Ithaca, NY; February 27, 2018.  Northern New York farmers interested in protecting their alfalfa crops from the devastating alfalfa snout beetle can take advantage of discounts from the Cornell University laboratory raising the biocontrol nematodes that have been proven to reduce not only populations of snout beetle, but other crop pests as well.

Research funded long-term by the farmer-driven Northern New York Agricultural Development Program developed the science needed to pioneer the use of native nematodes, tiny insect-attack worms, as a biocontrol to suppress the spread of the destructive insect.

Recent field trials funded by the Northern New York Agricultural Development Program indicate that the biocontrol nematodes are also having an impact on corn rootworm after a field treated with the nematodes is rotated from alfalfa into corn.

Research elsewhere in the state has shown the biocontrol nematodes can reduce white grub and wireworm populations.

It requires three to five years to totally inoculate a farm with nematodes to reduce the snout beetle populations to a manageable level.

Cornell entomologist Dr. Elson Shields and Research Support Specialist Antonio Testa who developed the protocol for the use and rearing of the biocontrol nematodes recommend application on alfalfa fields in their seeding year or first production year for best results. Based on recent research trials, application can also be made to cornfields.

The Shields Lab at Cornell University that has reared the biocontrol nematodes as part of its research mandate is offering a discount for orders placed for delivery by June 15 for application within the following 3 to 5 days. This advance order deadline is April 28 and an additional ten percent applies for payment in advance or on delivery.

After the April 28 deadline, a ten percent discount applies to any order paid upon delivery. Farmers must contact the lab at no later than 45 days prior to a planned application based on their 2018 alfalfa cutting schedule.

Biocontrol nematode application must be made before September 15.

The cost is $28 per acre before discount.

The Shields’ Lab will only be providing the nematodes through 2021, opening an opportunity for business development to continue to supply the biocontrol nematodes to area farmers. While one nematode rearing business has been developed as a result of this research, others are needed. The Shields’ Lab will assist individuals seriously interested in rearing the biocontrol nematodes as a business.

Farmers who wish to rear their own biocontrol nematodes may also contact the Shields’ Lab for assistance.

Alfalfa snout beetle is known to exist across the six northernmost counties of New York State, in Oswego, Cayuga, and Wayne counties in NY, and in southeastern Ontario, Canada. The beetle can destroy entire fields of alfalfa in one growing season. The use of the nematode biocontrol developed in Northern New York is now being trialed in several U.S. states.

Northern N.Y.  Two farm tours and a workshop in March will showcase season extension vegetable production, including the results of research funded by the farmer-driven with funding support from the Northern New York Agricultural Development Program serving Clinton, Essex, Franklin, Jefferson, Lewis and St. Lawrence counties. The tours, organized by Cornell Cooperative Extension, will visit growers known for their success with winter season production of fresh produce.

A Monday, March 5 tour at Pleasant Valley Farm, owned by Paul and Sandy Arnold in Argyle, NY, will be available by pre-registration only. Paul, Sandy and Kim Arnold will talk with tour visitors about how they grow winter vegetables with little to no heat in their high tunnels. The Arnolds have been selling winter-grown produce at markets since 2006. They have used low tunnels since 1993. Visitors will see tunnels in full production. Tour organizer Amy Ivy, a regional vegetable specialist with the Eastern New York Commercial Horticulture Program, says, “The Arnolds run one of the best known winter growing operations in New York State.”

Space is limited for the free March 5 tour; preference will be given to commercial growers and would-be growers in Clinton, Essex, Franklin, Jefferson, Lewis and St. Lawrence counties. Register at https://enych.cce.cornell.edu/event.php?id=904 or contact Amy Ivy at adi2@cornell.edu, 518-570-5991.

On Saturday, March 24, Ivy will lead a “Growing Vegetables to Sell in Northern New York” workshop for those already commercially growing vegetables and those considering expanding their vegetable production to commercial scale. She will focus on growing vegetables in the spring and fall seasons in spite of the cold climate of Northern New York. The discussion will include using high and low tunnels and row covers.

This free 10 am to 12 pm workshop will be held at Colwell’s Farm Market and Garden Center in Glenfield, NY. Registration is required by March 21. Signup online at https://reg.cce.cornell.edu/GrowingVegetables_223 or contact Mellissa Spence at Cornell Cooperative Extension Lewis County at mms427@cornell.edu, 315-376-5270.

Northern N.Y.  The farmer-driven Northern New York Agricultural Development Program has posted its annual report at www.nnyagdev.org. The four-page report notes how recent research is helping regional farmers respond to hot and cold climate extremes impacting dairy calves and cows, field crops, and wine grapes. Also highlighted are projects addressing:
. the first-ever Northern New York bee colony health survey

. recently emerging crop pests, such as Western bean cutworm

. season extension and new product opportunities for the NNY maple industry, and

. field trials demonstrating how tomato growers can save time.

Farmer comments in the report indicate how applying the results of the research funded by the Northern New York Agricultural Development Program benefitted their business from reducing costs and making it easier to plant and harvest crops to identifying ways to develop extra income using existing resources.

Cornell University Nutrient Management Program Director Dr. Quirine M. Ketterings is cited in the report crediting the farmers and farm advisers in Northern New York as “the frontrunners” prompting re-evaluation of the Cornell corn production guidelines. The farmers who prioritize and select projects for Northern New York Agricultural Development Program funding requested research into how advances in corn breeding and production practices are impacting crop yield and whether it was time to update the associated nitrogen application guidelines for agronomic and economic efficiency.

The report notes that over a three-year study, completed in 2017, one-third of NNY fields tested in the project yielded less than 90 percent of their expected potential while 26 percent yielded more than 110 percent of their expected yield. This research enters Phase 2 in 2018.

A brief section in the report points to multi-state interest in the biocontrol crop pest solution built by the long-term commitment of the farmers of the Northern New York Agricultural Development Program to developing the science needed to manage the devastating alfalfa snout beetle.

A one-application treatment with native NY nematodes, combined with successively-bred, increasingly alfalfa snout beetle-resistant varieties of alfalfa, has restored production of the important dairy forage crop. This biocontrol has shown promise for controlling pests in other field crops and berries and is now being evaluated in field trials in elsewhere in New York State and in New Mexico, Texas, Ohio, and Michigan.

Posted with the annual report are summaries of maple, horticultural, and dairy and field crops-related projects funded by the NNYADP.

Northern N.Y.; December 12, 2017.  Research funded by the farmer-driven Northern New York Agricultural Development Program is helping regional dairies reduce the risk of winter-related mastitis.

The results of a study evaluating the use of two types of dairy cow udder applications for mastitis prevention are posted at www.nnyagdev.org.

Udder care on dairy farms includes the antiseptic practice of teat dipping prior to and after milking. During winter months, some farms modify teat dipping practices to reduce chapping and teat injury. The practices include blotting the teat end after post dipping to reduce excess moisture, switching to a different formulation of dip intended for winter use, or switching to a powder-based dip.

From early January to mid-February 2016, Cornell Cooperative Extension Regional Dairy Specialist Dr. Kimberley Morrill in collaboration with Cornell Quality Milk Production Services in Canton, NY, evaluated the use of a powdered chlorhexidine acetate teat dip vs. a traditional 1 percent iodine foam post-milking application.

The study was conducted with 331 Holstein milking cows in the dairy herd at Miner Institute in Chazy, NY.

Studies conducted on dairy farms in Idaho and Iowa respectively indicated that the powdered teat dip was as effective as iodine dip at controlling environmentally-based infections but increased the risk of contagious mastitis due to Staph aureus, a common mastitis pathogen.

Only 13 cases of clinical mastitis were seen among the 331 cows in the Northern New York study. Evaluation revealed no difference in clinical mastitis between the cows receiving the iodine teat dip and those treated with the powdered dip. The post-dip treatment with the powder did significantly increase the risk of a positive culture for Staph aureus and minor organisms and even more so the risk for a Streptococcus spp. or coliform-based infection.

Morrill notes that the research was conducted during a temperate winter, with temperatures ranging from 23 to 62.8 degrees Fahrenheit.

“This research suggests that powdered teat dip increases the risk of subclinical mastitis as compared to using a traditional iodine-based dip. To form a definitive recommendation, more trials are needed under the harsher winter conditions that are more typical of a Northern New York winter and might have produced different results,” Morrill said.

To reduce the risk of cold weather-related mastitis regardless of pre and post-milking application, Morrill advises dairy operators to make sure hygienic milking protocols are being used, equipment is well maintained, and teats are dry before the cows leave the milking parlor.

The results of this Northern New York Agricultural Development Program–funded dairy research were shared at the 2017 National Mastitis Council meeting.
