‘Spray And Wait’ Is Critical To Tackling Green Bridge Pathogens

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.

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.

Emerging Use Of Drones May Change Face Of No-Tilling

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.

Try An ‘Attitude Adjustment’ To Boost Soybean Yields

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.

Key Wheat Pathogen Genome Sequenced

June 17, 2011 | Posted in Crop Protection, Nutrient Management

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.
