Two major systems brought significant amounts of rain to all of New York State this past weekend. Tropical Storm Fay moved up the Hudson River Valley while a large front from the West hit western and central NY Saturday and Sunday.
7-day rainfall totals for New York State as of 12 July 2020.
Most counties and townships received a minimum half inch of rain across the state, which was timely given the fact that most of NY had transitioned to abnormally dry conditions, or moderate to severe drought in some areas, as of 10 July. Click here for additional drought status information.
More than 3 inches of rain were recorded in Catteraugus, Lewis, Madison, Oneida, Onondaga, Orange, Oswego, Rockland, Sullivan, and Westchester Counties as well as all boroughs of New York City. Smaller areas of Livingston, Monroe, Ontario, Seneca, and Yates Counties also received similar amounts.
Lumberland and Highland Townships in the southwest corner of Sullivan County may have experienced rainfall in excess of 8 inches.

Protecting bees and other pollinators has become an important social issue. But beekeeping, and the 20,000 species of bees worldwide, have been providing livelihoods, much of our food supply, and important biodiversity for thousands of years. Today, we help celebrate the first official World Bee Day as proclaimed by the U.N. through their food and agriculture organization.
We’ve collected some of our blog posts supporting pollinator protection (see below). First, here’s some facts from the UN’s Food and Agriculture Organization:
HONEY: Honey is a nutritious, healthy and natural food produced by the bees. Its benefits go beyond its use as a sweetener as it contains several minerals, enzymes, vitamins and proteins that confer unique nutritious and organoleptic properties. Honey can be monofloral if one specific plant nectar and pollen content prevails in pre-defined percentages or polyfloral if it contains an unspecified mix of different nectars and pollens. Due to environmental, geographical and climatic conditions honey may vary in pollen content and relative humidity. Honey is produced in all five continents and its consumption varies from country to country also due to cultural reasons and eating habits.
HIVE PRODUCTS: Honey bees may provide livelihood or a source of income for many beekeepers all over the world. This could happen through the services provided by the bees (mainly pollination service, apitherapy and apitourism), or directly through the bee products. The last include: alive bees to guarantee always new queen bees or bee packs, honey, pollen, wax, propolis, royal jelly and venom. Bee products may be used as food for humans, feed for animals, cosmetics, medicines used in conventional medicine (mainly vaccination), or in apitherapy, or other like manifold products, carpentry, attractant, sweeteners, etc.
POLLINATORS: Disappearing pollinators can mean losing some of the nutritious food we need for a healthy diet. The decline of pollinators could have disastrous effects for our future of food. Their absence would jeopardize the three-quarters of the world’s crops that depend at least in part on pollination, including apples, avocadoes, pears and pumpkins. And enhancing pollination isn’t just about mitigating disaster – with improved management, pollination has the potential to increase agricultural yields and quality. Pollinators also play a crucial role in maintaining and enhancing biodiversity thus improving the resilience of plants to climate change and other environmental threats.
THE NYS IPM Program is proud to consider POLLINATOR PROTECTION part of our focus. Visit these topics on this blog, the Think IPM Blog:
All crops have pests. Managing them on certified organic farms is firmly rooted in IPM practices such as crop rotation, sanitation, and the use of pest-resistant varieties. In fact, it’s written into the regulations. But despite the best IPM prevention practices, pesticides are still needed for certain stubborn pests. With organic vegetable production gaining in importance in New York—a 28% increase in the number of farms from 2011 to 2016—growers have an even greater need for objective information about allowed pest management products.
To provide that info, we teamed up with Cornell AgriTech faculty members Chris Smart, Brian Nault, and Tony Shelton to conduct trials. At the end of nine years, we have many successes that are effective options for cucurbit powdery mildew, squash vine borer, worms on brassicas, potato leafhopper, and others.
Alas, some pests still have us stymied, namely striped cucumber beetle and cucurbit downy mildew, so pesticide testing will continue. Next up, we focus on pests, beneficials, and weed IPM in organic squash production systems. And, to accommodate the increasing number of researchers working in organic systems, we’re helping Cornell AgriTech transition 24 acres of research fields into certified organic production. IPM and organic: natural partners.
(Above) Double damage. The sharp-dressed striped cucumber beetle causes direct damage, massing on newly emerged or transplanted seedlings and sometimes chewing them to the ground, while also transmitting a sometimes-fatal bacterial wilt.
Don’t Get Ticked NY!
(Above) Ticks prefer moist, warm places. Teach children to make tick-checks a personal habit—the last defense against disease transmission. Knowing the spots and bumps on their skin helps them recognize new ones—new ones that happen to have legs.
Ticks are really ticking off New Yorkers worried about Lyme disease, the United States’ number one vector-borne pathogen. It’s transmitted by the blacklegged tick found abundantly throughout our state. This particular pest can also spread diseases like anaplasmosis, babesiosis, and Powassan virus. Unfortunately, additional tick species abound, and together, the many illnesses they can cause are serious threats to human health. That’s why NYSIPM is committed to reducing the impact of these little blood-suckers.
Recognizing our ability to effectively convey key risk-reducing strategies, the NYS Senate’s Task Force on Lyme and Tick-Borne Diseases joined the fight by funding our Don’t Get Ticked NY campaign. We provide easy-to-understand information at the website, and distribute ID cards, infographics and tick removal kits to educators and the public statewide through community events, extension offices and BOCES. Last year we handed out almost 50,000 tick ID cards, a few thousand tick removal kits, and directly reached over 5,000 people.
“Tick-educated” New Yorkers now recognize tick habitats, and—rather than avoid the outdoors—now know how to look and feel for ticks during their daily tick check. While threats from ticks continue to increase, so does New Yorkers’ awareness of how to stave them off. So please … don’t get ticked, New York.
(Above) Get the pointy. Our Don’t Get Ticked New York Tick Kits are popular handouts at events across the state. You can make your own by gathering pointy tweezers, a magnifier, a mirror, alcohol wipes, and a vial or plastic bag to store the offender. But kits won’t help you if you don’t have them nearby. Our tick cards are the perfect resource to have on hand, and you can print out the same graphics from our website at www.DontGetTickedNY.org.

by Debra E. Marvin Comments Off on Our 2018-2019 Annual Report: #5 Pollinator Habitat, and NEWA
Dwindling bee numbers is a problem. The question is not should we protect pollinators and create habitat, but how? What’s the best method? The most economical? The best bee habitats—made up of plants of varying sizes and bloom times—are easy on the eye. They’re also excellent real estate for other helpers, like spiders and certain beetles, that eat pests. So can pollinator habitats provide biocontrol benefits too?
To answer these questions, our team set up pollinator habitat plots around our Christmas tree research planting—testing establishment methods, evaluating weeds, counting and identifying the insects attracted, and studying the biocontrol value to the trees.
ABOVE: Flowers providing pollen or nectar are important to both pollinators and many pest-eating “beneficial” insects. You can help them by choosing a variety of plants that bloom from early spring through late fall with flowers of diverse shapes. This Echinacea makes pollen and nectar readily accessible to both small and large bees, proving that it’s not just their beauty that’s worthy of our admiration.
Wildflower and grass species favored by pollinators were chosen from lists of native perennials. Some started from seed; others were transplants. By the end of the first season, natural enemies and pollinators had arrived—including lady beetles, lacewings, predatory stink bugs, spiders, hoverflies, predatory beetles, butterflies, and many wild bees. This year the plots have matured even more. We collected flying insects with sweep nets, counted butterflies, and caught wasps and bees in brightly colored bowls of soapy water. We even had a method for catching insects moving along the ground.
So far, we have lots of tips for helping growers and gardeners create their own beneficial insect habitat. As to fewer pests in Christmas trees? Time will tell.
What’s New with NEWA?
Are summer conditions becoming more unpredictable? Are you wondering how to make informed and timely decisions about pest management? If you say yes to both, you’re not alone. NEWA, the Network for Environment and Weather Applications, is here to help by providing live, on-farm decision support for fruit, vegetable, and field crops production. NEWA pairs real-time weather data from growers’ fields with online crop-specific pest forecasting. And it’s growing every year.
Developed by scientists with pest biology expertise, NEWA models predict disease progression, insect infestations, and crop phenology. Apple growers rely on apple scab forecasts in the spring, grape growers monitor grape berry moth risk through the summer, and field corn growers track western bean cutworm flights throughout the season to know when to scout.
Our latest survey proves NEWA’s unparalleled decision support to growers is working. Users attest they saved over $4,000 in spray costs and more than $33,000 in prevented crop losses annually.
NEWA partners with extension, industry, and academic partners statewide, including the Lake Erie Regional Grape Program that supports western New York’s Concord grape growers. Thanks to the close collaboration between NYSIPM, growers, and processors, that region benefited from the addition of 11 weather stations last year, a move that nearly doubled their decision-making power. NEWA also joined forces with the NYS Mesonet at the University at Albany, a collaboration that resulted in ten pilot locations across the state.
Today NEWA offers 42 models using data from 677 weather stations in 14 states. NEWA and NYSIPM support agriculture throughout New York and beyond. The latest forecast? The future looks bright.
An Onset Weather Station

by Debra E. Marvin Comments Off on Our 2018-2019 Annual Report: #4 In the Weeds and For the Birds
Herbicide resistant weeds. Got ‘em? Worried about ‘em? There are some bad ones out there. Some of the baddest in New York are horseweed, waterhemp, and Palmer amaranth. A result of repeated exposure to the same chemical sprays, these plants have given us all a lesson on the power of selection pressure. The crisis brought about by these super-tough weeds motivated NYSIPM to hire an integrated weed management specialist to help growers find a diverse blend of solutions. So what can be done? Instead of relying on herbicides alone, use the ‘many little hammers’ approach: attack weeds with a variety of tactics such as stacked cultivation—a mechanical method that undercuts, uproots, and then buries weeds. Because precision is key in stacked cultivation, GPS and camera guidance help keep tools in line. That’s the difference between destroying your weeds or your crop. What’s next? We’re providing input on the design of robots able to distinguish between the weeds and the crop—aka autonomous weed control. And we’re helping test an electric WeedZapper that has already demonstrated its effectiveness against horseweed. By integrating the latest technology with the oldest, IPM offers growers the many little hammers they need to create a resilient, robust weed management system for their farm.
(Above) Will waterhemp win? Facing a 56% decreased yield in this waterhemp-infested soybean field, NYSIPM’s Integrated Weed Management Specialist, Bryan Brown, leads a project funded by the New York Farm Viability Institute. This herbicide-resistant weed can grow an inch a day, and is an impressive seed producer. Through diversified approaches, the project has provided complete control of waterhemp in some trial sites, prompting 94% of attendees at field events to say they’ll follow the lead of this project and modify their tactics for weed control.
Anthraquinones are for the Birds
What do crows, ravens, blackbirds, starlings, grackles, Canada geese, gulls, and wild turkeys all have in common? They’re recurring pests of corn on New York farms, pulling seedlings out of the soil as soon as they emerge. Stony soils, and shallow and no-till plantings are most at risk.What’s a grower to do? Traditionally they lived with the losses, or replanted if there was time. One New York farmer was ready to quit until trying Avipel Shield, the biopesticide seed treatment containing anthraquinone, an extract found in rhubarb and many other plants. Apparently, birds don’t like it. So after a few nibbles of treated seed, they move on and look elsewhere for food. NYSIPM set out to test whether anthraquinone worked in fields that suffer major bird damage. Along with extension specialists in eight counties, we conducted trials on treated and untreated seeds in fields that typically suffer heavy loss to birds. Three years of data confirmed Avipel leaves a bad taste in birds’ mouths. Further trials will help farmers know whether treated seed is needed everywhere every year, or if random use can deter feeding. Meanwhile, these tasty results have been a hot topic at field meetings, crop congresses, and certified crop advisor trainings throughout the state.
(Above) Fully fledged. Field Crops & Livestock IPM Extension Educator Ken Wise believes this project’s secondary success was its considerable collaboration. Funding came from three different sources over the three-year period—NYSIPM, NYS Corn Growers Association, and the NYS Farm Viability Institute. Just as important was the partnership among 11 farmers, nine extension educators, and one faculty member

The sun was set; the night came on apace, And falling dews bewet around the place; The bat takes airy rounds on leathern wings, And the hoarse owl his woeful dirges sings. – John Gay

Bats are one of those creatures that instill fear in people. (Thanks, Hollywood.) But as all our New York bats eat insects, at a rate of around 700 insects per hour, they can play an important biocontrol role in our IPM programs.

There are two types of bats in the Northeast. Some species are communal and typically overwinter in caves, mines, and sometimes, to our consternation, our buildings. They include the little brown bat, big brown bat, eastern long-eared bat, eastern pipistrelle, small-footed myotis, and the federally endangered Indiana bat.
(If you find bats lodging in your attic, it is best to call in the professionals. They’ll work with you at the right times of the year to close up crevices and holes that let bats in. Closing up entry holes in the summer could trap baby bats inside. For more information, visit What’s Bugging You – How to deal with bats.)

Bats in the second group live largely solitary lives, roost primarily in tree canopies and cavities, and migrate south for the winter. These include the red bat, hoary bat, and silver-haired bat.
According to the Cornell publication, Bats in the Forest and Beyond, “in a study of a colony of 150 brown bats in an agricultural area, researchers estimated that the colony consumed over 1.25 million insects in a year. This is not surprising, considering that a single bat may eat 3,000 insects on a given summer night. Bats roosting and foraging in New York forests consume forest and eastern tent moths, and a variety of other potential forest pests”.

The legal status of bats varies from state to state. In New York, two species, the Indiana bat and the northern long-eared bat, are protected. However, the conservation of all bats is encouraged. This is particularly important since the populations of some bat species, especially the little brown bat, have been decimated by an introduced fungal disease, white-nose syndrome.
So what can we do to help? According to the Cornell Wildlife Health Center, “to minimize spread of the fungus [that causes white-nose syndrome], people should not handle bats, avoid entering caves and mines with bat colonies, and should decontaminate all equipment and clothing between caves and bat roosts”.
Leave or plant trees with deep furrowed bark such as shagbark hickory that provide roosing spots for bats. Allowing dead trees with peeling bark can also provide habitat. If you must take down these trees, avoid cutting from May to early August when bats are raising thier young. We can also install bat boxes, which mimic areas bats would naturally roost.

by Debra E. Marvin Comments Off on Highlights from the Northeast Mechanical Weed Control Expo
Weeding tools have come a long way! Last summer, Eric Gallandt invited me to present the results of my latest “stacked” cultivation trials at the Northeast Mechanical Weed Control Expo. I brought my camera along to document the exciting exhibits by vendors and other researchers. Stacked cultivation featured prominently, as did enhanced accuracy – achieved through improved steering capability or camera-guided tools.
(Above) KULT Kress demonstrated their camera guided sweeps and finger weeders (only one row operating). These weeds were too large for optimal finger weeder performance. In-row weeds are most effectively controlled when less than one inch tall.
(above) The camera guidance system display was brought out from the tractor cab to show participants how it focuses on green plants to determine the location of the crop row.
(above) HAK showcased a new cultivating tractor with sweeps (left), finger weeders (center), and tines for the wheel tracks (right).
(above) Steketee brought their Crumbler Rotors (left), finger weeders (center), and side knives (right).
(above) The cultivating tractor from Tilmor is reminiscent of the Allis Chalmers G, but notice the new crane-winch system for moving tools into place.
(above) Tilmor also demonstrated a walk-behind tractor with a potential “stacked” cultivation setup.
(above) Jen Goff, from Johnny’s Selected Seeds, showcased several innovative wheel hoes and hand tools.
(above) Ellen Mallory PhD, and Tom Molloy from UMaine discuss their results testing the potential of the CombCut and inter-row hoeing in small grains.
(above) “Stacking” cultivation tools is not just for vegetable crops, this combination has proved effective in small grains.

by Debra E. Marvin Comments Off on Soybean Disease Workshop at Cayuga County ‘Shop Meeting’
Soybean Disease Identification, Expansion of Soilborne Soybean Diseases and the Soybean Cyst Nematode in NYS, and Considerations for Soybean Seed Treatment Options for these Threats
Cayuga County CCE specialist Ron Kuck held a shop meeting at Dumond’s farm in Union Springs on February 19th. Jaime Cummings, Field Crops and Livestock IPM Coordinator at NYSIPM shared information on how to correctly identify, differentiate and manage soybean diseases, which seed treatments are most beneficial and cost-effective for soybeans in NY, and how to deal with the new soybean cyst nematode now that it’s been confirmed more widely in NY.
A good turnout on February 19 for a Cayuga County Shop Meeting. Growers concerned with soybean diseases heard the latest from NYSIPM’s Jaime Cummings.
Participants took a pre-workshop quiz to gauge their knowledge of the subject, and a post-workshop quiz to see how much they learned. And, they learned a lot! The average quiz rating before the workshop was 57%, and was 87% after. This means a 30% knowledge gain regarding when and which management methods are most effective for each soybean disease, including when pesticides are not the best option, and how to incorporate integrated pest management options for minimizing losses to the soybean cyst nematode.
Soybean Sudden Death (SDS) Foliar Symptoms
Ron Kuck received positive feedback from a number of participants, who each said that they appreciated the workshop and Jaime’s expertise and enthusiasm on the subject matter.
About 35 farmers and agriculture professionals attended February’s Shop Meeting in Union Springs, NY.

Thank you to all who coordinated and attended this successful event.
Using several different cultivation implements at once, or “stacking” tools, can improve weed control effectiveness. From my work at the University of Maine, Eric Gallandt and I showed that certain cultivation tools work synergistically together, particularly those combinations that undercut, then uproot, then bury weeds. Unfortunately crop damage was high in the trial results from Maine. So in New York, I made some adjustments to be gentler on the crop – wider spacing between tools, removed center tines on the row harrow, and tested a new hiller to bury weeds without contacting the crop (Figure 1). And GPS guidance was a big improvement too!
Figure 1. Cultivation implements used in these trials were A) sweeps, B) finger weeders (yellow and row harrow (blue), and C) a disk hiller. For full explanation of implement adjustments and trial methods, see the project report at https://ecommons.cornell.edu/handle/1813/64539
Figure 2. Results of cultivation trials in snap beans. This was the first cultivation event following planting and tillage. At cultivation, snap beans were 6” tall, while weeds were 0.5” tall in 2018 and 1” tall in 2019.
Figure 3. Results of cultivation trials in beets. First cultivation occurred at either the 2-leaf stage or about one week later at the 4-leaf stage. 2019 beets trials were planted in the spring, whereas 2018 beets were planted late-summer, with lower-growing winter annual weeds present.
Overall, the adjustments made in these trials greatly reduced crop damage while weed control remained high. I was most impressed with the stacked combo of sweeps plus fingers plus disk hillers, which consistently controlled the greatest percentage of weeds. These results also demonstrate that in-row cultivation should not be conducted prior to the 4-leaf stage in beets. For more information on integrated weed management, contact email@example.com. This project was supported by a USDA NIFA CPPM.
