  IMP (Integrated Pest Management in Intensive Forage Production)  
 
 
The sustainability of the fodder production systems largely depend upon overcoming biotic stress factors. At IGFRI several promising fodder crop production systems with recommended agronomical package of practices are available that confer higher forages and are incredibly valuable for intensive dairy production units. One of such system is NB Hybrid + Cowpea - NB Hybrid + Berseem, for which standard crop production technology is available. With the changing pest status and awareness on environmental degradation, it becomes necessary to modify the present plant protection practices with the more environmental friendly safer molecules and bio-pesticide based plant protection practices. Various IPM modules were studied for the management of biological stress factors in this system. The results revealed that second sowing date (1st week of July) + seed treatment of thiomethoxam + pencycurone (@ 0.5gm/kg seed) along with foliar spray of imidacloprid + tebuconazole (@ 0.025% conc.) was found to be the most effective IPM module as it resulted in significant reduction of biotic pressure on the crop ( 11.80% reduction in the root rot intensity caused by Rhizactonia bataticola, 75.00% reduction in leaf spot, Cercospora cruenteae and 61.50% reduction in flea beetle, Pagria signata incidence, 52.80% reduction in semilooper, Plusia nigrisigna damage, 32.4% in grasshopper, Hieroglyphus nigrorepletus damage and 51.19% reduction in plant parasitic nematodes, Meloidogyne incognita in cowpea and 75.00% reduction in leaf blast, Pyriculareae graceae and 33.8% in grasshopper, Hieroglyphus nigrorepletus damage in NB hybrid was recorded). This treatment yielded maximum GFY (65.43t/ha, an increase of 18.04% over control), for NB Hybrid + cowpea component of this system. In Rabi most effective IPM module was first sowing date in combination with seed treatment of thiomethoxam + pencycurone (@ 0.5gm/kg seed) along with foliar spray of imidacloprid + tebuconazole (@ 0.025% conc.) as this combination significantly reduced biotic pressure on the crop ( 58.06% reduction in the root rot intensity caused by Rhizoctonia solani and Fusarium semitectum in berseem, 78.65% reduction in aphid population (Lipaphis erysimi Kalt) and 52.55% reduction in plant parasitic nematodes (Tylenchorhynchus vulgaris) and yielded maximum GFY (89.52t/ha, an increase of 17.05% over control).
