Insecticide Efficacy and Application Timing for Blue Alfalfa Aphid Control, 2014

Abstract

The objective of the study was to evaluate the efficacy of the insecticidal compounds via ground spray applications at various times for control of BAA on alfalfa grown for hay production under low desert growing conditions. A field study was conducted during the spring of 2014 at the UC Desert Research and Extension Center. A stand of alfalfa, VAR. ‘CUF-101,’ was used for the experiment. The experimental design was an RCB using four replicates with 10 insecticidal treatments and an untreated check. Plots measured 13.33 ft by 50 ft and insecticide treatments …
