Ah … answers. Such as?
Since protecting non-target organisms is core to IPM, we helped advise the governor’s Pollinator Task Force in crafting a Pollinator Protection Plan — itself informed by a national strategy to promote the health of all pollinators. And our flagship IPM Annual Conference highlighted an IPM problem-solution approach for the 100 participants: farmers, consultants, beekeepers (but of course), landscapers, researchers, policy makers, greenhouse growers, and more.
Check it out — not only because you care about your health and your food supply, but because you care about this beautiful world we live in.
