An IPM Module was developed at Agriculture Research station, Sriganganagar for this zone. The components of module are

Deep summer ploughing,
Use crop rotation
Use of tolerant varieties,
Planting of bio-agents conservation crop (maize + cowpea + bajra) two rows around the field at the time of first irrigation,
Remove weeds in and around the field
Excess use of nitrogenous fertilizers should be avoided
Use of chemicals should strictly on the basis of ETL
Use of pheromone traps
Hand picking & killing of larvae of Heliothis and Spodoptera
First two spray of neem based insecticide should be done
One spray of each Trizophos and Indoxacarb at boll formation stage
Use of synthetic parathyroid for the control of whitefly and American bollworm should be avoided

Insecticide resistance management is a component of integrated pest management. By following IRM activities, building of resistance in the insects against insecticides can be checked and insecticides can be made effective against insects for longer period. Following recommendations (window system) were included in package and practices.

S.N.	Days after sowing/Insects	Strategy	Rationale
1.	Up to 60 days for sucking pests	Sowing sucking pests resistance verities Use the Thiomethoxam /Imidacloprid for for seed treatment. Spray the Neem insecticide or Endosulfan	To avoid early sprays. To avoid disturbing beneficial insects (predator and parasite).
2.	60-90 days bollworm management	On the basis of ETL, spray of Endosulfan. Use Ha NPV/ NSKE at ETL basis.	Safe for beneficial and low initial resistance. Early broods are young & uniform and can be controlled with biorationals.
3.	90-110 days bollworm management	Use the Organophosphates/ Carbamates on ETL basis. Use any of the following : (Quinolphos or Chlorpyriphos or Profenophos or Thiodicarb or Spinosad) spray once if ETL is reached	Natural enemies population declines after 90 DAS. Resistance to Organophosphates/ Cabamates is very low at this stage.
4.	110-140 days bollworm management	Pyrethroids can be used for spotted & pink bollworms. New Chemical: Indoxacarb and Spinosad once at ETL basis. Whitefly Management: Use Trizophos or Ethion or Thiomethoxam.	Pyrethroid work best against bollworms. Indoxacarb works best on Pyrethroids resistant larvae. Never mix Indoxacarb with Organophoaphates.
