Abstract:
A field experiment was conducted in Randomized Block Design to study the seasonal incidence of safflower aphid in relation to different five dates of sowing during Rabi season of 2020-21. The safflower variety Manjeera was sown to record the observations. The population of aphids /5 cm apical shoot length per plant ranged from 2.00 to 89.07,1.20 to 97.25, 1.75 to 110.30, 2.15 to 114.02 and 1.10 to 132.40 on 19^th Oct., 29^th Oct., 9^th Nov., 19^th Nov., and 29^th Nov.2020 sown safflower respectively. The early sown safflower crop evidently escaped the incidence of aphids during early vulnerable stages of the crop growth and further the mean aphid activity over a period of 18 weeks after sowing was significantly low as compared to other four sowing dates.
