Field experiments conducted at Tamil Nadu Rice Research Institute, Aduthurai to develop a better pest management programme to brown planthopper (BPH). green leaf) hopper (GLH) and stemberer (SB) revealed that the variety ADT 31 recorded lower population of BPH and very low SB incidence during kuruval season. During thaladi, BPH population and SB damage were lesser in white ponni, CO 43 and RP 1-14. PY 3 and CO 43 registered higher yield during kuruvi and thaladi respectively wtth lesser incidence of above two pests: Application of carbsfuran 3 G@ 125 kg a. i/ha on 30 days after trausplanting (DAT) during kuruvai and on 5 DAT during thaladi reduced both GLH and BPH population resulting in higher grain yields.
