Many field observations have caused speculation by both growers and researchers regarding the coincidence of higher spider mite populations on plants with foliage covered with fine road dust. This association occurs more commonly near roads or avenues which are heavily traveled. These investigations indicated that road dust alone did not stimulate or affect the mites in a manner which might result in higher populations.
