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!

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.
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:
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.
So far, the few New York state sightings of SPOTTED LANTERNFLY, a highly invasive and potentially devastating invasive insect, have been linked to their propensity to hitchhike from the quarantined areas in Pennsylvania, Maryland, Delaware and Virginia.
These discoveries have been adults thought to have traveled on vehicles or shipping materials and resulted in a quick and thorough survey of the area to locate and destroy any chance of additional insects.
This time of year, gravid adult females have probably finished laying eggs and covering them. They aren’t that fussy–they will lay eggs on any inflexible object (preferably tree bark) but it could be your vehicle, utility trailer, firewood, and more.
The responsibility to reduce the chance of infestation in New York state also lies with travelers and shippers. While the DEC does do periodic spot checking along major federal roadways, short of placing a guard station at every entry point, this means a lot of potential influx of this pest. Share the information, learn to recognize these pests and, yes, check for hitchhikers in the form of adults, nymphs and egg masses.
Once the egg mass covering has dried down from white to dull gray or grayish brown, it becomes highly camouflaged on certain surfaces like bark where its cracking mimics the surface.
Ask your friends and relatives coming in for the holidays if they are aware of this pest and refer to the many online sources:
We at the NYSIPM program are always informed and entertained by the writings of CCE St. Lawrence’s Paul Hetzler. We couldn’t pass this one up!
Even Santa Claus himself cannot grant a wish for a white Christmas—it is a coin toss whether the holiday will be snow-covered or green this year. A verdant landscape is not our Christmas ideal, but we can keep more greenbacks in the hands of local people, and keep our Christmas trees and other accents fresh and green for longer, when we buy local trees and wreaths.
Not only are Christmas trees a renewable resource, they boost the regional economy. Even if you don’t have the time to cut your own at a tree farm, do yourself a favor this year and purchase a natural tree from a local vendor. She or he can help you choose the best kind for your preference, and also let you know how fresh they are. Some trees at large retail outlets are cut weeks, if not months, before they show up at stores.
There is an additional reason to buy local in 2018: The NYS Department of Agriculture and Markets has announced a quarantine on out-of-state Christmas trees to prevent the spread of a devastating new insect pest. The spotted lanternfly (SLF) is a major pest of many tree species, as well as grapes and various other crops, but it is especially fond of sugar maples. First discovered in Pennsylvania in 2014, this tree-killing Asian bug has since spread into New Jersey, Delaware, and Virginia. SLF females lay their camouflaged eggs on almost anything, and in 2017, egg masses were found on Christmas trees grown in New Jersey, prompting the quarantine.
Of all the memorable aromas of the holiday season, nothing evokes its spirit quite like the smell of a fresh-cut pine, spruce or fir tree, wreath or garland. Although the majority of American households where Christmas is observed have switched to artificial trees, about ten million families still bring home a real tree.
Every type of conifer has its own blend of sweet-smelling terpenols and esters that account for their “piney woods” perfume. Some people prefer the fragrance of a particular tree species, possibly one they had as a child. A natural Christmas tree is, among other things, a giant holiday potpourri. No chemistry lab can make a plastic tree smell like fresh pine, fir or spruce.

The origins of the Christmas tree are unclear, but evergreen trees, wreaths, and boughs were used by a number of ancient peoples, including the Egyptians, to symbolize eternal life. In sixteenth-century Germany, Martin Luther apparently helped kindle (so to speak) the custom of the indoor Christmas tree by bringing an evergreen into his house and decorating it with candles. For centuries afterward, Christmas trees were always brought into homes on 24 December, and not removed until after the Christian feast of Epiphany on 6 January.
In terms of crowd favorites, the firs—Douglas, balsam, and Fraser—are very popular, very aromatic evergreens. Grand and concolor fir smell great too. When kept in water, firs all have excellent needle retention. Pines also keep their needles well. While our native white pine is more fragrant than Scots (not Scotch; that’s for Santa) pine, the latter far outsells the former, possibly because the sturdy Scots can bear quite a load of decorations without its branches drooping. Not only do spruces have stout branches, they tend to have a strongly pyramidal shape. Spruces may not be quite as fragrant as firs or pines, but they’re great options for those who like short-needle trees.
The annual pilgrimage to choose a real tree together has been for many families, mine included, a cherished holiday tradition, a time to bond. You know, the customary thermos of hot chocolate; the ritual of the kids losing at least one mitten, and the time-honored squabble—I mean discussion—about which tree to cut. Good smells, and good memories.
For the best fragrance and needle retention, cut a one- to 2-inch “cookie” from the base before placing your tree in the stand, and fill the reservoir every two days. Research indicates products claiming to extend needle life don’t really work, so save your money. LED lights don’t dry out needles as much as the old style did, and are easier on your electric bill too.

Educator bee-guiles audiences with enthusiasm and results, earns Excellence in IPM award
A 13 year veteran of Putnam County, Lerner’s work as an invasive species educator, native plant and pollinator advocate, and turfgrass researcher has demonstrated her commitment, enthusiasm and mastery of IPM tools and tactics. Promoting IPM through education, demonstrations, and inclusive programs, Lerner has empowered her community with effective, science-based techniques.
“Jennifer Lerner’s willingness and enthusiasm for extending information to her region is legendary,” says Elizabeth Lamb, IPM Ornamentals coordinator. “She’s a gem.”
As a coordinator and collaborator for the Hudson Valley portion of the multi-year, multi-state project on keeping weeds out of sports fields on a budget, Lerner and her Turfgrass Team volunteers used “repetitive seeding” on high-use sports areas. The result? Safe playing surfaces that filled back in game after game. Why does it matter? Because we’d rather use seed than herbicides—and weeds make for slick footing and, too often, expensive falls.
Lerner also made Putnam County a leader in lily leaf beetle research. Notorious for decimating lilies, this pest is a pain for nurseries and householders alike. Enter an IPM management option: the release of a parasitoid wasp that feeds on the beetle larvae. Lerner secured a plot of land for the project, trained volunteers on the life cycle and proper handling of the wasps, and organized their successful release. Lerner’s most crucial contribution? Her outreach and clear communication skills, says project manager Brian Eshenaur.
A stalwart champion of bees and the native plants they depend on, Lerner so inspired the students from her advanced pollinators classes that they took what they learned and passed it on to over 530 community members at farmer’s markets and county fairs. And she created a special section—“Beauty and the Bees”—at the Master Gardeners’ annual plant sale. This section, now three years old, dwarfs the inventory of non-natives plants offered for sale.
There’s more, of course. Lerner also managed a demonstration pollinator garden located beside the Putnam County Department of Motor Vehicles, which attracts hundreds of patrons day in and out.
“Jen has been an important influence in promoting native plants,” says Master Gardener Janis Butler. “Whether it’s through engaging lectures, newsletter articles or in-person demonstrations, she illustrates the importance of planting natives wherever possible.”
Lerner received her award on November 14 at Cornell Cooperative Extension’s yearly in-service training in Ithaca, NY.
Press Release written by NYS IPM Science Writer Mary Woodsen
Today’s post is from Matt Frye. FYI: (He didn’t just show up on our door talking ticks or rats! And we’re glad he escaped the vines to join our program.)
Kudzu is an invasive vine that was introduced from Japan to the United States in 1876. In its heyday, kudzu was planted extensively throughout the southeastern US, where it was touted for its ability to prevent soil erosion on embankments, restore soil nitrogen (it’s a legume), and provide high quality forage for livestock. Unfortunately, like many invasive organisms introduced outside of their native range, kudzu became a pest species due to its rapid growth rate and the ability to shade out existing vegetation.
Kudzu was planted extensively on slopes for erosion control.
Based on the detrimental effects of this plant and the cost of management, kudzu is listed as a noxious weed in several states. It has also been the subject of extensive research by the US Forest Service, including my graduate research at the University of Delaware, which examined the potential for biological control of kudzu using insect natural enemies.
Kudzu vines grow up trees, over bushes, and create a dense cover of foliage that kills other plants.
In 2014 I published a slide set describing my work and experience with kudzu: why it’s a pest, some of its ecological impacts, common misconceptions, how it was grown, and how it can be killed. Since publishing this document, I have received dozens of requests for more information about the plant. What do most people want to know? How to grow it! This has been for art installations, research on allelopathy, a test to determine if kudzu can grow in zero gravity (yes, kudzu literally will be sent to space), genetic studies and for use as wildlife forage.
The last request for information to grow kudzu in New York was most alarming, and led to communication with colleagues at the New York State Department of Environmental Conservation. As it turns out – there is a regulation (6 NYCRR Part 575) that prohibits the possession, transport, importation, sale, purchase, and introduction of kudzu and other prohibited and regulated invasive species in New York (thank goodness!). And while there is a loophole for permits to be issued, these are strictly for “research, education or other approved activities.”
Can I help you to manage the plant, and offer suggestions for what to do in spaces where kudzu has been cleared? You bet! Can I help you to grow the plant for research purposes? Sure. But if your interest in growing kudzu is for non-academic purposes –I can’t help you. Sorry (not sorry).
Matt Frye is our Community IPM Extension Area Educator, housed at 3 West Main Street, Suite 112, Elmsford, NY 10523
Matt provides education and conducts research on pests that occur in and around buildings where people live, work, learn and play. The focus of Matt’s program is to help people prevent issues with pests such as rodents, bed bugs, ticks, cockroaches, and indoor flies; or to provide management recommendations for existing problems.

by Debra E. Marvin Comments Off on Spotted Lanternfly: A Foe You Should Know
Ryan Parker, NYSIPM Program/Extension Aide II, has spent plenty of hours facing Spotted Wing Drosophila. Today he’s discussing the newest spotted pest.

Tree of heaven (Ailanthus altissima) is just heavenly to a spotted lanternfly (Lycorma delicatula). This invasive planthopper is sadly all but exclusive to that invasive tree, but has been found on stone fruit, blueberries, grapevine, and a smorgasbord of 70+ species as hosts. Its ability to use favorites such as hop vines and black walnut as preferential hosts for its life cycle will continue to be studied.
Perhaps it would be more accurate to call the spotted lanternfly (SLF) by its alternate name, Chinese blistering cicada. Acting to blister, fester, spread out its cute little wings and become personified as new breed of supervillain. Black widow please step away, Hollywood + spotted lanternfly = horror-able. All puns aside, everybody loves facts.
The insect has been found in 2014 in PA (now at infestation levels), DE (2018), NJ (2018), VA (2018), and NY (2018). In New York, only one insect was found at both locations (Albany and Penn Yan). NYS citizens who were knowledgeable in the identification of the insect reported the finding, proving that awareness of this pest will play a crucial role in limiting its spread.
SLF is aesthetically pleasing. Case in point:

Looks aside, its true colors show when its presence leads to crop loss, increased maintenance, and management costs. Don’t forget the reduction of a person’s quality of life and hazardous working conditions.
These insects, with all life stages present, mass on a given plant, sucking sap through their piercing-sucking mouth parts. Unlike the earlier instars, older SLF can pierce through thicker tissue. They do not feed directly on fruit, but may affect fruit quality.

While feeding, spotted lanternflies’ honeydew excrement encourages the growth of sooty mold that builds up on leaves, fruit, and around the bases of trees–especially if infestation levels are high. The presence of a fermenting odor caused by SLF feeding damage, and the sweetness of excreted honeydew also attracts nuisance insects, including wasps and flies. And sooty mold can become slippery. There is great concern about the sheer numbers of insects, because SLF abundance can be problematic for agricultural machinery and harvested products.
Spotted lanternfly lays eggs on virtually any smooth and strong surface, including plant material, stones, bricks, metal, and plastic. Thus, egg masses can be spread easily and unknowingly, and their dispersal can occur through practically any mode of transportation.

One generation occurs per year: adults develop in July, lay eggs from September-November. Overwintering egg masses—each containing 30-50 eggs—are usually covered in a waxy brown substance resembling mud. First instar nymphs emerge between May-June. First three instars are black and white; the fourth acquiring red pigments.
There is no current lure for SLF. Sentinel trees of tree of heaven are used to monitor, trap, and kill insects with systemic insecticides. Wrapping trees trunks with sticky bands, or scraping off egg masses can help. Or simply squish the nymphs and adults.
Anyone that suspects they have found SLF is encouraged to send a photo to email@example.com. Please note the location of where the insect was found, egg masses, and/or infestation signs. Department of Environmental Conservation (DEC) and Dept. of Ag and Markets (DAM) also encourage the public to inspect outdoor items such as vehicles, furniture, and firewood for egg masses. Anyone that visits the Pennsylvania or New Jersey Quarantine Areas should thoroughly inspect their vehicle, luggage and gear for SLF and egg masses before leaving and scrape off all egg masses.
A Smartphone application is also available to help citizens and conservation professionals quickly and easily report new invasive species sightings directly to New York’s invasive species database from their phones. For more information, visit http://www.nyimapinvasives.org/
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.
