Potential of Diamond Insecticide for Lygus Management in the Texas High Plains

The insect growth regulator Diamond alone and in tank mixes was evaluated for its efficacy towards Lygus hesperus.  Efficacy was acceptable at a rate of 9 fl-oz/acre or higher, or when tanked mixed at 6 fl-oz/acre with Carbine at 1.7 oz/acre or Acephate at 0.75 lbs/acre.  Carbine alone at 1.7 fl-oz (a low use rate) did not perform well.  Treatments of Acephate alone or with Diamond were the most efficacious treatments.  Yield data was not available at time of abstract submission.
