Abstract:
An investigation was carried out under field conditions during Kharif 2018-19 to 2020-21 at Oilseeds Research Unit, Dr. PDKV., Akola (Maharashtra, India) to know the efficacy different chemical insecticides in the management of sunflower necrosis disease by controlling its vector Trips palmi. Statistically non significant difference was observed among the treatments towards germination. Seed treatment (ST) with Imidacloprid 600 FS @ 5 ml/kg seed and foliar spray with Imidacloprid 17.8 SL (T1) at 0.5 ml/L at 30, 45 and 60 days after sowing (DAS) recorded minimum i.e. 3.71 and 4.74 percent necrosis respectively, at one and two month after germination. ST with Imidacloprid 600 FS at 5 ml/kg seed and foliar spray with different insecticides were found at par with each other and significantly superior over untreated control towards necrosis disease of sunflower. ST with Imidacloprid 600 FS at 5 ml/kg seed and foliar spray with Trizophos 40 EC at 1 ml/L (T3) at 30, 45 and 60 DAS recorded higher seed yield 1165 kg/ha and found at par with other insecticide treatments. The control plot recorded lowest yield of 991 kg/ha and highest disease incidence 9.15 and 12.40 percent at one and two month after germination, respectively. ST with insecticide and foliar application of insecticides could be protected yield loss of sunflower due to necrosis virus disease.
