ABSTRACT
The efficiency of Actara Mix 110 + 220 CE (thiamethoxan + cipermetrina) was evaluated in the field at different concentrations, against phytophagous pentatomidae on soybeans. A completely randomized block with 5 replications was used, each plot with ten rows of plants of cv, Liderança. Treatments were: a) Actara Mix (200 mL p.c./ha ); b) Actara Mix (200 mL p.c./ha + 5g of salt); c) Actara Mix (100 mL p.c./ha + 5 g of salt ); d) Endosulfan (1,000 mL p.c./ha); e) Endosulfan (500 mL p.c./ha + 5 g of salt); f)Control (without treatments). Four evaluations were made of the of occurrence of nymphs and adult stages of the species:Nezara viridula, Piezodorus guildinii and Eushistus heros; before pulverization, and 2, 7 and 15 days after application. Evaluations showed that the pesticide dose of 200 mL was efficient in the control of N. viridula and P. guildini, and in the dose of 100 mL with 0.5 g of salt in the control of N.viridula.
