Control of Pseudoplusia includens (Walker, 1857) in the soybean culture with different insecticides

Abstract

The aim of this research was to test the efficacy of different insecticides, and dosage against Pseudoplusia includens in the soybean culture. The treatments were: (1) alphacypermethrin + teflubenzuron, (2) teflubenzuron, (3) diflubenzuron and (4) profenophos + lufenuron, in different doses. All the insecticides tested in this research presented high efficacy on the control of Pseudoplusia includens in the soybean culture. These insecticides and dosages were: (1) mixture of alphacypermethrin and teflubenzuron at dosages from 9.0 to 11.25 g a.i.ha-1, (2) teflubenzuron at dosage from 6 to 12 g a.i.ha-1, (3) diflubenzuron at dosage from 10 to 20 g a.i.ha-1 and (4) the mixture profenophos and lufenuron at dosage 75.0 and 7.5 g a.i.ha-1, respectively. All these insecticides after 15 days of application promote 100% dead caterpillars. None these insecticides decrease soybean yield.
