Abstract

In order to evaluate the performance of several chemicals to control the citrus leprosis mite on orange-trees a test was performed in Rio das Pedras, State of São Paulo, Brazil. The treatments were as follows: A) control; B) fenpropathrin, 13.5g; C) clofentezine, 20.0g; D) biphenthrin, 5.6g: E) binapacryl, 50.0g; F) flubenzimine 60,0g; G) ciexathin, 20.0g. The amounts above are in active ingredients per 100 liters of water. Each orange-tree received 4.0 liters of liquid (1332 liters/hectare). Seven evaluations of the mite infestation were made on fruits: the first, one day before and 02, 15, 30, 44, 65 and 79 days after spray. The best results were obtained in the treatments with ciexathin, binapacryl and biphenthrin.
