Chemical control test of the citrus leprosis mite Brevipalpus phoenicis (Geijskes, 1939) on orange trees

Abstract

This paper deals with chemical control of the citrus leprosis mite on nature orange trees. The test was carried out in Tietê, State of São Paulo, Brazil (november 1985 - january 1986). The seven treatments were evaluated using plots, with four repetitions (three plants per repetition). Treatments were as follows: A) cyhexatin; B) cyhexatin; C) quinometionate; D) flubenzimine; E) clofentezine; F) clofentezine; G) bromopropilate; H) check. Table 1 shows the pesticides, doses, formulations and the material used in 100 liters of water and per hectare. Counts of the mite were made on fruits 01 day before and 07, 20, 34 and 58 days after the application (table 2). The most efficient treatments after 58 days of the spray were obtained with bromopropilate, clofentezine (20 g/ha), and flubenzimine (Tables 3 and 4).
