Abstract
A field trial was conducted for two consecutive years from 2007 to 2008 in kharif season at the Zonal Agricultural Research Station, Shimoga, Karnataka, under rainfed conditions with a popular hybrid DCH-32 against cotton pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechidae) with 13 insecticides/biopesticides alone or alternated with any one of these accounting to 11 treatments and a control. At initial stages, plant protection was given against sucking pests and other bollworms. Ninety days after germination, ETLbased sprays of these treatments were imposed after assessing 10% damage in fruiting bodies (squares, flowers and bolls). Among the treatments, significantly lower number of larval population/20 bolls was recorded in novaluron (4.15) and thiodicarb (4.35), whereas spinosad (12.31%) and thiodicarb (12.96%) recorded less green boll damage. With respect to yield and yield attributing parameters, spinosad (38.00) and indoxacarb (37.37) recorded maximum good opened bolls per plant. However, spinosad continued its supremacy by recording the lowest number of bad opened bolls, 5.60 per plant with minimum locule damage (14.20%). Significantly, maximum seed cotton yield was recorded in spinosad (2,123.06 kg/ha), followed by thiodicarb (2,012.77 kg/ha), emamectin benzoate (1,453.52 kg/ha), novaluron (1,908.82 kg/ha) and indoxacarb (1,891.58 kg/ha) than untreated control (475.00 kg/ha). The highest B/C ratio was recorded in thiodicarb (1:10.05), alternated with spray application of lamba cyhalothrin 5 EC-endosulfan 35 EC-chlorpyriphos 20 EC-thiodicarb 75 WP-thiodicarb 75 (1:9.83) and endosulfan (1:8.22). Interestingly, additional yield over control was high in spinosad (1,148.06 kg/ha), where the cost of additional treatment ( 14,716.79) was also high in this treatment.
