In the management of PBND in groundnut neem seed extract (10%), we recorded significantly lower PBND incidence, AUDPC, apparent infection rate (20.41, 19.5% PBND; 956, 756 AUDPC; 0.0026, 0.002 apparent infection rate) followed by neem cake extract 10% spray (2747, 23.36% PBND; 1275, 1316 AUDPC; 0.0034, 0.0025 apparent rate of infection in 2000–2001 and 2001–2002, respectively). Weekly spray of monocrotophos reduced the PBND (26.77%) and recorded significantly higher pod yields (2547, 2465 kg/ha) and lower AUDPC (861, 1373), and apparent infection rate (0.0021, 0.0019 in 2000–2001 and 2001–2002, respectively) compared to other treatments.
