Populations of winter annual weeds will become more prevalent in late March/early April and can compete with wheat and barley and slow the rate of crop development potentially reducing yield. If winter annual weeds like common chickweed, henbit, purple deadnettle, marestail/horseweed, and others emerge with the small grain and are left unchecked, the potential impact on yield could be great.

Certain herbicides can be applied in different nitrogen fertilizer carriers, but timing is critical. Article written by Dwight Lingenfelter with Penn State University.
