Due to the rapid increase in the incidence of citrus variegated chlorosis (CVC) in the State of São Paulo and the involvement of sucking insects such as sharpshooters in its transmission, an experiment was conducted to evaluate the efficiency of new chemical products for controlling the vector. Three different formulations of the systemic insecticide acetamiprid were used at different doses (1, 2, and 4 mL/plant), and compared to a single dose (3 mL/plant) of Winner (imidacroprid). Considering the feeding behavior of the vector, the treatments were applied onto the bark of the trees using a paintbrush. Forty-four plots, each composed of a single 18-month-old plant, were used in the experiment. The treatments were applied on 4 newly formed shoots on each plant. The evaluations were made 20, 26, 37, 45, 52, and 62 days after the product was applied to the branches. After each evaluation, the old sharpshooters were replaced by new ones. Satisfactory efficiency of all treatments was observed 26 days after the applications and remained like that until the 52nd day. None of the treatments showed toxicity effects except for Convence B.
