Abstract:
The KVK, Bhadradri Kothagudem conducted front line demonstration during Kharif season of 2019-20, 2020-21 and 2021-22 in KVK operational area of adopted villages on “Management of Stem Weevil in Cotton”. Demonstrations were conducted in ten different farmers fields to assess the damage potential and its management strategies. Two treatments viz., technology demonstration i.e application of neem cake to the soil mixed with farmyard manure (FYM) during the basal fertilization (10 tons FYM + 250 Kg of Neem cake/ha). Prophylactic spray of Chlorpyriphos 2.5 ml/l of water. In case of severity, application of chlorantraniliprole 18.5 SC at 0.3 ml/l and clothianidin 50 WDG at 0.2 g/l of water and check (farmers practice) i.e., spraying of Chlorpyriphos 2.5ml after observation of insect incidence. Significant higher income was recorded from the technology demonstrated plot over the three years compared to control plot. On an average, the benefit cost ratio was high in treatment i.e., 1.98, 1.78 and 1.98 compared to control plot i.e., 1.53, 1.43 and 1.62 during Kharif 2019-20, 2020-21 and 2021-22 respectively.
