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 Matt Frye Comments Off on Pest Exclusion: An Old Concept With New Life
The Scientific Coalition on Pest Exclusion, or SCOPE, started as an idea from industry expert and world-renowned rodentologist, Dr. Bobby Corrigan. Well-versed in pest management literature, Bobby’s reading of a particular sentence in Hugo Hartnak’s 1939 text, “202 Common Household Pests,” resonated with a concept he was thinking and teaching about all along, “We should have little trouble with vermin if builders would hear and understand the ‘language’ of vermin and do a better job in eliminating their entrances and hiding place.”
Indeed, Hartnak was promoting pest exclusion. But the concept never really took off, in part due to the expansion of available synthetic pesticides around the same time, which revolutionized the industry and ‘protected’ homes by directly killing pests.
Fast forward more than 60 years to the early 2000’s, when federal regulation changes and new restrictions were imposed on rodenticides, pyrethroids, and indoor use of organophosphates. These changes to chemical pest control provoke careful consideration of the long-term solutions that make sites less attractive to pests and keep them out – two essential IPM techniques of sanitation and exclusion. Sanitation removes sources of food and water that sustain pests, but requires cooperation from clients to do their part in maintaining a clean environment. On the other hand, exclusion represents an opportunity for the pest management industry to perform work on a semi-regular basis that seals openings and prevents pests from moving into and within structures.
Dr. Bobby Corrigan identifies an unprotected grate with gaps large enough for Norway rats to enter.
Traditional pest management techniques that rely on trapping or killing pests will not necessarily prevent these interactions – but exclusion can. Dr. Corrigan’s vision is to advance the pest management industry by increasing adoption of exclusion practices to limit human-pest interactions.
What building materials, structures, or design features lead to pest entry or harborage? This concrete hollow block was home to mice, as evidenced by the sebum or rub marks, and could be sealed with cement.
Together, the working groups collected data on building design, materials and other factors that might help to predict common pest exclusion issues. With an understanding of what materials fail in which situations, this can help the pest management industry in identifying common entry points, or provide insight to construction professionals for opportunities to reduce indoor pest problems. Core members also contributed to a literature review of pest exclusion (both items are still in progress). In March 2018, SCOPE members participated in a session at the 9th International IPM Symposium in Baltimore, MD to discuss different ways of promoting exclusion to enhance adoption. “Partnerships to Strengthen the Role of Exclusion in IPM” explored opportunities to include exclusion in efforts such as building renovation, weatherization, fire proofing, asthma reduction, and compliance with regulations such as the Food Safety Modernization Act and SOX compliance.
SCOPE members continue to provide training on pest exclusion techniques as a way to promote this critical and effective IPM strategy. The website includes articles from trade magazines and resources such as inspection forms to help individuals11 or companies develop their exclusion program.

by Joellen Lampman Comments Off on Stop the Bite – Mosquito IPM
Seasonal items will fill with water and provide mosquito breeding habitat.
So, with all the rain, it’s time for a quick yard inspection. When I conducted mine, it was too easy to find collected rainwater. The wheelbarrow was left right-side up. A snow rake tucked behind the shed was filled with water. An upside down garbage can collected water in its grooves. For these items, I simply flipped them over and the mosquito problem was solved. This simplest of IPM method is highlighted in the video, Managing Mosquito Breeding Sites, by Dr. Matt Frye.
These mosquito larvae are thriving in a driveway puddle – at least until the puddle evaporates.
Keeping an eye on the weather can also help with management decisions. Take, for example, the puddles formed in my driveway. Getting into inspection position (head down, butt up), it was easy to see the wriggling larvae. I checked the weather, saw it was going to be dry through the next day, and made the decision to let the puddle dry up. When I checked the driveway the next day, the puddle, and the mosquito larvae, were gone.
Alas, the rainy forecast will cause it to refill with water, again providing a good location for female mosquitoes to lay her eggs. Next step? Fill in the low spots in the driveway with sand to prevent standing water.
This dried puddle is no longer able to support mosquito larvae.
Diligence in monitoring is the key to preventing mosquitoes from breeding on your property. Monitor regularly and take steps to prevent standing water from becoming mosquito breeding sites.
You’ve all heard about them, right? Yeah, the little buggers sneak up on you, bite you, and—maybe—make you sick. Sometimes really sick.
They’re not really bugs, of course, but tiny eight-legged critters remotely related to spiders but without the benefits spiders provide. (Note that adult females plump up like small grapes once they’ve satisfied their appetite.)
Just for fun, I wrote a sentence on my finger — period and all. And yep, the larvae are that small. (Courtesy Cal Dept Public Health)
For today, we’re considering blacklegged ticks, aka the deer tick—the name it was christened with years ago, before entomologists realized that tick is already here; has been for thousands of years—and it already has a name. Yes, we’ve got a couple of other ticks we can’t ignore. But that’s for another day.
So … the best reason for ditching the name “deer tick”? It suggests deer are the problem. OK, blacklegged ticks do infest deer and deer can travel widely, so yes, they carry them around in the literal sense and ticks will drop off here, there, most anywhere. But no, deer don’t vector (aka “carry”) Lyme disease. Look to mice, chipmunks, and shrews for that.
So. Back to the topic at hand. The youngest ticks are six-legged larvae, the size of the period at the end of this sentence—and with one exception, they don’t vector disease. (More on that in another post.) After they feed on, say, a mouse or robin, they morph into nymphs and grow as large as poppy seeds. Since poppy seeds with legs are still darn small, they’re the ones that most often nail us.
And the adults? They’re more likely to vector Lyme and the co-infections that too often accompany it or act in its stead. After all, ticks have adapted to be secretive; to keep from being detected. But since by now they’re the size of sesame seeds—still small, yes, but easier to see—you’re more likely to get shed of them before they do damage.
No matter which life stage they’re at, know how to protect yourself. Because you can’t count on feeling them crawling on you. Here’s the countdown:
Tick habitat—it’s everywhere.
Recognize and avoid tick habitat. Tick species differ in where they prefer to hang out, but it’s possible to come too close for comfort to a tick anytime you leave the pavement. Sure, some parts of the state are home to orders of magnitude more ticks than others are, but that’s no reason to think you’re immune to those nasty little critters catching you unawares. And it’s so easy to be unaware.
Daily Tick Check! Regardless how careful you are, you won’t manage to steer clear of ticks 100 percent of the time. Perform daily tick checks even if you haven’t been outdoors in a day or so. Get to know the spots and bumps on your skin so you can recognize new ones. New ones that just happen to have legs.
Dress the part. If you’ll be in tick habitat (meaning you step off the pavement), take precautions by wearing light-colored, long pants tucked into your socks and a light-colored shirt tucked into pants. It’ll be easier to see ticks crawling on you and more difficult for ticks to get to your skin.
Get yourself some super-pointy tweezers, the type that airport security would probably confiscate. Be firm: steady and straight up until that sucker lets go.
Remove ticks safely. Only one method has been officially evaluated for its ability to safely remove ticks — using sharp tweezers, grab a tick as close to the skin as possible and gently pull up. Other methods could increase the risk of acquiring a tick-borne disease. To learn more, see “It’s tick season. Put away the matches.”
Which is all we’ll say for now, other than on August 7 we’re hosting a statewide conference on—you guessed it—ticks. Oh … and skeeters, too:

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 firstname.lastname@example.org. 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 Matt Frye Comments Off on What can I spray for …
Nobody—not even an entomologist like me—wants to see critters in their home, office, school, or favorite restaurant. But see them we do. And unfortunately, the first reaction most people have is to reach for a can of bug spray and hose the place down.
But what does this really accomplish? Two things: a quick kill of only the critters you sprayed, and you’ve now left a coating of pesticides wherever you sprayed. Satisfied? Probably not, since your goal is to solve the problem, not just kill a few critters. If so, then put down the bug spray and walk away—slowly.
When we think of pests, we might imagine them as vile creatures that are intentionally tormenting us. The truth, however, is that pests are always there for a reason. Maybe they are inside because they found a gap leading to a safe place to spend the winter (think brown marmorated stink bug, ladybug, or boxelder bug). Or maybe your gutters are clogged and there is a moisture problem inviting to carpenter ants. Or you have overripe bananas with the stem torn at the top, exposing the fruit within, and now you see fruit flies. While it’s true that a spray might kill pests—so too can a swift shoe.
But if we want to develop a solution that addresses the issue and prevents future problems, we must follow two simple steps:
Inspection. Where are the pests found and how did they get there? It might feel like your whole house is infested, but with a thorough inspection you can often find the source of a problem by looking for where the critters or their evidence are most numerous. If you can find the source of where they are feeding or breeding, chances are you can do them in.
Identification. Knowing the identity of a pest tells you why it is there. It’s also a necessity for crafting a sound management plan. For example, this spring I received many calls about ants. Even when callers had tried sprays, they were ineffective. Why? Each pest is there for a different reason—and needs its own management approach.
Carpenter ants trailing on the outside of a building might be moving from outdoor parent nests to indoor satellite nests.
Case 1: Ants in Rental Home! Using a few pictures to determine size and the number of nodes, the ants were identified as carpenter ants, which do not actually eat wood. Instead, they excavate rotten wood to make their nests. This means carpenter ants indicate a moisture problem somewhere in the structure; an important problem you might not otherwise have known about. So in an oddball way, you owe them a debt of gratitude. And although parent nests are typically outdoors, satellite nests can be found inside buildings—so an inspection is needed to discover where the ants are living. This can be accomplished by baiting and tracking ants to the source, then eliminating the rotten wood and ant nest. For more details, see our carpenter ant fact sheet.
Case 2: Ants in Bathroom! These ants are identified by how they smell when crushed. Their name? The odorous house ant (abbreviated OHA). They build nests in moist locations and forage indoors for spilled foods.
Odorous house ants can move their entire colony or split into several colonies — making it tough to deal with them. (Credit: Janet Hurley)
Based on their biology, OHA can be difficult to manage because the colony is mobile—moving nest locations at will—and can actually split into multiple colonies if sprayed or for other reasons. To date, the best method to control OHA are certain baits that, when placed correctly, can be spread throughout the colony to achieve control.
Case 3: Winged Ants Indoors! Known as citronella ants by their smell, this species isn’t really a pest of homes because they don’t eat what we eat, nor are they at home indoors. Instead they live in the soil and feed on secretions from root-feeding insects. But they can be a nuisance when winged ants emerge into homes. Since their sole purpose in life is finding a new place to live, spraying or baiting are pointless. To avoid problems down the line, you’ll need to eliminate the cracks and crevices where ants are getting inside.
Foraging pavement ants bring bait back to the nest and spread throughout the colony. They’re a great target for baits.
After you’ve found where the pests really are and ID’d them correctly, you can a develop short-term plan to reduce their numbers and long-term solutions that fix the conditions that allowed or enticed them in in the first place.
Need help identifying a pest? Here are some options:
… and now, more than ever, poison ivy’s gonna make you itch. (The Rolling Stones)
I remember the first time I had poison ivy. The particulars are long lost along memory lane. Even so, it was unforgettable. Most likely I was about five years old and, as a born and bred tomboy, I’d been scrambling around in the woods. From that point forward I knew exactly what poison ivy looked like. Sometimes it’s shrubby or low to the ground. Other times its hairy, ropelike vines, thicker than my wrists, twine their way up trees like ropes on the masts of tall sailing ships of yore—or so I imagine them. And yes, the vines are poisonous too.
“Leaves of three, let it be.” Of course there’s more to ID’ing poison ivy. Read on. (Photo Massachusetts Audubon)
Only once since have I gotten poison ivy—not a bad case, either. I was, after all, dressed for the occasion. I was hunting it down, one tangled root after the next, from the woods behind a friend’s daycare home. Toddlers, as we all can appreciate, are simply too young to learn the perils of poison ivy. I hauled it out of there by the bushelful. Funny that after all these years I’ve no clue what I did with it.
Burn it I did not, that’s for sure. I have the merest sketch of a memory—my mom telling me how she’d breathed the smoke from a burning heap of the stuff. Nasty. Can make you really (really) sick—a serious occupational hazard of forest-firefighters.
But these days poison ivy isn’t just a hassle for woodsy sorts who live well past the edges of nearby villages and towns. It’s getting worse for everyone, though some more than others. Why? Let’s fast-forward to the here and now. To a relative here-and-now; the research I’m citing was published in 2006 in PNAS (the Proceedings of the National Academy of Sciences). Research that, btw, has yet to lose its gloss. News stories as recent as 2015(The New York Times) cite that study in noting the likely consequences of an inadvertent brush with the stuff—especially if you live in a big city. Sure, urban dwellers always had to cope with this wicked vine too. But now they have lots more to worry about than country folk do.
More CO2 in the air is like putting poison ivy on steroids. (Image Climate Central)
Why? Lewis Ziska, one of the lead scientists on the six-year study in a forest at Duke University, found that with increased atmospheric CO2 we get bigger, stronger, leafier poison ivy. Poison ivy that can be way more potent in large cities. Here’s how it works:
Mega-cities are proxies for the planet. They have as much carbon dioxide in their air as the rest of the planet will have in 50 years or so. And CO2 is plant food. Like so many other plants, especially weeds (more on that some other day), poison ivy responds by piling on the pounds, as it were—and producing more urushiol.
If it’s climbing up your apartment building, what better reason could you have than learning to ID poison ivy? (Photo poison-ivy.org)
Haven’t heard of urushiol? It’s the toxic oil that causes that nasty rash. Ziska confirmed those findings in a follow-up study in growth chambers. His calculations, he told Climate Central, are based on the CO2 levels at the National Oceanic and Atmospheric Research Administration (aka NOAA) Mauna Loa research station in Hawaii. What did the research tell him? CO2 concentrations on the ground, where poison ivy actually grows, are usually about 10 percent higher than they were in 1950—not long before my first encounter with poison ivy. And in urban areas they can be up to 30 percent higher.
Thirty percent. Take a moment to absorb that.
Not only that, but from parks to vacant lots, cities mimic the fragmented forests you see wherever a suburb has muscled its way into the landscape. And poison ivy likes fragmented landscapes. It also likes—well, what doesn’t it like? Poison ivy can grow in swampy forest edges and concrete rubble; along fences; in parks or on school grounds; or up and around homes and apartment buildings. So wherever you are, learn to ID poison ivy. “Leaves of three, let it be” is where you start. But some harmless plants also have clusters of three leaves. After all, the numero-uno IPM mantra for any environmental issue is prevention. And prevention is based on having a solid ID.
Curious? Want to check it out? Not! Just walk on by. (Photo TownVibe Wilton)
But surely you’re safe during winter? If only. Unlike many other weeds, which die back when the weather turns cold, the urushiol in poison ivy will get you regardless of the weather. Beware of leafless vines. This is not the time to try and yank them off your trees. If the toxin gets on your gloves or coveralls, it can get on you.
I could say so much more about no end of things related to poison ivy or rising CO2 (or both) … including (for instance) sleek vs. long-haired dogs and cats or the food choices of goats, muskrats and deer. But I have to stop somewhere. And that somewhere? It’s here.

by Mary M. Woodsen Comments Off on Pests, Pesticides and Proposals: Funding IPM Community Projects
Pests and pesticides—both can pose problems to our health, our environment, and our economy. At the New York State Integrated Pest Management Program (NYS IPM), we help New Yorkers address those problems safely and thoughtfully. How? Through innovative biological, cultural, technological, and educational practices. IPM, in a word.
Community IPM takes place in settings as varied as school buildings and grounds; residential and office buildings; gardens, parks and landscapes; and golf courses and right-of-ways. Now we invite grant proposals from qualified New Yorkers who want to develop, evaluate, or demonstrate feasible IPM methods. Budgets must not exceed $8,500. Our deadline: April 6, 2018. Funds must be spent by February 28, 2019.
The German cockroach needs no introduction. If it can get on your fork, it can get in your food. Credit Clemson University, USDA.
All projects must accomplish one or more of the following:
develop, advance, test or refine new IPM strategies;
demonstrate a link between IPM practices and reduced risk to human health or pesticide residues;
measure the positive change or potential impact of IPM practices or adoption, or survey current IPM knowledge;
develop Community IPM resources, such as brochures, websites, fact sheets, manuals, and apps for smartphones and tablets;
develop IPM educational programs, such as workshops or curriculum;
educate others about IPM through outreach and demonstrations.
Audiences could include school administrators, teachers and students; landscape and structural pest management professionals; vector control specialists; municipal employees; nuisance wildlife control operators; golf course personnel; arborists; right-of-way managers; day care operators—just about anyone, in fact. We encourage projects that reach new audiences or develop new partnerships.
Two years. Yup. Ticks know how to make good use of their time.
Our Community IPM priorities include: develop or demonstrate solid strategies for dealing with rodents or cockroaches; develop, confirm or promote methods to lessen the impact of ticks; research, demonstrate or create outreach projects that promote pollinator health and conservation; and research and demonstrate alternatives to imidacloprid on lawns and athletic fields.
Yes, there are plenty more. But for 2018, these four are our greatest needs.
Got Questions? We encourage you to discuss your ideas with NYS IPM community staff, including:
coordinator: Jody Gangloff-Kaufmann, Long Island, 631-539-8680, email@example.com (Do you work outside Cornell University and Cornell Cooperative Extension? Get in touch with Jody Gangloff-Kaufmann.)
coordinator: Elizabeth Lamb, Ithaca, 607-254-8800, firstname.lastname@example.org
educator: Brian Eshenaur, Rochester, 585-753-2561, email@example.com
And consider: the most common critiques of past proposals have been that the budget lacked in clarity, explanation or justification—and those seeking grants didn’t discuss projects ahead of time with IPM staff.

by Mary M. Woodsen Comments Off on So many acres, so little time: IPM’s answer to where the pests are
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 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.
