Citrus rust mite control on orange trees with granular insecticides applied in the soil

Abstract

Granular insecticides used in the soil were evaluated for the control of the citrus rust mite, Phyttocoptruta oleivora, on orange trees. The application consisted of two parallel lines in the soil per tree. The treatments and the active ingredients per tree were as follows: A) etoprop, 8 g; B) carbosulfan, 4 g; C) isazophos, 7 g; D) carbosulfan, 2.5; E) fensulfothion, 20 g; F) fensulfothion, 12.5 g; G) check. Counts of the mites were made in laboratory at the day of application and 22, 36, 50, and 88 days after the application (Table 1). None of the granular pesticides gave positive results (Table 2).
