Abstract

A grasshopper control study was conducted to evaluate the effectiveness of a new class of systemic chemical. The new pesticide Prevathon® (high and low levels) was compared to Coragen®, Dimilin®, and a nontreated check. Grasshoppers were numerically reduced the most by Coragen and Prevathon, though not significant. The highest level of Prevathon did not numerically impact beneficial insects in general. Biomass and forage quality were not significantly impacted by chemical treatment. However, forage biomass was numericallygreatest for the highest level of Prevathon. Prevathon appears to be an acceptable systemic pesticide for grasshopper control with minimal impacton other insects.
