​Management of White Grub, H. consanguinea in Groundnut using Entomopathogens

Abstract

The white grubs infests diverse crops of food and horticultural importance such as groundnut, sugarcane, kharif pulses, vegetables areca nut, ginger, potato, etc. and it inflict losses as high as 100 per cent, depending upon the severity of infestation have been uncommon. In present study, attemts have been made to explore the potentiality of entomopathogens for the management of the white grub Holotrichia consanguinea a serious pest in groundnut crop in Rajasthan during kharif seasons, 2018 and 2019. Results revealed that furrow application of Beauveria bassiana, Metarhizium anisopliae powder formulation @ 5 kg (1×1012 CFU/gm) and H. indica galleria @ 5000 galleria per hectare at the time of sowing were significantly superior in reducing the per cent plant mortality (28.00%, 29.33%, 31.77%, respectively) and increase yield over untreated control (12.82, 11.53, 10.78 q/ ha respectively).

White Grub (<i>Leucopholis coneophora</i> Burmeister) Management in Mid-Hill Region of Meghalaya

“…After China, India is the world's second-largest producer and consumer of groundnut. In India, groundnuts are grown to produce 6.69 mt across 4.81 million ha (Anonymous, 2019;Yadav and Baloda, 2022). In the northeastern region (NER) of India, it is a non-traditional crop, but the average production suggests that the region has a tremendous potential.…”
