Abstract The results revealed that the minimum incidence of whitefly was recorded in treatment when tubers were treated with Thimethoxam with mean incidence of 2.33–6.0/5 plants from third week of October to first week of December during crop growth followed by Imidacloprid (2.33–5.0/5 plant) and Fipronil (2.33–5.67/5 plant). The maximum mean disease incidence (21.93%) was recorded in the untreated tubers followed by Propargate (21.10%) and Acetamiprid (21.30%) in sprayed treatments, which is at par. However, mean total tuber yield did not differed significantly among treatments. Highest mean tuber yield (13.27 t/ha) was recorded when seed tubers were treated with Imidacloprid followed by Thimethoxam (13.24 t/ha) and Fipronil (13.07 t/ha) followed by single spray of respective insecticide in protected treatments. Therefore, present study revealed that Imidacloprid or Thimethoxam could be effectively used as a seed treatment followed by single spray of respective insecticide as per the incidence of whitefly on early potato crop.
