    This document presents a proposal for a seminar on eco-friendly management of brinjal shoot and fruit borer (Leucinodes orbonalis) under field conditions. The study will evaluate 7 treatments, including neem seed kernel extract, wood ash, pheromone traps, tobacco leaf extract, an insecticide, and an untreated control, applied over 3 spray intervals. Data on shoot and fruit infestation rates and yield will be collected and analyzed to identify effective and environmentally-safe management strategies for this key pest of brinjal crops.

    Eco-friendly Management of Brinjal fruit and shoot Borer


    (Leucinodes orbonalis) under the field conditions

    INTRODUCTION
    • Scientific Name : Solanum melongena L.
    • Family : Solanaceae
    • It is often called as “Baingan" or “Brinjal“ or “Egg
    plant" or “Aubergine".
    • In Nepal, the production of brinjal during 2016/17 was
    128029 Mt from 8680 ha with productivity of 14.7
    Mt/ha(MOAD,2016/17)
    • According to FAO in 2012, China ranks first in the
    production of brinjal (58% of world output).
    • It is a good source of vitamins, antioxidants, proteins
    and fibers (Obho, et.al,2005).
    • The longer fruiting and harvesting period with higher
    yield attracts farmers on brinjal cultivation
    Shoot & Fruit Borer of Brinjal
    • key insect pest of egg plant in all eggplant
    growing regions of Nepal (Mainali,et.al,2015).
    • a monophagous pest feeds only on Brinjal.
    • A single caterpillar may damage 4-6 fruits
    which shows circular exit holes.
    • reduces the crop yield upto 60-70% (Singh
    &Nath,2010).
    • Singh et al. (2000) reported that the borer
    infestation was 78.66% on top shoots in
    vegetative phase and then shifted to flowers and
    fruits with infestation reaching 67 % in fruiting
    phase.
    • infested fruits have remarkable reduction in vit. C
    content (Ali et.al.,1980).
    • Farmers apply insecticides 10-12 times in winter
    and 25-30 times in the summer and rainy season
    crop (Ghimire,2001).
    • Absence of economical, eco-friendly and socially
    accepted solutions is a key constraint (IPM CRSP,
    2001)
    OBJECTIVE:

    • To study environmentally safe, economically


    feasible, locally available and actionably
    effective Brinjal shoot and fruit borer
    management strategy.

    • Data Record interval: one day before spray,
    3rd, 7th and 11th days after each spray.
    Data To be taken

    Shoot infestation percent: (Number of infested


    shoot/Total number of shoots)*100
    Fruit infestation percent (by number):
    (Number of infested fruit/Total number of
    fruits)*100
    Fruit infestation percent (by weight): Fruit
    infestation percent (by weight) = (Infested fruit
    weight/Total fruit weight)*100
    Increase in yield over control (%): [T-C]/C*100
    Analysis

    • Recorded data tabulated first


    • GENSTAT for analysis
    • DMRT for significant differences among
    treatments
