Start to consider winter annual weed burndown
Some of the most important considerations for wheat growers developing a weed-control plan include the wheat growth stage and soybean plant back restrictions for fields that will be double-cropped.
One option, Legleiter said, is to combine spring herbicide applications with topdressed nitrogen. Growers who go this route need to be sure to read herbicide labels.
“Many of the herbicide labels do allow for liquid nitrogen to be used as a carrier but might have differing adjuvant requirements and growth stage restrictions as compared to applying with a water carrier,” he said.
Legleiter also said the use of liquid nitrogen as a herbicide carrier also can mean increased risk of crop injury.
More information about spring herbicides and wheat can be found in a free, online article titled Spring Herbicide Applications on Winter Wheat. The article, written by Legleiter and Johnson, covers a number of herbicides, application timing, plant back restrictions and more.
