Maize (Zea mays L.) is one of the important cereal crops of the world and world’s third leading cereal crop, after wheat and rice. Maize is affected by various biotic and abiotic stresses. Among the biotic stresses, fungal diseases are one of the major constraints in realizing the potential yields of this crop. So keeping in view the importance of maize diseases a survey was carried out during kharif-2019, in order to study the incidence of post flowering stalk rot in 13 villages of four major maize growing districts of Telangana state, viz. Karimnagar, Khammam, Warangal and Rangareddy. The incidence of wilt in different areas surveyed was ranged from 27.0 to 76.8 per cent. The maximum wilt incidence of 76.8 per cent was recorded in Thimmapur village of Karimnagar district, followed by 65.6 per cent at Gundlapalli village of Karimnagar ditrict. The minimum wilt incidence of 27.0 per cent was recorded at Narsimhapuram village of Khammam district. The pathogen was isolated from the infected stem showing typical vascular discolouration symptoms by tissue segment method on potato dextrose agar medium (PDA). The associated pathogens were isolated and identified on the basis of morphological characters, in which 12 isolates of F. verticillioides and 5 isolates of Macrophomina phaseolina were recovered. During study F. verticillioides pathogen alone noticed in more than 60% of samples collected.
