Efficacy of insecticidal seed treatment on seed viability and seed damage during storage under ambient condition. Crop: chickpea (Cicer arietinum L.)

Abstract

The experiment was conducted at Seed Technology Research Unit, Main Pearl Millet Research Station, J.A.U., Jamnagar during 2015 on chickpea with an objective to ascertain new insecticidal chemical agaist Callosobruchus chinensis, a major pests of stored chickpea seed. The observation on moisture content, germination and insect infestation were recorded at interval of three months of storage period. Moisture content in chick pea was found non-significant up to 9 months of storage period. The effect of different treatments on germination was found non-significant at up to 6 months of storage period. Among different insecticides, At 9 months, majority of the chick pea treated seeds were from damage except Rynaxypyr @ 2 ppm (1.00%) and control (18.67%). At 12 months, lowest incidence was recorded in Emamectin benzoate @ 2 ppm (1.00%). While in control it was 29.27 % seed damage.
