Weed management may be one way to cut back on the fertilizer bill. Syngenta product lead Shawn Hock says weeds take up a lot of nitrogen. “In recent studies that we’ve done with two-to-four inch weeds across a lot of different sites and found in today’s economic conditions they can use $24 an acre of fertilizer that was intended for the crop,” said Hock. “To battle that, get your herbicides on a little earlier than normal, increase the rate and use multi-effective site-of-action herbicides to combat the weeds and keep the investment with the crop and not the weeds.” Hock says there are options for farmers dealing with the glyphosate shortage. “Spray glyphosate when you need to and not because you can and overlap residuals.”
