Abstract:

Field experiments were conducted on small onion for white grub management using entomopathogenic fungi Metarhizium anisopliae (Metschnikoff) Sorokin and entomopathogenic nematode (Heterorhabditis indica) and synthetic insecticides (farmers’ practices) at Kurumbalur pudhur village, Perambalur district. Application of commercially available EPN (Heterorhabditis indica) @ 1 kg/acre against onion white grub Holotrichia serrata (Blanch) was found effective (95.28 %) followed by Metarhizium anisoplae @ 1 kg/ acre registered 83.02% reduction in grub population on 60th DAT. The highest bulb yield was recorded when basal application of H. indica (130.6 q ha-1), followed by M. anisopliae (101.8 q ha-1) and Farmer practices (84.6 q/ ha-1). Benefit cost ratio (BCR) was high with application of H. indica (3.15) followed by M. anisoplae (2.52) and farmers practices (1.90).


Keywords: Onion, White grub Holotrichia serrata, Heterorhabditis indica, Metarhizium anisopliae
