Host plant resistance has been a valuable tool in the management of planthoppers. The experiment was carried out to assess the level of total phenols, Ortho-dihydroxy phenols, Phenols, crude silica and total sugars in BPH (Brown Plant Hopper) affected rice leaves. Resistant varieties showed high amount of phenols, O.D. Phenols and crude silica as against low quantity of total sugars. These, biochemical basis of resistant method is also identifying the resistant variety against brown planthopper (Nilaparvata lugens) in rice.
Brown planthopper, Crude silica, Rice accessions, Total phenols, Total sugars
