fertility status, besides well-irrigated sources. Further, conducted baseline survey before
grounding the demonstrations to identify the issues related to maize production and also studied
the socio-economic status of adopted farmers. The front-line demonstrations on Integrated Pest
Management of fall armyworm in maize comprised cultural, mechanical, and chemical
methods. At each location, the demonstration was laid out in an area of 0.4 ha and adjacent 0.4
ha was considered as control (farmers’ practice) for comparison studies. Apart from
showcasing the viability of pest management components, farmers were also sensitized on the
relevance of these technologies by organizing awareness programs, focused group discussions,
conducting method demonstrations and training programs.
Results
The results of front-line demonstrations on integrated pest management of fall armyworm in
maize (Table 1 and 2) indicated that the pest incidence and damage due to FAW range was 8.4-
14.0 percent in IPM followed plots during kharif 2019-20, whereas the average pest incidence
was 11.44 percent. In the Non-IPM plots, it was found that the pest incidence ranged from 28.6
to 36.4 percent and the average pest incidence was 32.6 percent. During rabi 2020-21, the FAW
damage was very less compared to kharif season, and the damage range was 3.3 – 10.0 percent
in IPM followed plots, whereas the average pest incidence was 6.98 percent. The Non-IPM
plots showed that the pest incidence ranged from 13.3 to 23.1 percent, with an average pest
incidence of 16.6 percent.
