ABSTRACT
A field experiment was conducted during Kharif, 2015 at the Entomological Research Farm of College of Agriculture, Central Agricultural University, Imphal (Manipur) to assess theefficacy of eco-friendly insecticides against Rice leaf folder (Cnaphalocrocismedinalis Guenee). Among the various eco-friendly insecticides field evaluated against the Lepidoterous pests(Acephate 50% +Imidacloprid 1.8) 51.8 SP@750 g/ha performed significantly better than rest of the insecticidal treatments with a record of minimum leaf damage incidence (1.02% LD) as against 1.42% in untreated control plot. The maximum mean extent of leaf damage (1.34% LD) was recorded in Lastraw @ 1000 ml ha-1. The lower per cent mean leaf damage was also recorded in the plots treated withEMFPE @ 2500 ml/ha (1.05 % LD) and Achook @ 1500 ml/ha (1.09 % LD) which did not differ significantly from one another.
Key words: (Cnaphalocrocismedinalis Guenee, Lepidoterous pests, Acephate, Imidacloprid.
