RESUMO
The effect of the systemic insecticide carbosulfan on the growth of pineapple, transplanted from in vitro cultures, was observed in a greenhouse experiment. Three doses of carbosulfan (10,25 and 50 ppm) were applied along with a control (no insecticide). the plants were harvested at 30, 60, 90, 120 and 150 days after being transplanted. The everage leaf length (ALL), average root length (ARL), shoot dry weight (SDW) and root dry weight (RDW) were assessed. Regression analysis did not show any significant difference between doses and days of development in what concerns ALL, but a positive effect of carbosulfan was observed in the evaluations of ARL, SDW and RDW, carried out at 120 and 150 days after the transplantation. The best results were obtained with the application of 25 ppm of carbosulfan.
