There have been a few calls coming in with folks interested in spraying wild garlic (onions) in wheat.  The main concern is whether or not there is enough new growth on the wild garlic to obtain good control with Harmony Extra.  Harmony Extra is primarily taken up through the foliage.  Therefore new growth in the spring is essential to obtain good control.  The Harmony Extra label states that 2 to 4 inches of new growth from stressed weeds is essential for good control.  The mistake many make is to look for the new growth at the end of the garlic leaf.    The new growth actually comes from the bulb area and not from the end of the leaf.

There have been several calls about controlling Poa in wheat.  At this date Finesse Grass and Broadleaf or Osprey will provide some control depending upon the size of the Poa. If the Poa is large then these herbicides will probably not kill the weed but should hold it back enough for the wheat to outgrow it.

PB1580 Misprint. Misprint on Powerflex herbicide in the wheat section of the Tennessee Weed Control Manual PB1580.  The weed manual incorrectly states that MSO may be used as a substitute for NIS and AMS.  This is not correct.  Do not use MSO with Powerflex.
