Description: The success of an operational or pilot insecticide spraying program against the spruce budworm (Choristoneura fumiferana Clemens) depends to a great extent on a variety of factors, and, in particular on: spraying efficacy and the meteorological conditions during and immediately following spraying. Among other things, spraying efficacy depends on: knowledge of the volume of insecticide necessary to kill this insect (droplet imbibing assays); adjustments to the spraying system in order to produce droplets containing a lethal dose (AT-802 calibration); and, finally, the capacity to achieve target objectives (optimization trials)?that is, the deposit of these droplets on foliage.
