ABSTRACT
Three separate field experiments were conducted in 2001, 2002 and 2003 to determine the efficacy of combining sowing date, seed treatment with metalaxyl and use of host plant resistance for the control of pearl millet downy mildew. Early sowing gave lower disease incidence and higher grain yield than late sowing.The disease was controlled when metalaxl treated seeds were sown early. The highest disease incidence and the lowest grain yields were obtained when untreate seeds were sown late.Use of resistant pearl millet cultivar along with seed treatment using metalaxyl at the dose of 2 g a.i./kg seeds greatly reduced disease incidence and increased grain yield in comparison with the seed treatment of susceptible cultivar
