Abstract: The experiment was conducted at experimental field agriculture jaffarabad during the season 2018-19,for sucking insects pests control.Maximum reduction in thrips population (30.3%) was observed in plot sprayed with neem seed extract followed by plot sprayed with neem oil (26.47%), tobacco extract (24.00%) and akk plant extract (19.83). Neem seed extract showed higher efficacy (81.01%) against thrips population on mustard crop followed by neem oil (66.13%), tobacco extract (58.20%) and akk plant extract (53.12%). Maximum reduction in whitefly population (13.00%) was observed in plot sprayed with neem seed extract followed by plot sprayed with neem oil (10.33%), tobacco extract (9.50%) and akk plant extract (7.33%). Neem seed extract showed higher efficacy (88.67%) against whitefly population on mustard crop followed by neem oil (80.51%), tobacco extract (79.16%) and akk plant extract (64.69%). Maximum reduction in aphid population (14.33%) was observed in plot sprayed with neem seed extract followed by plot sprayed with neem oil (11.10%), tobacco extract (10.23%) and akk plant extract (9.60%). Neem seed extract showed higher efficacy (87.75%) against aphid population on mustard crop followed by neem oil (76.02%), tobacco extract (71.38%) and akk plant extract (68.57%). Maximum reduction in painted bug population (8.67%) was observed in plot sprayed with neem seed extract followed by plot sprayed with neem oil (8.00%), tobacco extract (7.66%) and akk plant extract (6.76%). Neem seed extract showed higher efficacy (83.93%) against painted bug population on mustard crop followed by neem oil (77.44%), tobacco extract (71.85%) and akk plant extract (67.60%). Maximum crop yield (22 kg/plot) were recorded when the neem seed extract was sprayed on mustard crop; followed by average crop yield of 20 and 18/plot when the mustard crop were sprayed with neem oil and tobacco extract.respectively.
