The December issue of Cornell’s What’s Cropping Up? newsletter includes an article by Jaime A. Cummings and Gary C. Bergstrom of the School of Integrative Plant Science.

The article: Resistance to Brown Stem Rot May Be Needed in Future Soybean Varieties for New York State notes the funding support of the Northern New York Agricultural Development Program for a survey of corn and soybean diseases in the NNY region in 2013-2014.

A potentially yield-reducing disease called ‘brown stem rot’ (BSR) was confirmed for the first time in New York soybean fields in 2013, and was found again in 2014. It showed up in some plants from soybean fields in Cayuga, Herkimer, Niagara, and Yates Counties collected by Cornell Cooperative Extension Educators Kevin Ganoe, Keith Severson, Michael Stanyard, and Bill Verbeten, with support from the New York Soybean Check-off Program. The disease was diagnosed in the Field Crops Pathology Laboratory at Cornell based on characteristic symptoms and the laboratory isolation of the causal fungus and confirmation of a portion of its signature DNA sequence. So far, BSR has not been detected outside of the four counties mentioned above. It is noteworthy that BSR was not detected in soybean fields in northern New York scouted in 2013 and 2014 by CCE Educators Michael Hunter and Kitty O’Neil, with support from the Northern New York Agricultural Development Program.

Please see two recent media stories on the NNYADP-funded alfalfa snout beetle control project that developed the use of native NY nematodes to help manage the highly-destructive alfalfa pest, the alfalfa snout beetle.

A biocontrol treatment developed to help Northern New York alfalfa growers is now showing early promise of proving useful to New York apple growers.

Early field trials in four NY orchard plantings have shown a reduction of 70 to 97 percent, compared with untreated plantings, in the populations of plum curculio, a key pest of eastern U.S. apple crops.

With long-term funding from the farmer-driven Northern New York Agricultural Development Program, Cornell University entomologist Elson Shields developed a biocontrol protocol for using a combination of native New York nematodes to reduce alfalfa snout beetle populations in NNY alfalfa crops.

Shields and Cornell colleague Art Agnello are now applying nematodes to control plum curculio in organic-production apple plantings.

Note: The NNYADP has three new on-farm demonstration projects on dairy farms in Northern New York showing the value of using the nematodes to reduce alfalfa snout beetle/ASB populations. Those farms are in the North Bangor/Malone area in Franklin County, at Brier Hill in St. Lawrence County, and in Turin/Lewis County.

The NNYADP is also funding the selective breeding of alfalfa snout beetle-resistant varieties of alfalfa to give farmers a one-two punch for managing ASB.

CCE Jefferson-Lewis Field Crops Specialist Mike Hunter asks the question: Do you have Alfalfa Snout Beetles on your farm? in the October 2014 issue of the CCE newsletters for Jefferson and Lewis counties.

He notes “Every year we discover new infestations of alfalfa snout beetles on farms.”

The NNYADP funded long-term research that is helping farmers use a cost-effective combination of biocontrol nematodes and ASB-resistant alfalfa varieties to control the highly destructive pest.
