Evaluation of the efficacy and residual activity of Chlorantraniliprole 600 g/L SC against fall armyworm Spodoptera frugiperda (J.E. Smith,1797) (Lepidoptera: Noctuidae) on Corn (Zea mays Linnaus, 1753)
Abstract
The fall armyworm, Spodoptera frugiperda (J.E. Smith,1797), (Lepidoptera: Noctuidae) is a polyphagous pest that has a worldwide distribution. It is an invasive species and can cause significant damage to corn. In this study, the effectiveness of four doses (2, 3, 4, and 5 ml/da) of Chlorantraniliprole 600 g/l against S. frugiperda was first investigated. Then, the residue amount of 5ml/da dose of Chlorantraniliprole 600 g/l was determined. Efficacy trials were conducted in arable fields in Adana and Şanlıurfa provinces from August to September 2023 according to the randomized block design with five characters (four doses of the trial insecticide and control) and four replications. Residue experiments were carried out in Adana and Şanlıurfa provinces. When the seventh day counts were evaluated, mortality from the 2 ml/da dose was between 39.67 and 38.84%; mortality from the 3 ml/da dose was between 56.68 and 57.53%; mortality from the 4 ml/da dose was between 75.05 and 77.22%; and mortality from the 5 ml/da dose was between 93.96 and 93.86%. As a result of the sampling, the residue amount of Chlorantraniliprole in corn was found to be below the residue limit determined in Türkiye and Europe. It was concluded that a dose of 5 ml/da of Chlorantraniliprole 600 g/l can be used as an effective dose against S. frugiperda.
