When a farmer uses a pesticide against a pest, weed, or pathogen, s/he is essentially conducting a field-scale micro-evolution project.
While there are dozens of common weeds that threaten yield each season, many Midwest farmers who grow corn or soybeans are facing off with waterhemp now. “New cases of resistant waterhemp are daunting to those of us in the ag industry because it threatens the already-delicate ROI ratio,” says Dave Roome, customer technical specialist, Corteva […]
With the increase in wet weather this spring, the Delaware Department of Agriculture has issued a warning to producers to not let their livestock fill up on buttercups. The bright yellow flower may look pretty across pastures, but it can be toxic to livestock and horses that ingest it. According to the Kentucky Equine Research, […]
Glyphosate-resistant Palmer amaranth, one of the most threatening weeds in Southern corn and soybean fields, is spreading into the Midwest, warns Syngenta. Palmer amaranth, a member of the amaranthus (pigweed) family, has a complex lifecycle. The combination of its ability to develop resistance and its extended emergence period makes it especially difficult to control. Known […]
In the battle against herbicide-resistant weeds, university and industry research is rewriting some of the “rules” for managing resistant weeds. Syngenta, along with a university research team, suggests these key strategies for managing herbicide-resistant weeds: Use multiple, effective modes of action (MOAs) every year — ideally, in every herbicide application. A University of Illinois study […]
Robotic weeders come to a farm near you in the future? Maybe. The growing popularity of robotic weeders for specialty crops has grown partly out of necessity, says Steven Fennimore, an extension specialist at the University of California, Davis. The need for robotic weeders stems from two issues. One is a lack of herbicides available […]
