Abstract
A biointenisve pest management (BIPM) module was synthesized and
assessed for its effectiveness against diamond back moth (DBM) (Plutella
xylostella L.) and green peach aphids (Myzus persicae Sulzer) that
were infesting cabbage in Varanasi, Uttar Pradesh during the years 2023 and
2024. The BIPM module comprising sowing of Indian bold seeded mustard (Brassica
juncea (L.) Czern.) as a trap crop (25:2); installation of sex pheromone
traps for DBM @ 12/acre from 30 days after translating (DAT), periodical
release of Trichogramma chilonis @ 100000/ha; sprayings of Bacillus
thuringiensis NBAIR BtG-4 (2x108 cfu/g) 1% WP @ 2 g/lit with
each application occurring at 10-day intervals. Additionally, one spraying of Azadirachtin
1500 PPM @ 2 ml/lit and subsequent spraying of Lecanicillium lecanii
NBAIR VL-8 (1x108 cfu/g) @ 5 g/lit of water at 10 days intervals during
the onset of DBM had shown lowest DBM population (5.57/ cabbage plant) with
highest percent reduction over control (60.16) than the Package of practices
(32.40 PROC) and untreated control. Similarly, the incidence of polyphagous M.
persicae was also found lowest in BIPM modules and mean population 3.31 per
leaf followed by PoP (5.48 per leaf) and untreated control plots (7.86 per
leaf) and thereby the BIPM practices registered highest PROC (57.89) followed
by PoP (30.28 PROC).
