Fall armyworm Spodoptera frugiperda (J.E.
Smith) is an economically important insect pest of maize
and spreads very widely in different agroecological zones.
A field experiment was conducted to investigate the fall
armyworm incidence on maize hybrid DHM 121 under
different dates of sowing during kharif 2021 and rabi
2021-22. The results revealed that the peak per cent
plant infestation by fall armyworm was observed in 42,
63 and 91 days old maize crop at 49th, 52nd, and 4th SMW
(100.0%) in crop sown during 23rd October, 2021.
Similarly, the peak larval incidence was observed in 84
day old crop at 5th SMW (0.65) in crop sown on 10th
November, 2021 whereas the maximum oviposition was
observed in 77 day old crop at 44th SMW (0.18) in crop
sown on 17th August, 2021.The information obtained from
the present study would help formulate fall armyworm
forecasting models and potential management strategies
in maize.
