Two spraying experiments were carried out at the Ribeirão Prêto Agr. Exp. Sta. aiming at the control of insect pests and mites that affect the bean crop. Endrim and Diazinon gave good insect and mite control and increased the yields significantly when compared with the controls in the first trial. In the second test the systemic pesticides, Sistox and Metasistox gave the best insect and mite control and the highest yields.
