Not Too Early to Start Planning for Pollinator Habitat

Some of our beneficial insect habitat plots looked really beautiful this fall! Others are still works in progress.

Today’s post is from our Biocontrol Specialist, Amara Dunn

Have seed and plant catalogs started arriving in your mailbox, yet? This is the time of year I start thinking wistfully about the arrival of spring. If your spring daydreams include planting habitat for pollinators and other beneficial insects, keep reading for the latest on NYS IPM’s beneficial insect habitat establishment project!

Back in October I described the purpose and design of this project. So what have we learned after the first year? First, here’s a reminder of the different treatments we were comparing. Each treatment involved either direct seeding or transplanting habitat plants, in the spring or the fall, utilizing a different method for weed control.

Treatment Fall 2017 Spring 2018 Summer 2018 Fall 2018
A Herbicide Herbicide, transplant  Weed 2x Replace dead plants
B Herbicide Till, transplant, mulch Weed 2x Replace dead plants
C Herbicide Till, direct seed Mow 3x Mow 1x
D Herbicide Till, plant buckwheat Mow 1x, till, plant buckwheat Mow 1x, transplant
E – control Herbicide Herbicide Mow 3x Mow 1x
F Herbicide Till, lay plastic Continue solarization Remove plastic, direct seed
G Herbicide Herbicide/till Herbicide 2x, till 1x Till 1x, direct seed

And here’s how much time and money we spent on each method during our first year. Each treatment was applied to a total area of 460 ft2 (0.01 A).

Treatment Supply costs

Time

(person hrs)

A – Spring transplant $417.12 13.2
B – Spring transplant and mulch $539.29 20.4
C – Spring seeding $17.75 4.4
D – Buckwheat & fall seeding $390.55 10.3
E – Control $2.32 2.6
F – Solarize & fall seeding $148.02 10.2
G – Herbicide/tillage & fall seeding $22.04 6.3

What did we get for the time and money we invested? Well, the only two treatments that looked anything like habitat for beneficial insects by October were the ones we transplanted in the spring (A and B). And of the two, treatment B looked a lot better because of the mulch we spread around the plants after transplanting to help suppress weeds. Even so, we still hand weeded this treatment (and treatment A) twice during the year. But we got much better weed control in treatment B.

Four and a half months after transplanting, the beneficial habitat plants in treatments A (left) and B (right) were mostly growing well. But there was a big difference in weed control, in spite of similar amounts of time spent weeding each treatment

Direct-seeding in the spring resulted in a few blackeyed Susans by October (and a few partridge peas slightly earlier in the year), but did not look very impressive and had a lot of weeds.

After direct-seeding in the spring and mowing four times during the summer and fall, there were a few blackeyed Susans blooming in treatment C plots.

Of the three methods we used to manage weeds during the season, alternating herbicide applications and tillage resulted in the cleanest-looking plot by October.

A few weeds were present a week after the last time the herbicide/tillage treatment (G) was rototilled. We broadcast, raked, and pressed beneficial habitat seed into these plots.

Solarizing the soil was low-maintenance once the plastic was laid in the spring. We did learn that solarization is not a good strategy if you’re trying to control purselane. It grew just fine under our clear plastic, while most other weeds didn’t. In some places, it probably reduced the efficacy of solarization because it pushed the plastic away from the soil and allowed other weeds to germinate and grow.

In some solarized plots, purslane grew happily under the plastic. Purslane was not a common weed anywhere else in the field during the season.

 

The two crops of buckwheat we grew in treatment D not only suppressed weeds, but also attracted lots of pollinators and natural enemies to its blossoms before we mowed the crop down to keep it from going to seed.

The buckwheat established quickly and crowded out many weeds. We mowed the first crop in July and re-planted. We had to mow the second crop about 3 weeks before we transplanted (not ideal).

In summary, if one of your 2019 resolutions is to plant habitat for beneficial insects, I have two pieces of advice:

  1. Spend 2019 controlling weeds. Even where we transplanted, weed pressure was a challenge, and investing in weed control before you plant is worth it!
  2. If you have sufficient funds and need or want to establish habitat quickly, transplants are the way to go. Mulch will help you with your battle against weeds.

In 2019, we’re planning to keep monitoring these plots. Check back to see how the fall-planted and direct-seeded treatments look in their second year. Most of these methods are expected to take several years to reach their full potential. We will also start counting the insects (and insect-like creatures, like spiders) we find in these plots. During 2018, we already started seeing some beneficial insects showing up in these plots, so I’m looking forward to counting them once spring finally gets here!

Here are just a few of the beneficial insects we spotted in these plots during 2018. Soldier beetles, many  hover flies, and lacewing larvae are all natural enemies of pests. We also saw lots of lady beetles and several other types of bees.

IPM Celebrates the New Year With News for You

We decided on a new look for our IPM Year in Review—our first-ever calendar. Who doesn’t put calendars to good use? I’ve already noted a couple of dentist appointments in mine.

And for you, dear reader, we offer our calendar sampler—four months, four topics, four new things to learn.

February:

It’s February and shivery cold—and time to pay careful attention to the nooks and crannies so inviting to the critters that call your home theirs. Do you hear varmints scurrying in the basement, the walls, the ceiling? Mice and kin (OK, rats) have taken up lodgings and are way overdue on the rent.

Block their access. Start with a look in the basement. For mice, the entryway need be no larger than a dime; for rats, a quarter. Take it from us: if their heads can fit through, their fat little tummies can squeeze through too. Found a hole? Found several? Get some sealant and fill ’em up.    https://conservesenecacounty.com/wp-content/uploads/2015/04/mouse.jpg

March:

Ah, March—when winter marches into spring. School kids are antsy to get outside. And us? We’ve got ticks on our mind. Here’s your blacklegged tick, up close and personal. Soon these ticks will be out and about; the health hazards can hardly be overstated.

So practice the drill—how to ID them, dress for the occasion, do tick checks. Planning a hike? Wear light-colored duds (the better to see you with, my dear), pull your socks over your cuffs—and as soon as you’re home, do tick checks. Got pets? Check them too.

Btw, though their common name is “deer tick,” many scientists prefer “blacklegged tick.” We’re speculating here—but could that be because otherwise people will get the mistaken notion they can catch Lyme from deer, which they cannot? Yes, deer are among the movers and shakers in the world of Lyme. But by the time they’ve donated their blood to the cause, mama tick will have dropped off and called it a day.

Regardless: these ticks have a lineage that goes way back. In fact, a fossilized tick was found in a chunk of amber where it dined on mammalian blood some 20 million years ago. It carried babesia—a disease that’s still in action today.

May:

It’s May now; summer is nearly here and the weeds are growing like—well, like weeds. Unperturbed by spray, horseweed and waterhemp are gaining ground, dramatically reducing crop yields. Regaining control over these herbicide-resistant weeds is a major issue for New York’s farmers.

Here’s one approach. With nearly 20 rubbery fingers on each hand and 20-plus hands, this cultivator earns its keep by dislodging, uprooting, and burying weeds while they’re still small. The boxy white contraption with two dark “eyes” and mounted at head height with a cable running toward the cab? That’s a camera, designed to move the cultivator left or right. It’s job? Keeping the cultivator aligned with the crop.

November:

Bed bugs are back, the scourge of small and big towns alike. No, they don’t spread disease. Yes, on some of us they leave itchy red welts—while others have no symptoms at all. But you don’t need to throw all your belongings away, we promise. IPM now offers to ultimate in How To guides: How to Get Bed Bugs Out of Your Belongings.

Your hair dryer and vacuum cleaner will be your steadfast companions in your battle to regain control over your mattresses, shoes, clothes, and electronics. The hair dryer’s gentle heat will flush the little buggers out of hiding; the vacuum cleaner sucks them up. The guide also provides instructions on how to quarantine your belongings long enough to starve them into oblivion. Bed bugs, even during the holidays, are manageable.

Let IPM help you!

2018’s Best of NYS IPM

“None of us is as smart as all of us.” –Ken Blanchard

2018 has been quite the year and we have been busy blogging, tweeting, videoing, and Facebooking about it. Here’s a recap of some of our more popular 2018 offerings:

ThinkIPM – our catchall blog and a great way to keep a pulse on what’s happening in New York State IPM.

Our most popular blog post was actually a guest blog by Paul Hetzler, CCE St. Lawrence County, Move Over, Medusa: Pretty? Poisonous! in the Caterpillar Clan. We’re big fans of his writing and this post on a venomous caterpillar caught a lot of your attention as well. (photo credit: Wikimedia Commons)

 

Are you safe now?

Ticks in February?

Ticks in the cold was also a popular topic. And relevant to now! Check out these two blog posts, Ticks don’t care what month it is and Ticks and the freezing weather. Hopefully they both convince you to keep up your daily tick checks.

While visiting our blog, you have also been checking out older posts. Our second most popular post viewed in 2018 was a 2014 post, Identifying Your Pest – with Poop?. There are a lot of budding scatologists out there.

Other IPM Blogs – Besides ThinkIPM, we have more dedicated blogs, and you don’t need to be a specialist to subscribe to them. Here are some of the more popular posts:

The Spotted Wing Drosophila blog has an obvious focus, but the post Spotted lanternfly found in two counties in NY captured the most views.

 

Biocontrol Bytes was begun at the end of 2018 and many of you have been enjoying the updates on the Creating habitat for beneficial insects project.

 

We saw a number of news reports about bed bugs in schools, so we wrote Bed bugs in schools aren’t going away in The ABCs of School and Childcare Pest Management blog. And you read it. We just wish the news reporters and commenters did too.

 

The 2017 NEWA Survey: IPM impact includes such gems as “93% agreed or strongly agreed that NEWA pest forecast information enhances IPM decision-making for their crops”.

 

Gypsy moths on Christmas trees? Check out the Tree Integrated Pest Management blog and see how it’s now a thing in the Gypsy Moth Caterpillars -Scout for them now post.

 

Facebook

When it comes to Facebook, video rules. Our most popular Facebook post was our claymation video, Life Cycle of the Blacklegged Tick (and Lyme Disease Prevention!). And, by the way, this claymation was part of a large Don’t Get Ticked NY campaign launched in 2018!

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.

 

Twitter

We’re not surprised that our most popular Tweet of 2018 was about spotted lanternfly. Follow us on Twitter to keep up with the latest information.

 

 

 

Annual Report

This might be cheating, because it was just released and we have no data to show its popularity, but our 2017-2018 annual report is a 2019 calendar and everyone we have shown it to has been pretty excited.

Here’s a picture of the spotted lanternfly you have been hearing about.

 

 

 

 

 

 

 

So, as we raise our glasses to 2018 and look forward to 2019, include keeping up with NYS IPM Program amongst your resolutions.

Happy New Year!

Comments Off on Pollinator Habitat

Pollinator Habitat

Today, Biocontrol Specialist Amara Dunn addresses a common question.

So you want to grow habitat for pollinators…what’s the best method?

The short answer is that there probably isn’t a single best method. But there may be a best method for you. I know it’s not a very satisfying answer, but let me explain.

Remember that an area that provides food and shelter for pollinators (and, incidentally, natural enemies of pests, too!) contains a mix of plant species that bloom throughout the growing season and variation in plant shapes, sizes, and types. Leaving debris from last year’s growth is also helpful. While there are many good reasons to use native plants, non-native plants are ok too, as long as they aren’t invasive. There are plenty of resources out there for choosing plant species for pollinators, like this list of regionally-appropriate plants, and this database that is searchable by zip code. Other databases are searchable by specific plant characteristics.

Once you’ve selected the species you want to use in your pollinator habitat area, you have two main tasks: managing weeds, and establishing the plants. And here’s where the options can start to feel daunting. How will you manage weeds – hand pulling, herbicides, tillage, a cover crop, mulch? This is a critical step in creating habitat for pollinators, and one that is too-often overlooked. Experts recommend that you plan to spend at least one full growing season focused only on this task.

The weed management strategy you choose may also depend on how you would like to establish the plants you have chosen. The two main options are planting seeds directly into the ground, or transplanting small seedlings (or “plugs”). But should you do this in the spring or the fall? In the Northeast United States, experts recommend sowing seeds in the fall. Fall is also a good time to transplant perennials. And it has the advantage of allowing you to spend the entire growing season controlling weeds. But depending on your project timeline, it may not feel like the best option for you.

To help you make informed decisions about the best way to establish habitat for pollinators, I am working with Dr. Betsy Lamb and Brian Eshenaur to measure the costs, labor, and effectiveness of different methods for establishing pollinator habitat. The work is being done in demonstration plots located at Cornell AgriTech at the New York State Agricultural Experiment Station in Geneva, NY. We are comparing six different methods, summarized below.

As you can see, we’ve included a mixture of weed management techniques (cover crop, mulch, mowing, herbicide and tillage, soil solarization) and different plant establishment techniques (seeds vs. plants, spring vs. fall timing). And we’re keeping track of the time and money spent on each method.

You can read more about the details of the methods we’re using and see pictures of our spring planting and seeding on my blog, Biocontrol Bytes. Over the next month or so, we will do our fall seeding. Stay tuned as we finish up the season and calculate inputs of time and money and analyze data collected by NYS IPM’s Bryan Brown on weed management success.

The eat-local movement: IPM works for you…

… no matter who you are.

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.

Eat local!

Comments Off on Stop the Bite – Mosquito IPM

Stop the Bite – Mosquito IPM

Lest you think we only care about ticks these days, another bloodsucker is at its prime. The hot, muggy, wet weather has created perfect conditions for buzzy, bitey mosquitoes. Besides itchy welts, they too can transmit pathogens that cause disease. And the first report of mosquitoes testing positive for West Nile Virus in NY this year was recently released.

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.

For less flippable items, such as garden ponds, Amara Dunn, NYS IPM Program biocontrol specialist, just released a new fact sheet on using Bacillus thuringiensis israelensis, or Bti for those in the know, to kill mosquito larvae.

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.

The Invasive of the Month Is … (Drum Roll)

Drum Roll: The Spotted Lanternfly

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.

Wait … now for the late breaking news:

Lanternflies Eat Everything in Sight. The U.S. Is Looking Delicious …

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, jlg23@cornell.edu (Do you work outside Cornell University and Cornell Cooperative Extension? Get in touch with Jody Gangloff-Kaufmann.)
  • educator: Lynn Braband, Rochester, 585-753-2562, lab45@cornell.edu
  • educator: Amara Dunn, Geneva, 315-787-2206, arc55@cornell.edu
  • educator: Matthew Frye, Westchester, 914-285-4633, mjf267@cornell.edu

  • educator: Brian Eshenaur, Rochester, 585-753-2561, bce1@cornell.edu

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.

Comments Off on Hops on top

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.

Contact NYSIPM educator Tim Weigle at thw4@cornell.edu for more info on this project. Learn more about hops production at  Cornell University’s School of Integrative Plant Science. Cornell also has a strong presence at the Northeast Hops Alliance.

One bug at a time: how biocontrol helps you, even in winter

Sure it’s winter. But many greenhouse growers work year-round. And what’s this about biocontrols? In fields, orchards, vineyards, and greenhouses—especially greenhouses—biocontrols are the predators and parasites that keep pests in check, minus the pesticides. What’s special about greenhouses? They’re where pests consistently find plenty of food, just-right temperatures, and little to stop them from bounding out of control. The linchpin that drives the search for alternatives to pesticides? Consumer demand.

Looks like sawdust—but it’s really bran infused with the tiny eggs or larvae of beneficial insects.

Which is where biocontrols fit in. These critters evolved to eat pests for breakfast, lunch and dinner. But there’s a learning curve involved. You can’t bring in the good guys and call it a day. Use a broad-spectrum pesticide and you’ll do them in. Which is why an Extension educator in the six-county New York Capitol District crafted a series of workshops to help growers get the hang of that seemingly simple IPM practice: biocontrol.

Since seeing is believing, growers attended a series of workshops where they saw start-to-finish biocontrol in action. What did they learn?

Examples

  • how to distribute marigolds throughout their greenhouses as a thrips (bad guy) magnet
  • how to apply a nematode drench to control the fungus gnats that eat roots
  • which 17 biocontrols can collectively cope with 21 bad guys
  • how the IPM Greenhouse Scout app helps you choose among them

Little sachets are another way greenhouse growers can introduce those tiny, good-guy bugs to the posies that need them.

As for consumer demand? People worry about pesticides on their posies. In theory, biocontrol appeals to them. But they haven’t seen it in action. If they see bugs, any bugs, good guys included—they might worry. That’s why a simple, colorful flier is part of the package, helping growers bring the message back to their base—their customers.
