| 520 | _aWheat has been ranked as the most important crop for food security in Bangladesh. Disease is one of the major constraints in limiting wheat productivity. Following the development of rust resistant varieties, spot blotch is now the most destructive disease of wheat in the rice-based cropping system of Bangladesh. At present, almost all released varieties show varying degrees of spot blotch susceptibility, but no germplasm has been found to be highly resistant. Emphasis was given on screening for disease resistance in a routine manner. Since, host resistance is not satisfactory, chemical control becomes an economically viable supplement to crop loss. The best chemical way to protect yield loss from spot blotch is to foliar spray a fungicide combined with seed treatment. From a number of years of experiments the average yield loss due to spot blotch was estimated at 15%. After conducting a series of experiments with varying rates of fungicides and from an economic and environmental viewpoint, a single spray of fungicide Tilt 250EC (125 a.i./ha ) combined with seed treatment (Vitavax-200TM @ 3g/kg of seed) at the dose 1ml/1L of water/20m2 , at 35-50 days after sowing (booting to heading) was found profitable for successful wheat production. The cost benefit ratio was found 1:5. | ||
