Disease Study Group: Focus on new and emerging soybean diseases

PRINCIPAL INVESTIGATOR

Albert Tenuta

RESEARCH INSTITUTION

Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA)

EXTERNAL FUNDING PARTNERS

The Crop Protection Network (CPN) is a multi-state and international collaboration of university and provincial Extension specialists, and public and private professionals that provide unbiased, research-based information to farmers and agricultural personnel. This effort is currently supported by the North Central Soybean Research Program (NCSRP), United Soybean Board (USB), and Grain Farmers of Ontario along with OMAFRA. US partner institutions include Purdue University, Iowa State University, University of Wisconsin-Madison and Michigan State University as well as specialists/researchers from other Land Grant Universities. All Land Grant Universities involved are also supported by the United States Department of Agriculture.

PROJECT START

February 2013

PROJECT END

March 2016

OBJECTIVES

  • Organize a core group of Extension personnel including Ontario to annually identify and develop Extension material for new or emerging (endemic) diseases for Ontario and the Midwest US.
  • Provide information on multiple levels of Extension interface (print, web, video, smartphone, Ontario Grain Farmers magazine, etc.) to reach diverse groups of stakeholders.
  • Create a platform to host and brand Extension material developed in conjunction with the North Central Soybean Research Program and Grain Farmers of Ontario to facilitate updates and allow users to identify trusted sources of material through this branding partnership.
  • Provide current research summaries on emerging diseases to direct and coordinate future research priorities thereby minimizing duplication, maximizing resources and increasing response time.

IMPACT

  • The development and dissemination of Extension material developed in conjunction with the North Central Soybean Research Program and Grain Farmers of Ontario allows producers to make in-season decisions on diseases from a trusted source.
  • The ultimate goal is that industry personnel and soybean farmers will have an improved awareness of emerging diseases, and this information will prevent soybean/corn yield losses by identifying and managing present and future disease issues.

SCIENTIFIC SUMMARY

Disease severity and prevalence is impacted each year by changes in crop production practices and environmental conditions. There are diseases that are an annual threat, such as sudden death syndrome (SDS) and soybean cyst nematode (SCN), but many other diseases are sporadic, new, or emerging in the North Central Region of the USA and Ontario. These diseases are concerning to farmers due to the lack of Extension information available when outbreaks occur. In a traditional system, research is conducted and Extension materials are developed and disseminated at the end of the project. This creates a “gap” in industry and farmer awareness for emerging diseases, and prevents stakeholders from obtaining the most current information about emerging issues until research projects can be completed.

This project aims to develop a North Central Disease Study Group that will bridge the gap between research and Extension for emerging disease threats and provide industry and farmers with the most up-to-date information available about emerging diseases each year. We identified a group of Extension and research personnel to contribute information and technical expertise to Extension material focusing on new as well as emerging disease problems. The first product was on the new virus, Soybean Vein Necrosis Virus (SVNV), which was first observed to be widely distributed across the North Central Region and Ontario in 2012 and 2013. Our collaborative efforts and meetings generated nine publications to date with others in development as well as videos and other media products. All materials are drafted by the Crop Protection Network development team of which Albert Tenuta is the Ontario representative. We have developed the “Crop Protection Network” brand as a means to promote/represent Universities, NCSRP and Grain Farmers of Ontario on Extension material produced from this project. Web presence and optimization of web resources continue to be discussed, and inclusion of these materials on the Crop Protection Network website, NCSRP Plant Health Initiative website and Grain Farmers of Ontario website on the Production Resources page.

Brown marmorated stink bug monitoring for Ontario

Project Start

April 2012

Project End

April 2015

Objectives

  • Monitor corn and soybean fields in Ontario for brown marmorated stink bug presence and feeding damage.
  • Increase education and awareness of homeowners, growers and crop specialists.

Impact

  • The development of an early detection system to monitor brown marmorated stink bug (BMSB) will lead to a better understanding of their distribution and will facilitate rapid response and ensure implementation of appropriate management strategies to limit crop damage in corn and soybeans.
  • The education of corn and soybean producers, agricultural representatives, consultants, homeowners and citizen scientists on proper identification of BMSB will increase awareness and improve identification of overwintering sites and aid detection of this new invasive species.

Scientific Summary

Brown marmorated stink bug (BMSB), Halyomorpha halys Stål, is an invasive pest from Asia. It was first detected in Pennsylvania in 2001 and has since spread to 41 states and two provinces, including Ontario and Quebec. BMSB has become a significant pest of several host crops in the Mid-Atlantic US, including corn and soybeans. Corn kernels and soybean seeds are punctured by their piercing mouthparts, and injury results in discolouration and shrivelled, unmarketable product. BMSB is also a possible vector of purple seed stain and can delay maturity in soybeans and cause aborted ears in corn. The highly mobile BMSB are known to move between crops, extending the activity within a crop which results in additional monitoring and more intensive management practices. Only through monitoring, education and awareness are we able to detect their presence and respond accordingly.

This three year survey project aimed to monitor field crops and several urban, natural and high traffic/tourist locations with known tree host species. The project relied on collaboration between the extension personnel and summer staff from OMAFRA; researchers from University of Guelph and Agriculture and Agri-Food Canada; and 70 grower co-operators and crop consultants. Grower co-operators and crop consultants were involved in providing field sites to monitor throughout the summer. To determine tree host species for BMSB, the following host trees were targeted for sampling: buckthorn, ash, Catalpa sp., choke cherry, crab apple, dogwood, American cranberry bush, honeysuckle, lilac, American basswood, Manitoba maple or box elder, mulberry, rose, tree of heaven, walnut, and wild grape. Tree hosts were monitored early in the season, while host crops were monitored later in the season, when pods or corn ears were forming. Monitoring of field crop fields included 133 fields in 2012, 127 fields in 2013, and a more focused effort of 63 fields in 2014. Ontario was the first to confirm that buckthorn is a very good and long season host for BMSB, which due to the widespread distribution of this invasive plant in Ontario, increases the number of fields at risk. No field established BMSB populations were found in any host crops during this study. Through increase public awareness campaigns and establishment of the OMAFRA Agricultural Information Contact Centre as the key contact for suspect BMSB finds by homeowners and citizen scientists, we have determined that BMSB has spread across much of the province. Over 250 overwintering populations were confirmed by homeowners and four established breeding populations were found in urban settings by collaborating researchers. Through our monitoring efforts, BMSB has now been detected and/or established in 31 locations across southern Ontario, with no detections found in crops as of April 2015. This rapid spread and increased number of detections indicates that it is only a matter of time before BMSB moves onto host crops in Ontario.

This monitoring project is continued in the project titled, “Monitoring for brown marmorated stink bug in Ontario corn and soybean” (2015 – 2018).
