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…]
