New tool can reveal cost of soybean cyst nematode

A profit calculator from the U.S. that works for Ontario fields determines the field-by-field impact

By
A new and free online tool can help growers estimate profit loss from soybean cyst nematode. The SCN Profit Checker calculator was developed by the SCN Coalition, a collective of researchers from colleges in nearly 30 U.S. states and the Ontario Ministry of Agriculture, Food and Rural Affairs. It’s designed to provide a clearer picture […] Read more

Nematode survey a valued benchmark opportunity

Project will target more than soybean cyst nematode

By
The word nematode is often linked to soybean cyst nematode (SCN), and with good reason. In North America, SCN accounts for annual losses of more than $1 billion and up to $50 million in Ontario. A survey of field and horticultural crops across the province seeks to update provincial nematode distribution maps and establish baseline […] Read more

Time to watch for tar spot, soybean cyst nematode

OMAFRA Field Crop Report for the week of June 26

By
Tar spot has now been established in the midwestern US for almost a decade and is an annual concern in many Midwestern states like Illinois, Indiana, Iowa, Michigan, and Wisconsin. While tar spot was not as yield-limiting in these areas in 2022, it continued to expand its range across the corn belt, as far west as Kansas […] Read more

Partnership to bring nematode resistance trait to Enlist E3 soybeans

By
Corteva Agriscience, BASF and MS Technologies announced they have entered into a mutually beneficial trait licensing agreement to develop next-generation Enlist E3 soybeans with the nematode resistant soybean (NRS) trait for farmers in the United States and Canada. As part of this agreement, Corteva and MS Technologies have licensed the Enlist E3 soybean trait to BASF for development with […] Read more

Assessing soybean performance

OMAFRA Field Crop Report for September 22

By
Soybean harvest has begun, and yields have generally been good. Many growers are reporting above average yields. But there are fields that underperformed. For those fields that yielded less than expected, it’s important to assess why in order to make good management decisions for the future. Sometimes we blame the weather or a specific variety […] Read more
Soybean cyst nematodes are easiest to distinguish from nodules based on their size, but can be confirmed with the yellow liquid inside when opened. The nematodes are identified by the red circle.

Soybean cyst nematode infected area continues to expand

Soybean’s biggest yield robber gaining resistance as trait effectiveness declines in some areas

By
Soybean cyst nematode (SCN) continues to migrate across Ontario and is adapting to resistant varieties. Albert Tenuta, field crop pathologist with OMAFRA, says SCN is showing up outside the traditional southwestern Ontario infection areas and into Huron, Bruce and Simcoe counties. Resistant varieties are beginning to show symptoms on the roots. Why it matters: Soybean […] Read more

Testing soil for soybean cyst nematode

OMAFRA Field Crop Report for September 17

By
Soybean harvest has begun, and many growers have asked if they could sample for soybean cyst nematode this fall. For many growers, managing soybean cyst nematode (SCN) means planting SCN resistance varieties BUT effective SCN management does not end when you have selected your soybean varieties! It is imperative to not only know your SCN […] Read more

Tar spot in corn and soybean cyst nematode

OMAFRA Field Crop Report for August 13

By
This week we would like to discuss tar spot in corn as well as soybean cyst nematode and sudden death syndrome in soybean. Tar spot in corn There is a lot of discussion and questions surrounding tar spot this year in Ontario. Tar spot is a new corn disease in the U.S. midwest and since […] Read more

Soybean cyst nematode confirmed in Manitoba

By
A damaging soybean pest that was expected to show up sooner or later in agricultural Manitoba has officially arrived. Crop surveys by University of Manitoba Ph.D. student Nazanin Ghavami with soil science professor Mario Tenuta and his students have turned up soybean cyst nematode at “extremely low” levels on soybean plant roots in one field […] Read more
