With the recent rains that we have got in Harvey County the past few weeks the weeds have begun to grow like crazy. This mixed in with the short and thin wheat stand is not a good combination.
It looks like some farmers might have to spray their fields before they start harvesting the wheat. There are several herbicide options producers can use as pre-harvest aids in wheat. There are differences in how quickly they act to control the weeds, the interval requirement between application and grain harvest, and the level or length of control achieved. All of them will require very good coverage to be effective, meaning a high gallonage spray volume should be used.
Here is a list of chemicals and rates you can use on your wheat to kill the weeds and grasses growing in it right now.
* Aim EC (1-2 oz)
* Dicamba (.5pt) + 2,4-D (.5 -1qt of 4lb/gal) -This has a 10-14 day waiting period before you can harvest after spraying
* Glyphosate (1 to 2 pt of 3lb ae/gal) + 2,4-D (1-2pt) -This has a 7 day waiting period before you can harvest after spraying
* Metsulfuron (.1 oz) + 2,4-D (0.5 to 2pt of 4 lb/gal) -This has a 10 day waiting period before you can harvest after spraying.
