Abstract
The maize stem borer (Chilo partellus)
is a serious pest of maize crops in Bihar's alluvial plains, causing severe
output losses. Effective management measures are required to limit the damage
and assure long-term maize production. This study assesses integrated pest
management (IPM) techniques, such as cultural, biological, and chemical control
measures, for C. partellus management in the region. Field trials were
carried out to determine the efficacy of various control methods. Cultural
measures include timely planting, intercropping with non-host plants (e.g.,
cowpea), and thorough ploughing have been shown to minimise borer infestation.
The introduction of Trichogramma chilonis (an egg parasitoid) was the
most effective biological control agent in terms of larval population
suppression. Furthermore, the use of neem-based bio-pesticides (Azadirachtin
0.15%) was successful in minimising larval damage. Chemical control measures,
such as the use of chlorantraniliprole 18.5 SC and emamect in benzoate 5 SG,
effectively eliminated pests while being environmentally safe. However, relying
only on chemical pesticides raises worries about resistance development and
environmental dangers. As a result, an integrated approach combining cultural
practices, biological management, and the prudent use of chemical pesticides
was shown to be the most successful technique for managing C. partellus.
The study suggests that using an IPM technique adapted to Bihar's alluvial
plains can dramatically reduce maize stem borer damage, increase crop
production, and promote sustainable agriculture. Additional study is necessary
to improve these tactics and provide more environmentally friendly pest control
options.
