Thursday September 26th was the Planting for Beneficial Habitat Twilight meeting. Attendees learned how habitat for pollinators and other beneficial insects show good stewardship of the land. Dr. Dunn explained several methods of establishment, the benefits of hosting pollinators and other beneficial insects, and their impact as biological control.
Dr. Amara Dunn speaks with Cooperative Extension visitors.

Wild parsnip sap can cause painful, localized burning and blistering of the skin. – New York State Department of of Environmental Conservation
Wild parsnip going to seed. The sap in this widely spreading invasive plant can cause severe burns.
A few weeks ago we discussed the invasive wild parsnip as a hidden danger for weekend weedwackers. Now it is much more obvious with its bright yellow flowers, but if you are looking to control it now, straight mowing is off the table. Some of the heads are going to seed and mowing will simply distribute those seeds, ensuring a new crop of wild parsnip next year.
Whether you choose to dig out the root, cut the root an inch or two below the soil, or mow, first cut the seed head off with clippers and put it in a plastic bag. The bag can then be left in the sun to rot the seeds before disposal. And don’t forget to wear protective clothing to prevent any sap from reaching exposed skin or eyes.
Use a boot brush to clean mud and seeds off your boots. Remember to check the tread!
This is also the time of year when seeds of this and other invasive species can be accidentally transported by hikers and dog walkers. Avoid brushing against plants. Check shoes, clothing, and gear after leaving an area. Remove any seeds that are found and seal them in a plastic bag. (This can double as a tick check!)
For more information on preventing the spread of invasive species while hiking, biking, camping, and, well, any outdoor play, a great resource is PlayCleanGo. And consider taking their pledge to Stop Invasive Species in Your Tracks.
Let’s stay safe out there!

by Joellen Lampman Comments Off on Don’t Make Your Own Tick Tubes
“Frugality, I’ve learned, has its own cost, one that sometimes lasts forever.” – Nicholas Sparks
Commercially available “tick tubes” are tubes filled with permethrin-infused cotton. Mice take the cotton to line their nests and are treated for ticks every time they return home. It’s estimated that a typical ¼ acre yard needs six tubes twice a year, with a 12 pack costing ~$45 . Although this cost isn’t excessive, there are many videos and articles on making DIY tick tubes to help people save money. But what is the actual cost?
A dozen tubes covers about a 1/4 acre for $45.
3 Reasons Why Making Your Own Tick Tubes is a Bad Idea:
1) They probably won’t work.
A pesticide product contains inert ingredients that help the active ingredient (in this case, permethrin) perform properly for the uses listed on the product label. The formulation used in commercially available tick tubes is uniquely suited for controlling ticks on mice. Other permethrin formulations are designed for other uses which are specifically listed on the label.
2) You could be putting yourself, others, pets, nontarget animals, and the environment at unacceptable risk.
Tick tubes target ticks attached to field mice. When spending time in the nest, mice expose themselves to the tick-killing products.
The EPA will register the use of a pesticide only if rigorous safety testing shows it will “pose no unreasonable risks to people or the environment when used according to label directions.” Only those uses listed on a pesticide label have met this standard, and making your own tick tubes is NOT a use listed on the label of any permethrin product. One potential risk: Permethrin is highly toxic to bees. Bumble bees often nest in abandoned mouse burrows, so making your own tick tubes could harm these important wild pollinators.
3) It is against the law.
Because of Reason #2, the first sentence in the Directions for Use section of all permethrin products is “It is a violation of federal law to use this product in a manner inconsistent with its labeling.” Which, by the way, also means it is against your state’s laws.
Commercially available tick tubes cost more because it takes time and money to develop the right mix of ingredients and conduct the required safety testing to ensure that the product will control ticks without putting people, pollinators, and the environment at risk. DIY tick tubes that pose greater risks while providing poorer control of ticks are hardly a bargain; be sure to use the real thing.
Girl scouts troop 40001 in Trumansburg, NY is working on their Bronze Award, which involves planning and establishing a pollinator-friendly community garden for raising awareness about the importance of pollinators in agriculture, our landscape, and community. The girls have spent nearly 20 hours preparing for their garden, including researching the best flowers to grow, planning the layout of the garden, learning about the more than 500 species of pollinators in NY, planting seeds of many perennial flowers that benefit pollinators, and writing letters to community leaders requesting a site for the garden to raise awareness in the community.
On Earth Day, Dr. Betsy Lamb of the NYS Integrated Pest Management Program was invited to share her horticultural expertise and passion for pollinators with the girl scouts. Dr. Lamb shared examples of the many bees, flies, butterflies, moths, bats and hummingbirds who pollinate our native, ornamental and agricultural crops in NY. The girls learned how bees see in the ultraviolet spectrum and that many flowers are specifically designed with their particular pollinators in mind to maximize reproduction. Dr. Lamb provided many samples of fresh flowers for the girls to dissect and to learn about flower anatomy and biology as it pertains to the various methods of pollination, which was a big hit with the girls! She also gave some tips on garden establishment to ensure success.
The girls shared their plans for the garden with Dr. Lamb, who was impressed by the knowledge of the girls and the wide range of beneficial blooms they had selected to plant. The garden will include 13 different types of flowers, selected with different bloom types and flowering times to feed and support pollinators from spring to fall, along with an informational sign on the benefits of pollinators and beneficial insects to our community. The garden will be established this summer for the Trumansburg community to enjoy for years to come. This sort of hands-on learning, fostered by Dr. Lamb, will not soon be forgotten by these girl scouts!

by Joellen Lampman Comments Off on Happy National Weed Appreciation Day!
It really boils down to this: that all life is interrelated. We are all caught in an inescapable network of mutuality, tied into a single garment of destiny. Whatever affects one destiny, affects all indirectly. – Dr. Martin Luther King, Jr.
Ahhh, the weed. Despised by many, almost to the point of violence. Once, while waiting for my older child to get out of preschool, I sat in the lawn and blew dandelion heads to the delight of my infant. I’ve never forgotten the sudden manifestation of a red-faced man screaming at me about terrorizing the neighborhood. (I like to think my son was unaffected.)
The first step in IPM is determining if you have a problem. All those years ago, a large, angry man was a problem, but I contend to this day that the dandelions were not. An unknown author penned that weeds are people’s idea, not nature’s. And many through the years have found inspiration from weeds. While researching this post, I had the option of strictly sticking to quotes about weeds (don’t worry, I didn’t), but I will add a few. There are quotes about their survivability:
You can’t help but admire a plant that has adapted to lawn mowers.
A weed is a plant that has mastered every survival skill except for learning how to grow in rows. – Doug Larson
A fresh and vigorous weed, always renewed and renewing, it will cut its wondrous way through rubbish and rubble. – William Jay Smith
Quotes about weeding:
Plant and your spouse plants with you; weed and you weed alone. – Jean-Jacques Rousseau
And many waxed poetic about their hidden value:
What is a weed? A plant whose virtues have never been discovered. – Ralph Waldo Emerson
When life is not coming up roses, Look to the weeds and find the beauty hidden within them. – F. Young
But beyond their value as a philosophical aid, can weeds be beneficial?
In fact, what weeds you find can tell you something about the soil. Is it wet or dry? Lean or fertile? Compacted? Acidic, alkaline, or neutral? Check out the short overview from the University of Vermont, What Weeds Can Tell You. Then act accordingly.
Often, weeds we find troublesome are plants we once valued. Dandelions, garlic mustard, plantain, and burdock are examples of plants brought over and cultivated by settlers to North America for food and medicine. And there are efforts to regain that value. One doesn’t need to spend too much time on the internet to find many resources on edible weeds. Take a look at this short video, Edible Weeds | From the Ground Up, developed by the University of Wyoming Extension (which includes some precautions you should take if you want to try eating your problems away). The Northeast Sustainable Agriculture Research and Education recently funded a project looking at bringing edible weeds from the farm to the market.
These trichogramma wasp parasitized European corn borer eggs aren’t going to hatch.
There is research looking at the ecosystem services provided by weeds in agricultural settings. In their project, Integrating Insect, Resistance, and Floral Resource Management in Weed Control Decision-Making, Cornell researchers make the argument that while weeds can compete with crops, they can also benefit the entire system. They use milkweed along a field of corn as a case study. There are aphids that feed on the milkweed and produce honeydew, which benefits beneficial insects such as wasps that lay their eggs in the eggs of insect pests such as European corn borer. And that’s before they discuss the benefit to monarch butterflies.
Early flowering weeds, such as this purple deadnettle, provide an early spring food source for pollinators.
And speaking of butterflies… and bees… and other pollinators, in the write-up of a study looking at the capacity of untreated home lawns to provide pollination opportunities, they reclassified weeds as “spontaneous lawn flowers”. So much friendlier! By the way, they found 63 plant species in those lawns. In a parallel study looking at mowing and pollinators, they found that lazy lawn mowing led to more spontaneous lawn flowers leading to more pollinators. So now I have also given you an excuse to mow less. You’re welcome.
Winter weather doesn’t mean time to stop thinking about ticks. Certainly not for the Don’t Get Ticked New York team here at the NYSIPM program. Tick are active year round, and are out looking for hosts We’ve continued to provide resources and give talks around the state, and update our own resources. Visit the Don’t Get Ticked New York page.

by Debra E. Marvin Comments Off on 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.
Replace dead plants
Till, transplant, mulch
Replace dead plants
Till, direct seed
Till, plant buckwheat
Mow 1x, till, plant buckwheat
Mow 1x, transplant
E – control
Till, lay plastic
Remove plastic, direct seed
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).
A – Spring transplant
B – Spring transplant and mulch
C – Spring seeding
D – Buckwheat & fall seeding
E – Control
F – Solarize & fall seeding
G – Herbicide/tillage & fall seeding
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:
Spend 2019 controlling weeds. Even where we transplanted, weed pressure was a challenge, and investing in weed control before you plant is worth it!
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.

Here’s the latest on Spotted Lanternfly from Ryan Parker, Extension Aide at NYSIPM.
Adult Spotted Lanternfly, Photo Tim Weigle, NYSIPM
Concern over the invasive and destructive spotted lanternfly (Lycorma delicatula) (SLF) generated many online resources by states researching new and active populations. Thought to have arrived in Berks County, PA, in 2012, this showy planthopper attacks more than seventy species of plants in the United States. New York State’s primary concern is outreach, monitoring, and proactively approving 2ee pesticide labels for control. Because live adults and nymphs (and egg masses) hitchhike from states with known populations, New York State has an external quarantine.
An external quarantine is a restriction of specific items that facilitate ‘hitchhiking’. In other words, if you’re traveling back from a state with an established population consider that your utility trailer, bicycle, tent canopy, or that swing set you bought in a yard sale might have SLF adults, nymphs, and egg masses tagging along. Any item that has been outside for a while needs to be checked before it crosses the border. Here’s the full list, downloadable, printable.
Download, print and share to reduce the spread of Spotted Lanternfly
In an attempt to educate the public and limit the spread of this pest, New York State Integrated Pest Management (NYSIPM) has teamed up with New York State Department of Environmental Conservation (NYSDEC), United States Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS), and New York State Agriculture and Markets (NYSDAM) to create the New York State Spotted Lanternfly Incident Command System (NYS SLF ICS).
Currently, NYSIPM’s primary SLF focus is outreach. We’ve created materials that help identify, monitor, and manage this pest. Along with the public departments listed above, we continue to remind NY residents how to report findings (firstname.lastname@example.org) and we provide educational materials LIKE OUR NEW WEBPAGE. Besides our many resources (Powerpoint presentations, Spark videos, posters, photos and much more), and links to other state or government agency information, you’ll find a regularly updated incidence map showing county-by-county news of SLF sightings and populations across the Northeast and mid-Atlantic regions.
Coming soon, two Moodle courses from NYSIPM and our Cornell CALS collaborators. One course provides general knowledge about SLF, while the other focuses on Tree of Heaven (Alianthus altissima), one of SLF’s preferred hosts. Both offer pesticide applicator credits.
