Choosing a winter barley seed treatment

VIBRANCE Duo now has registration for use as a seed treatment for winter barley

For the control of seed-borne Microdochium seedling blight, covered smut and moderate control of leaf stripe. As in wheat, the VIBRANCE effect can also be seen in barley: VIBRANCE Duo has excellent establishment and rooting benefits.

Summary of VIBRANCE DUO activity in barley

# = Loose smut control is not claimed on the VIBRANCE Duo label but trials have shown Sedaxane to have good activity. In higher risk loose smut situations Syngenta recommend co-application with a loose smut active partner, such as Rancona I-MIX.

When is the risk of Loose smut higher?

• Untested or loose smut infected farm saved seed.

• When planning to farm save your seed.
