Effect of new insecticide molecule on insect management and seed quality attributes in maize (Zea mays L.)

Abstract

A field experiment was conducted at National Seed Project, UAS, GKVK, Bengaluru during the year 2018-19, to know the effect of new insecticide molecule called chlorantraniliprole on quality attributes in maize inbred line CAL 1443. The experiment was laid out in RCBD, replicated three times with ten treatment combinations, Chlorantraniliprole 0.1, 0.2, 0.3 ml / kg (ST) Chlorantraniliprole 0.1 ml 0.2, 0.3 ml / kg (ST)and spray with chlorpyrifos 2 ml at 45 DAS, Chlorantraniliprole 0.1, 0.2, 0.3 ml / kg (ST)and spray with quinolphos 2 ml at 45 DAS, Control. The results revealed that Chlorantraniliprole 0.3 ml / kg (ST)and spray with quinolphos 2 ml at 45 DAS recorded least per cent leaves damage and highest Seed quality attributesviz, least percent leaves damage at 60 DAS (7.37 %),Seed germination (93.00 %), mean seedling length (33.65 cm), mean seedling dry weight (56.10 mg), seedling vigour index I (3103) and seedling vigour index II (5216) over control (90.33 %,23.40 %, 31.91 cm, 55.41 mg, 2914, 5005 respectively).
