Clemson Agronomic and Vegetable Field Day highlights latest research/technology

Tarnished plant bugs and thrips are major insect pests for South Carolina cotton. But Clemson University researchers assure growers help is on the way. During the 2022 Agronomic and Vegetable Field Day at the Edisto Research and Education Center (REC)...

‘Dead man’s fingers’

Scientists work to get a handle on taproot decline A monster that lives by eating the dead is hiding underground, and it has developed a taste for soybeans. For the past two years, Arkansas Agricultural Experiment Station researchers have worked in...

SDS appearing in Missouri bean fields — keep records for future use

University of Missouri Extension agronomists reported during their weekly teleconference that sudden death syndrome is showing up in soybean fields across the state. MU Extension plant pathologist Kaitlyn Bissonnette says she is not surprised that the yield-robbing disease has reared...

Research: Diseases pack a big financial wallop

Economic losses due to soybean diseases in the United States from 1996 to 2016 amounted to more than $95 billion, according to a research team from Penn State's College of Agricultural Sciences who examined the long-term impact of soybean...

Soybean vein necrosis virus research leads to unexpected discovery

Sometimes, unexpected discoveries in the course of scientific investigation open new avenues of research. Virologist Ioannis Tzanetakis and doctoral student Jing Zhou used advanced genetic tools to identify and better understand the transmission of an orthotospovirus that causes vein necrosis...

New tool provides producers with impacts of diseases

Kentucky grain producers have a new, free tool at their disposal to see the past yield losses and economic impacts of common diseases affecting corn and soybeans. This tool can help them plan their disease management strategy for the...

A handful of diseases are popping up in late soybeans

• By Tom Allen • Soybean rust We don’t talk about soybean rust much as an issue, because it rarely has impacted yield. But with some late soybean acres in Mississippi, monitoring the disease this season might be important. To date,...
