abstract
The field experiments were conducted during Kharif 2014 and 2015 at Agricultural Research Farm, Banaras Hindu University, Varanasi, U.P. to determine the effectiveness of some insecticides and biopesticides against Mung bean yellow mosaic virus (MYMV) in Mung bean. The results revealed that lowest incidence of MYMV disease was recorded from T₂-Imidacloprid 50 g a.i./ha followed by T₅-Acetamiprid 20 g a.i./ha, T₄-Fipronil 100 g a.i./ha and maximum from T₆-Metarhizium anisopliae (1×10⁸ Spores/g) 5 g/L followed by T₇-Beauveria bassiana (2×10⁸ Spores/mL) 2.5 mL/L. The maximum percent protection of MYMV over control was recorded from T₂-Imidacloprid 50 g a.i./ha (83.55%) followed by T₅-Acetamiprid 20 g a.i./ha (75.04%), T₄-Fipronil 100 g a.i./ha (65.09%) and minimum in T₆-Metarhizium anisopliae (1×10⁸ Spores/g) 5 g/L (9.79%) followed by T₇-Beauveria bassiana (2×10⁸ Spores/mL) 2.5 mL/L (14.50%).
