Research could lead to herbicide resistance solution

One by one, weed species are becoming resistant to popular herbicides. Unfortunately for farmers, agricultural chemical manufacturers say they don’t have any new products in the pipeline to replace those that are gradually outliving their usefulness. That could change in the years ahead, however. Researchers at Monsanto are working on technology that could allow farmers

Say what?!? July polar vortex on the way; could affect crops

Don’t look now, but the polar vortex is coming back. And, yes, we’re talking about the middle of the summer. It won’t be bitterly cold as in January, when a large sub-zero Artic air mass held much of the eastern United States in its grip for weeks. Still, this polar invasion will bring temperatures to

Play it safe when handling, applying pesticides

When working with something as toxic as pesticides, you can never be reminded enough about how dangerous they are if not used properly. That includes the risks to farmers themselves. Andy Bauer, an Ohio State University Extension agricultural health and safety expert, said farmers can avoid injury applying farm chemicals if they follow product label

Fungicide/herbicide mix usually unnecessary on tillering wheat

Fungicide applied along with herbicides on tillering wheat might give a farmer greater peace of mind but it isn’t likely to increase yields, according to research by South Dakota State University. While not a costly input, fungicides often are unnecessary on tillering wheat because the crop usually is under little disease pressure at that growth

Hose drops could hold a key to preventing bee deaths

Farmers and custom applicators can do their part to protect bees from exposure to pesticides by fitting their booms with hose drops. Research conducted on oilseed rape crops at the University of Hohenheim in Germany found that using the spray nozzle attachments, also known as dropleg devices, can nearly eliminate spray drift. Researchers also found

Trimble’s GreenSeeker assesses crop health, nitrogen needs

A hand-held device that measures nitrogen levels of field crops could come in handy this spring, should fertilizer be in short supply in the United States. The GreenSeeker crop sensor, manufactured by Trimble Navigation, uses red and infrared light to evaluate general crop health. Farmers can enter the sensor’s digital reading into an online nitrogen
