Summary

​Knowledge of the current efficacy of insecticides on common pests is critical to growers. Insecticide resistance causes efficacy to decrease, so monitoring for resistance is beneficial. With insect growth regulators, the cause of observed efficacy is not always obvious. By understanding the impact of insecticides, growers can choose insecticide products and application times wisely. This presentation shows insecticide resistance monitoring data from 2017 and 2018 for several insecticides on soybean looper and tarnished plant bug. It then shows data evaluating the impacts of Diamond (novaluron) on tarnished plant bug adults. These data help explain why Diamond often works well even when applied before nymphs are present.
