Evaluation of Bio-pesticides against Fall Armyworm, Spodoptera frugiperda (J. E. Smith) in Maize
An experiment was conducted under field condition at three locations viz., Entomology
Farm, B. A. College of Agriculture, AAU, Anand, Agricultural Research Station, Sansoli
and main maize research Station, Godhra during Kharif, 2019 to determine the efficacy of
different biopesticides against the fall armyworm, Spodoptera frugiperda in maize
(GAYMH-1) by using Randomized Block Design (RBD) with three replications. The
lowest larval population (1.81 larvae /10 plants and 2.03 larvae /10 plants), minimum plant
damage (15.34% and 17.70%) and cob damage (15.19 % and 15.19%) was observed in the
plot treated with Nomuraea rileyi 1% WP @ 40 g/10 lit water and it was at par with
Bacillus thuringiensis var.kurstaki 1 % WG @ 20 g/10 lit water, respectively. Of the tested
biopesticides, the highest grain and fodder yield was recorded from the plot treated with
N. rileyi 1% WP (2957 and 4069 kg/ha) and followed by B. thuringiensis (2932 and 4033
kg/ha).
