Field Performance of Pyridalyl 10 EC (S1812) Against Diamond Back Moth, Plutella xylostella L. (Lepidoptera; Yponomeutidae) on Cabbage

A. Suganthi, R. Jayakumar and S. Kuttalam

Abstract

Pyridalyl 10 EC was tested at the rate of 50, 75 and 100 g a.i. ha-1 against diamond back moth, Plutella xylostella on cabbage. Endosulfan 35EC at the rate of 700 g a.i. ha-1 and Indoxacarb 14.5 SC at the rate of 30 g a.i. ha-1 were kept as standard check for comparison. All the treated plots showed significant reduction of pest population. After three sprays, the mean larval population was significantly lower in plots treated with pyridalyl at 75 (1.60 and 1.67 larvae plant-1) and 100 (1.50 and 1.53 larvae plant-1) g a.i ha-1, during first and second season, respectively. Yields obtained from the pyridalyl plots compared favorably with the indoxacarb and endosulfan plots. During both the season trials, pyridalyl at the rate of 75 g a.i ha-1 (77.2 and 76.24 t ha-1) and 100 g a.i ha-1 (79.0 and 78.20 t ha-1) registered significantly higher yields when compared to other treatments.
