| Title : | SURVEY OF KARNAL BUNT IN MEERUT DIVISION FOR MITIGATING PHYTOSANITARY RISK IN WHEAT EXPORT |
| Abstract : | Karnal bunt of wheat caused by Tilletia indica Mitra (Nevossia indica Mundkur), was first reported in Karnal, India, in 1931 hence named as ‘Karnal bunt’. The disease mainly occurs in wheat growing regions with low winter temperatures and high humidity and affects mainly common wheat, durum wheat, triticale and other related species. This pathogen poses a serious quarantine problem and thus restricts the international trade of wheat. Therefore, quarantine restriction is applied by approximately 70 countries on wheat trade where Karnal bunt is known to occur. To access the status of Karnal bunt in major wheat growing regions of Meerut Division Western Uttar Pradesh, apost-harvest survey was conducted during the year 2021-22 and 2022-23. In the survey six Districtsof Meerut Division viz., Meerut, Bulandshahar, Hapur, Gautambuddhnagar, Gaziabadand Baghpat comprises 45 blocks were covered and 1125 samples from different wheat varietieswere collected from all blocks of six Districts. During the survey of both year the percent disease incidence of karnal bunt was not exceeding the permissible limit (0.25%) of Indian Minimum Seed Certification Standards for quality seed production except Kanaksona (0.288%) from Bulandshahar District and 1085 (0.42%) from Meerut District which is more than the permissible limit of standards. In both year (2021-22 and 2022-23) of survey the maximum incidence (0.42%) of karnal bunt was recorded in 1085 variety of Meerut District and 0.141% in HD 3226 of Baghpat District followed by 0.288% in Kanaksona of Bulandshahar District and 0.110% in UP 272 of Hapur District, whereas the minimum incidence (0.007%) was recorded in DBW 226 of Bulandshahar District and 0.001% in UP 303 of Meerut District respectively. The incidence percent of karnal bunt was recorded nil (0.00%) in both the year of all varieties of Gautambuddh Nagar District. Confirmation of karnal bunt pathogen was determined by species specific primers in PCR and RT-PCR on the basis of Diagnostic Protocol (DP4) of International Standard for Phytosanitary Measures (ISPM 27). |
