Wheat (Triticum aestivum L.) is one of the major important cereal crops of India. Diseases like loose smut, karnal bunt, rusts (yellow and brown), powdery mildew and pests namely termites and aphid infestation are the major constraints to production in H.P. In this context 12 different IDM modules were tested and trial was laid out at Experimental farm of HAREC, Dhaulakuan with three replications in a Randomized Block Design during Rabi 2008–09, 2009–10 and 2010–11 seasons. Seed treatment with Vitavax @ 2.5 g/kg and chlorpyriphos @ 5ml/kg seed plus one foliar spray each of Tilt-25E @ 1 ml/l and chlorpyriphos @ 2ml/l was found most effective module as it resulted highest grain yield and least disease/pests infestation. The second most effective module was seed treatment with Raxil @ 1g/kg + endosulfan @ 5 ml/kg followed by one foliar spray of Tilt 25 EC @ 1 ml/l and endosulfan @ 2.5 ml/l. These two models were statistically at par with each other and significantly superior over others. Untreated check gave least grain yield with high disease/pests infestation. All the seed dressing fungicides were found compatible with chlorpyriphos, endosulfan and bio-control agent Trichoderma viride and there was no adverse effect on seed germination and disease control efficiency of the fungicides.
