Insecticide spray drift can damage beneficial insect populations especially bees and natural predators of Montana agricultural pests. Drift is also costly from a financial standpoint. If only 50 percent of an applied solution makes it to the target, then you have wasted 50 percent of what you have applied.

Sadly, the majority of pesticide spray drift problems involve mistakes that could have been avoided by the applicator.
