Pay attention to growth stage for spring herbicide decisions on wheat

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. The earliest practical and labelled applications generally result in the best weed control.

Wheat growth and development: Tool for estimating first hollow stem

Winter wheat is beginning to break dormancy, and the Kansas Mesonet has a tool to help track crop development. This tool provides the propability of first hollow stem occurrence for wheat varieties in Kansas. This is important for dual-purpose wheat growers because it is the optimal time for grazing termination to maximize forage yield while minimizing grain yield losses.
