Abstract:
Plant hoppers are the major yield limiting factor faced by the farmers of Eastern
Vidarbha zone of Maharashtra who failed to achieve the control of hoppers with the
conventional insecticides which paves the way to introduce the new methods of management
practices for the plant hoppers in rice. Therefore alleyways in rice crop and its effect on
incidence of plant hoppers are studied at different location as field experimenti. Multi location
field trial on effect of alley ways on hoppers incidence in rice crop in randomized block design
with five replications of four treatments viz.,T1: Alleyways of 30 cm after every 10 rows or 2 m in
rice crop, T2: 2 Chemical sprays at 15 days interval (Flonicamid 50 % WG @ 3 g/10 Liter water at
60 DAT and Fipronil 5% SC @ 20 ml/10 Liter water at 75 DAT), T3:T1 + T2 and T4: Untreated
control at Agriculture Research Station, Sakoli, Dist. Bhandara and Zonal Agriculture Research
Station, Sindewahi, Dist. Chandrapur during kharif 2019 and kharif 2020. The results revealed
that treatment with alleyways of 30 cm after every 10 rows or 2 m in rice crop + 2 Chemical
sprays viz., Flonicamid 50 % WG @ 3 g/10liter water at 60 DAT and Fipronil 5% SC @ 20 ml/10
liter water at 75 DAT was found effective for management of hoppers and getting higher grain
yield of rice crop and higher monetary return.
