TAILIEUCHUNG - Comparative assessment of biocontrol agents (BGAs) and chemical insecticides on the incidence and management of major insect-pests in green gram (Vigna mungo L.) in West Bengal, India

A comparative assessment of spray efficacy of different bio-control agents such as Beauveria bassiana (Bb), Trichoderma viridae (Tv), Pseudomonas fluroscence (Pf), Verticillium lecanni (Vl), Metarhizium anisopliae (Ma) were tested in different combinations along with neem soil and chemical insecticides like imidachloprid and Acephate on major insect pest of green gram (Vigna mungo L). our results found that that, among the different treatments T-1 (Trichoderma viridae (Tv)+ Pseudomonas fluroscence (Pf)+ Beauveria basiana (Bb)+ Verticillium lecanni (Vl) sprayed @ 5g/L of water significantly reduced the population of both white fly and pod bug infestation showing significant efficacy of biocontrol agents. Minimum insect count/plant of pod bug was observed in T-1 ( insect/plant). T-1 showed minimum insects per plant ( insect/plant) in case of white flies. Treatment-1(T1) recorded Maximum number of branches (), maximum pods per plant (), maximum pod length ( cm), number of seeds per plant (), pod weight ( g) and test weight of the seeds (10 g) when compared to untreated control which recorded least numbers as compared to treated plots. T-1 was recorded with maximum activity of Phenols ( of leaf tissue), chlorophyll-a ( of leaf tissue), chlorophyll-b ( mg/g of leaf tissue), Total chlorophyll ( mg/g of leaf tissue) and total soluble sugars ( mg/g of leaf tissue). The least activities of all the biochemical factors were observed in untreated control. | Comparative assessment of biocontrol agents (BGAs) and chemical insecticides on the incidence and management of major insect-pests in green gram (Vigna mungo L.) in West Bengal, India
