dc.description.abstractThe investigation entitled “Bio-efficacy of confidor insecticide and evaluation of rice breeding lines against brown planthopper Nilaparvata lugens (Stal.)” was conducted in the field and glass house, Department of Entomology, IGAU, Raipur, during the kharif and rabi 2001-2002. The application of confidor 200 SL @150 ml/ha was the most effective against brown planthopper, green leaf hopper and gall midge. But there was no effect of the insecticides on different biological parameters on paddy crop viz. plant height, panicle length, total tillers number of grains per panicle and yield. Aum neem @500ml/ha was the safest insecticides as far as natural enemies are concerned particularly for dragon fly. In Aromatic rice, out of 250 accessions tested 6 cultivars namely Kabri Mohar (k:2497), Bishnu Bhog ( B: 1094II) , Kala Jira (K: 1456), Samunder Fen (S : 6721), Samund Chini(S : 980) and Manjali Dubraj (M : 915) were found resistant against brown planthopper whereas 10 accessions were moderately resistant to BPH attack. In State Uniform Variety Trial (SUVT), out of 27 varieties tested, 4 varieties namely R 975 – 897 – 1- 1, R 1217 – 539 – 1 – 262 – 1, IR – 36 and R 1182-167-2-157-1, were found resistant against brown planthopper and 15 entries moderately resistant to BPH.en_US
