Abstract

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

Abstract

Efforts were made for the management of okra yellow vein mosaic spraying with NSKS@5.0 per cent, which reduced maximum OYVMV infection by 89.4 per cent followed by neem oil @ 3.0 per cent and Bougainvilleas spectabilis (10.0%) 86.4 and 83.3 per cent, respectively in vitro. Whereas the minimum reduction over control (72.2%) was observed in case of Oscimum sanctum L.@10.0 per cent. Neem derivatives by virtue of their repellent, antifeedent and insecticidal properties against vectors indirectly interfered with viral transmission
