Pre-harvest herbicide applications may be needed in wheat fields that have a lot of weed growth due to the recent wet weather patterns.  These herbicide applications address several issues such as harvest difficulties, dockage problems, weed seed production, and soil water depletion. Although it may not be possible to recover lost yield potential due to weed interference, a pre-harvest treatment can go a long way toward reducing weed problems in future years by preventing the production and spread of weed seed. Herbicides labeled for use as harvest aids in wheat are listed in Table 1. There are differences in how quickly they act to control target weeds, the interval requirement between application and grain harvest, and the level or length of control achieved. All of these herbicide treatments will require thorough spray coverage to be most effective and can be used once wheat reaches the hard dough stage, which is[Read More…]

With harvest season right around the corner, now is the time to start making plans for the control of winter annual weeds, including marestail.  When harvest and post-harvest conditions allow, fall is the best time to control many of these weeds.  This is because the weeds are a lot smaller in the fall, and our fall weather tends to be consistently warmer and drier than our variable cool and wet springs.  With fall-applied herbicide season upon us, we wanted to provide a few application tips to those who are planning on making fall herbicide applications: Scout fields and determine whether you need an application. Not all fields need an application; however, if you pull back the crop residue after harvest, especially in corn fields, you are likely to find infestations of winter annual weeds.  Scouting fields should begin soon after a field is harvested, with special attention paid to fields[Read More…]

In last week’s article we discussed the herbicide shortage for the 2022 growing season and outlined a couple of scenarios where we can switch to alternative herbicides to accomplish the same weed control objectives.
