MOTTA, R. et al. Spray of new acaricides against the mite of leprosis Brevipalpus phoenicis (GEIJSKES, 1939) (Acari: Tenuipalpidae) on citrus. An. Esc. Super. Agric. Luiz de Queiroz [online]. 1987, vol.44, n.1, pp.811-824. ISSN 0071-1276. http://dx.doi.org/10.1590/S0071-12761987000100042.
In order to control the citrus mite of leprosis, orange trees were sprayed. The following treatments and quantities of active ingredients per hectare were sprayed: A - check; B - hexythiazox, 59. 4g; C - hexythiazox, 89.1g; D - hexythiazox, 118.8 g; E - hexythiazox, 59.4 g+cyhexatin, 123.75g; F-bromopropilate, 371.25g. Each tree received in coverage 3.33 liters of water plus pesticide. Eight evaluations were made on ripe fruits using stereo microscopes: one (02 days before the spray) and 7 post-treatments (05, 12, 25, 40, 54, 67 and 89 days after the application). The results indicated efficient control of all treatments on citrus mite of leprosis in the period between 25 and 89 days after the spray. Table III shows the real mortality (efficiency) and Table IV the statistical analysis.
