Bioefficacy of Flubendiamide 480 SC against American bollworm in Cotton and Biochemical changes

Two field trials were conducted to evaluate the bioefficacy of flubendiamide 480 SC in cotton against Helicoverpa armigera. Flubendiamide 60 g a.i. ha⁻¹ showed marked reduction in the larval population and recorded up to 96.0% reduction in damage. Four biochemical parameters viz., total sugar, amino acids, protein and phenol content in cotton seeds were studied in relation to the biochemical changes due to flubendiamide application. The total sugar content was significantly increased when the plants were treated with flubendiamide 60 g a.i. ha⁻¹ and there was no significant difference in amino acid, protein and phenol contents due to flubendiamide application.
