Producers should pay close attention to the growth stage of their wheat before making spring herbicide applications. Some herbicides must be applied after tillering, several must be applied before jointing, and others can be applied through boot stage.
Too often producers do not notice mustard weeds in their wheat fields until the mustards start to bloom in the spring. To minimize yield losses, mustards should be controlled by late winter or very early spring, before the stems begin to elongate, or bolt.
As wheat growers evaluate their wheat stand, some may be considering replanting fields yet this fall. The fall of 2022 has been challenging for winter wheat establishment in Kansas and in the US Southern Great Plains. There are several factors to consider when deciding to replant wheat fields.
Mustard weeds in wheat fields often are not noticed until the they start to bloom in the spring. Mustards are much more difficult to control once they have flowered and often have already reduced wheat yields. To minimize yield losses, mustards should be controlled by late winter or very early spring.
