One of the greatest threats to lost return and non-target plant damage in spraying is drift. Spray applicators have to be conscious of all kinds of factors that affect the risk of drift, including wind speed, boom height, potential inversions and, of course, spray quality.

Wolf also suggests which categories of quality (from Very Fine to Ultra Coarse) should rarely be considered in agricultural applications, and where spray applicators can find information to aid in one aspect of the crucial decision making process surrounding spraying.
