Effects of Fungicides, Plant Extracts and Bio Agent on Downy Mildew of Isabgol (plantago Ovata forsk.)

Isabgol (Plantago ovata Forsk.) is important medicinal plant. Isabgol crop suffers a lot due to fungal diseases. Among all diseases, downy mildew caused by Peronospora plantaginis Underwood is the most important and wide spread disease, which appears in severe form every year and causes extensive damage to the crop. Therefore, in vivo evaluation of eight fungicides, phytoextracts, and one bio-agent for management of downy mildew disease was carried out which revealed that, seed treatment (ST) with Metalaxyl (3g/kg seed) followed by three foliar sprays of Metalaxyl MZ (0.1 %) at 15 days interval initiating from appearance of disease was the most effective treatment with the least disease intensity (10.76 %) and yield increased by 26.02 per cent over control, followed by Fosetyl-AI (0.2 %) and Copper oxychloride (0.2 %) which recorded 14.00 and 15.25 per cent disease intensity with 18.01 and 16.42 per cent increase in yield over control, respectively
