During the past several years we have prepared and tested for pesticidal activity numerous 2-aryl-1, 3-indandiones. Although certain compounds in this class have been known as anticoagulants (Bruynes 1968) and anti-inflammatory agents (Lombardino and Wiseman 1968), we have discovered that other specific members, which possess little or no anticoagulant activity, show an unexpected degree of toxicity to the twospotted spider mite, Tetranychus urticae Koch, and their eggs. When the latter indandiones were tested in the field against the same mite strain their control was only marginal. It was reasoned that the poor performance of these compounds under field conditions might be related to their insoluble nature and that modification of their partitioning properties might lead to enhanced acaricidal activity. To accomplish this objective, various enol esters were prepared for testing. Reported here are certain aspeets of the acaricidal properties of this type of compound.
