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. |

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. |

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. |

Soybean Cyst Nematode: Producers indicated that development of alternative sources of resistance should be
pursued, especially Chinese germplasm. |

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. |

White Mold Research: Accelerate research on resistant varieties and determine how plant architecture is related
to resistance or disease severity. |

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. |

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. |

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. |

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. |

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. |

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. |

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). |
