Abstract

Field experiments were conducted during three kharif seasons from 2009 to 2011 at Sudhar village, Ludhiana and Rice Research Area of Department of Plant Breeding and Genetics, Punjab Agricultural University, Ludhiana. Four doses of Ferterra 0.4% GR (chlorantraniliprole) a new chemistry @ 20, 30, 40 and 50 g a.i. ha^-1 and standard check Cartap hydrochloride 4 G @ 1000 g a.i. ha^-1 was tested against stem borers and leaffolder infesting basmati rice. Over the years, dead heart in all the Ferterra doses and standard check (1.01-1.80 %) were at par 70 DAT, whereas, at 80 DAT doses @ 40, 50 and standard check were at par (1.04-1.13 %) but significantly better than lower doses and untreated control.? Similarly, over the years, Ferterra doses @ 40 and 50 g a.i. ha^-1 was significantly better than control in reducing white ear incidence, whereas, at 30 g a.i. ha^-1 and standard check intermediately reduced the white ears incidence. Leaffolder infestation at all the Ferterra doses were at par with standard check 70 DAT (2.69-3.87 %), whereas, 80 DAT, Ferterra doses @ 30, 40, 50 and standard check were at par (2.95-3.49 %) but significantly better than lower dose and untreated control. Over the years the cost : benefit ratio was maximum (1 : 23.67) in the Ferterra @ 40 g a.i. ha^-1 dose followed by 50 g a.i. ha^-1 dose. ?
