In order to evaluate the performance of some pesticides to control the two-spotted spider mite T. urticae, a test was performed in Americana, State of São Paulo, Brazil. The seven treatments were as follows: A) control; B) hexythiazox, 50g: C) hexythiazox, l00g; D) clofentezine, 150g; E) clofentezine, 250g; F) thuringiensin, 255g; G) clofentezine plus multimethyl alquenol (150g + 5.28g). Quantities above mentioned are of active ingredients per hectare (Table 1). Two days after the application, the best treatment was thuringiensin; after 08 days all treatments differed from the control and 15 days after the spray there was no significative difference among the treatments (Table 3).
