IPM Message for Cranberry Growers: Jun 9, 2016

Jun 9, 2016

Just a clarification: Delegate and Altacor are still the best choices for Spag.  We had heard of a report where Spag were not well controlled with a Delegate application and we were speculating that it may have been due to the size of the larvae. Further information may be indicating that the application may not have been up to par. We certainly did not mean to infer that these insecticides were not good choices.  The insecticides perform better against smaller larvae and those should be your primary targets.

If treating with Altacor, Confirm or Intrepid, apply early in the moth flight (3 weeks after moth flight BEGINS).  When using Delegate, the recommended timing is 10-14 days after PEAK moth flight.
