Eat local! For towns and cities small and large, the eat-local movement is a boon for farmers and consumers alike. You (the consumer) get your veggies fresh, while you (the farmer) can build a base of local buyers who know your products.
Tomatoes, cukes, and sweet peppers. Lettuce and spinach, arugula and swiss chard. For farmers who grow them, the season is always too short—and winter too long. Now some have adopted the high-tunnel approach to get ahead of the game.
These tomatoes are just getting traction. Next up….
Ripe local tomatoes … ready for you.
And what is a high tunnel, exactly? Uh … well, I’ll grant you there’s no “exactly” to many a thing—high tunnels included. But whatever the specifics, they have much in common. For starters, this type of greenhouse is usually a plastic covered structure with less environmental control, relying on passive ventilation for cooling.
But like everything in agriculture, high-tunnel crops have can have insect pests. Plant pathogens. Weeds.
How do we help? Let us count the ways. Crafting a solid IPM plan is a great place to start. The plan lays out practices that help prevent pests, be they diseases, weeds or insects. Choosing pest-resistant varieties helps lessens the need for pesticides. Ditto with becoming familiar with a range of biocontrols while you’re still ahead of the game. Then there’s getting the ID’s right: learning the appearance or symptoms of pests that just happen to be checking out the premises. Once you’ve nailed the IDs, it’s time to scout early and often.
Diversifying and rotating crops plays a big role too. So does getting watering, ventilation, and fertilizing down to an art—a must-do, since too much or too little of any of these can encourage those pests you are trying to control.
Next time you are buying local – ask your local farmer how they include IPM in their production. You’ll find they are all doing their best to grow beautiful, delicious veggies for you.

by Mary M. Woodsen Comments Off on New Field Crops and Livestock Coordinator Joins NYS IPM
Greetings! I’m Jaime Cummings, the new Field Crops and Livestock Coordinator at NYS IPM. My job? To work with field crop and livestock farmers on more than 3 million acres statewide who grow corn, hay, and other field crops and contribute to New York’s livestock industry. These farmers know all too well the problems that come with insect, disease and weed pests—problems that can change year to year.
They need IPM. Which means that each person who lives in New York and eats or drinks anything produced on a farm also needs IPM.
Meet Jaime Cummings. Farmers, you’ll be seeing a lot of her soon.
My background is in plant pathology, and I come from Cornell’s Field Crops Pathology program. While there I focused on field research for dealing with plant diseases and mycotoxins (aka fungal toxins). I also provided diagnostics for statewide disease surveys on all major field crops. Along the way I also earned my Certified Crop Advisor certification (CCA) for the Northeast.
Integrated Pest Management for Field Crops and Livestock
Field crop and livestock farmers in New York face problems both new and old. For starters, unpredictable weather patterns can favor a different spectrum or intensity of disease and pest problems that vary from one year to the next. Meanwhile, invasive pests of all sorts are ever knocking at our borders. It’s critical to know not only how to address each issue, but also know when it’s economically feasible and environmentally responsible to do so. IPM scouting networks and forecasting methods help us better understand pest levels. This in turn helps farmers use well-defined thresholds for making solid management decisions.
And of course, IPM works for organic and conventional farmers alike. They all know there are no silver bullets or one-size-fits-all management strategies when it comes solving disease or pest problems—which is why we need to integrate pest management strategies for the best success. Any approach to managing pests and protecting crops that minimizes health and environmental hazards by the most economical means should be thoughtfully considered and implemented.
The goal? To prevent problems in the first place. True, sometimes nature tosses us a wild card we couldn’t have guessed at. Regardless—IPM helps farmers avoid wasteful treatments while offering other options that are good both for the environment and the farmer’s bottom line.
Want to learn about IPM options for your farm? Please email me at email@example.com. And if you haven’t already, please subscribe to the weekly field crops pest report http://blogs.cornell.edu/ipmwpr/ to stay up to date on statewide scouting and management updates.
I look forward to the opportunity to work with you and wish you a safe and productive season.

by Mary M. Woodsen Comments Off on The Invasive of the Month Is … (Drum Roll)
Southeastern Pennsylvania, the epicenter of spotted lanternfly’s arrival in 2014, might seem far enough away to give us in New York prep time for dealing with this new pest, a weak flyer that usually hops to get around. But with the spotted lanternfly (Lycorma delicatula—and SLF for short), all bets are off. After all, it took over Korea, whose climate is surprisingly like our own, in no time flat. And now it’s in Maryland. Delaware. Virginia. New Jersey.
New York’s first find happened to be dead. Blind dumb luck.
A bit creepy, how cool it looks. (Photo insectimages)
How anything so pretty could be so nasty boggles the mind. But it’s the nature of nature. Since ID’ing SLF correctly is key to good IPM, let’s start with the nymphs—the young-uns. In this case they come in two snazzy colors. The early-stage nymphs are straight-on black or, once they’ve molted, black and white—handsome devils or trendy fashionistas; take your pick. For late-stage nymphs (late-stage means they molted—again—and outgrew the skin they had after they hatched), add blobs of blood-red, and that critter looks ready to conquer the world.
Which it might.
Does that bright, traffic-light red signal toxicity, as it does for many other potential prey? Right now all I know is that birds have been seen throwing up after grabbing one for a snack—and yes, they are toxic to us.
Red is ever a reminder to other critters: this might be toxic. (Photo Penn State)
Meanwhile, adult SLFs look positively benign. Lovely, in fact. Don’t believe it for a minute. These classy lads and lassies resemble butterflies or moths, but don’t believe that either—they are, you’ll recall, planthoppers; the name refers to its mode of locomotion.
Whatever. Spotted lanternflies have a destiny. Their natural expertise in the pole-vault isn’t their only way to get around. How many roads (think interstates especially) wend their way from southeastern Pennsylvania to points north, south, east and west? Lots.
Consider your car or camper, for starters. Firewood? You’d be slack-jawed at the degree to which firewood fits into the equation. Just the eggs alone—not easy to see with a cursory look—can easily hitch rides to new areas, meaning that New York is a mere hop, skip and a jump away. Trains, tractor trailers, wheel wells, the cargo hold in a jet—this pest doesn’t need to lay its eggs on organic matter. Planning a long-distance road trip? California, here we come.
“I don’t want to scare people,” says Dr. Surendra Dara, an IPM and crop advisor at the University of California, “but it has the potential to spread, and we do not have a biological-control agent.”
Which is why you, dear reader, are our eyes on the ground.
But wait. Other than toxicity, I haven’t even told you why to be alarmed about this critter. Grapes, apples, hops—these and more high-value crops rank in the billions for New York. Apples alone ring the register at about $317 million.
New York’s forestry crops are vital, too. Here’s what forest crops provide:
jobs for 49,200 people with payrolls of over $1.6 billion;
manufacturing, recreation and tourism providing over $11.0 billion to our economy;
removing greenhouse gases from the atmosphere, sequestering carbon, and producing oxygen critical for all life on earth;
filtering and buffering clean drinking water for millions of New Yorkers.
As our eyes on the ground, here’s what you need to know. Signs that spotted lanternfly are at our collective doorstep include:
sap oozing or weeping from tiny open wounds on tree trunks;
a yeasty smell (been near a brewery lately? That’s it);
inch-long, brownish-gray egg masses—like waxy mud when new, brown and scaly when old
heaps of honeydew under trees and vines and covered, often as not, with black sooty mold.
When you see this many SPFs in your orchard (this is Pennsylvania, mind you) — watch out. (Photo Smyers, Penn State)
Besides fruit and hops, what’s at risk? Everything from willows to walnuts—and smooth-barked trees especially. But keep in mind that many a mature tree which, once it has packed on the pounds around its waist and takes on a decidedly rough or furrowed look, looks svelte and clean-cut while still relatively young. Go outside and look at any gently-furrowed tree, and chances are you’re looking at a host. For those areas where tree-of-heaven runs rife, well—you’re looking at what might be its most favorite host of all.
Though it’s hard to wrap your mind around, it sups on some—maybe all—field crops. “We’ve seen it in some of the grain crops that are out there, soybean and what have you,” said Fred R. Strathmeyer Jr., Pennsylvania’s deputy secretary of agriculture. “It’s able to feed on many, many different things.”
Now think about honeydew. Not the drink, not the melon; rather the stuff bugs secrete as they feed. A case of in one end, out the other as they move down the chow line. Although native insects also secrete honeydew, the size of the SLF and staggering numbers that congregate from place to place makes for a remarkable amount of honeydew. Parked your car beneath an infested tree? Time to clean off those sticky windshield wipers.
For sure—this sticky mess and the swarms of insects it attracts gets in the way of outdoor fun. In Pennsylvania, where SLF populations are the densest, people near the heart of the problem can’t go outside without getting honeydew on their hair, clothes, and whatever they’re carrying. At which point “outdoor” and “fun” no longer have all that much in common.
So that’s it in a nutshell and, for spotted lanternfly, all the news that’s fit to print. For now.
It might not look that way from your car window, but farmland covers 23 percent of New York. It’s the foundation of New York’s multi-billion-dollar agricultural economy—one that benefits all of us, no matter where we live.
Zooming out to read the report? How easy it is to forget a severe drought after a year like 2017.
Most of that cropped land? It’s in field crops: corn, soybeans, alfalfa, and the like. (These crops sustain New York’s dairy industry, third in the nation.) Scouting all that land for pests? A job for super-heroes—or lacking that, an efficient, well-designed app.
So IPM researchers built the app. Now Extension educators with their boots on the ground and a smartphone in their pocket can note hotspots for bad little buggers. Each entry helps map trends that matter: where the pests are, when they got there, and where they’re likely to show up next.
The educators’ audience? Why, farmers, of course.
True, right now the app is mainly used by educators tracking data. But the turnaround is quick, keeping farmers in the know and New York’s farm economy healthy. Think of it as scouting on steroids. Scouting is what keeps farmers abreast of what’s happening out in the field and what they can do to prevent or minimize damage (core values of IPM!). Downloading the data farmers need, then visualizing, manipulating, and editing it—that and more, this app does it all.

by Mary M. Woodsen Comments Off on Climate, Weather, Data: Change Is the Name of the Game
Nearly two years ago, NYS IPM convened “Climate, Weather, Data,” a statewide conference focused on pests and our changing climate. Because it’s here. It’s real. So … what will a shifting climate mean for our farms and forests, our parks and gardens?
The Climate Change Garden plans and plants for the future. Photo credit E. Lamb.
We brought together researchers, crop consultants, farmers, and more from New York and the Northeast for an eye-opening glimpse into the future. One example must speak for the rest: the Climate Change Garden, housed at the Cornell Botanic Gardens, demonstrates how a range of food and nectar crops are like messengers from the future. They speak to the effects of warming oceans, drought, heavy rain, and rising temperatures on food crops, pollinator resources, and superweeds.
As if on cue, the winter of 2015-16 followed by the drought of 2016 (not to mention the rains and temperature swings of 2017) was a messenger from the future in its own right. Drought threw a monkey wrench into IPM-funded research intended to create weed forecasting models in both conventional and organic systems. Conclusions? As the researcher charitably put it, the unusual 2016 weather provided a good opportunity to look at the limiting impact of low soil moisture; with additional years of data collection, this should be a valuable year.
And take IPM research on the brown-marmorated stink bug, aka BMSB. Because of the staggering number of crops on its chow-list, and, come winter, its role as a most unwelcome houseguest in offices and homes, BMSB has plenty of people riled. But dramatic temperature swings in winter and spring (especially spring) tricked BMSB into ditching its cold hardiness too soon and falling prey to that last sudden cold snap.
We could go on, but do we need to? You get the picture. It’s a brave new world out there, and change is the name of the game.

by Mary M. Woodsen Comments Off on Planning for pollinators: No time like now
$1.15 billion. That’s what the 450 species of wild pollinators that call New York home contribute to our agricultural economy each year. But we’ve seen alarming declines in pollinators of every stripe and color. Some are bees and wasps. Others are flies and butterflies (and on the night shift, moths). Their loss is worrisome to everyone from rooftop gardeners to farmers with a thousand-plus acres in crops. These people depend on pollinators to grow the foods we eat, foods ranging from pumpkins and pears to blueberries and beans.
In fact, anyone with a garden or even planter boxes on their balcony has reason to care about pollinators. And there’s no time like the present to start planning for this year’s pollinator plantings.
This hover fly is among the hundreds of wild pollinators that contribute to NY’s ag economy—not to mention our parks and yards. (Photo courtesy D. D. O’Brien.)
IPM’s mission covers everything from farms and vineyards to backyards and parks, protecting all kinds of non-target plants and animals (even covert pollinators like tiny bees and flies ). That’s why we were invited to help out in 2015 when Governor Cuomo announced an interagency task force, led by the New York State Department of Agriculture and Markets and the Department of Environmental Conservation, to develop and promote the New York State Pollinator Protection Plan, or PPP. In fact, New York is among the first 10 states to officially adopt a PPP.
The PPP was released in 2016. And the best thing is, it’s not going to stay on the shelf. This is a living document, a roadmap of sorts to guide IPM researchers and educators, farmers and householders as they plan IPPM—Integrated Pest and Pollinator Management protocols — to keep pollinators healthy for decades to come.
We’re pleased to be aboard.

by Mary M. Woodsen Comments Off on Hops on top
Sometimes on a snowy evening there’s fine company to be had with good friends and a six-pack from your local brewery. So settle back and take a moment to savor what it took to get you there.
Hops flowers, once fully mature and used wet or properly dried, provide the distinctive taste that brewers build on to craft their beers. Photo provided.
Long ago yet close to home — the mid 19th through the early 20th centuries — New York led the world in hops production. Back then, we supplied that critical beer ingredient for breweries worldwide. But then two new and dastardly fungal diseases blew in and put an end to all that.
Now it’s déjà-vu all over again. With microbreweries and tasting rooms on the upswing, hop yards are too.
Yes, hops can be prey to the usual range of pests lurking in the soil or pathogens drifting in on the wind. But with Cornell’s IPM research there to support farmers, it’s different this time around. Today’s growers have a clear advantage that yesteryear’s famers sorely lacked — detailed production guides that cover a range of new techniques and research on biological and ecological IPM tactics unknown a century ago. Example? Flowering cover crops that not only suppress weeds but serve as a nectary to attract and retain the beneficial insects that keep pests under control.
Cosmos are an old-time favorite for gardeners, but hops growers have learned they provide nectar for minute (as in “tiny”) pirate bugs. These pirate bugs are a welcome predator of a difficult pest — the two-spotted spider mite. Photo provided.
Of course there’s more — much more — and IPM’s presence at the Cornell Lake Erie Research and Extension Laboratory contributes to careful research now published in the Cornell Integrated Hops Production Guide and available to farmers throughout New York and the Northeast. Let’s raise a glass to the growers and researchers who have made this possible.
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

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.”

PUBLISHED ON SEPTEMBER 26, 2017 | Courtesy Paul Hetzler, CCE St. Lawrence County
KEMPTVILLE, ONTARIO. — On my twice-monthly drive on Highway 416 between Prescott and Ottawa, I pass the sign for Kemptville, a town of about 3,500 which lies roughly 40 km north of the St. Lawrence. It has a rich history, and no doubt is a fine place to live, but one of these days I need to stop there to verify that Kemptville is in fact a village of surpassing tidiness. (It’s Exit 34 in case anyone wants to take some field notes and get back to me.)
Most of us would prefer not to live in totally unkempt surroundings, but Western culture may have taken sanitation a bit too far. Claims that cleanliness is next to godliness have yet to be proven by science, but research does indicate a neat, well-coiffed landscape is bad for bees and other pollinators.
Dandelions are an essential early-season flowers for our 416 species of wild bees in New York.
With all due respect to honeybees, they are seldom required to produce fruits and vegetables. Please don’t spread this around, as I do not want to tarnish their public image. But the fact is that wild bees, along with other insects and the odd vertebrate here and there, do a bang-up job pollinating our crops, provided there are enough types of wild plants (i.e., messiness) around to keep them happy for the rest of the season.
As landscapes become neater and less diverse, wild bees cannot find enough natural foods to keep them in the neighborhood for the few weeks of the year we’d like them to wallow around in our apple or cucumber flowers. In sterile, highly manipulated environments like almond groves and suburban tracts, honeybees are critical.
Dr. Scott McArt, a bee specialist at Cornell’s Dyce Laboratory for Bee Research, says there are an estimated 416 species of wild bees in New York State. When I estimate stuff, the numbers tend to be less exact, such as “more than three,” but I’ve met Dr. McArt, and I trust him on this count. Dr. McArt is quick to point out that wild critters take care of things just fine in most places. He has cataloged exactly 110 species of wild bees visiting apple blossoms in commercial orchards, and in the vast majority of NYS orchards studied, honeybees have no bearing on pollination rates. My object is not to malign honeybees, but to point out that if we learn to live with a bit more unkemptness, we will improve the health of wild bees, wildflowers, food crops, and ourselves in the process.
Dr. McArt has cataloged exactly 110 species of wild bees visiting apple blossoms in commercial orchards, and in the vast majority of NYS orchards studied, honeybees have no bearing on pollination rates. There was a presentation about it at the 2015 Pollinator Conference.
Messiness also takes pressure off managed honeybees, an increasingly fragile species, by providing them a rich source of wild, non-sprayed nectar and pollen. Orchardists do not spray insecticides when their crops are flowering because they know it will kill bees. But many fungicides, which are not intended to kill insects, are sprayed during bloom. One of the unexpected findings of research done through the Dyce Lab is that non-lethal sprays like fungicides are directly linked with the decline of both wild bees and honeybees. But banning a particular chemical is not a panacea—the situation is far more complex than that. What is needed to save bees of all stripes is a real change in mindset regarding landscape aesthetics.
This garden at Bethpage State Park Golf Course is an excellent example of entropy. Primarily established with native wildflowers, there are also a significant number of volunteers. NYS IPM staff found over 100 different species of insects, primarily bees and wasps, taking advantage of the bounty.
Increasing the entropy on one’s property is as easy as falling off a log (which of course is a literal example of increased entropy). Pollinators need plants which bloom at all different times, grow at various heights, and have a multitude of flower shapes and structures. For greater abundance and diversity of wild flowering plants, all you need to do is stop. Stop constantly mowing everything. Choose some places to mow once a year in the late fall, and others where you will mow every second third year. Stop using herbicides, both the broadleaf kind and the non-selective type.
Before you know it, elderberry and raspberry will spring up. Woody plants like dogwoods and viburnums will start to appear. Coltsfoot and dandelions, essential early-season flowers, will come back. Asters and goldenrod (which by the way do not cause allergies), highly important late-season sources of nectar and pollen, will likewise return.
Despite their unassuming flowers, Virginia creeper attracts a large number of pollinating bees and wasps. Photo: Joellen Lampman
Wild grape, virgin’s bower, Virginia creeper and wild cucumber will ramble around, without any help whatsoever. However, you may choose to help this process along by sowing perennial or self-seeding wildflowers like purple coneflower, foxglove, bee balm, mint, or lupine. Even dandelion is worth planting. You’ll not only get more wild pollinators, you’ll also see more birds. Redstarts, tanagers, orioles, hummingbirds, catbirds, waxwings and more will be attracted to such glorious neglect. No feeders required.
I strongly advocate for more chaos in the plant department, even if the local Chamber of Commerce or Tourism Board frowns upon it. Remember, just because you’re an unkempt community doesn’t mean you have to change the name of your town.
Got a sweet tooth for sweetcorn? You’re in good company. So should you hear rumors on the wind about wormy sweetcorn — or field corn or dry beans (the kind you put in your soup kettle) and you’re curious about what’s behind them, here’s the scoop:
The western bean cutworm (just call it “WBC”), a recent invasive, is making waves in the midwestern and eastern corn belts. This pest made landfall in New York’s million-plus acres of field corn in 2010, its numbers spiraling ever upward since. This year, though, has been a record-breaker. WBC has become a pest we can count on for a long time to come.
To cope with WBC, the New York State IPM Program coordinates a “pheromone trap network” for WBC in field corn; in dry beans too. A second IPM trap network focuses on sweetcorn, though it also traps for WBC in beans.
But what is a pheromone and how does the network work? Think of pheromones as scents that insects send wafting on the wind to alert others in their tribe that something important is happening — and the time to act is now. In this case, pheromones are the “come hither” perfumes female moths use to advertise for mates.
Trapped — one more male out looking for a date.
But lures imbued with chemical replicates of pheromones can intercept males on their quest, dooming them to a very different fate. IPM scouts strategically place special trap buckets around corn and bean fields. Each contains a “kill strip” treated with an insecticide. Farmers, Extension educators, and crop consultants check the buckets each week to count their take.
And though it’s their larvae — the worms — that give WBC its name, here we’re counting the adults; in this case, moths.
It’s traps — and scouts — like these that do the job.
This year the two networks combined have caught more than 35,500 moths — far more than in any other year. Those in the know, know — this is not good. WBC is a sneaky critter. It even eats its eggshells as soon as it hatches, removing evidence that it’s out and about. Meanwhile, trap network numbers can vary considerably from county to county; even from farm to farm. Regardless, when armed with counts in their area farmers know when it’s time to ramp up scouting their fields. Because once they’ve reached threshold — the IPM “do-something” point — it’s time to act.
Why wait till a field reaches threshold? Because sprays are expensive — both to the farmers’ bottom line and the environment. Because time is money too; spending it needlessly out on a rig does no favors. Because treating only at need is one very good way to keep all these costs as low as can be.
