Priorities

Category Rank Pest Type Pest Crop Stage Priority
Extension/Outreach 1 All 6- to 12-Inch Shoot University researchers, non-governmental organizations, consultants and producers are encouraged to work together closely with on-farm research and demonstrations. Producers recommended that a coalition between land grants, consultants, suppliers, dealers and registrants be developed to promote effective resistance management and pest management systems.
Extension/Outreach 1 Nematodes 6- to 12-Inch Shoot Soybean Cyst Nematode: There is the perception that up to 20% of ‘resistant varieties’ are really susceptible - researchers should seek to establish methods by which farmers may know if a “resistant” variety is really resistant.
Extension/Outreach 2 Nematodes 6- to 12-Inch Shoot Need to transfer research information to producers effectively, such as improving producer awareness of problems, different susceptibility of varieties, etc, as farmers currently depend on seed companies for this information.
Research 1 Nematodes 6- to 12-Inch Shoot Soybean Cyst Nematode: Producers indicated that development of alternative sources of resistance should be pursued, especially Chinese germplasm.
Research 1 Pathogens 6- to 12-Inch Shoot Sclerotinia Research: Researchers should develop a predictive model to alert producers when to control (with Topsin M) sclerotinia. This is especially needed with irrigated soybeans.
Research 1 Pathogens 6- to 12-Inch Shoot Sudden Death Syndrome Research: Researchers should evaluate soybean varieties for resistance to SDS.
Research 1 Pathogens 6- to 12-Inch Shoot White Mold Research: Accelerate research on resistant varieties and determine how plant architecture is related to resistance or disease severity.
Research 2 Nematodes 6- to 12-Inch Shoot Soybean Cyst Nematode: Resistant varieties are expected to lose their resistance so there is a need to keep currently registered products for control. However, in the North Central region, nematicides are not generally viewed as an essential pest management tool for SCN.
Research 2 Pathogens 6- to 12-Inch Shoot Sclerotinia Research: Coniothyrium minitans is an example of a promising biological control agent that is a potential alternative for control of S. sclerotiorum. Further research on this agent would be helpful.
Research 2 Pathogens 6- to 12-Inch Shoot Researchers are encouraged to develop predictive models to time white mold treatments (Topsin-M) more effectively.
Research 2 Pathogens 6- to 12-Inch Shoot Sudden Death Syndrome Research: Researcher should find ways to develop reliable assays to identify resistance to SDS.
Research 3 Nematodes 6- to 12-Inch Shoot Soybean Cyst Nematode: In the southern soybean belt, there is a strong need to keep nematicides registered due to the wider diversity of nematode populations.
Research 3 Pathogens 6- to 12-Inch Shoot Sclerotinia Research: Researchers need to investigate and develop more tools for control of resistance, i.e. how plant structure (large leaf vs. narrow leaf) affects severity.
Research 3 Pathogens 6- to 12-Inch Shoot Sudden Death Syndrome Research: Researchers are encouraged to incorporate SDS resistance genes in soybean genome.
Research 4 Nematodes 6- to 12-Inch Shoot Soybean Cyst Nematode: There is a need to continue support for, and refinement of screening methods to determine SCN resistance in soybean varieties.
Research 4 Pathogens 6- to 12-Inch Shoot Sclerotinia Research: Some current research is investigating mapping one or more genes that confer physiological resistance to S. sclerotiorum. Application of a biotech approach to control of sclerotinia would be very helpful.
Research 5 Nematodes 6- to 12-Inch Shoot Soybean Cyst Nematode: There is a need for new, quicker methods of identifying diversity in nematode populations to preempt future problems. The new “race”scheme is viewed positively but producers and seedsmen need information on its proper use and interpretation for making SCN management decisions.
Research 5 Pathogens 6- to 12-Inch Shoot Sclerotinia Research: Research is needed to investigate the efficacy of new dry bean and sunflower fungicides to see if they can be used on soybeans (other diseases such as downy mildew).
