Ask an Agronomist

Answer: On the acres I work with, I try to spray all winter annuals (broadleaves and grasses) in the fall. Waiting until spring frequently means the weeds have gotten too big and already reduced the yield. Chickweed, peppergrass and most broadleaf weeds most likely emerge in the fall and can easily be controlled with a fall-applied product such as Harmony Extra. If you have garlic, it will likely require an additional spring application of Harmony Extra.

 

Little barley is best controlled with Maverick (see label and SIU research link below). Be sure to follow the instructions on the label regarding rotational restrictions going back to soybeans; it will require an STS bean for spring applications, due to carryover of the AI. Maverick will also control most of the broadleaf weeds, especially if the product is fall-applied.

 

 

Osprey is rated as good on little barley (see the link below). Be sure to follow the label recommendations with regard to waiting 21 days after the Osprey application before nitrogen is applied. Osprey is fairly good on most broadleaf weeds too.
