“None of us is as smart as all of us.” –Ken Blanchard
Each year, NYS IPM staff are busy blogging about relevant topics. Here’s a recap of some of our more popular 2019 offerings:
ThinkIPM is our catchall blog and a great way to keep a pulse on what’s happening in New York State IPM.
No one wants to find an embedded tick.
We have spent a lot of time in the past year talking about how to prevent tick bites, from dressing in long pants, using repellents, and conducting daily tick checks. But sometimes one gets past you and you discover that new lump behind your knee has legs. There are always question about what to do next, and Help! I found a tick on me! was the most popular 2019 blog post.

Spotted lanternfly was also on your mind, and Traveling for the Holidays? provided a checklist for those traveling within the spotted lanternfly quarantine zone. Trust us when we say that you do not want to unintentionally transport Spotted Lanternfly egg masses in New York state.
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 most popular Biocontrol Bytes offering was a guest post from our collegues in the Cornell’s School of Integrative Plant Science, section of Plant Pathology and Plant-Microbe Biology, Anna Wallis, Kerik Cox, and Mei-Wah Cho. They discussed moving beyond antibiotics to the use of biopesticides in the post, Battling Fire Blight with Biologicals.
When choosing the perfect tree, people usually consider variety, size, and shape. But with the phenomenon of a new invasive planthopper, Spotted Lanternfly (Lycorma delicatula) (SLF), the tree’s origin may be something to think about.
We always suggest fresh-cut trees from New York’s many great tree farms!
First of all, we’ll say it’s unlikely that SLF will be on your cut tree. Conifers are not a food source for this pest, but egg-laying females are indiscriminate as to where eggs are placed. That’s why we offer a list for travelers making their way through quarantined areas.

At this time of year, winter has killed off adults, but their hardy egg masses remain. Although ornamental in appearance, Spotted Lanternfly is one “ornament” you don’t want hatching from their mud-like egg masses and decorating your property this coming spring. SLF causes economic damage to agriculture, forestry and tourism, and is a major nuisance to homeowners. Learn more by visiting our SLF website!
We bring this up because the SLF quarantined areas of Pennsylvania (shown in blue on the map below) happen to be home to many Christmas tree farms (Berks, Bucks, Carbon, Chester, Dauphin, Delaware, Lancaster, Lebanon, Lehigh, Monroe, Montgomery, Northampton, Philadelphia, and Schuylkill).
Distribution map as of November 2019
If you’re buying a pre-cut Christmas tree, ask the seller where their trees came from. If it’s from PA, learn about this pest and inspect the trunk. But don’t stop there. Get into the habit of citizen science! “Scouting” (actively knowing how, why, and where to look) for pests gives you a critical role in stopping the spread.

What else can you do?
There are plenty of cut-your-own farms in New York with family-friendly atmosphere where you can get a fresh tree. If you don’t have time for a cut-your-own experience, ask your tree sellers if they’re aware of SLF risk on out-of-state trees. Awareness is key!
Here’s some Christmas Tree tips from our own Christmas Tree expert, IPM’s Brian C. Eschenaur:
2019 was an excellent growing season for Christmas Trees. We had more moderate summer temperatures and good rainfall this year. Those suitable growing conditions allowed trees to put on healthy new growth, and the fine weather gave Christmas tree growers good conditions to prune trees so they will be in great shape for harvest. This year’s early-November cold snap was also beneficial in “setting” the needles which is good for longer needle retention in some tree species.
Once in a while we hear from people concerned about the “single use” aspect of real Christmas trees. But considering the alternative of a plastic tree produced, then shipped from overseas, (and eventually ending up in a landfill), real trees have their benefits. They are a renewable resource and by buying locally you are supporting growers that will continue to maintain their fields which are part of the greenspace we all value.
Choose a variety and shape that fits your needs. Many growers are producing a wide variety of firs, spruces and even old-fashioned pines. Each variety tree offers its own shape, color, fragrance, and even branch stiffness which is important to consider for holding ornaments.
Trees always look smaller in the field so don’t forget the tape measure. Measure the floor to ceiling height before you go tree shopping and then while choosing so you end up with a tree that fits nicely into your home.
Don’t be afraid to bend the branches and shoots. Green needles should not come off in your hands. Also, the shoots should be flexible. Avoid a tree if the needles are shed or if the shoots break instead of flexing.
If possible, make a fresh cut on the bottom so the tree’s vascular tissue (pipe work) is not plugged and the tree can easily take up water. Then, if you’re not bringing it into the house right away, get the tree in a bucket of water outside.
Once you move your tree inside the house, don’t locate it next to a radiator, furnace vent or other heat source. And always remember to keep water in the tree stand topped off, so it never goes below the bottom of the trunk.
Whatever you choose to do, enjoy your “Holly Jolly Christmas” and hopefully “it’s the best time of the year.”

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.

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.
In late 2018, NEWA’s Coordinator, Dan Olmstead, and its creator, Dr. Juliet Carroll, concluded an assessment of a 2017 user survey. They, and the NEWA State Coordinators, reviewed user demographics, website content needs, and user experience before passing it on to Cornell’s Survey Research Institute.
The electronic survey included a subset of questions first asked in the 2007 survey. A summary of the 398 participants from 14 states provided a clear picture of NEWA’s impact. A more detailed summary has been shared in four posts at the NEWA Blog http://bitly12UatlMMW
Here’s the bottom line:
-NEWA is a reliable and trusted source of information among uses.
-All respondents said they would recommend NEW to other growers.
-NEWA provides reliable IPM information to support responsible management practices, enhance decision-making, and increase awareness of risks.
-96% of users say NEWA improves the timing of pesticide applications.
-NEWA has a positive impact on IPM practices.

Fewer vegetable than fruit models are available on NEWA. Cabbage maggot and onion maggot models are popular among growers (Fig. 2). Use percentages were based on the number of respondents to disease and insect model questions, which were 35 and 20, respectively. NEWA vegetable tool development is an area for future growth. In addition, promotion and education on how to use existing vegetable tools would increase use.
Dr. Juliet Carroll, Fruit IPM Coordinator, NYS IPM Program, NEWA founder
When putting the above statements into dollar figures, consider this:
Growers are saving money on an annual basis—an average of $4329—by reducing use of pesticide spray.
Estimated savings from crop loss, again on average, was $33,048.
Who uses NEWA? 75% are growers and 60% of them manage diversified farm operations.
20% of respondents managed farms smaller than 10 acres.
57% of respondents managed farms between 11 and 1000 acres.
4% had farms greater than 1000 acres.
Most NEWA growers grew apples, but a majority produced two or more commodities such as other tree fruit, grapes, berries, and tomatoes. Existing fruit and vegetable forecast tools will soon be joined by additional tools for field crops and ornamentals.
NEWA also provides links to other tools such as NOAA radar maps, USDA drought maps and websites that target particular problems like late blight or cucumber downy mildew.
Today we share a press release from Mariah Mottley Plumlee <email@example.com>
GENEVA NY, January 10, 2019: Alice Wise, Cornell Cooperative Extension of Suffolk County Viticulture and Research specialist, received an Excellence in Integrated Pest Management (IPM) Award from the New York State Integrated Pest Management Program (NYSIPM). The program develops sustainable ways to manage pests and helps people to use methods that minimize environmental, health and economic risks. The award honors individuals who encourage the adoption of IPM on their farms, businesses, schools, and communities, and who develop new tools and tactics for sharing these practices.
Alice cutting the last cluster (2015).
Wise received her award on January10 at the Long Island Agriculture Forum.
After a tenure of more than 25 years, Wise’s contribution to the wine and grape industry of Long Island is substantial and varied. The main focus of her IPM work has been to provide growers with information and best practices to reduce and optimize the use of pesticides. Wise has conducted research on under-trellis weed management, focusing on cover crop care, all with the eye toward decreasing the need for chemical use. She has promoted the deployment of netting to protect the grapes from migrating flocks of birds, and studied the effectiveness of leaf-pulling as a way to prevent cluster rots. She has also monitored the emergence and development of grapevine viruses.
Wise manages a 2.5 acre research vineyard, where she conducts variety trials in pursuit of desirable traits like disease resistance. She shares her evaluation of vine performance and fruit quality with wine growers, and contributes to multi-year studies on the topic. Her work has allowed growers to reduce their applications of pesticide while still producing high quality grapes for use in their winemaking.
Wise also conducts research in commercial vineyards on the role of mealybugs and fruit scale in the distribution of the leafroll virus—a virus potentially devastating to the wine industry. Wise has provided vintners with tools to identify and limit the in-vineyard movement of this worrisome disease. Through a project funded by NY Farm Viability Institute, Wise scouts vineyards every other week for hot spots and provides growers with row-by-row information on the unwanted pests, allowing them to target their pesticide applications more specifically.
Richard Olsen, Bedell Cellars, in Cutchogue New York, shared that “Alice is a committed and passionate researcher who has spent her career looking at ways to reduce our chemical inputs. Our industry on Long Island would not be as successful today if not for her dedicated work.”
Alice Wise with long time friends, Wayne Wilcox, emeritus grape pathologist, and Rick Dunst of Double A Vineyards.
Wise helped to develop guidelines and regulations for Long Island Sustainable Winegrowing (LISW), the only third-party certified program for vineyards on the East Coast. LISW focuses on the use of safe low-impact pest management while guaranteeing that pesticides that can leach into the groundwater are never used. This is critical in Suffolk County, where everyone’s drinking water comes from a sole source aquifer. Wise has used her email listserv to continuously educate and update grape growers on disease pressure, occurrence, insect control problems, and recommendations.
“It is hard to overestimate Alice’s impact on the development of sustainable viticulture on Long Island and the Eastern United States… Her regular advice, both public and private, has helped each of us to make the most conservative and appropriate use of all plant protection materials,” said Laurence Perrine, CEO, Long Island Sustainable Winegrowing.

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:
December’s wintery breath is already clouding the pond, frosting the pane, obscuring summer’s memory… ― John Geddes
Winter had an early showing in New York this year. So when the temperature hit 50oF yesterday, I took the opportunity to spend some time outside. And, as I had warned people that follow me and NYS IPM on social media with this great graphic by Matt Frye earlier today, the ticks were out and about. (Side note: follow us at www.facebook.com/NYSIPM and twitter.com/NYSIPM for up-to-date information you can use.)
Now, the ticks weren’t as active as the 70 oF day last February. I had to put in a little more effort to find them. But while tick dragging, I noticed where others regularly go off the beaten track (or, rather, create their own beaten track). We’re going to call this The Dog Zone.
There’s a perfectly good paved path, but the dog print laden path is inches from the woodline.
Let’s face it. Dogs want to stick their noses into interesting places, and there just aren’t that many interesting places on the pavement. So they will take advantage of the length of the leash to get off the pavement and follow the scent trails. And the smells of mice, chipmunks, squirrels, raccoons, deer, rabbits (you get the idea), are more likely to be wafting at the edge of the woods than in the short grass. I watched dog walkers leave the pavement themselves to indulge their furry friends. Unfortunately, ticks are more likely to be in those areas.
Talk to your vet about options to protect your pets from ticks and tick-borne diseases.
But the really important message here is that ticks are active during the winter. And even if the air temperature is less than 37oF, a protected, sun-exposed area next to a woodline can be significantly warmer. Last week a site we were monitoring had an air temperature of 40oF, but the ground temperature was 50.6oF. So I will end by emphasizing the need to protect yourself from ticks year-round and conduct a tick check EVERY DAY.
