- Abstract
Field experiments were conducted to evaluate IPM modules against Maruca vitrata F. and Helicoverpa armigera (Hubner) in black gram (Vigna mungo L. Hepper) during summer 2018 at the Chatha farm, SKUAST-Jammu. The IPM modules included: biorational module (m-I); chemical module (m-II); IPM module (m-III); farmer's practice (m-IV) and m-V as a control module. The results showed that the module-I was found to be superior against M. vitrata in the vegetative stage (6.00 larvae/ m2), flowering stage (17.67 larvae/ m2) and pod setting stage (12.00 larvae/ m2). The biorational module (m-I) was found to be superior to others in reducing the larval incidence of H. armigera at vegetative stage (1.33 larvae/ m2), flowering stage (8.00 larvae/ m2) and pod setting stage (5.67 larvae/ m2). On the basis of yield attributes, in case of M. vitrata, maximum yield was obtained from two pickings in module-I (20.00 q/ ha) followed by module-III (16.72 q/ ha), module-II (14.33 q/ ha) and module-IV (10.71 q/ ha); and maximum cost benefit ratio was observed in module-I (1:3.63). Maximum yield was observed in module-I (18.89 q/ ha) against H. armigera, with maximum cost benefit ratio of 1:3.49.
