Abstract:

A study was conducted to evaluate the effectiveness of some newer insecticidal molecules viz., Emamectin benzoate (Proclaim 5 SG) @ 2 ppm, Spinosad (Tracer 45 SC) @ 2 ppm, Indoxacarb (Avaunt 14.5 SC) @ 2 ppm, Rynaxypyr (Coragen 20 SC) @ 2ppm, Chlorfenapyr (Intrepid 10 EC) @ 2 ppm, Profenofos (Curacron 50 EC) @ 2 ppm, Novaluron (Rimon 10 EC) @ 5 ppm, Deltamethrin 2. 8 EC @ 1 ppm along with untreated control against rice weevil and to assess the storability of treated seed. All the nine treatments were replicated thrice and statistically analyzed by using completely randomized design. The data on germination percentage, seedling vigour index, moisture content (per cent), seed damage (per cent) and adult emergence at every three months interval upto nine months of storage were recorded. The results revealed that Spinosad (Tracer 45 SC) @ 2 ppm kg-1 seed had recorded highest germination percentage (93.67), seedling vigour index (3113), less moisture per cent (11.33), lowest infestation (0.33 per cent) and adult emergence (1.00) at the end of nine months of storage.
