Abstract:
Maize is one of the most important cereal crops in the world agricultural economy, cultivated throughout the world in all the seasons. A roving survey for the severity and incidence of mycotoxin producing fungi was taken up in fields, storage as well as in markets of the major maize growing districts of Karnataka during 2017-18 and 2018-19. The maximum per cent severity was recorded in Gunnal village (14.29) of Koppal taluk and Kadamanahalli village (25.71) of Haveri taluk during 2017-18 and 2018-19, respectively. Concurrently, from 21 taluk, storages and markets were also surveyed for per cent incidence of mycotoxin producing fungi. Among the surveyed localities, maximum per cent incidence was recorded in the godowns of Sagara (47.20) and H. Hadagali (65.60) during 2017-18 and 2018-19, respectively. Overall the higher mycotoxigenic fungi contamination was seen in Shivamogga and Koppal districts, whereas least severity was recorded in Raichur. Clearly the present investigation provides the information to locate the areas with high prevalence and less prevalence of mycotoxin in maize growing districts of Karnataka.
