Management of Major Insect Pests of Pearl Millet under Organic Cultivation
A field experiment was conducted at Pearl millet Research Station, Junagadh Agricultural University, Jamnagar during Kharif 2016 to 2018 to find out the effective and economical control measures against the major insect pests in pearl millet for organic cultivation. The bio-efficacy of different bio-pesticides viz., HaNPV (6×109POB/ml) @ 250 LE/ha, Bacillus thuringinensis var kurstaki @ 5% WP @ 0.01 %, Beauveria bassiana 1.15 WP (2×106 cfu/g) @ 5g/lit, Lecanicillium lecanii 1.15 WP (2×106cfu/g) 5g/lit and NSKE 5 per cent were evaluated agaisnt the major insect pests in pearl millet crop. The treatment of B. bassiana 1.15 WP (2×106 cfu/g) @ 5g/l recorded the least incidence of shoot fly (7.2%) and stem borer (5.36%) at earhead stage of the crop. Whereas, in case of ear head worm Helicoverpa armigera, treatment of HaNPV (6×109POB/ml) @ 250 LE/ha recorded the lowest larval population (5.78 larvae /20 ear heads) and it was at par with B. thuringiensis @ 1.0 kg/ha (8.36 larvae /20 ear heads) and B. bassiana @ 5g/l (9.87 larvae /20 ear heads). The treatment of B. bassiana @ 5g/l also recorded the highest grain yield (1727 kg/ha) followed by HaNPV @ 250 LE/ha (1490 kg/ha).
