Abstract

The investigations on efficacy of insecticides on pomegranate thrips was conducted at the Department of Entomology, College of Horticulture, Bagalkot, Karnataka during the year 2015-16. Thrips injury leads to leaf tip turn brown and get curled, drying and shedding of flowers and scab on fruits which will reduce the market value. Among the different insecticides evaluated against thrips on pomegranate, cyazypyr 10 OD @ 1.5 ml/l of water recorded significantly highest fruit yield (15.17 t/ha) and lowest fruit damage (6.22%) followed by imidacloprid 17.8 SL @0.3ml/l (14.67 t/ha and 9.65%, respectively). The next best treatments were, clothianidin 50 WDG @ 0.17 g/l and diafenthiuron 50 WP @ 1.0 g/l. So, spraying of cyazypyr 10 OD (a new anthranilicdiamide insecticide) @ 1.5 ml/l recorded highest net returns of Rs. 6,63,000 per ha followed by imidacloprid 17.8 SL @ 0.3 ml (Rs. 6,29,648/ha). However, in terms of benefit cost ratio, imidacloprid 17.8 SL proved best (3.77) followed cyazypyr 10 OD (3.62). Hence, spraying of imidacloprid 17.8 SL @ 0.3 ml or cyazypyr 10 OD @ 1.5 ml may be recommended for the effective management of thrips on pomegranate.

Conclusion

The study can be conclude that, among the different insecticides evaluated against thrips on pomegranate, cyazypyr 10 OD @ 1.5 ml/l of water recorded significantly highest fruit yield (15.17 t/ha) and lowest fruit damage (6.22%) followed by imidacloprid 17.8 SL @ 0.3ml/l (14.67 t/ha and 9.65%, respectively). The next best treatments were, clothianidin 50 WDG @ 0.17 g/l and diafenthiuron 50 WP @ 1.0 g/l. So, spraying of cyazypyr 10 OD (a new anthranilicdiamide insecticide) @ 1.5 ml/l recorded highest net returns of Rs. 6,63,000 per ha followed by imidacloprid 17.8 SL @ 0.3 ml (Rs. 6,29,648/ha). However, in terms of benefit cost ratio, imidacloprid 17.8 SL proved best (3.77) followed cyazypyr 10 OD (3.62). Hence, spraying of imidacloprid 17.8 SL @ 0.3 ml or cyazypyr 10 OD @ 1.5 ml may be recommended for the effective management of thrips on pomegranate.
