The concept of integrated pest management (IPM) has received widespread acceptance only within the past decade. Evidence of this is reflected in the increased number of articles dealing with pest management being published in scientific journals, and the increased number of papers presented at various scientific meetings. However, it is not all that new. A version of the IPM called supervised control was being practiced in alfalfa and cotton in California over 30 years ago and a sophisticated cotton insect scouting program was being used in Arkansas in the 1950s. Though these early programs were aimed at insect control, they demonstrated the advantages of extensive monitoring, which is the backbone of any pest management program.

Japanese plum (Prunus salicina Lindel. `Casselman') trees exposed to three atmospheric ozone partial pressure treatments were sprayed with a summer application of Volck Supreme oil (1% aqueous solution) to control an outbreak of spider mites (Tetranychus spp.). Phytotoxic effects were observed on the foliage of trees in the plots exposed to ambient or higher atmospheric ozone partial pressures 5 days following spray application. Foliage on trees exposed to 0.044 and 0.081 μPa·Pa-1 ozone [12-h mean (8 Apr. to 12 June 1992)] partial pressures developed water spotting and more foliage abscission than trees exposed to charcoal-filtered air (0.024 μPa·Pa-1 ozone). Thus, ozone air-pollution stress may predispose plants to increased phytotoxicity from summer oils.
