Abstract/Contents:Presents a study conducted between 1992 and 2011 to "provide a better understanding of the optimal use of presently available insecticides and to delineate effective alternatives to the overused pyrethroids" on annual bluegrass weevils. Details the methods and materials used in the study, noting that data has been sorted into three application intervals, with trials conducted using 14 different single-ingredient products against pyrethroid-susceptible populations. Discusses that among pyrethroid-susceptible populations, "pyrethroids still tend to be the most effective...if they are applied as adulticides." Notes that effective alternatives include Acelepryn, Conserve, chlorpyrifos, and Dylox when applied as a larvacide. Reports that among pyrethroid-susceptible populations using multiple-ingredients, Aloft and Allectus were used, although "Aloft provides only the same control rates as bifenthrin alone, and Allectus was even less effective." Comments that many combinations were tested fewer than three times, and were thus omitted from discussion. Explains that regarding pyrethroid-resistant populations, "data available are so limited that we combined data from applications intervals if there seemed to be no significant difference." Concludes that "optimizing application timing and techniques to essential to improving insecticide performance," and "using pesticides only when and where necessary is the key to reducing the selection pressure toward the development of insecticide-resistant populations."
