Observations are taken at every 5 to 10 km distance, 10 spots per ha randomly and 10 plants per spot.
-
Install pheromone traps 10 per ha to monitor moth population of Helicoverpa and Spodoptera litura.

-
Install 15 bird perches per hectare for predatory birds.
-
Release 1-2 larva per plant of Chrysoperla carnea at early stage of crop.

-
Use NPV @ 250 LE/ha against Helicoverpa and Spodoptera .
-
Use B.t. (K) 1 kg/ha against Spodoptera.
-
Release 1-2 larva per plant of Chrysoperla carnea at early stage of crop
-
Conserve bio-control agents like Cotesia spp., spiders, anthocorids, Chrysopa, Lady bird beetles, mandits and reduvid bugs.
