Abstract: The study was carried out to know the status of Alternaria leaf spot of isabgol (Plantago ovata Forssk.) in Zone III-B of Rajasthan caused by Alternaria alternata and its management through fungicides. The disease intensity was maximum (36.00%) at village Bhadwa in Parbatsar and minimum (16.00%) in Dhankoli Village of Moulasar Tehsil in Nagour during Rabi, 2016-17. Among five fungicides tested in vitro and in vivo, propiconazole gave cent per cent inhibition of mycelial growth at 300 ppm concentration. Two sprays of propiconazole (0.1%) at 7 days interval from disease initiation was found most promising in reducing the disease intensity (68.17%) followed by azoxystrobin (66.24%).
