A field test was carried out to evaluate the performance of several pesticides for the control of the citrus leprosis mite Brevipalpus phoenicis. The treatments were as follows: A) propargite (0.05; 72% EC) + sulphur (1,0; 75% CS); B) peropal (0.1 kg 25% MP); C) quinomethionate (0.05 kg 70% MP) (standard treatment); D) dicofol + tetradifon (0.2; (16% + 6%) EC; E) propargite (0.075; 72% EC); F) check. The quantities of the products employed in the experiment were based on the commercial formulations for 100 liters of water. Each orange-tree received a single application of ten liters of spray. Five mite evaluations were made: 4 days before spray and 16, 31, 45 and 60 days after the application. All treatments resulted in real pest reduction, higher than 80%, except for A (16 days after the spray) and for treatment C (60 days after the application).
