The soil pathogen analysis process is based on polymerase chain reaction (PCR) tests that are very specific and sensitive and only possible in a laboratory.
While green bridge is a major disease worry in the Pacific Northwest, it’s a problem Midwestern no-tillers should be leery of with certain crop rotations and cover crops.
Some plant pathologists maintain green bridge is not likely to be a disease concern with the traditional Midwestern corn-and-soybean rotation. But with the expanding growth of cover crops and adoption of other crop rotations, it’s a possible disease worry for Corn Belt no-tillers.
Researchers at Iowa State University have generated a draft genome sequence of Fusarium virguliforme, a pathogen that causes sudden death syndrome (SDS) in soybeans.

There were multiple reports of Sudden Death Syndrome (SDS) in soybeans this past year. The cooler, wet season helped promote the disease in susceptible varieties, but the presence of soybean cyst nematode (SCN) can also increase the effect of SDS.
Crop scouting, 3-D mapping, spot spraying and pathogen detection all could be performed by unmanned aerial vehicles to cut labor and input costs and improve decision making.
In the not-so-distant future, farmers wanting to scout fields for diseases and pests, spot spray for weeds or obtain 3-D maps of their farm ground will be turning to tiny autonomous helicopters or planes to do the job.
No-tillers should plant earlier, control weeds better and capitalize on seed-treatment technology to get the most out of every plant, a soybean specialist says.
When soybean prices were hovering around $5 a bushel several years ago, farmers could justify their decision to plant, fertilize and spray their corn crop first.

University of Illinois researchers identified the top pathogens, pests, and weeds affecting soybean production in a recent article in the journal Food Security.
A U.S. Department of Agriculture (USDA)-led consortium of scientists has fully sequenced the genome of the pathogen that causes the wheat disease known as septoria tritici blotch, which can cause significant yield losses.
