Abstract
The economic injury level (EIL) of pod borer complex of pigeon pea (T-21) was found to be 4.2% flower and pod infestation. The infestation reaches this level between the last week of November and first week of December i.e. after one week of the pigeon pea crop to the pest infestation in both the years. Control measures to be given sometime during the early part of the last week of November in order to check the increasing infestation from reaching the economic injury level. Maximum (38.06 q/ha) and minimum yield (19.45 q/ha) were recorded when the lowest (2.0%) and highest (40.6%) flower and pod infestation occurred during full protection (FP) and no protection (NP) treatments, respectively. A significantly high negative correlation (r = −0.96, P = 0.01) existed between damage % and healthy yield. The maximum yield loss over FP was 18.61 q/ha.
