Abstract:
Two formulations of the insecticide active ingredient cyfluthrin (Baythroid® 2, Renounce® 20WP) were compared for fall alfalfa insect control, as was a lower active ingredient rate of both chemistries that included dimethoate. Differences in formulation effects of cyfluthrin were noted for cowpea aphids, spotted alfalfa aphids and alfalfa caterpillars at one day post treatment. At four days post treatment formulation significant differences were evident for numbers of bigeyed bugs, while at seven days after application formulations differed in numbers of spotted alfalfa aphids. Usage of dimethoate with a lower rate of cyfluthin resulted in less control of threecornered alfalfa hoppers throughout the study, improved initial control of spotted alfalfa aphids and clover leafhoppers, an increase in leafminer flies at four days post treatment and reductions in numbers of bigeyed bugs and spiders on this sample date, as well as significant reductions of lygus bugs later in the study compared with cyfluthrin only treatments.
