Abstract

The economic threshold level is the key decision-making tool in any IPM programme. A field experiment was conducted to determine the economic threshold level for gram pod borer Helicoverpa armigera (Hubner) in chickpea at Agricultural Research Station, Anand Agricultural University, Derol, Dist. Panchmahals, Gujarat, India during the rabi in 2016-17, 2017-18 and 2018-19. The economic injury level for H. armigera was found to be 0.67 larva/ plant, whereas the economic threshold level was 0.60 larva/ plant.
