| Abstract | ||
| Soybeans stand out among the main crops of world economic interest, Brazil being one of the main producing and exporting countries. Thus, this work aimed to evaluate the efficiency of insecticides used alone and with the addition of adjuvant formulas based on orange oil and nanoparticulated sulfur (Oro Solve®) in the control of the neotropical brown stink bug in soybean. The experiment was carried out at the Experimental Farm of the State University of Maringá – UEM, located in the city of Umuarama – PR. Samples were collected and periodically evaluated at predetermined intervals: an analysis prior to application and analysis was performed at 1, 3, 5 and 10 days after application. On the 10th day after the beginning of the experiment, a new application was performed, with subsequent evaluations 1 and 3 days after reapplication. In the evaluations, the number of stink bugs found per sampling and the efficiency of control in each treatment was noted. It was evaluated by manual harvesting of 1.0 meters in three lines of the useful area of each plot, with a posterior trail, using a stationary trail. After weighment, the grains or values were transformed to kg.ha-1, using the correction of recovery for the water content of 13%. Neotropical brown stink bug occurrence data, insecticide and mixtures evaluation, as well as soybean yield, were subjected to analysis of variance by the F test, and the means compared by the Duncan and Tukey test (P≤0.05), respectively. The insecticides based on acephate (Perito®), imidacloprid + bifenthrin (Galil®) and bifenthrin + carbosulfan (Talisman®) in addition to Oro Solve® were found to show greater bedbug control efficiency. There was a greater extension of the effective control period in the treatments that had adjuvant addition. The application to the tests that were sprayed with insecticides in addition to Oro Solve®, and the insecticides used alone were used, but they all differed from the control and the percentage increase was always higher in the tests containing the mixture with Oro Solve®. | ||
