Abstract:
This research work deals with the study of “In vitro efficacy of plant extracts against Alternaria lini (leaf blight of linseed)”. It is the second most important rabi oilseed crop and stands next to rapeseed-mustard in area of cultivation and seed production in India. Alternaria lini is a highly destructine pathogen. The disease caused by this fungus is characterized by leaf spot appearance on the plant leaves Small circular dark brown lesion with paler margin and yellow halo, usually circular in shape, first small and then enlarged to 2 to 3 cms in diameter. Leaf blight is one of the most economically important diseases world-wide. It affects every part of infected plant. Regular use of fungicide will be hazardous for the soil and humans as well. The lab experiment was analysed using C.R.D. (Complete Randomized Design) with three replications and eight treatments including six botanicals. Treatments like control (Untreated), Jatropha (5%, 8% and 12%), Tulsi (5%, 8% and 12%), Neem (5%, 8% and 12%), Neem (5%, 8% and 12%), Bougainvillea (5%, 8% and 12%), Gulmohar (5%, 8% and 12%) and Parthenium (5%, 8% and 12%)Observations were recorded at different time intervals at 72 and 96hrs for the mycelium growth of the pathogen and inhibition per cent. Jatrophaleaf extract @12%recorded lowest radial growth and highest radial inhibition (%) against Alternaria lini causing leaf blight of linseed (Linum usitatissimum L.). The results of present experiment are under Allahabad conditions as such more trials should be carried out in future to validate the findings.
