Wheat disease surveillance and monitoring in Bangladesh

Disease surveillance and monitoring has been regularly organized by Wheat Research Centre (WRC), in major wheat growing areas of Bangladesh since 2010-11 to track the current status of common diseases, first outbreak of new disease(s), the pathogen hotspot and identify new virulent races. Besides the paper based traditional survey, scientists of WRC are now using different tools like Smartphone/Tablet with supporting applications. Several trainings were arranged under DGGW project on rust tool box in Bangladesh. Among all smartphone applications, RustSurvey is the easiest and handy application which integrates with the SAARC Surveillance Toolbox.
A disease surveillance program on wheat blast was organized in Mid February 2017 followed by hands on training in collaboration with CIMMYT and CU, USA. Out of 103 sites surveyed, 33 sites were found infected with wheat blast. Overall disease incidence was comparatively lower than the previous season with low disease severity (5-10%). Surveillance program on rust diseases was also conducted in early March 2016. Among 102 rust survey sites stem rust and yellow rust was not found, but leaf rust occurred with varying levels of severity depending on field locations, sowing times and cultivars grown. About 52% of the 102 fields investigated had leaf rust, and almost 73% of the infected fields showed low (<20%), 21% moderate (20-40%) and only 6% showed high (more than 40%) disease severity. Timely (15-30 November) planted crops largely escaped or had less disease compared to those planted late in the season. The predominant cultivar Prodip as well as BARI Gom 25 and 26 showed zero to high disease levels with MSS type reactions. BARI Gom 21, 28, 29 and 30 were free from leaf rust infection. Furthermore, Spot blotch was found in most of the region with low to high level field incidence depending on crop growth stage.
