Since 2011 we have seen a decline in efficacy of thiamethoxam treated cotton seed against tobacco thrips. This has led to the increase of foliar applications in mid-south cotton acres.  Recently Syngenta has confirmed that populations in the mid-south region are in fact resistant to the active ingredient thiamethoxam. This is specific to tobacco thrips and does appear at this time to be confined to only the mid-south region. Resistance appears to be specific to thiamethoxam and not present in the active imidacloprid.

We will be provide much more information as it becomes available at fall and spring meetings.

The following links by Gus Lorenz and Scott Stewart provide additional information.
