USGA Summary Points:Both surfactants (Silwet, Helena Chemical Co.) and PDSOs (Civitas, Suncor Energy Inc.) can cause moderate to high adult mortality. Mortality was observed shortly after application (< 3 hrs), with most mortality occurring within 24 hrs. Neither products reduced larvae in the greenhouse or field. Phytotoxicity was observed with Silwet at 9 oz./M and thus it was abandoned from future field studies. Moisture level significantly affected Civitas and Silwet efficacy in the laboratory. However, manipulating soil moisture in the field through pre- and post-irrigation and/or altering carrier volume did not improve adult control. No differences in susceptibility to surfactants or PDSOs were detected between pyrethroid resistant and susceptible populations. Civitas rate has not been a significant factor in field trials. Split or sequential applications in back-to-back weeks has provided the greatest reductions of adults and their future developmental stages.
