The two-spotted spider mite, Tetranychus urticae, is an economic threat to cotton acreage in Arkansas. Damage from this pest will likely increase with the implementation of the Boll Weevil Eradication Program in Southeast Arkansas. Frequent evaluation of the performance of commercial miticides is necessary for two-spotted spider mite suppression. Based on data from 1999 and 2000, Capture (0.06 lb ai/ac), Lorsban (1 lb ai/ac), and Zephyr
(0.0093 lb ai/ac) provided the most consistent and timely suppression of spider mites over the test period. Selective use of these miticides can prevent resistance and result in effective management of the two-spotted spider mite.
