Abstract:
The experiments were conducted during Rabi seasons of 2020-21 and 2021-22 on research farm of Department of Agricultural Entomology, College of agriculture, V.N.M.K.V. Parbhani. The Seed treatment with Imidacloprid 48 FS and thiamethoxam 30 FS was done before sowing and soil drenching of clothianidin 50 WDG was done at 15 days after sowing as per the treatment. The first spray of insecticides was applied on appearance of sufficient population of safflower aphid while second spray was given at an interval of 15 days as per the treatment. All the treatments were significantly superior over untreated control.
The experiments were conducted during Rabi seasons of 2020-21 and 2021-22 on research farm of Department of Agricultural Entomology, College of agriculture, V.N.M.K.V. Parbhani. The Seed treatment with Imidacloprid 48 FS and thiamethoxam 30 FS was done before sowing and soil drenching of clothianidin 50 WDG was done at 15 days after sowing as per the treatment. The first spray of insecticides was applied on appearance of sufficient population of safflower aphid while second spray was given at an interval of 15 days as per the treatment. All the treatments were significantly superior over untreated control.
The minimum overall mean number of aphid population/5 cm apical shoot length/plant was recorded in the treatment with two foliar sprays of spinetoram 11.70 SC @ 420ml/ha (9.93 aphids/ 5 cm apical shoot length/plant) which was at par with the treatment with two foliar sprays of Cyantraniliprole 10.26 OD @ 900ml/ha (11.22 aphids/ 5cm apical shoot length/plant). The next better treatment in order of efficacy were seed treatment with thiamethoxam 30 FS @ 10ml/kg seed & one foliar spray of spinetoram11.70 SC @ 420ml/ha and seed treatment with thiamethoxam 30 FS @ 10ml/kg seed & one foliar spray of Cyantraniliprole 10.26 OD @ 900ml/ha which were at par with each other by recording 15.08 and 17.35 aphids/ 5cm apical shoot length/plant, respectively. In an untreated control, higher population of 181.13 aphids/ 5cm apical shoot length/plant was recorded. The treatment with two foliar sprays of spinetoram 11.70 SC @ 420ml/ha was recorded highest seed yield of 14.63 q/ha which was at par with the treatment with two foliar sprays of Cyantraniliprole 10.26 OD @ 900ml/ha (14.24q/ha). The treatments with two foliar sprays of spinetoram 11.70 SC @ 420ml/ha and the treatment with two foliar sprays of Cyantraniliprole 10.26 OD @ 900 ml/ha recorded the ICBR of 1: 3.64 and 1: 2.30, respectively.
