Abstract:
The present investigation was studied in Zaid season 2022 at the student’s instructional farm, A.N.D. University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.). In the course of the research, the various treatments evaluated for the management of red pumpkin beetle (A. foevicollis), T_1- [Fipronil (Soil application) + Spinosad (Foliar Spray 30 g a.i. + 60 g a.i./ha] was observed most effective which caused the maximum mean reduction and gave highest yield 245.60 q/ha followed by T₂ - [Fipronil (Soil application)+ Spinosad (Foliar Spray) 30 g a.i.+30g a.i./ha] treated plots with 240.50 q/ha. The highest cost-benefit ratio is 22.76:1obtaine from T_5- [Fipronil (Soil application) + Neem Seed Kernel Extract (Foliar Spray 30g a.i.+10%/ha] and followed by T_3-[Fipronil (Soil application) + Parthenium leaf extract (Foliar Spray) 30g a.i. + 10%/ha] 16.68:1. The efficacy of remaining treatments in order of superiority were T_6- [Fipronil (Soil application) + Neem Seed Kernel Extract (Foliar Spray 30g a.i.+10%/ha], T_7- [Fipronil (Soil application) + Lantana Leaf Extract (Foliar Spray 30g a.i. + 5%/ha] T₄–[Fipronil (Soil application)+ Parthenium leaf extract (Foliar Spray) 30g a.i.+5%/ha].The least effective treatment was recorded T₈-[Fipronil (Soil application) +Lantana Leaf Extract (Foliar Spray) 30g a.i. + 10%/ha] and T_{9 –}[500 litters water spray], respectively.
