by Debra E. Marvin Comments Off on Weeding Now Reduces Weeds Later
Dr. Bryan Brown examines a single WATERHEMP plant capable of producing thousands of seeds.
Summer annual weeds start flowering in early August, so it’s important to control them beforehand to prevent seed production. This is true for commercial growers and for homeowners. One of the most prolific is waterhemp, a bane to growers because it’s also resistant to herbicides. According to our INTEGRATED WEED MANAGEMENT SPECIALIST, DR. BRYAN BROWN, waterhemp is likely resistant to herbicide Groups 2, 5, and 9 in NY.
That’s why Bryan is collaborating with growers and researchers around the state to investigate other controls, including cultivation, cover cropping, and even a device that zaps weeds with electricity. Funding for this work was provided by the Farm Viability Institute.
“Here we’re removing waterhemp that survived some of our herbicide treatments in soybeans. Because this trial is done in a grower’s field and we don’t want it to spread, we’re removing it before it sets seed (up to 500,000).”
While other pigweed species have short hairs on their stems, waterhemp and Palmer amaranth have smooth stems. The best way to distinguish waterhemp and Palmer amaranth is to rip off one of the lower leaves. Another characteristic of waterhemp and Palmer amaranth is separate male (pollen producing) and female (seed producing) plants. Herbicide resistance traits can transfer by pollen, which has allowed these weeds to develop resistance faster.
To prevent these weeds from taking hold, growers are also recommended to start weed-free with tillage, followed by a 2-pass program of residual and post-emergence herbicides that utilizes several effective sites of action. Foliar applied herbicides should be used when these weeds are less than four inches tall. Since these weeds emerge over a broader timeframe than most weeds, mid-season residual herbicide applications should be considered, along with increased planting density or tighter row spacing to help close the canopy earlier.

If you do find yourself with escapes of these weeds, it makes economic sense to go hand-rogue those weeds out of your fields rather than deal with 200,000 to one million seeds in your soil from each weed. If there are too many to bag up by hand, consider sacrificing that patch of your crop by mowing and tilling the area before the weeds produce seed. Avoid harvesting these areas. Combines are especially good at spreading weed seeds. If you must harvest these areas, know that combines can carry 150 pounds of plant material even you think it’s empty, so check out some of the great online videos on how to clean them out after going through weedy fields.
The weakness of waterhemp and Palmer amaranth is the short lifespan of their seeds in the soil. Of those that don’t germinate, very few will survive in the soil for more than four years. So, if you can keep it under control for four years, you won’t have much of it after that. But as one Pennsylvania grower put it, “the cheapest way to control Palmer amaranth is to never get it in the first place.” So, it’s important to make sure that your seed, feed, bedding, and equipment are clean from the start.
Dr. Bryan Brown works with growers, extension educators, industry leaders, and researchers to address knowledge gaps in weed IPM and develop programming to improve adoption of effective weed management practices. His work covers all agricultural crops throughout New York.

by Debra E. Marvin Comments Off on Senior Worm Wrangler Safeguards North Country Crops, wins Excellence in IPM Award
Press Release by Mariah Courtney Mottley. Media contact: Jaime Cummings
Elson Shields, a Cornell entomology professor, received an Excellence in Integrated Pest Management (IPM) Award from the New York State Integrated Pest Management Program (NYSIPM) at Cornell University’s Aurora Farm Field Day on the Musgrave Research Farm. NYSIPM 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 in their businesses, schools, communities, and farms, and who develop new tools and tactics for sharing these practices.

The alfalfa snout beetle, an invasive pest, is a perennial threat to north country alfalfa. In the absence of any registered insecticides for this pest, growers are forced to only use cultural and biological controls. Shields found success protecting alfalfa from the snout beetle with the use of native entomopathogenic nematodes (EPNs). Nematodes are tiny worms that parasitize and eventually kill the beetle larvae, and stay in the soil to infect future generations of the pest. Shields pioneered the use of nematodes that persist in the soil, and has been able to control snout beetles as long as six years after a single application of EPNs.
Shields has taught growers to rear the EPNs and to apply them to their own crops. Dr. Shields is also exploring ways to use these beneficial nematodes to protect specialty crops. He works with agribusiness consultants in the private sector and other researchers in the public sector. His effective strategy with persistent EPNs has been featured in trade journals such as Growing Produce, Good Fruit Grower and Dairy Herd Management. He received an Entomological Foundation Award for Excellence in IPM in 2013, and his promotion of persistent EPNs is being widely adopted.

By studying the persistence of nematodes applied to alfalfa through a crop rotation that included several years of corn, Shields observed that EPNs were also helping to control the corn rootworm, on their vacation time from alfalfa. Through collaborations with horticultural researchers, Shields is working on applying persistent EPNs as biological controls in crops such as strawberry, cranberry, sweet potato and turf. He is also studying the potential for using these techniques on greenhouse ornamentals.
Margaret Smith, Professor of Plant Breeding and Genetics at Cornell University, commends Shields’ willingness to question standard pest management orthodoxy and to follow research results wherever they might lead. She continues, “Elson’s snout beetle IPM effort is an exemplar of an outstanding public sector pest management program. Shields has done pioneering, innovating, and broadly effective research on an array of crops. His record of success will be hard to match.”
Laura McDermott, Regional Extension Specialist, says: “Dr. Shields’ work with native entomopathogenic nematodes is some of the most exciting applied research I’ve been involved with in my 30-year extension career. This integration of a biological control method as a way to manage difficult soil-borne insect pests is inexpensive, effective, and truly sustainable. Elson ALWAYS has the growers in the forefront of his mind. His efforts to teach farmers how to raise and apply these nematodes is testimony to his understanding of their abilities.”
“New York Agriculture, including the dairy, vegetable and fruit industries, have benefitted greatly from Elson’s vision and willingness to go above and beyond what is expected,” says Teresa Rusinek, Extension Associate for Vegetable Production in Cornell Cooperative Extension of Ulster County. She continues, “I’ve observed at our field meetings and farm demo work that growers easily understand the system and readily adopt the biocontrol strategies Elson’s developed.”

by Debra E. Marvin Comments Off on Pollinator Protection Resources

More and more homeowners and small-gardeners are choosing to reduce or end their use of pesticides. Not just for the health of their family and pets, but to reduce the risk of harming pollinators. Growers and farmers have multiple reasons to reduce pesticide use: reduced cost, reduced health risk to their families and employees, lost revenues in an ever-growing marketplace asking for ‘organic’ produce, and reducing pesticide resistance in pests. Yet high pest pressure in commercial operations, even organic growers, is the reality.
For those responsible for growing our food, chemical effects on pollinators have been a concern for many years. Loss of honeybee populations have been tied to multiple sources which, when put together, have a multiplied effect: colony die off. And we all know that loss of pollinators has a significant effect on food production.
Growers and farmers must examine many integrated pest management options–that’s why we’ve been examining and sharing science-based research for over thirty years!
Recently, Dr. Juliet Carroll provided some great pollinator photos on her SWD (that’s Spotted Wing Drosophila) blog and she suggested we share her list of pollinator resources for fruit growers.

by Debra E. Marvin Comments Off on NEWA “Survey Says…”
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.

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.

KEMPTVILLE, ONTARIO. — On my twice-monthly drive on Highway 416 between Prescott and Ottawa, I pass the sign for Kemptville, a town of about 3,500 which lies roughly 40 km north of the St. Lawrence. It has a rich history, and no doubt is a fine place to live, but one of these days I need to stop there to verify that Kemptville is in fact a village of surpassing tidiness. (It’s Exit 34 in case anyone wants to take some field notes and get back to me.)
Most of us would prefer not to live in totally unkempt surroundings, but Western culture may have taken sanitation a bit too far. Claims that cleanliness is next to godliness have yet to be proven by science, but research does indicate a neat, well-coiffed landscape is bad for bees and other pollinators.
Dandelions are an essential early-season flowers for our 416 species of wild bees in New York.
With all due respect to honeybees, they are seldom required to produce fruits and vegetables. Please don’t spread this around, as I do not want to tarnish their public image. But the fact is that wild bees, along with other insects and the odd vertebrate here and there, do a bang-up job pollinating our crops, provided there are enough types of wild plants (i.e., messiness) around to keep them happy for the rest of the season.
As landscapes become neater and less diverse, wild bees cannot find enough natural foods to keep them in the neighborhood for the few weeks of the year we’d like them to wallow around in our apple or cucumber flowers. In sterile, highly manipulated environments like almond groves and suburban tracts, honeybees are critical.
Dr. Scott McArt, a bee specialist at Cornell’s Dyce Laboratory for Bee Research, says there are an estimated 416 species of wild bees in New York State. When I estimate stuff, the numbers tend to be less exact, such as “more than three,” but I’ve met Dr. McArt, and I trust him on this count. Dr. McArt is quick to point out that wild critters take care of things just fine in most places. He has cataloged exactly 110 species of wild bees visiting apple blossoms in commercial orchards, and in the vast majority of NYS orchards studied, honeybees have no bearing on pollination rates. My object is not to malign honeybees, but to point out that if we learn to live with a bit more unkemptness, we will improve the health of wild bees, wildflowers, food crops, and ourselves in the process.
Dr. McArt has cataloged exactly 110 species of wild bees visiting apple blossoms in commercial orchards, and in the vast majority of NYS orchards studied, honeybees have no bearing on pollination rates. There was a presentation about it at the 2015 Pollinator Conference.
Messiness also takes pressure off managed honeybees, an increasingly fragile species, by providing them a rich source of wild, non-sprayed nectar and pollen. Orchardists do not spray insecticides when their crops are flowering because they know it will kill bees. But many fungicides, which are not intended to kill insects, are sprayed during bloom. One of the unexpected findings of research done through the Dyce Lab is that non-lethal sprays like fungicides are directly linked with the decline of both wild bees and honeybees. But banning a particular chemical is not a panacea—the situation is far more complex than that. What is needed to save bees of all stripes is a real change in mindset regarding landscape aesthetics.
This garden at Bethpage State Park Golf Course is an excellent example of entropy. Primarily established with native wildflowers, there are also a significant number of volunteers. NYS IPM staff found over 100 different species of insects, primarily bees and wasps, taking advantage of the bounty.
Increasing the entropy on one’s property is as easy as falling off a log (which of course is a literal example of increased entropy). Pollinators need plants which bloom at all different times, grow at various heights, and have a multitude of flower shapes and structures. For greater abundance and diversity of wild flowering plants, all you need to do is stop. Stop constantly mowing everything. Choose some places to mow once a year in the late fall, and others where you will mow every second third year. Stop using herbicides, both the broadleaf kind and the non-selective type.
Before you know it, elderberry and raspberry will spring up. Woody plants like dogwoods and viburnums will start to appear. Coltsfoot and dandelions, essential early-season flowers, will come back. Asters and goldenrod (which by the way do not cause allergies), highly important late-season sources of nectar and pollen, will likewise return.
Despite their unassuming flowers, Virginia creeper attracts a large number of pollinating bees and wasps. Photo: Joellen Lampman
Wild grape, virgin’s bower, Virginia creeper and wild cucumber will ramble around, without any help whatsoever. However, you may choose to help this process along by sowing perennial or self-seeding wildflowers like purple coneflower, foxglove, bee balm, mint, or lupine. Even dandelion is worth planting. You’ll not only get more wild pollinators, you’ll also see more birds. Redstarts, tanagers, orioles, hummingbirds, catbirds, waxwings and more will be attracted to such glorious neglect. No feeders required.
I strongly advocate for more chaos in the plant department, even if the local Chamber of Commerce or Tourism Board frowns upon it. Remember, just because you’re an unkempt community doesn’t mean you have to change the name of your town.
Christy Hoepting grew up on a small farm north of Toronto, Ontario. Enrolling at the University of Guelph, a top-tier ag school, was a natural fit. And though she focused on onion production while earning her master’s degree, she never dreamed she’d make a career of it. But then her advisor told her that a job with cooperative extension had opened up in western New York. She suggested she apply. The interview, after all, would be a good learning experience.
“What’s extension?” Christy remembers asking. But exceptional preparation and delivery were second nature. She got the job.
“I didn’t know the destination on the road I was traveling,” Christy says. “But I sure knew when I had arrived.” Need we say she loves her job?
This cover shot says it all.
Few people know onions inside-out as well as Christy Hoepting does. That “inside” part is critical. If you’re a farmer, you win when your onions pay their way; in a good year you could make upward of $4000 per acre. But you lose when one too many onion thrips — tiny pests, hard to find — sneaks between the leaf folds and starts laying eggs within its tender tissues. Or when pathogens hiding beneath the skin of healthy-looking onions trigger the long road to decline in a crop you counted on to get you through the winter.
Which is why Christy has conducted hundreds of on-farm research trials in plant pathology, entomology, weed science, cultural practices and crop nutrition. She’s presented at scores of stakeholder and scientific meetings and published scores of articles and research papers.
It’s also why she scouts farm fields relentlessly — a core practice of IPM — tracking every movement of insect and disease pests. And growers from miles around know that when Tuesday morning rolls around, they’ll meet at a corner of the road and Christy will recount what she’s seen.
It’s Tuesday. That means it’s muck donut hour.
Christy calls it the “Muck Donut Hour,” and it doesn’t take long for the conversation to start rolling. “I’m constantly tweaking our recommendations based on our research, of course, but also on what I hear from growers at the corner of the road,” Christy says.
Now for her exemplary work on behalf of farmers, not just in the rich muck-soil region of western New York but statewide and nationally, the New York State Integrated Pest Management Program (NYS IPM) presented an Excellence in IPM award to Christy Hoepting on March 8, 2017 at Cornell Cooperative Extension’s “Elba Muck Region Onion School” in Albion, New York.
