Citrazon (Ethyl O-benzoyl 3 chloro-2, 6-dimethoxy benzohydroximate) was compared with two orangotin acaricides Plictran and Vendex for mite control on apples and pears. Citrazon controlled the phytophagous European red mite, <i>Panonychus ulmi</i> (Koch) as effectively as Plictran and Vendex and all were low in toxicity to the phytoseiid mites <i>Typhlodromus occidentalis</i> Nesbitt and <i>T. columbiensis</i> Chant. Unlike Plictran and Vendex, Citrazon was much less toxic to another predatory mite, <i>Zetzellia mali</i> Ewing, and to the pear rust mite, <i>Epitrimerus pyri</i> (Nal.).References
