Effect of Newer Insecticides as Fabric Treatment on Maize Seed Viability duringStorage under Ambient Conditions

摘要

A storage experiment was conducted to study the effect of packaging material with insecticides viz., Flubendiamide 480 SC @100ppma.i., Emamectin benzoate 5 SG @100 ppm a.i., Spinosad 45 SC @100ppm a.i., Deltamethrin 2.8 EC@100 ppm a.i., Untreated control and three different storage bags of Gunny bag, Porous High Density Polyethylene (HDPE) bag and Cloth bag for controlling Sitophylus zeamais M., S. oryzae (Linn.) insect pests of maize under ambient conditions from 2010 to 2013. The results revealed that spinosad 45SC @100 ppm a.i. was most effective by recording highest germination (85.48 per cent) and least seed damage (0.6 per cent) at nine months after treatment imposition, closely followed by emamectin benzoate 5 SG @100 ppm a.i. (84.74 and 1.24per cent respectively). However, with respect to packaging material, the highest germination (82.80 per cent) and least seed damage (2.51 per cent) was observed in porous HDPE bags. Among the interactions, the highest germination (87.00 per cent) and least seed damage (0.44 per cent) was observed in porous HDPE bags treated with spinosad 45 SC after nine months of storage. The cost benefit ratio was highest (1:14.98) in HDPE bags treated with spinosad 45 SC.
